This is a small patch release to make the multicellular stage work again as there was a major bug that slipped into the previous release that completely prevented playing the multicellular stage.

Patch Notes

• Fixed multicellular cells after the first one immediately starting to die. This should make multicellular now playable again.
• Doubled decay of radiation when taking damage to reduce overall taken radiation damage once it starts
• Fixed units of compound types shown in the GUI for how many seconds the storage lasts
• Fixed extra horizontal separators being visible in the membrane tooltips
• Added safeguards against cell colony members with missing components, now those colonies are force disbanded to allow the game to continue
• Updated translations

Environmental interactions get a lot more varied in this new latest version of Thrive. The first major change is that there are now environmental tolerances to consider. This means that your species needs to be adapted to the conditions of the environment you want to live in: temperature, pressure, UV, and even the presence of oxygen. Also added are new environmental chunks like the radioactive chunk shown in the first image. It will cause damage to microbes that cannot resist radiation. Also in this release we finally have a fully finished thermosynthesis gameplay, though it might not be exactly fully balanced yet as we didnt get that much balance feedback on the public test build last week. And of course along with the major new features we have a ton of small tweaks, graphics and GUI improvements as well as bug fixes. One highlight is that we now have an exclusive fullscreen option which should help anyone wanting to play in fullscreen mode on Windows.

• Tutorial and Thriveopedia tips page improvements

Whats Next

Full Patch Notes

It is once again time for early testing of the next Thrive release, 0.8.1. This release has a lot of new gameplay features like environmental tolerances, radiotrophy and reworked thermosynthesis gameplay. And theres also the usual bunch of smaller changes. One other highlight is that there is now an exclusive fullscreen mode that should improve things for everyone on Windows who want to play in fullscreen. Please report to us if the one pixel border and slightly wrong resolution problems are gone now. This testing build is a bit more raw than we would have preferred as the environmental tolerances feature was literally finished just a few hours ago. So please dont be too harsh on it. But do report back how it changes the feel of the game. There is a known problem where the tolerances GUI gets messed up when loading a save made in the editor, so please dont report that again as we are aware of it. Also it is very easy to get into negative MP when using the tolerance sliders. There's been multiple reports about that already so we don't need more, thank you. To access the beta build, right click Thrive in the Steam client and in the properties opt into the "beta" branch. As usual please post any feedback you have on this test build on our forums or the comments below. We are especially interested in the current game balance as many of the new features havent had time to be balanced well so we expect them to be unbalanced currently. We will try to get the game balance as good as possible before the full 0.8.1 release in one week.

Get ready for another exciting update: Thrive 0.8.0 is here! Packed with visual upgrades, this release introduces reworked 3D models for organelles, fresh membrane textures, and improved icons to enhance clarity and aesthetics. The dynamic environments also see significant changes, with more balanced compound changes and vent eruptions. In the editor, two major tools make their debut. The organelle suggestion system offers strategic recommendations based on auto-evo, guiding players on which organelles will benefit their organisms evolution. And the split order tab which gives you precise control over ATP production by letting you customize the sequence of organelle reproduction, adding a new layer of strategic depth to cell development.
Give the new version a try now, or if you don't have Thrive yet there's a sale on Steam right now for 25% off, so this is the perfect chance to grab a copy if you dont have one already or to gift one to a friend. [previewyoutube=FKhdlzvRX90;full][/previewyoutube]

Thrive 0.8.0 is releasing in one week so the usual public test builds are here. It hasnt been too long since 0.7.1 but we are squeezing one more release into this year so there isnt much time left to make that goal. The major goal of this release was to complete all of the remaining 0.7.x roadmap items, which we have managed to do as is evident from being able to call this release 0.8.0. In addition to the general polishing work of the editor and microbe stage heres a few highlights: improved dynamic compounds, tweaked microbe visuals, added new editor features like controlling organelle split order and organelle adding suggestion. In addition to the new features weve fixed a ton of bugs and improved the AI code to better use recently added features. Also as a major feature the experimental Mac support is back! This means that for the first time in a year people on macOS can play the latest version of Thrive. This isnt yet a fully supported platform for us and as a result this build is not part of the Steam version but can be downloaded separately if someone on Mac is wanting to give it a go. Hopefully we can make the Mac version a fully supported platform next year. See here for a wishlist goal weve had for a long time for people to show support for wanting to Thrive fully support Mac. So if you are on a Mac and would like to see Thrive there, please make sure you've wishlisted Thrive and set your platform preference in the Steam options correctly to be counted. To access the beta, right click Thrive in the Steam client and in the properties select "beta" as the active beta version. As usual please post any feedback you have related to this build in the dedicated feedback thread or the comments below. We are especially interested in any game breaking bugs or regressions that have accidentally slipped in. We hope to correct as many of the found problems before the full 0.8.0 release as possible.

Brace yourselves for another feature-packed update: 0.7.1 is here! Along with enhancements to the various reports available to the player in the editor, a lot of visual improvements to our cells, backgrounds, icons, and textures are here. Furthermore, oxygen is now dynamically simulated, being introduced by photosynthetic life forms on your planet. This has an immense effect on gameplay and progression throughout the Microbe Stage. Your organism, which now starts its journey on an anoxygenic world, must now strategically evolve its metabolism around the pace at which oxygen is introduced to your atmosphere. A significant chapter in Thrives development has begun the introduction of a changing, scientifically accurate world that evolves with the life on your planet!

Thrive 0.7.1

The time to test 0.7.1 is here! This release was almost called 0.8.0 as most of the 0.7.x roadmap is now complete, but a few items are left. The most immediate noticeable thing in this release is that the world will start off without oxygen and only get oxygen after photosynthesis is evolved. That has required various tweaks all over the game to keep things working nicely with the new starting conditions. Theres also a ton of the usual small changes, features and bug fixes. Theres also some new microbe stage visual effects that can be enabled in the options menu. If people like these, they may become default options in the future. This beta version is available as the beta branch on Steam (right click Thrive in the Steam client to be able to select that version to play). Please provide any feedback you have about this new upcoming release, we are especially interested in any major game breaking bugs that we have not found yet. You can provide feedback in the comments below or in the thread on our forums: https://community.revolutionarygamesstudio.com/t/0-7-1-release-candidate-testing/7810

Continuing the momentum from our previous update, many new features have been added to Thrive which will enrich the player experience. Symbolizing another monumental step forward towards a complete Microbe Stage, we present to you Thrive 0.7.0! This release marks the completion of the 0.6.x roadmap. For this release the major features are a new auto-evo algorithm based on miches that should generate much better AI species, and a convolution surface algorithm which gives macroscopic creatures a skin in the prototypes. Theres also a lot of smaller new features and tweaks to the microbe stage as usual. The last roadmap items to be completed where engulfing balancing and fixing as well as allowing continuing as a related species in easy mode.

Thrive 0.7.0

Convolution Surfaces Realized

Auto-Evo Reimagined

Expanded Cellular Gameplay

Compound Clouds Revisited

Other Notable Changes

• In the experimental features mode, placing rusticyanin allows the player to shoot projectiles at iron to break off chunks, which will eventually result in the larger iron chunk being depleted fully. Enabling experimental features will allow players to test this out; feedback would be much appreciated.
• Migration has been revamped, allowing the player to direct their species towards a new patch without necessarily playing in that patch themselves.
• On easy mode, players can now switch to another species upon extinction.
• Corpse chunks now have more resources, making heterotrophy more viable. Chunks spawning and despawning has also been refactored to result in more consistent performance.
• You can now engulf when starving, though you take health damage.

Looking Ahead

Full Patch Notes

• Added a completely new auto-evo algorithm based on a miche algorithm. This should massively improve the species auto-evo generates.

• Added more instructions regarding gettext to our setup instructions
• Updated translations

The upcoming Thrive release 0.7.0 marks the end of the 0.6.x series of releases as we have completed all of the roadmap items. This marks a major milestone towards the completion of the microbe stage. As usual we are making a public test version available to make sure the release can be more polished. The most major change is a new auto-evo algorithm that should vastly improve the AI species. Theres also a ton of small new features and tweaks in the microbe stage. Finally wed like to highlight a feature made by a new contributor to the game: convolution surfaces are finally here! This means that in the macroscopic prototype theres now a skin wrapped around the metaballs which will give much more of an impression of what the end goal of the visuals for that stage of the game are. This beta version is available as the beta branch on Steam (right click Thrive in the Steam client to be able to select that version to play). Please provide any feedback you have about this new upcoming release, we are especially interested in any major game breaking bugs that have snuck in. You can provide feedback in the comments below or in the thread on our forums: https://community.revolutionarygamesstudio.com/t/0-7-0-release-candidate-testing/7673

This is a quick small patch release to fix a few major issues that were resolved since the last release. The most major fix is that many more older CPUs should be able to run Thrive now. This problem was caused by a build configuration setting unintentionally targeting much newer CPU instructions than intended. You can find the major updates in 0.6.7 in the previous news post.

Patch Notes

• Changed compilation options for the fallback native library that should now work on older CPUs that only have SSE 4.2 and no newer instructions
• Fixed the game getting stuck when selecting 32 native executor threads
• Re-enabled Harmony mod loading as this no longer seems to cause the game to get stuck on start up with Godot 4
• Reduced unnecessary StringName allocations related to key prompt icons and checking pressed inputs
• Updated YamlDotNet from 15.1.6 to 15.3.0
• Updated Jolt Physics Engine version
• Updated translations

With the slew of backend changes from previous updates now finally done and out of the way, development was centered entirely on the development of new features for the past few months. And now, with the release of Thrive 0.6.7, we bring you the long awaited endosymbiosis feature, toxin customization, ferroplast organelle, and much more!

Thrive 0.6.7

Day & Night Fully Implemented

Endosymbiosis

Ferroplast Organelle

Expanded Toxin Varieties

Other Notable Changes

• Buffed cell corpse chunks
• Added alternative unlock condition for oxytoxisome that unlocks it after dying multiple times, this models how prey species can become toxic instead of only predator species having access to toxin
• Added custom inventory item drag icons and updated land tree placeholder model
• Added a display in the editor showing how long each compound takes to fill up, this will hopefully help in planning for how to survive the night with enough resource generation during the day
• Made auto-evo consider surviving the night more to penalize species with not enough storage or resource stocking up during the day
• Created a new custom model for ice chunks to be separate from the particle effects also present in the patch
• Added custom model and icon for injectisome upgrade

Looking Ahead

Full Patch Notes

• Implemented endosymbiosis. It is now possible to engulf other species to turn them into free organelles and also to unlock those organelles in an alternative way compared to the normal unlock conditions.
• Added customization for toxin organelles to select various toxin types that have different effects than oxytoxy
• Added different colours for different toxin types
• Day/night cycle is now enabled by default but can still be turned off
• Added ferroplast organelle, which is the eukaryotic variant of rusticyanin
• Cells spawning close to night time (or during night) get extra resources to help them survive the night
• Buffed cell corpse chunks
• Added alternative unlock condition for oxytoxisome that unlocks it after dying multiple times, this models how prey species can become toxic instead of only predator species having access to toxin
• Added custom inventory item drag icons and updated land tree placeholder model
• Fixed auto-evo mutations code using exceptions for normal flow control, this fixes at least one identified case where the game would freeze completely
• Fixed compound bars when max storage amount is less than 1
• Fixed fluid currents system force not applying, this bug was likely present ever since the ECS refactor
• Fixed iron chunk collision model scaling and fixed their rotation differences compared to the visual models
• Fixed HUD messages font shadow not working
• Fixed a brief flash of the game when exiting the freebuild editor for the first time
• Fixed multiline text edit style not working correctly
• Fixed cheats being able to enable the editor button when already going to the editor which allowed causing a crash in the game by clicking the button again
• Fixed some problems related to multicellular species trying to enter binding mode
• Made AI cells that depend on resources that aren't present during the night be more sessile during it
• Added new GUI and warnings to the editor to show if storage space and compound production during the day is enough to survive the night for photosynthesisers
• Added a display in the editor showing how long each compound takes to fill up, this will hopefully help in planning for how to survive the night with enough resource generation during the day
• Made auto-evo consider surviving the night more to penalize species with not enough storage or resource stocking up during the day
• Created a new custom model for ice chunks to be separate from the particle effects also present in the patch
• Added support for organelle upgrades overriding the base model of the organelle, which will be used more in the future
• Added custom model and icon for injectisome upgrade
• Added custom physics time to metrics panel, this feature was done last December but somehow forgotten to be added until now
• Added support for loading more shape types to our physics engine integration in preparation for use with organelle shapes
• Created custom collision shapes for all organelles to finally properly fix them
• Tweaked glucose reduction effect code a tiny bit to be clearer
• Made orphaned node count in metrics panel ignore intentionally cached nodes
• Improved organelle model data handling to keep model path variables and scenes in a single data container to avoid future mistakes with mixing up data for different scenes
• Fixed some code warnings and fixed a bug in metaball moving that this uncovered where the parent metaball reference was not updated correctly
• Removed unused thermoplast mesh file
• Updated Jolt Physics engine
• Updated YamlDotNet from 15.1.2 to 15.1.6
• Updated xunit from 2.8.0 to 2.8.1
• Updated code checking tools
• Updated translations

After a few releases thin on new features this version of Thrive has focused purely on new features. The main 3 major new features are: endosymbiosis, day/night cycle enabled by default, and toxin customization. These add much more variety to the microbe stage and hopefully make the game significantly more enjoyable. Endosymbiosis allows you to create an endosymbiont organelle from another species giving a free copy of that organelle and unlocking placing that organelle. Day/night cycle has been polished up with some new GUI features in the editor to make it easier to determine if you can survive the night and as such is now enabled by default. The toxin customization feature allows using different toxin types that have different effects for more interesting toxin gameplay. Besides the major features we also have a variety of smaller changes and bug fixes (including one fix for the game freezing during gameplay). To play this early test build you need to right click Thrive in the Steam client and in the properties select "beta" as the version to play. Please provide any feedback you have about this new upcoming release, we are especially interested in feedback related to balancing of the new features as well as any major game breaking bugs. You can provide feedback in the comments below or on the dedicated thread on our community forums: https://community.revolutionarygamesstudio.com/t/0-6-7-release-candidate-testing/7497

Here is another very quick patch release to address one major bug that prevented playing normally. This release now fixes the patch extinction screen not being properly sized, which made using that important part of the game very difficult.

Patch Notes

• Fixed the size of the patch extinction screen
• Updated translations

This is a quick patch release to address some of the biggest issues with the previous release. This doesn't fix every single issue report we got after 0.6.6 as many of the issues still don't have known root causes and wouldn't be easily fixable in a small amount of time. The biggest visible things are the fixed organelle models as well as fixing the size and position of many GUI elements. The version of the included Thrive Launcher was also recently updated. This new launcher version will now show a warning if the current CPU is detected as not being suitable for running Thrive. Please continue reporting any bugs with loading saves or the game locking up (as we'll need more information to track down this problem).

Patch Notes

• Fixed organelle models looking bad in Godot 4
• Improved the visuals of the chemoreceptor and tutorial lines
• Turned off compression on the clouds perlin noise texture which was accidentally turned on with the Godot 4 update
• Did some minor organelle visuals tweaks
• Organelle placement sound is now only played if a placement action was done (fixes it being played for organelle removal)
• Fixed evolutionary tree zooming in and out not working correctly
• Fixed screen effects in miscellaneous settings not working
• Fixed win and extinction screens
• Fixed various GUI popup related problems in the later prototypes
• Increased audio latency to 20ms which helps crackling audio if the game was running slightly too slow
• Added extra error handling to Thriveopedia load and save load against scene load failures which seems like a randomly occurring bug in Godot 4 engine itself
• Added extra safety checks around native library load and printing of current CPU name if it is not detected as sufficient for running Thrive
• Added extra checks to our simulation running code to maybe start to narrow down a few bugs
• Redid modal manager connect and check operation to hopefully fix one case of signal connection errors printed in Godot 4
• Fixed position of our links popup in the main menu
• Other GUI fixes
• Added hyperthreading throttling instructions to our busy-wait loops
• Our CI builds system works again
• Updated our automated code checks to work on Windows again
• Removed trailing spaces in shaders that Godot did automatically
• Added game export script flag to ignore problems with installed Godot to just try to export anyway
• Updated Nix flake to use Godot 4.2.2
• Updated xunit from 2.7.1 to 2.8.0
• Updated translations

After over a year since Godot 4 was released, Thrive has finally made the huge leap to go from Godot 3 to 4. This release is sadly thin on new features as Godot 4 is so different from 3 that it took a lot of time to go over everything that needed to be updated to work with Godot 4, as the automatic upgrade process was missing a ton of things. Also we needed to bugfix and tweak a lot of our code that relied on how Godot 3 worked which was changed in 4.
This conversion didnt require us to fix the gameplay once again thanks to the ECS rework that was done last year. That protected our gameplay code from all of the Godot changes. A lot of the GUI needed to be tweaked and fixed, though. This upgrade to Godot 4 now allows us to use a modern C# runtime and language version features. As an added bonus the new runtime has increased the game performance. While Godot 4 initially looked like it made the game a bit slower, that runtime upgrade should have the net effect of the game being again just a bit more performant. All this background work is setting up for the future of Thrive. For the next release well get back to working on microbe roadmap features so hopefully everyone can have a bit more patience with us before we can bring out some new major features. Unless of course an overwhelming amount of new high priority bugs are discovered after this release, but heres hoping that that doesnt happen.

Godot 4.2.2

Engulfing Animations

Varied Environmental Conditions

Other Notable Changes

• Theres now a native library variant that doesnt require AVX, this should make Thrive playable again on some older CPUs
• Osmoregulation cost values are now shown in red as it is a negative property
• Engulfment storage full tutorial now has an end trigger once the player has digested enough things
• Memory usage metrics now works on Windows
• Removed our custom checkbox implementation now that Godots has all the needed features

Looking Ahead

Patch Notes

• Updated to Godot 4.2.2 (we were previously on 3.5 so this is a massive upgrade)
• Updated to .NET 8 runtime and C# 12 as it turns out this can be used with Godot 4
• New engulf animation that creates wave lines instead of the old just flashing blue animation
• Oxygen now has different levels in different patches which affects the utility of certain parts a ton
• There's now a native library variant that doesn't require AVX, this should make Thrive playable again on some older CPUs
• Arabic fallback font had to be removed as it caused buggy line heights in all text in Godot 4
• Osmoregulation cost values are now shown in red as it is a negative property
• Engulfment storage full tutorial now has an end trigger once the player has digested enough things
• Fixed new player species name not immediately applying after exiting the editor
• Fixed new cell button crashing multicellular freebuild editor
• Fixed data cache disposed errors that only seemed to trigger in exported version of the game
• Fixed no changes in editor tutorial being able to prevent multicellular editor exit
• Memory usage metrics now works on Windows
• Fixed CPU check only checking AVX and not AVX 2 which was then used anyway causing a crash on CPUs that have AVX but not AVX2
• Switched the AVX feature check to use standard C# function, which is hopefully more accurate than the previous approach that we got reports about false negatives
• Tweaked wording on the fallback opengl renderer use and disabled the 3D backgrounds again for that as they still aren't fully correct
• Updated our colour picker customizations for Godot 4 (pick from game window seems to not work currently on Linux)
• Removed our custom checkbox implementation now that Godot's has all the needed features
• Switched from the previously used tar compression library to C# standard one which shouldn't have any save corruption issues (due to this we were stuck on an old version of the compression library)
• Added check to tools against omitting part of a version number this removes potential for a mistake that almost was in 0.6.5
• Added simple C#-code-only unit tests for a few things
• Converted some things to use direct references instead of NodePaths
• There's now a nix flake for Thrive developers
• Updated our documentation impacted by the upgrade to Godot 4
• Updated Jolt physics engine to newest version
• Updated YamlDotNet fro 15.1.1 to 15.1.2
• Updated AngleSharp from 1.1.0 to 1.1.2
• Updated code checking tools version
• Updated translations

Thrive has updated from Godot 3 to Godot 4. This engine upgrade has caused a ton of problems, but the game is now back to working well enough that a new release can be made. This is the usual early testing build before a release. The gameplay should be the same as the previous release but there are some small graphical artifacts on organelles. And there might still sadly be a game lock up problem where the game just freezes and no longer does anything at all (gameplay is frozen and GUI cant be interacted with either). If anyone sees this happen, please let us know. Hopefully this is not too prevalent of an issue that would prevent the release. Status of the Godot 4 conversion along with all still known issues is here: Godot 4 Board For audio crackling issues or the game not starting due to missing Vulkan, there are new options for starting Thrive in the Thrive Launcher that might help with these problems. Any experiences, either working or not working, related to these options would be great to hear about. This version is available through Steam as the beta version (right click the game and select the beta in the properties). Please let us know if there are things you notice that are now worse in this version than in 0.6.5. But please check first that no one else has mentioned the same thing in this thread yet. If you have any feedback about this version please share it below or on our forums: https://community.revolutionarygamesstudio.com/t/0-6-6-release-candidate/7421

Another few months, another Thrive update full of game-changing new features and improvements! Headline features of Thrive 0.6.5 include organelle unlocking mechanics and fog of war for the patch map, adding more elements of progression to our evolving gameplay loop, together with further performance enhancements on top of those made by the rework last release. [previewyoutube=Hg6jv75cbgU;full][/previewyoutube] Following the relatively feature-light release of Thrive 0.6.4, Thrive 0.6.5 brings you some major updates in mechanics that should make the whole game a more satisfying experience. See our patch notes at the end of this post for full details, or read on for some of the highlights.

Organelle Unlocks

• Being in a patch with a certain amount of a compound.
• Having another organelle in your cell for multiple generations.
• Engulfing a certain number of other cells.
• Having a certain amount of excess ATP production.

Patch Map Fog of War

Further Performance Improvements

Expanded Thriveopedia and Tutorials

Other Notable Changes

• Auto-Evo predictions in the editor now show energy first and population second. This should reduce confusion over population reductions due to larger individual cell size despite higher energy gained.
• Hovering over a species name in the patch map (in the editor or Thriveopedia) shows a preview of that species. Weve found this very handy for understanding what prey and perils await you in nearby patches!
• New music track exclusive to volcanic vents.
• Reimplemented pilus damage cooldown to prevent cells dealing way too much damage.
• Added hotkeys for the macroscopic editor in later stage prototypes.
• Late multicellular speed now depends on the number of metaballs with myofibrils.
• Plenty of small fixes and additions.

Looking Ahead

Full Patch Notes

• Implemented fog of war for the patch map, you now need to explore the map to find all the patches that exist
• Added part unlock system. Some organelles are now locked until the player fulfils certain conditions.
• Added multithreaded running of ECS systems. This improves the performance a bit more on systems with enough CPU cores.
• Reduced memory allocations during normal gameplay by 75%
• Auto-evo prediction now shows the gained energy first and population second
• Hovering over a species name in the editor report now shows an image of the species in a tooltip
• Added button to eject all engulfed things, helpful when you have ingested too poisonous prey
• Thriveopedia now has inter-page links and external links
• Added a button to open an organelle's Thriveopedia page when hovering over the organelle
• Added multiple new microbe stage tutorials and reworked many existing ones as well as changed the tutorial flow in the editor
• The initial tutorial message is now customized based on the life origin selected in the new game options
• Added a new microbe stage music track that is exclusive to the vents biome
• Reduced bacteria swarm spawn counts for larger bacteria to try to balance large swarms of killer bacteria that clear out all smaller species
• Reimplemented pilus damage stab cooldown when dealing large amounts of damage at once, hopefully to prevent ejected cells from very quickly killing their engulfer
• Previous gathered energy is now shown in the prediction tooltip for comparing to see how much the increase/decrease is
• Did some further small system tweaking based on profiling for a bit more performance
• Increased minimum entity counts a bit now that we have more game performance
• Reduced density of big iron chunks to make them pushable by cells again
• Fixed big iron chunks having their collision models rotated differently than the visual modes (this caused the visuals to now be rotated differently than before until someone can remake the model)
• Added explicit check for available CPU features and making the game exit cleanly if the current CPU is not new enough. This is implemented through a small library which is loaded first and only after confirming things are good loading the main native code of Thrive is done.
• Improved the handling of native library load not succeeding and the game needing to close (this shouldn't be a hard crash anymore)
• Made compound cloud creation use interlocked operations rather than locks to slightly improve performance
• Added middle mouse button for panning to the list of rebindable keys
• Middle mouse button can now be used to pan in the society stage
• Made the move and delete hotkeys work for macroscopic editor
• Late multicellular speed now depends on the amount of myofibril metaballs
• Added a cheat for unlimited growth speed
• Cells now stop emitting mucilage when joining a colony, this should fix a really old reported bug
• Tweaked auto-evo prediction GUI a bit to give more horizontal space for numbers
• Fixed bug with colony member attach positions sometimes being incorrect which has been a bug for a really long time (note that this is different from multicellular body plan change bug)
• Fixed engulfing used storage not taking things currently being pulled in into account leading to overuse of storage and ejection
• Fixed engulfing not taking targets being in colonies into account, now the lead cell is no longer always yanked out of a colony
• Fixed regression in previous Thrive version with multicellular growth buff not working leading multicellular growth to be half the intended speed
• Fixed regression in entering engulf mode in a colony where other members could engulf but the player couldn't
• Fixed editor button not re-enabling after exiting a colony
• Fixed some bugs related engulfable being stuck with 0 contents, at least infinite toxin damage should be fixed
• Fixed a crash when accessing incorrect cell colony member index due to one missing "=" character in the code
• Fixed Thriveopedia map not displaying if opened before going once to the editor
• Fixed slime jet activation only playing a single frame of animation, now a full animation cycle is always completed
• Fixed bug with visual system setting Godot scale directly when a separate system should be doing it
• Fixed microbe sound effects continuing after cell death
• Fixed mouse click not working regression in signaling agent command wheel
• Fixed toxin projectile visuals not loading properly from saves
• Fixed fossilise buttons not updating their state when a species was fossilised, now the buttons correctly show the species as being fossilised
• Fixed bugs with body plan editor and cell editor displaying their graphics at the same time
• Fixed the 3D environment colour leaking into the cell editor in multicellular editor (the background is now disabled while in the cell editor and enabled when returning)
• Fixed saving not working in the editor if a save made in the editor was loaded and the stage was not entered in between
• Fixed an error being triggered when exiting from a save loaded in the editor without going to the microbe stage before quitting
• Fixed the metrics panel entity counts not making much sense with the ECS changes
• Added option to turn off the multithreaded world simulation in case it is slower or has other issues
• Added new setting to control the number of native executor threads (affects physics performance)
• Added some more models to the list in the gallery
• Added some extra safety checks to task executor based on one recent crash report
• Added some safety code to ensure ejected cells will despawn in a few seconds if they are dead
• Added safety code against entities being stuck in dead engulfers, instead the engulfing state is now properly cleared
• Added safety checks in editor enter button state apply to ensure the player hasn't died during the one frame it takes for the state change to apply after it is triggered
• Added code to force all cells into normal mode when they are engulfed to make sure engulfed cells can't be in weird states
• Added a check to ensure gas compounds add up to 100% in biomes
• Made the benchmark get progressively more intensive to ensure it should always eventually end
• Removed protoplasm from the game, it was an old buff for AI bacteria cells
• Removed a few unnecessarily saved fields from save files
• Added debugging feature to draw debug lines easily
• Added debugging helpers for verifying ECS component access patterns
• Wrote an overall Thrive ECS architecture describing document
• Implemented dependent entity delete for future use in Thrive
• Added .mo files to gitignore to stop people accidentally sending those in PRs
• Updated our scripts to run on .NET 8
• Fixed a few problems in the setup instructions (.NET 8, gold linker), added more info on submodules
• Updated code style rules and checking tools
• Added a styleguide section on avoiding memory allocations
• Removed unused code constants
• Renamed an interface in the code to clarify its purpose
• Renamed UsedIngestionCapacity to UsedEngulfingCapacity in the code to improve clarity
• Setup dependabot to automatically update our git submodules
• Some native side code build options improvements
• Applied our single letter LINQ lambda style across the codebase
• Updated AngleSharp from 1.0.7 to 1.1.0
• Updated YamlDotNet from 13.7.1 to 15.1.1
• Updated Jolt physics engine
• Switched translation files to no longer have source reference lines, this should reduce merge conflict amount massively, but most translation tools don't know how to look at the translation template file to find the reference line information
• Updated translations

Thrive 0.6.5 will be released next week and as such the usual early test build is here. This should be a more normal testing version compared to the one for 0.6.4 with a lot less radical changes included in this version. This version mostly focused on improving performance with not redoing almost the entire game logic. The most major new features re the fog of war for the patch map and organelle unlocks. If you test this version you can let us know how the game performs now. Please include info on how many threads was used and if game simulation multithreading was enabled. Slightly tweaking those settings may change the performance a lot which would help us pick good defaults if we get reports from multiple people how those impact things. This beta version is available as the beta version through Steam (can be selected in the Steam client game properties) If you have any feedback about this version please share it below or on our forums: https://community.revolutionarygamesstudio.com/t/0-6-5-release-candidate-testing/7288 Especially if any game crashes or lockups are found please report those along with saves / steps on how to trigger the problem and well make sure those problems are taken care of before the full 0.6.5 release.

Having just released our performance refactor update 0.6.4, we quite quickly became aware of a large amount of bugs and other issues brought up by our players. Thanks to everyones help and reporting, we were able to track down the source of many of these bugs and patch them up with care. The resulting patch has just been published today, and should result in a significantly more stable experience for our players. With the bulk of these bugs now dealt with, we should be able to begin focusing on the contents of our next update soon enough! Unless of course we still get many new bug reports after this patch.

Patch Notes

• Balancing improvements: movement speed for larger cells was increased a bit, bacteria can now again spawn in larger swarms than just 2 at once, and debuffed colony movement bonus a bit to make sure colonies aren't faster than individual cells.
• Added better tooltips for microbe action hotbar and become macroscopic button
• Added panoramic 3D backgrounds for late multicellular editor. Before they were used just for the stage itself.
• Fixed cells not appearing at all when using low thread count. The same root cause also caused cell rotations to stop working after some time in the game.
• Hexes placed in previous editor session are now slightly darker to make them actually visually distinct
• Engulfing animation now correctly stars from the engulfed object's world position
• Fixed eukaryotic size bonus for engulfment not working
• Fixed new health max not applying after exiting the editor
• Fixed engulfing pulling in animation playing twice in a row
• Fixed engulfing endosome graphics scale blowing up a ton when engulfing a specific object type
• Fixed engulf eject animations not working at all
• Fixed a crash related to despawning engulfed objects
• Fixed a save error when a species had a chemoreceptor set to detect that species it was in
• Fixed incorrect data being generated for multicellular body plan indexes which lead to a crash when colonies regrew lost cells
• Fixed tutorial about leaving colony to be able to enter the editor being able to trigger in early multicellular stage
• Fixed the reproduction bars staying white if the player died when the editor was available. Also with the same change compound bars will only update while the player is alive.
• Fixed softlock when pressing the editor button but the player was in a microbe colony (not multicellular)
• Fixed Godot warning that was printed when the editor was exited (this was from the options menu sound device list)
• Fixed a Godot error when shutting down the game that was caused by PhotoStudio
• Fixed crash in early multicellular stage related to organelle repositioning when exiting the editor
• Mostly fixed microbe colony member positions. Members bound 3-4 cells away from the lead cell still have some rotation and positioning issues.
• Made multicellular lost cell tracking ignore cells that no longer pointed to a valid cell index in a species' body plan. Most likely caused by removing cells from the body plan after that cell colony was spawned.
• Going to the art gallery now disables the 3D menu background performance tracking which should fix unintentional low performance detection due to a lag spike
• Removed old evolutionary tree build error message that should not be able to trigger anymore as we have had a save breakage point
• Made speed cheats work much better, especially for larger colonies which got way too much bonus speed
• Unified the cases of our JSON files, properties are now PascalCase everywhere (with internal names still keeping camelCase naming)
• Fixed native library symbol upload script
• Updated Nito.Collections.Deque from 1.1.1 to 1.2.1
• Updated translations

For five entire months straight our developers have worked and toiled to bring about a massive rework in the functionality of Thrives background processes. A massive undertaking that has left nothing untouched, and everything entirely different. This is without a doubt a fundamental change in the underlying rules of reality in the world of Thrive; A brand new physics engine complete with better performance. Nothing will quite feel the same as it once did, but its still Thrive, and it can only get better. In focusing on this grand refactoring, we regrettably have little to show on the gameplay side of things, but it will be smoother sailing from here on out.
[previewyoutube=TxSrcFVlqjY;full][/previewyoutube] Our developers have worked hard to bring you an expanded Thrive experience. Weve outlined the major changes in this devblog, but you can see the patch notes at the end for a full list of features and bug fixes.

Performance Like Never Before

A Guide To Thrive

New Part Customization

Other Notable Changes

• Added two new context specific microbe tracks that can play instead of the normal microbe ambiance when in those specific patch types.
• Fixed two very common multicellular crashes: InvalidOperationException: Sequence contains no matching element and ArgumentException: OrganelleTemplate cant be placed at this location.
• When low performance is detected in the menu the game will now prompt the player to disable the 3D menu backgrounds.
• Improved the visuals of the organism statistics panel and added / updated related tooltip icons as well.
• Multicellular colonies now use absolute positioning of members set by the editor. This isnt perfect (leaves gaps) but the problem with cells growing at the wrong positions randomly should be gone now.
• Membrane data generation now happens in a background thread to reduce stuttering happening while cells spawn.
• The AI will now avoid engulfing something it cannot digest, though they may still try occasionally. Depends on behavior values.
• Theres now a tutorial for the become multicellular button as many players seemed to not realize it was a button.

Looking Ahead

Patch Notes

• Refactored the entire microbe gameplay code to use an Entity Component System (ECS) architecture and a different physics engine (Jolt). This took up the vast majority of the time spent on this release. As a result of this many things in the game will feel slightly different and there will definitely be new bugs that have slipped past us. We will attempt to quickly fix any new bugs introduced with this change.
• The game performance is now 20-100% better than before thanks to the ECS and physics rework (different benchmark parts have different improvements, and different gameplay conditions also have different performance gains)
• Improved auto-evo performance by about 50%
• Added a native C++ library for Thrive that has the physics engine integration for now but we can in the future move computation heavy parts of the game there that might benefit performance
• Added two new context specific microbe tracks that can play instead of the normal microbe ambiance when in those specific patch types
• Added Thriveopedia pages for each of the organelles currently in the game
• Fixed 2 very often reported multicellular crashes: InvalidOperationException: Sequence contains no matching element and ArgumentException: OrganelleTemplate can't be placed at this location
• When low performance is detected in the menu the game will now prompt the player to disable the 3D menu backgrounds
• Improved the visuals of the organism statistics panel and added / updated related tooltip icons as well
• Chemoreceptor can now be upgraded to detect cells of a certain species
• Added vacuole upgrade to specialize it for a certain compound. Specialized vacuole stores double the normal amount of the specialized compound but provides no storage for other compounds.
• The pilus now applies damage based on the physics penetration amount instead of always a fixed value. Faster collisions result now in more physical damage.
• The pilus can now be upgraded to an injectisome to switch the damage to be toxic (instead of physical) and also to apply the full damage no matter how light the hit is
• Microbes now use the physics engine to turn which should result in reduced rotation related bugs or slight issues
• Microbe physics shapes are now a single convex body which performs better and it much more closely matches the visual size of the membrane
• Microbe colony physics shape is now a single combined body. This should fix rare bugs with pili detaching or toxins hitting self when firing them.
• Multicellular colonies now use absolute positioning of members set by the editor. This isn't perfect (leaves gaps) but the problem with cells growing at the wrong positions randomly should be gone now.
• Membrane data generation now happens in a background thread to reduce stuttering happening while cells spawn
• Added a tutorial for negative ATP balance
• The AI will now most of the time not try to engulf something it cannot digest
• The AI will now remember what it was doing before a save thanks to the component data being easier to load fully intact
• Added 3D panorama backgrounds for various patch types for the late multicellular underwater part. These were completed a while ago but were never accessible in game until now.
• There's now a basic page name search in the Thriveopedia
• Improved initial compound handling for multicellular colonies
• There's now a tutorial for the become multicellular button as many players seemed to not realize it was a button
• Duplicating a cell type now selects it in the early multicellular editor
• Becoming multicellular now has a timeline entry for permanent record when it happened
• Added early multicellular freebuild mode
• Organelle chunks that are dropped now stop playing animations (for example flagellum swim animation)
• Fixed the most often reported crash, which was likely due to Godot integration with Bullet physics, by switching physics engines
• Fixed subshape out of range errors from physics also thanks to entirely redoing the gameplay physics
• Fixed the osmoregulation editor tooltips not updating based on the difficulty and current membrane
• Fixed the AI shooting too early at a target it wasn't pointing at yet due to rotation no longer being almost instant
• Fixed bug with glucose reduction showing up sometimes as NaN
• Fixed the global timeline not showing populations correctly
• Fixed a bug with incorrect resulting MP in early multicellular from incorrectly calculated actions on separate cell types
• Fixed saving bug with ObjectDisposedException with HostileEngulfer
• Fixed an exploit with deleting and duplicating cell types giving infinite MP
• Fixed a crash when double clicking on organelle move
• Fixed organelle popup menu not being tall enough with certain languages selected
• Fixed symmetry trying to place multiple unique organelles
• Fixed a crash when loading a save while load was already in progress (the new load is now prevented until the previous save/load operation completes)
• Fixed the auto-evo exploring tool map not panning to show the selected patch initially
• Fixed keyboard navigation in input options
• Added one more fix (the 4th) now against accidental cannibalism (when turning multicellular)
• Added multithreading to microbe growth, made easier thanks to the ECS architecture
• Improved externally positioned organelles to use much less CPU time
• Various disposed object exceptions should no longer be possible to happen with the gameplay no longer using Godot Nodes to implement it

We had a beta build last week, and quite expectedly it had a bunch of problems. Weve spent the last week fixing as many of them as possible. Right now there shouldnt be any blocker issues on releasing 0.6.4 and as such it is scheduled for next week. For now there is a public test build to just to make sure that the release will be good enough quality as it is always the case that random people find bugs we developers have not seen at all. The new test build is available as the beta version through Steam (selectable in the Steam client game properties). It has various improvements over the previous public beta test. Here's a short list of the most major things:

• New feature: mucilage can be selected for vacuole storage specialization
• Reimplemented early multicellular, game should be playable again all the way through the prototypes
• Buffed base movement, especially for larger cells, set slightly even higher microbe physics damping
• Massively buffed mucilage jet speed
• Reimplemented organelle render order to get things to look more like they should, especially when engulfing
• Reimplemented pulling cilia so that it no longer crashes the game, it's just a bit unbalanced
• Various colony damage and engulfing fixes
• Fixed saving and loading with cell colonies
• Fixed pilus damage not working at all
• Fixed engulf size not re-applying after cell grew or was edited
• Fixed multiple engulfing related bugs (still at least one bug left with indigestible things getting stuck inside)
• Fixed engulf progress indicator going up to 200% also fixed "devoured" text not appearing
• Fixed a crash with certain entity types existing and not having expected materials
• Fixed immediate crash when going to the ice shelf patch
• Fixed various other bugs and crashes
• Added submodule info to packaged source code
• Updated translations

It has been quite a while since the last update to Thrive. The reason why is that we've been hard at work switching the game to a new physics engine and converting all of the gameplay code to an ECS architecture. This improves the game performance significantly, which has been a long standing complaint that we are addressing with these very drastic measures. The game code refactoring has been a huge amount of work but hopefully the game performance gains (and future performance gains that these changes allow but didn't make it into this release) make the delay in new feature development worth it in the end. The game still has unconverted parts and many smaller issues, but the microbe stage is now mostly playable. In order to ensure we do not release a really broken version we have made a public test build of 0.6.4. This is available as the "beta" version through Steam (can be selected in the game properties in the Steam client). We would greatly appreciate any and all reports of crashes, unusual behavior, and other bugs you might discover. Please give us instructions on how you managed to break something! As that will be very crucial in cutting down on the time it takes to fix any of the found problems. Please note that if you reach the early multicellular editor and exit it, it is totally expected that the game will crash as that is the still unconverted part of the game. If there aren't too many major problems found, 0.6.4 will release next week, with likely a patch 0.6.4.1 following it before the Christmas holidays. If things don't go well it might still be multiple weeks until 0.6.4, but we are working very hard to get a new version of Thrive out before the end of the year. We have a dedicated thread for keeping track of all of the reported problems on our community forums, where we will be much more likely to notice any reports about issues than elsewhere: https://community.revolutionarygamesstudio.com/t/beta-testing-of-thrive-0-6-4/7027

Glimpse the future of your species in the latest release of Thrive! Now including prototype versions of all planned stages going all the way to the very end of the game. For the first time ever, your species can now experience the entire journey from single cell to galactic empire, and at the very end, return once again to where it all began. All this and more, in the release of Thrive 0.6.3.

0.6.3 is releasing in a bit over a week so here's a surprise early release candidate test build due to midsummer. The upcoming release adds all of the remaining prototypes for game stages that weren't ready in time for the previous release. Besides those there are a bunch of small fixes and feature improvements for the microbe stage and general GUI parts. You can play the RC now by switching to the beta version on Steam (right click on Thrive to access properties). You can leave feedback in the comments below or on our forums: https://community.revolutionarygamesstudio.com/t/0-6-3-release-candidate-testing/6619

Take your species further than ever before with the newly optimized cellular stages that will smoothly take you sailing into our latest advancements in the prototype stages! No longer are the creatures of Thrive strictly confined to the underwater realm, as now they can move onto the frontiers of land, where civilization will soon be born. Bear in mind of course, that these later stages are raw prototypes and are not indicative of the final rendition.

Prototypes going further than ever before.

Rich Backgrounds

Other Notable Changes

• The membrane generation algorithm is now massively faster, and only results in slightly visually different membranes.

• Added HUD messages that show to report various things to the player, for example if the player can't engulf something the reason is now shown with this kind of message
• Colony members that can engulf can now enter engulf mode even if the player cell cannot engulf
• All chemoreceptors in a cell colony now function instead of only the lead cell's chemoreceptors working
• The spawn algorithm for filling the area around the player now only spawns up to 80% of the entity limit to allow the sector spawning logic more chances to work

• Fixed a visible seam in cell wall textures that was caused by the membrane generation code
• Fixed a bug introduced in previous release where organelle tooltip process numbers did not react to patch change (photosynthetic organelles were the visible place where the issue was visible)
• Fixed new game menu not wrapping text which could cause long translations to push settings sliders offscreen
• Fixed the current resolution display in the options menu not always updating when toggling fullscreen mode
• Fixed popup window close buttons not having a visual style for the focused state, which caused it to appear like no GUI element was focused in a popup when the close button was focused
• Fixed the membrane disappearing for really thin and long cells
• Fixed engulfed tutorial appearing even when the player could not be ingested
• Fixed crashing when changing language after having visited the art gallery screen
• Fixed editor tab buttons being too wide and overlapping the light level bar
• Fixed temperature "compound" being incorrectly shown in the patch compound statistics graph
• Fixed uneven main menu buttons with long translation texts, all buttons now stretch to the same width when one translation doesn't fit

• Removed classic patch map option as it had bugs specific to it and it was not going to get anyone to maintain that code to be compatible with new features
• Reworked our custom popup window handling, organelle popup menu now has animations for opening and closing
• Microbe digestion code now only runs 30 times per second to use a bit less performance
• Removed saving of usefulCompounds in a compound bag as that data can be regenerated very easily and it increased save sizes unnecessarily
• Our input system now throws an exception when registering a duplicate listener object, this will help in developing the game by catching that mistake much sooner
• Improved the features of our GUI focus grab system
• Improved the usage and internal features of our custom tooltip system
• Refactored the species details panel and fossilization dialog internally to be more reusable

Warning: there's still an intermittent save loading and creation bug (see: https://github.com/Revolutionary-Games/Thrive/issues/4156)
• Updated Netanalyzers library version to 7.0.1
• Updated our used JSON library to version 13.0.3
• Updated YamlDotNet to 13.1.0
• Updated some check tool package dependencies
• Updated our code checking tools version
• Updated translations

Time for another pre-release testing of Thrive before 0.6.2 is released. The most major things you will see are the new 3D main menu backgrounds (these are a bit performance intensive), as well as the continued prototypes which are now all the way to the end of society stage. Theres also been a ton of small changes, fixes and graphics tweaks. To play the RC opt into the beta version of Thrive in the Steam client game properties (right click the game). You can share your feedback either in the comments here or on our forums: https://community.revolutionarygamesstudio.com/t/0-6-2-release-candidate-testing/6345 Well try to fix the most major found problems before the full 0.6.2 release next week.

Were back again with our latest tri-monthly release of Thrive! This update brings to you a long awaited feature; The further adaptation and specialization of otherwise familiar parts. That is to say, part upgrades are finally here! As of now, only one upgrade exists, which provides cilia with a brand new functionality for players to experiment with. This and more, will be elaborated upon further into the post. [previewyoutube=tpatXf9YkyE;full][/previewyoutube] Our developers have worked hard to bring you an expanded Thrive experience. Weve outlined the major changes in this devblog, but you can see the patch notes for a full list of features and bug fixes at the end of this post.

To test the version early switch to the "beta" version on Steam (in the game properties) and you can then play the test build.

The Steam version of the launcher has been updated to version 2.0.3, this brings in various bug fixes and small improvements over the previous launcher version. Luckily there weren't any critical issues with the huge 2.0 release of the launcher, which meant that we didn't have to put out multiple small bug fixes immediately after. The most visible change with this should be that the game launch failure detection advice should get displayed more reliably.

Today we are proud to present the final update within the year of 2022; Thrive 0.6.0! Twilight now falls on the seas of Thrive, and the normally dominant autotrophs now face their greatest enemy It is always darkest before dawn with the beautiful addition of the day/night cycle! Found a species you love and want to remember forever? Immortalize it with the all new fossilization tool included in the long awaited Thriveopedia, future home of all things informational. These and more, in Thrive 0.6.0! Specifically in the Steam version one of the most major things you'll see (or won't see) is that the Launcher will no longer be visible before Thrive is started. The launcher is still able to open automatically when there is a reportable crash or if you use the special button in the Thrive main menu to exit to the launcher. If you prefer, you can configure the launcher to be shown before starting Thrive to get back the old functionality. [previewyoutube=tko9CMr7Adk;full][/previewyoutube] Our developers have worked hard to bring you an expanded Thrive experience. Weve outlined the major changes in this devblog, but you can see the full patch notes at the end.

The Thriveopedia

Fossilization

Day and Night

Launcher 2.0

Other Notable Changes

• Thrive now has a new intro video when you start the game. Make sure you have it enabled in the settings so you can appreciate the exciting view!
• The main menu now features social media icons so that you can easily find a community outlet of your choice.
• Thrive now has a safe-mode triggered crashing, which disables all mods and video playing before restarting.
• Pili now feature a slight damage delay, preventing them from rapidly inflicting a large amount of damage at once.

Looking Ahead

Patch notes

• Added day/night cycle. Note that due to missing tutorials, balancing etc. which we didn't have time for, you need to manually enable this feature when starting a new game in the advanced options.
• Added the first few pages of the Thriveopedia to show info about the current game and show the evolutionary tree now in the game proper as well
• Added fossilisation feature to save selected species to the museum which can be loaded through the Thriveopedia to the freebuild editor
• Pilus damage now has a cooldown to prevent a ton of damage from it very quickly
• Balancing changes
• Fixed infinite compound ejection caused by negative compound ejection (only a bandaid fix for now due to time constraints)
• Engulfing now gives extra glucose on top of what the engulfed cell actually had
• Membrane colour transparency works again. Be prepared to have AI species evolve to be more transparent again to avoid being eaten by the player.
• Refactored our code related to species colour adjusting when used in graphs
• Fixed multiple issues related to organelle graphics rendering by changing their render modes and splitting organelles into transparent and opaque ones
• New intro video
• Added our social media and website links to the main menu
• Added safe mode start up after Thrive crashed before managing to start fully. Safe mode can disable all mods and video playing
• Digestion efficiency display in the editor now shows the separate values for each type of digestion to reduce player confusion regarding them
• Fixed panspermia being selectable with LAWK being on by default now
• Enabled word wrap for credits to fix some misaligned columns
• Saving being unavailable in some prototypes now has the warning about that shown correctly when manually making a save in the later editors
• New mucilage and slime jet icons
• Starting with no mods enabled but having installed mods now shows a heads up notifying that mods need to be enabled first before they work
• Fixed evolutionary tree being cutoff even when fully zoomed out
• Added some features used by Thrive Launcher 2.0. Added button to exit to the launcher when the launcher is hidden and would otherwise be difficult to return to from Thrive. Store versions of Thrive now use seamless launcher mode to not show the launcher window before starting Thrive.
• Improved performance of our custom rich text labels by only registering input listening when necessary
• Saving now uses a new Godot API to generate the screenshot PNG this avoids an unnecessary temporary file write to disk and should be faster as a result
• Fixed a rare crash when using a lot of slime jets
• Added a bandaid on infinite compound ejection due to engulfed object having compounds with NaN amounts in it
• Added some guards against dividing compound amounts by zero this should hopefully reduce how often the NaN compounds bug happens
• Changed scene change mod callback to trigger slightly earlier
• Updated some code comments related to the saving system
• Fixed localization update script writing BOMs in .po files on Windows
• Fixed some typos in the English text
• Updated translations

0.6.0 will be released next week and because of that we are putting out a test build of the new version. To play the test build switch to the "beta" version in the game properties in the Steam client. Note before you download that the day/night cycle needs to be turned on in advanced new game settings to work. All the other major features like Thriveopedia will work with existing saves in a limited manner. And please note that for now the new launcher 2.0 doesn't yet start in seamless mode on Windows (so you'll still see the launcher before playing Thrive). This will be fixed for the full 0.6.0 release. If you have any feedback please post it on the relevant thread on our forums at: https://community.revolutionarygamesstudio.com/t/0-6-0-release-candidate-testing-and-launcher-2-0-testing/5735 or in the comments below.

Today we are proud to announce the release of Thrive 0.5.10, which among a large host of bug and performance fixes, provides players with brand new tools to play with and study their world. Deter predators by impeding them with the sticky mucus left in your wake! Live your life to the fullest as a proper vegetative plant, without having to search for compounds! Create entire timelines to your exact specifications with the new autoevo tool! All of this and more, awaits you in the latest in Thrive. [previewyoutube=VrHI4_CrivQ;full][/previewyoutube] Our developers have tirelessly labored to bring you an expanded Thrive experience.

Auto-Evo Exploration Tool

Other Changes

• Auto-evo calculations have been updated to encourage sessility in AI species, and now runs 60% faster as well.
• LAWK (Life as We Know) is now toggled on by default when starting a new game. If you want to play with thermosynthesis, make sure to turn this setting off before starting!

A new release is soon here so it is time to do the customary pre-release testing. Some of the major features if you decide to test this will be the timed reproduction system, auto-evo exploring tool and various fixes and tweaks in a bunch of places. The release candidate can be accessed by switching to the "beta" branch for Thrive in the game properties on Steam. Feel free to provide feedback about any new issues you experience with the new version and we'll try to fix as many problems before the release as possible. You can leave feedback either in the comments here or on the dedicated feedback thread on our forums.

Thrive, just like the creatures it simulates, is constantly evolving and improving. But to do that, we need effective channels by which we can hear feedback from the community. We decided to make this process much more streamlined by introducing a new Suggestions Board for the game! It's easy to sign up, using either your email, Discord account, or Github account. Once logged in, you can:

• Submit suggestions
• Comment on other suggestions
• Vote for the suggestions you support
• Search for suggestions by tag, whether they're trending, the most wanted, the most discussed, and more

Three months since our last release, were back with another Thrive update. Thrive 0.5.9 heralds the arrival of a large slate of game-changing features, many of which have long been stuck on our to-do pile. From procedural patch maps to 3D editors, cilia to thermoplasts: read on to learn more about these new additions. Our developers have worked hard stuffing this release full of juicy new content to make the game a richer and more diverse experience. Weve outlined the major changes in this devblog. See the patch notes for a full list of features and bug fixes. [previewyoutube=3D3u88bSHSc;full][/previewyoutube] Note that saves created in previous releases will not load in Thrive 0.5.9. This was a necessary change for some of the new features to work correctly, since the new features were so big it wouldnt have been worth the large effort to write a save upgrader.

Procedural Patch Map

New Game Settings

Engulfment Revamp

Macroscopic Prototype

Cilia

Thermosynthesis

Spawn System Revamp

Art Gallery

Other Changes

• Easter eggs Weve added one type of randomly spawned Easter egg to the game environment, and most of you will find it quite familiar. Can you find it?
• Patch-wide population system Going extinct in only one patch no longer means game over. Instead, youll be greeted with a screen to choose a patch where other members of your species reside, giving you a second chance to thrive.
• Configurable maximum entities option If youre having performance problems, head to the options menu and reduce the maximum number of entities in the performance tab. While its not a silver bullet, this should go some way to helping those with less powerful machinery play the game.
• Pause hotkey Press space to pause and unpause the game.
• Debug overlay Press Ctrl-F3 to open the new debug panel, featuring performance metrics and other helpful information.
• Nucleus damage reduction Having a nucleus now gives a 50% reduction in damage caused by enemies.
• Many other tweaks and bug fixes!

Looking Ahead

0.5.9 is approaching so it is time to do the usual pre-release testing. Note that this time we expect to break save compatibility between the rc1 and 0.5.9 release. So either dont put too much time into saves with the RC or be mentally prepared to not be able to load them in 0.5.9. With that out of the way some of the most major things youll see are the engulfment revamp, procedural patch map, cilia, and continued work on the prototypes. Of course theres a bunch more other changes included as well. The release candidate can be accessed by switching to the "beta" branch for Thrive in the game properties on Steam. Feel free to provide feedback about any new issues you experience with the new version and we'll try to fix as many problems before 0.5.9 is released as possible. You can leave feedback either in the comments here or on the dedicated feedback thread on our forums.

This is a re-issued patch 0.5.8.1 as we noticed that the crash reporting system was not functioning correctly. This update only changes how the engine version was built compared to 0.5.8.1 in order to make the crash reporting system fully functional again.

0.5.8.1 is out now. This release focuses on performance improvements and other smaller fixes. Of special note is that the game should now work on Windows 7 through Steam thanks to us switching the library we use for interacting with Steam. Also we have added inbuilt support for Harmony based mods for this release. There are 2 new example mods from us on the workshop showing off this feature. They are cell autopilot for letting the AI take control of moving your cell and random part challenge which is a challenge where you are given one random organelle per editor cycle and you need to try to survive. Patch notes for this release:

• Fixed major problem with the spawn system not being able to despawn things as fast as it spawned. This should give a major improvement to later game performance
• Improved game object processing speed and added some multithreaded processing to them
• Fixed crashing in text formatting when using our localized text class to guard against bad translations
• Fixed incorrect translation bbcode being able to crash the game
• Updated to Godot 3.4.4
• Switched to a different Steam client library to make the Steam build work on Windows 7
• New mod loader improvements to have inbuilt Harmony support
• Fixed enemy spawn cheat not making the spawned cells despawn
• Fixed auto-evo using energy balance instead of consumption when calculating populations
• Reduced flagellum energy cost to 4
• Fixed unintended cannibalism when player becomes multicellular
• Fixed an issue with the player species not spawning in multicellular
• Fixed dead cells being able to be added to a colony causing issues
• Fixed bacteria group spawns spawning things that immediately despawn
• Added a new more detailed metrics panel (default key is shift+F3) to be able to see game performance in more detail
• Microbe editor now shows the total storage of a cell
• Added a new microbe stage ambiance track
• The options menu now shows the resolution the game renders at
• Main menu music now fades out when starting a new game instead of cutting out immediately
• Fixed patch map nodes reacting to the scroll wheel
• Partially fixed NaN compound storage amounts by resetting them to 0
• Fixed incorrect "{0}" shown in save upgrade fail message
• Fixed our custom colour picker leaking Godot objects
• Simplified logic slightly in name permutation generation
• Romanian language is now available in the game
• Updated translations

Thrive version 0.5.8 is finally here; And with it comes the versatile signaling agents, which allow you to actively communicate with your allied cells; New randomly generated region names, which gives each world a new and unique flair; The highly anticipated multicellular prototype, which permits you to progress further than ever in the grand journey of Thrive; And of course, a grand host of other changes and bug-fixes! [previewyoutube=7ygUoOw5kJo;full][/previewyoutube] If you want a summary of what this version brings, here are the full patch notes for this release.

The Multicellular Stage Prototype

New Signaling Agents Part

Misc. changes

• Colony members now affect how fast a colony can move, their mass now has a slowing effect but their flagella will help the colony move
• Increased compound cloud brightness in brighter biomes to make them much easier to see
• AI now knows how to use the chemoreceptor
• Generated membranes are now cached to reduce lag spikes also slightly made the membrane generation algorithm faster as well
• Cell corpse chunks are now added to be counted in entity limit which seems to help a bit with performance
• Increased entity limit considering the recent performance improvements. Its also no longer save file specific so older saves will also use the new limit now
• Taking damage due to being out of ATP now has a specific sound for it
• Auto-evo now takes environmental compound availability into account when calculating fitness
• Balance tweaks, includes adjustments to organelle costs
• AI will now stop moving if it is out of ATP and wait to recharge
• Brought back the accidentally deleted win screen background
• Binding mode sound now fades in and out better
• Chemoreceptor colour is now automatically selected to match the compound colour in the modify GUI
• Extinction music now starts earlier to sync up more dramatically with the appearing extinction text
• Tweaked the wording of most of the tutorials
• Made the tutorial highlight background darker to make tutorials pointing to GUI elements more obvious
• Added a command line flag (to be used with a new launcher version) that disables all videos as one player had a problem with the intro video crashing their game
• Disabled the X button on the organelle modify popup as that seemed a bit too error-prone to a player
• Saving will now detect if the save name is too long or invalid and give an error instead of silently failing to write the save to disk
• Charts will no longer show x or y incorrectly when they werent supposed to
• Added some code to the binding process that tries to detect disposed cells earlier, hopefully improves sometimes buggy binding
• Implemented custom logic to workaround Godot colour picker pick from game window having a (potentially crashing) bug
• Improved theming for file dialog
• Removed duplicate phosphate icon file
• Disabled resizing the editor report tab panels as that could break the text layout
• Translations now use no line wrapping, this time unnecessary changes caused by that with Weblate disagreeing with gettext seem to be finally fixed

Whats next?

0.5.8 is releasing next week. A release candidate is now available to test the new release early. It can be accessed by switching to the "beta" branch for Thrive in the game properties on Steam. Feel free to provide feedback about any new issues you experience with the new version and we'll try to fix as many problems before 0.5.8 is released as possible.

This week weve finally produced a first playable version of the multicellular prototype which currently features cell type specialization and gameplay. This is a monumental step in Thrives development, but there are yet many more steps on the long road of progress that await us. This prototype will be packaged with the 0.5.8 update, which also includes the new signaling agents part and a large host of other changes. 0.5.8 is currently scheduled to release later this month. Development progress this week:

• Chemoreceptor colour is now automatically selected to match the compound colour in the modify GUI
• Early multicellular prototype, which is very rough currently
• Updated translations

• Added new signaling agent organelle
• Increased compound cloud brightness in brighter biomes to make them much easier to see
• Tweaked the wording of most of the tutorials
• Switched chemoreceptor to use a different algorithm based on rays around the cell to find compound positions
• AI now knows how to use the chemoreceptor to find compounds
• Added some code to the binding process that tries to detect disposed cells earlier, hopefully improves sometimes buggy binding

Today we have released version 0.5.7 of Thrive which includes a new cell part for players to play and experiment with, and an expanded report tab in the editor. Players will never need to worry about not finding what they are looking for, because by evolving the new chemoreceptor part, cells will be able to sniff out resources from considerable distances! Suddenly realized a species is missing and want to know when they went extinct? The history of your world is now chronicled in the newest feature of the report screen; The timeline tab. Alongside these new features are a host of various bugfixes and optimization to ensure that everyone can properly enjoy Thrive at its fullest. We hope that everyone enjoys this release of Thrive as much as we enjoyed making it, and are looking forward to hearing what everyone thinks. Note that if you are upgrading an old save game to this latest version, the player cell needs to first die and respawn before the chemoreceptor functions properly. Patch notes for this release:

• Added chemoreceptor organelle which shows lines towards detected compounds. Note: old saves are compatible but the chemoreceptor won't work until you die and respawn if you loaded an older save.
• Implemented the organelle modify menu. For now only used for the chemoreceptor
• Implemented the timeline tab in the editor showing world or patch related events that have happened in the game world
• Updated to Godot 3.4.2. We are using a custom Godot build as our Breakpad code was not merged yet.
• Reduced max entity count a lot again. This should make it so that extremely low performance of the game doesn't happen anymore. We are still investigating the performance issues and will increase the game entity counts again once we have addressed the part of the game that is actually too slow.
• Added a crash dumping system back to the game. Combined with the latest launcher version this allows reporting the crashes to us developers to view on ThriveDevCenter Note that the crash reporting is not implemented for mac, yet.
• Fixed the choppy intro video playback in the previous release caused by Godot removing optimized webm playback on Windows
• Fixed flagella animations not working after update to Godot 3.4
• The report tab of the editor now has a patch selector drop down that allows changing patches on that screen to easily view the graphs for other patches
• Player species is now always printed first in auto-evo results and other species are in alphabetical order
• Added a button on graphs to show the graph in bigger size to more easily see what the graph shows
• Adjusted microbe movement sound
• Added a separate ice damage sound instead of using the general damage sound for them
• Double clicking a save now loads it or asks to overwrite it if double clicked in the create save menu
• A few more tutorials are now forced (the close button for them has been disabled)
• Cell speed calculation has been improved regarding flagella that don't point backwards. Now speed is calculated along the direction the player's cell can move the fastest in, which is not necessarily forwards.
• Movement ATP drain was also updated with the above change, and now it also only considers flagella that can push in the maximum movement force direction. So no longer do forward facing flagella show up in editor as costing ATP when in fact they can't operate at the same time as backwards facing flagella.
• Added scientific flavour text for the pilus
• Disabled multithreaded rendering option which seemed to cause rare issues while not helping at all in normal use
• Improved look and tooltip positioning for the editor sliders
• Added a sound effect for when cells collide hard enough
• Increased the fade duration when changing music tracks
• Remade the trash icon as higher resolution and added a pressed state for the trash buttons
• Graphs now group extinct species separately
• Tweaked the visuals of the toxin particle effect
• Tweaked the patch name display fade animation
• Reduced small iron chunk mass so that they are easier to push around than the big chunks
• Fixed external effects on extinct species causing errors
• Fixed graphs using 32-bit integers to hold data, which caused the graphs to not display correctly when species populations got too high
• Fixed tutorial boxes being on top of the pause menu in terms of mouse clicks
• Fixed dialog resizing sometimes expanding them in the wrong direction
• Fixed pause menu, win and lose screens not resizing when the game window is resized
• Fixed a bug in our hybrid 3D audio player class not actually behaving spatially
• Fixed the widths of a few organelle tooltip titles
• Fixed refresh button in mod manager sometimes causing duplicate mod entries to appear
• Fixed really long save names causing GUI layout problems by enabling text wrapping for them
• Fixed pressing ESC in the game over load menu not closing the right thing
• Fixed folders ending in ".thrivesave" being detected as save files and causing problems
• Fixed the randomize species name button not being the same height as the text box it was next to
• Fixed some scenes (that are intended to be used like this) not being able to be started directly from the Godot editor due to resource loading order
• Disabled mouse wheel scroll on colour picker bars as they are usually within a scroll container causing issues depending on mouse positioning when scrolling
• Auto-evo prediction runs are now cancelled earlier to try to avoid error prints regarding them failing due to the player editing their species again before the run finished
• Reduced the volume of microbe-theme-7 to be more inline with other music
• Slight source code cleanup by moving the food source classes to the namespace they should have been in
• Updated our CI checking tools
• Improvements to our build scripts
• Updated translations

Release candidate for 0.5.7 has been released. 0.5.7 will be released in one week so we are releasing a test build now. You can play the test build by selecting the beta version of the game on Steam. We are releasing this test build to catch the most glaring errors before 0.5.7 is released. If you find any new bugs or new features that aren't working please let us know, either in the comments or on our forums in this thread. If you experience any crashes the launcher should give you the option to report them to us, if it does please send us your reports. If there aren't showstopper bugs that we can't fix in time, 0.5.7 will release in one week. The major new features are the new crash reporting system, timeline tab and other editor GUI improvements, as well as some adjustments to address low performance.

This week we have focused on further performance improvements for the game, and the upcoming chemoreceptor part. The chemoreceptor will act as a radar ability for your cell, pointing the way towards food that would otherwise be just out of sight. In the future, this part may become customizable to allow for targeting specific foodstuffs, or perhaps even detecting allied or unrelated cells! In later stages, this will be an important part for specialized olfactory cells on your organism. As for optimization; our investigations into the cause behind late game lag is still on-going, but we hope to resolve the issue as soon as we can. For now we are going to further limit the number of game entities that are allowed to spawn at once. With the already finished work and soon to be finished work, we have started thinking about when to release 0.5.7 to bring these updates to everyone. Right now we are planning to have 0.5.7 released within a month, maybe as soon as in three weeks. The crash reporting system that will be included in the release is already mostly done and only needs some tweaking to make sure it works on Windows. We also need to make a custom version of Godot engine for this as our PR to them has not been accepted yet. The other changes this week:

• The editor report screen now allows changing the patch on it to quickly view graphs for the other patches
• Fixed flagella positioned in a specific way messing with an accurate speed reading, now its defined as the speed in the direction the cell can move the fastest in (which is not necessarily forward)
• Added a separate sound for ice damage
• Microbe movement now has a continuous low volume sound that plays after the movement start sound
• Remade the save delete icon in higher resolution and added a pressed down state for the button
• Lowered volume of microbe theme 7
• Updated translations

• Added a button on graphs to open a bigger view of them to see the data more clearly
• Fixed flagellum animation not working in the previous release (was likely caused by the Godot 3.4 upgrade)
• Converted videos to theora format to fix the stuttery playback on Windows in the previous release (also caused by Godot 3.4 which removed vp8 optimized playback on Windows)
• Player species is now always first in auto-evo results and other species are in alphabetical order
• Disabled multithreaded rendering that didnt seem to help and perhaps caused some reported issues

For this patch we tried to address the most reported issues regarding auto-evo taking too long and being too punishing. Various other fixes and improvements also got done while those other things were being worked on. Full patch notes:

• Added a panel showing auto-evo prediction raw numbers to help players understand how auto-evo sees their species
• Various changes hoping to improve auto-evo experience: fixed iron not being taken into account, fixed marine snow density not being taken into account, added extinction if too many species present in a patch, greatly improved auto-evo speed (about 20x faster now)
• Pili in colony members now function correctly
• Reduced max game entities to 300 to reduce late game lag
• Excess compounds from engulfed chunks are now released as clouds
• Removed the X close button in the undo button tutorial as people were too happily skipping it
• Updated to Godot 3.4
• Fixed flagella pointing direction being sometimes broken, especially when at 0,0 coordinates
• Fixed auto evo using energy balance instead of total consumption in a few calculations
• Empty saves list now shows a text saying no saves exist
• Tweaked engulfing sound, it now fades in and out
• Fixed binding agents organelle duplicating when preparing for reproduction, now the code uses the organelle unique property to detect which ones should not be duplicated to be future-proof
• Changing maximum FPS is now possible in the options
• Fixed a disposed microbe bind by running the attach callback on the next frame, like it was supposed to run as per old code comments
• Detached colony cells now keep their rotation that they had in the colony
• Changed the auto-evo prediction tutorial to mention the new prediction panel that can be opened to show all the numbers for it
• Added validation to save names (and stricter species name validation) to ensure saving doesn't fail due to file writing issues when filenames contain invalid characters
• Added a global lock around save image resizing when loading for display, this seems to help around a Godot multithreading issue that caused / causes crashes when opening the load menu
• Fixed bugs regarding the binding agent sometimes being the wrong colour
• Fixed problems with colour picker texts being able to be too wide
• Fixed old Godot version being mentioned in our documentation
• New mod form now requires internal name to start with a capital letter
• Added documentation regarding profiling the game
• Updated our styleguide and git usage guide
• Auto-evo results now react to language change
• Fixed auto-evo prediction texts not updating on language change
• Warning popup on trying to open a non-existent directory should now work on Windows
• Dehydrated builds now ignore some file types, which should result in less dehydrated downloads per devbuild, thanks to a new godotpcktool version that supports name filtering
• Full mod info now includes internal name
• Various modding improvements: forgetting uploaded Workshop mod details, manually entering an existing ID, mods can specify if they require a restart, mod uploader now allows entering change notes and it now warns if preview image is too large, the uploader also now remembers the details that were last used to send an update, tweaked mod manager layout
• Mod manager scene can now directly be launched from Godot for debugging
• Enabled autowrap on mod load caveat text to ensure it doesn't go offscreen in some languages
• Switched to using NetAnalyzers package instead of the deprecated one we used before
• Updated translations

This hotfix contains efficiency improvements to the auto-evo algorithm which should make it roughly 20 times faster to keep even later game waiting times more reasonable. After investigation the exit code 3221225781 turns out to be a missing DLL error. We have added automatically shown advice about this problem in the launcher. The issue seems to stem from using an older version of Windows (only Windows 10 is supported) or not having latest updates for Windows 10 Universal C Runtime. The beta branch will contain a build that may work better for older Windows. This build also includes a few unrelated changes that happened to get done: auto-evo prediction text now changes when language changes, and mod manager caveat text is now auto-wrapped for translations that wouldn't fit on screen otherwise.

This month marks a major turning point in our history as for the first time, Thrive makes its official debut in stores! We are proud to announce that Thrive is now available for purchase on Steam for those who wish to support Thrives further development. For this release, we held a major focus on overall quality and bugfixes for Thrive, which ultimately resulted in a substantial improvement to stability and performance that will ensure a smoother experience than ever before. Even still; We also managed to squeeze in a few defining features that sufficiently expand the depth of functionality such as the long awaited behavior editor enabling customization of allied cells actions, the ever promising mod loader that is sure to inspire customization beyond the games convention, and an expanded auto evo system that now even include the players population. We hope that you enjoy playing with this update as much as we did making it! You can read the full, more in-depth details about the new features of 0.5.6 on our website.
