InDev 19 Change Log

Roads
There are now 5 tiers of roads, you can now build roads starting from tier 1 all the way up to 5. For example, if you wanted a tier 2 road, you'd first have to create a tier 1 road and build a tier 2 road on top. The roads will be built and maintained by new workers from a new building.

• Tier 1: Basic path. Villagers will automatically generate a basic paths in the ground in high traffic areas, offering a minor speed boost. The paths can also be built manually, for no resource cost, and function as the foundation to build roads on.
  
• Tier 2: Wood path. Costs 1 log resource per tile.
  
• Tier 3: Cobble and wood path. Costs 1 rock resource per tile.
  
• Tier 4: Board and cobble road. Costs 1 board resource per tile.
  
• Tier 5: Board and cut stone road. Costs 1 stone resource per tile.
  
• Note that because you need to have the previous road built in order to build the next tier, bringing terrain from nothing to tier 5 actually costs 1 log, 1 plank, 1 rock and 1 stone per tile.
  
• All road types will decay over time, requiring basic maintenance. The more traffic a road gets, the faster it will decay.
  
• A new Way-Maker Shack has been added to build and maintain the roads. The workers will automatically repair the roads as they start to decay, and facilitate any new road construction you assign.
  
• You can assign road work (to either construct, upgrade or dismantle) on the left hand work tab under the harvesting assignment buttons.
  
• The map editor now has a full complement of buttons and tools for placing and erasing roads.
  

• New Mobs; The Stone and Wood Golems. They will defend your village to their death, and if their Golem Combobulator is powered, will be resurrected or repaired when not in combat.
  
• New buildings; The Stone Golem Combobulator and Wood Golem Combobulator. These buildings will take in essence and resources, converting them into energy to create, resurrect or repair Golems defending your village.
  

• Monsters now will not start spawning until day 2. Giving the player one free day to build in peace.
  
• Monsters can now spawn anywhere on the map that has adequate space, that is not in range of the village or blocked by topography.
  
• The monster's global spawn rate now never increases.
  
• The monsters can create their own small spawn points that will spawn monsters locally. Meaning that while the global spawn rate never increases the spawn points will generate their own monsters. As more spawn points are generated, more monsters will spawn on the map in those areas.
  

• Added a new "headless" mob. An extremely weak mob that attacks in large groups.
  
• All monsters are less hostile in the day time.
  
• Small Slimes can now spawn on their own.
  
• Slimes are less hostile overall.
  
• Slowed Fire Elementals down slightly.
  
• Added a breakaway chance for hostile monster behavior if it's no longer their ideal attack time.
  
• Fire Elementals spawns now start at day 5, instead of day 3.
  
• Specture spawns now start at day 8, instead of 5.
  
• Changed Fire Elemental's level range from 1 to 7 to 4 to 7
  

• Builders can now harvest crystals.
  
• Improved combat targeting, now mobs will target the nearest mob that isn't being attacked first, if none exist, it'll help other mobs. This helps reduce the frequency a group of mobs will focus on only one target at a time, rather than the entire group.
  
• Most harvesting and clearing work is now assigned based on the closest location to the villager, rather than at random.
  
• Optimized the path finding and search algorithms, generally speeding up several areas of the game, mainly the AI.
  
• Decreased hunger decay rate for villagers by 20%. (Meaning they'll need less food!)
  
• Mobs now have more intelligent object, resource and mob search selections, and will not path to nearby targets that they can see, but would require a very long path finding route to reach (Example: Other side of a low wall with a long path to get around).
  
• All harvested resource searching patterns now look for resources nearby, if none are found, they only check whats in range of the village. This prevents villagers from going on long hikes into unknown land to grab resources far out of reach.
  
• Rewrote how starvation search works, making it much more efficient.
  
• Builders now more intelligently decide when they need to harvest resources, preventing them from ignoring high priority buildings because the resources don't exist anywhere on the map, but others for lower priority buildings do.
  
• Villagers no longer repair abandoned buildings in range of the village.
  
• Monsters now focus on attacking buildings until they're attacked.
  
• Mobs now only wander to radiance pools within a pre-set distance.
  
• Completely removed the old AI Pack behavior system, and replaced it with a new more intelligent system.
  
• Increased the time between pregnancy and coitus that actions can happen again.
  
• Female villagers can now only have a maximum of three children in their lifetime. This is to prevent "runaway birth rates" late game, but still keep the same birth rates early game.
  
• Villagers now interrupt working villagers to chat much less frequently.
  
• Workers will now store refined resources in storage buildings correctly.
  
• Decreased the amount of food that can be stored in homes, but increased the amount that can be stored in farms and farm storage.
  

• Fixed a crash that would sometimes cause the villagers and other mobs from being told there is a mob in range to interact with, when there actually wasn't. This effected multiple branches of the AI, like chatting, finding a mate, or finding a pack leader.
  
• Fixed a bug that would prevent a mob from finding something directly at its feet, sometimes causing some search algorithms to run too frequently and slow down the game.
  
• Fixed a bug that would corrupt a mob's AI on load, causing the game to crash.
  
• Fixed a bug where deleting an already previously loaded profile and creating a new one in the same slot would clone the settings from the old profile.
  
• Fixed a bug where overlapping collision maps wouldn't merge.
  
• Fixed a bug in the path finding, search and range building algorithms that was causing erroneous data on initial load.
  
• Fixed a crash if you attempted to select a map in the world map while the reset world function was running.
  
• Fixed a bug causing monsters to ignore non-hostile buildings.
  
• Fixed a rare crash when a mob would try to walk to a 1x1 sized object that was only accessible by its corners.
  
• Fixed a very rare save corruption when a tower was destroyed, but its projectiles were still active on the map when the game was last saved.
  
• Fixed a bug that allowed farmers to plant and harvest farmland in paused buildings.
  
• Fixed a bug that would sometimes cause object and mob bounding boxes to not be properly update, causing the player to be able to click on off screen objects and mobs.
  
• Fixed a bug causing essence collectors and radiance pools to stop collecting any essence over an extended period of time.
  
• Fixed a save corruption bug when a mob's AI was trying to interact with a removed/destroyed object at the moment of saving.
  
• Fixed grab tool accuracy when dropping resources on small objects.
  
• Fixed a minor bug that could sometimes cause mob damage to be zero.
  
• Fixed a bug that could sometimes trigger a severe storm instantly.
  

• New Tower: The Bullet Tower. Uses the same ammo as the Sling Tower, but can shoot over walls. A good close-range fast firing, low damage tower.
  
• Bow Tower now requires a small amount of crystals to build. (Note: Builders can now harvest crystals)
  
• Build requirements for the Mining Facility has been reduced from 64 logs and rocks to 42.
  
• Farmland no longer completely dies (deletes itself) if it has been frozen or fried too long.
  
• Increased the max occupants of all homes.
  
• Increased Bow Tower damage from 10-20 to 20-30
  
• Heroes, Guards and Guard buildings have been completely removed from the game. (Note: Replaced by the new Golem system)
  
• Slightly increased tower missile accuracy.
  

• The debug menu (F3) is now a little prettier.
  
• Minimap rendering process changed slightly to make topography more visible.
  
• Increased transition fade speed moving from the main menu state to the play state, map editor state, etc.

• Increased tool tip pop up speed, font size and moved the tool tip location over to below the mouse.
  
• Added the resource requirement list on the object overlay when placing an object.
  
• Moved "Hold to unselect" message to the mouse.
  
• Corrected a typo in the "Overheat" tip.
  
• Added sparkles to the construction outlines.
  
• Added a "low energy" message to essence based buildings.
  
• When the game is paused, the GUI will now freeze in place rather than closing all the tabs.
  
• Buildings with multiple errors now align the warning text correctly.
  
• Added the game version to the top right of the GUI.
  

• New Map: Applemeadow.
  
• Cleaned up a lot of the mob movement cost code and velocity calculations
  
• Adjusted mob tile positioning so their feet is center of a tile rather than their body.
  
• The maps have been converted from a 8 layer system to a 7 layer system. The game will automatically convert old maps to the new system.
  
• Rewrote all of the tile set movement costs, giving costs to many tile sets on the map, like flowers, foods, stumps.
  
• Resources on the ground now increase movement costs on that tile.
  
• Added shadows to cactus, flowers, crystals and all foods.
