Performance improvements

Switched renderer to OpenGL

Technical blahblah: Renderer was previously using DX11 (Windows) or Vulkan (Linux). Switching to OpenGL allows for a nice performance boost (especially on weaker hardware) while extending compatibility. Users with weaker hardware should experience general smoothness improvement, as well as faster grid generation. Users with more performant hardware should experience faster grid generation.

Removed Fluent theme and set Universal theme as default and only

Technical blahblah: Managing multiple styles that are so different is hard. It makes the code more complicated than it needs to be. So one had to go out. Universal is way lighter in resources and provides better contrast in both light and dark mode. It also provides a way to force color scheme (dark/light) on Linux, which was not natively supported before. I find it more suited to reflect Retr0Mine visual identity in general. Since it is easier to work with only one style in mind, Universal had a nice visual uplift (UI/Animations).

Misc

• Fixed inverted client flag colors in multiplayer
• Reworked signal indicator
• Revert multithreaded board generation (implementation is faulty, needs investigating)

Retr0Mine: Co-op Mode Update (BETA)

Solve grids together with a friend! Retr0Mine now features a cooperative mode where two players can tackle puzzles together in real-time.

How to Play Co-op:

As the Host:

[olist]

Select your desired difficulty and grid size before starting the session

Navigate to Menu -> Coop (beta)

Click "Host" to create a new session

Invite a friend from your friend list

Once your friend joins and their game syncs with yours, the Start button will become available [/olist]

As the Client:

[olist]

Accept the invitation from your host

Wait for your game to sync with the host's settings

Get ready to solve puzzles together! [/olist]

Features:

• Real-time synchronization of all actions between both players
• Shared grid progress and status updates
• Either player can contribute to solving the puzzle

Current Limitations (Beta):

• Question marks / safe question marks not available
• Hint request disabled
• Unable to change difficulty once a session has started

Permanent Limitations:

• No timer functionality
• No leaderboard saving
• Save/load feature disabled

Both players can end the co-op session at any time by returning to the Coop popup and clicking "Cancel". This co-op mode is currently in beta and will be improved with future updates, Expect some bugs. Have fun!

• Added new algorithm (Avoid 5050)
• Fixed a lot of ui freezes (when generating a grid, when launching Retr0Mine, when changing difficulty)
• Added a loading screen (progress bar correspond to generated cells - total cells)
• Added a game generation loading screen (progress bar correspond to placed mines - total mines)
• Added rules popup in menu
• Added confirmation to clear leaderboard (second press on the clear button)

Note: since the new algorithm has to do more work to place mines in a winnable configuration, grid generation can take longer (hence the new generation loading screen)

[ 2025-03-01 18:45:15 CET ] [ Original post ]

• Added dim intensity slider in visuals settings
• Added hide timer switch in visuals settings
• Added first click protection switch in gameplay settings
• Reorganized and edit settings ui for better clarity
• Performance improvements

First click protection was already the default behavior for Retr0Mine, now you can disable it if you prefer.

[ 2025-02-26 11:52:46 CET ] [ Original post ]
