A clone of the game "Snakebird" programmed from scratch including software rendering. I also made a perspecive correct triangle software rasterizer.
- Live c++ code editing
- program is split into a platform layer (main) and a game layer (.so). The game code can be recompiled and dynamically loaded while the platform layer is running.
- Makes iteration on logic and graphical effects really seamless.
- Program recording
- program records game state every so often and saves all your inputs into a circular buffer.
- Playback since last memory save can be looped by pressing p
- This coupled with live code editing creates incredible possibility for live game logic or graphical debugging. After spotting a bug during runtime you can hit p and the game will loop, then you can edit the code live.
- Tile editor based DCC
- The game has 2 in game editors. One for gameplay logic and one for layerd graphical tiles.
- Essential snakebird gameplay features
- This clone has most features found in the puzzle game Snakebird, up to and including teleportation.
- Overworld
- The game has a level selection screen (here called overworld)
- New levels can be created by junping into the editor and saved by pressing ctrl+s
- The cube in the background is software rasterized
The project also includes a triangle rasterizer with perspective correct texture mapping (right image)
- The rasterization code is from Fabian “ryg” Giesen's blog
- Perspective correct texture mapping learned from an article by Chris Hecker on the topic
