A basic raycast example using the Pyxel retro game engine. The project started as an experiment porting the OneLoneCoder CommandLineFPS (see video tutorial here) to Python and Pyxel, but went a bit farther with some dithering and camera control (including "vertical" looking).
A resolution of 240x136 and framerate of a whopping 30fps was achieved using two techniques:
- Interleave rendering (alternate drawing even and odd columns)
- Using one of Pyxel's image banks as a display buffer so the scene can be rendered with a single draw command
Some additional tips, specifically "vertical" look, can be found in this article.
- Python 3.7+
