Rustcaster

Pseudo-3D raycaster implementation in Rust without any graphics API.

(I only use OpenGL/HtmlCanvas for rendering the final image to the screen)

You can try it out here.

🤨 But Why?

Just for fun and learning. 🙂

🖥 Run on desktop

$ cargo run
// OR
$ cargo run --release

🌐 Run on web

$ npm run build
$ npm run serve
// Then navigate to http://localhost:8080/

🕹 Controls

• Move: W, S,
• Loook: A, D
• Strafe: Q, E
• Open door: SPACE (when close enough, a bit buggy though 😅)

📝 Plans

• Refactor the raycasting code (it's a bit messy)
• Add proper texture support (32x32 sRBG pngs or a similar format, TextureAtlas?)
• Implement billboard sprites (https://www.youtube.com/watch?v=w0Bm4IA-Ii8)
• Restructure the code to be a bit better, clean up main.rs messy OpenGL code.
• Maybe add a gun and shooting enemies?
• TODOs and FIXMEs
• GBA port? 😅 (gba crate, agb crate)
