Write a First Person Game in 2KB with Rust
Nice writeup! Building raycasting engines is fun and rewarding. You can get a lot of visual impact with very small and easy to understand code. I took a stab at it and ended up adding portals which I thought was really fun (https://github.com/gh123man/Portal-Raycaster).
I've been thinking about re-writing my raycasting engine in Rust but never really found the time - glad to see someone has done it and documented it so well!
If anyone else is interested in raycasting this page is also worth a read: https://lodev.org/cgtutor/raycasting.html

Rustenstein 3D: Game programming like it's 1992
Ray casting is close to my heart as it's easy to understand and has a very high "effort to reward" ratio, especially to someone who is new to graphics programming. I built a game + engine around ray casting portals [1] (think the game Portal). It was a lot of fun trying to figure out how to bounce rays around a scene and intersect with different objects in the environment and immensely satisfying to have built the whole engine from the ground up. Though I'd probably not do it again. Your top-down ray debug view is very similar to one I came up with!
Some of the interesting bits of the engine are open source: https://github.com/gh123man/Portal-Raycaster

Raycasting in JavaScript and React
If you find this sort of thing interesting, I implemented a "Portal" raycasting engine akin to Valves portal game. You can read more about how it works here: https://github.com/gh123man/Portal-Raycaster
