Where can I see the source code?
It's not open source, but the first iteration of the engine was closely based on https://lodev.org/cgtutor/raycasting.html
Thanks, that's enough. I am just making my own engine for these articles. I saw that the game was similar to what I was getting, and wanted to know if you are actually using ray casting, or if you simulate it using 3D and a fixed camera.
