How to make a simple 3d game (Raycaster) in Scratch. This is part 2 of a short tutorial and we actually create the raycaster. We'll cover projectiles, light rays, Godrays, Wide beam torches with shadows, 3d projection, lens correction, and two colour wall surfaces. I hope you are ready for some serious fun!
