Use the arrow keys to move. Up/Down is forward/backward. Left/Right is turn. This is a fast raycaster based on the code of my previous one. The rendering time has gone down from 500 seconds to 5 on average! Major changes for more optimization: - Rendering is wireframe. - The room is rendered in much larger (and less detailed) chunks - Better distance coloring Soon to support: - Collision detection - More speed - 3D sprites I'm so close to making this realtime speed...I just need some sort of new optimization and I'll be there :D
