Okay... So this is my first *good* test at a raycaster, so I decided to share it. It obviously isn't very good, which is why I am going to be working on making a better one. However, it does draw the walls in a way I like. It is mainly map storage and movement handling that needs work - as well as added textures. :P
I might have used something from someone else, but I truthfully can't remember. I guess I originally learned *some* of the trig from the wiki, but I could probably figure it out on my own now. :P
