Merged the car and dungeon generator scripts, as well as implementing collisions, and tuning the car so it is more natural to use in the tight space. I tried to remove the possibility of getting stuck as much as I could, but there are still some scenarios that can lead to the collision acting up. Next I decided that i wanted to implement a weapon, so I added a minigun. Fun. (for a fun surprise, try standing still and shooting in all directions. Isn't polishing fun at an early stage? Hehe.) Uses DDA and circle ray intersection algorithms for bullets. If it doesn't hit an enemy, it uses DDA to determine the closest hit point so we can spawn a hit dirt splash thingy. Temporary art for that. I also added a basic enemy system. They don't have an AI, but they are still killable. Still needs art and AI though. Probably going to need some sort of pathfinding to avoid getting stuck or being stupid in the winding dungeons. Maybe A star? Hmmm...
