This is my attempt to create collision system. For now (and the rest of its existence) I'm using Continuous Collision Detection. I code it entirely myself as a challange, inspired by this video.
I know this program is not well optimized, and it really wasn't supposed to be. I build this on top of my first project (contact) with SFML as one of many different ideas to implement. There is a bunch of unused or unnecessary code.
I'm planning (and probably currently working on) to make a new, better and much more complex simulation than this one.
Again, it is nothing special.
