What is it you are trying to achieve? Now that I know how to do circle collision, is there a giant physics formula dictating the angles the circles bounce off of each other? I havent learned this in math, but i would like to know the relationships of angle, velocities, spin, etc. have on collision. |

For the most part it's really just about calculating the normals, and mirroring the velocities on the normals. (for a circle this is that line that connects the two centers of the cicle) Of course I'm not too sure about collisions, I just normally bounce the angles off in the above way, it may not be 100% accurate although it seems to work. I can't tell you anything about spin, that I am clueless on. |

Adding in spin requires adding friction and stuff, and takes pretty advanced physics. I'd not try it unless you're really comfortable with vectors and stuff. Otherwise, just calculate the normal. |
