Hi all,
I thought I would post the results of my research into effective circle to circle collisions and reactions.
All of the ball in the following file have a mass assigned based on their radius, and this is used to calculate accurate angles of deflection as well as real-world momentum transfer. Could be used for a billiards type game engine since it sticks to the real world physics pretty well.
The overlap code was inspired by Bit-101s work, the rest is my own.

As always, the fla is available if you want to look under the hood.
