   Calculating colliding balls angles??
  I am simulating two balls colliding, but having problems with calculating the new angle of the balls once they collide, is there a formula or some other way to do it?thanks.   
  If you already have some knowledge of Physics, this article will be helpful:http://www.gamasutra.com/features/20000516/lander_01.htm (you need free registration to view it).Otherwise, there are a buncha buncha articles about this in the gamedev article archives and also on google.   ;  If you are working in 3 dimensions you might want to consider a ready-made Physics engine like Open Dynamics Engine.
