i have a question to this :) to prevent the balls from sticking together you got the while loop with boolean altered right? i had to speed up the cueball to get this while loop infinite, so greenfoot stands still then, but thats very hard in your game, i did the same with the altered loop at my game, but my greenfoot stops much more often, any tips or solution i can get from you? ;) would be nice

is this the tutorial you got the collision results from? http://sinepost.wordpress.com/2012/09/05/making-your-balls-bounce/ cause mine does not work as fine as yours
