==DOUBLE CLICK START== DRAG BLUE BALL AND CLICK SPACE TO MAKE THE BALL MOVE CLICK START FOR EVERY NEW POSITION USE ARROW KEYS TO TURN CUE This is are very realistic ball bounce physics. The way it works is that it depends on the speed (or force) amount, and the angle, and it will then calculate how much to bounce off, and in which direction. If the speed is too slow, then the ball might not even hit the other ball at all.
This type of bounce ball physics can be used in games like snooker or pool. You are free to remix this at any time, but please remember to put my name somewhere in your credits! :)
