How to input angle of reflection

stacon0851 · **How to input angle of reflection -** 04-27-2012, 12:45 PM

Im making a brick breaker game and i need to know how i can get the ball to collide with the wall and bounce off at the angle of reflection and continue in the direction it bounced off. If anyone can help me with this problem it would be greatly appreciated.

Perhaps this pool game can help: http://www.alice.org/community/showt...highlight=pool

I went about this by making a ball switch directions if it got close enough to the edge of the screen.

Could you set it up as an equation where the ball moves away from the wall at outgoing angle == incoming anglex2 asSeenBy the wall?
