hi guys, i am new with pure data and so facinated with the things one can do with it. i believe this forum can assist me to knowing more about this pd. right now, i am trying my hands on gem. i have created two circle or balls on a gem window and i have made them bounce of the wall at random. now, i want to programe it in such a way that the ball can rebounce wen they hit each other and not pass through each other. please can someone tell me how to go about it. thanks.

i used the bouncer object. the balls however move in the same direction on the x and y axis i want to change thier direction also. please help. hope to meet you online.
