All your additions are clear, but it seems like whenever two balls collide, more than one ball is added to the arraylist and painted. Any way to have just one ball added to the panel for every collision? Have some kind of a toggle flag in paintcomponent? Regards Re: Bouncing Balls: Creating a new ball when two balls collide 2 Weeks Ago by jprog1000 Thank you so much for your reply and additions! It is certainly working as I wanted. I will read through the code you have added and ask you any questions I might have. I hope you don't mind. Regards Re: Bouncing Balls: Creating a new ball when two balls collide 2 Weeks Ago by Dani I’ll mark this question solved :) Re: Bouncing Balls: Creating a new ball when two balls collide 2 Weeks Ago by Dani … oh, sorry, missed the bit about you still needing clarifications. Feel feee to ask :) I’ll now unmark this topic as solved. /facepalm Re: Bouncing Balls: Creating a new ball when two balls collide 2 Weeks Ago by toneewa Yes, this is true. Overlapping ball spawns can do that causing a chain reaction. Something like that could be done. How you handle the spawning of the new ball is what I played with a bit before. You will see better collision detection changing to: g.fillOval(ball.getX(), ball.getY(), 1 * ball.getRadius(), 1 * ball.getRadius()); Re: Bouncing Balls: Creating a new ball when two balls collide 1 Week Ago by jprog1000 Got it. Thank you so much! Re: Bouncing Balls: Creating a new ball when two balls collide 1 Week Ago by jprog1000 Great reply, vortex! Agree with all your points.
