Bouncing Balls: Creating a new ball when two balls collide 3 Weeks Ago by jprog1000 Hello, I have a program which creates multiple balls and bounces them off when they collide. This works fine. import java.awt.Rectangle; public class Ball{ private int x = 0; private int y = 0; private int radius; private int panelwidth = 500; private int panelheight = 500… Re: Bouncing Balls: Creating a new ball when two balls collide 3 Weeks Ago by toneewa Some minor syntax fixes. Some things to consider are the collision and distance of drawing the next ball. A ball inside a ball's radius will cause numerous collisions. Even the starting ball locations can be already causing collisions. I added a collision counter display. Increased the maximum balls to make to 50. The timer delay can also impact … Re: Bouncing Balls: Creating a new ball when two balls collide 3 Weeks Ago by toneewa I cleaned up the code some more. Removed some things that were not being used. I ran into a couple problems which caused the freeze you mentioned. It was memory heap space and array allocating. E.g., if x or y becomes negative, and also infinite recursion. I added a x/y coordinate display for a ball, and tinkered with the placement of the … Re: Bouncing Balls: Creating a new ball when two balls collide 3 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 3 Weeks Ago by Dani I’ll mark this question solved :) Re: Bouncing Balls: Creating a new ball when two balls collide 3 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 jprog1000 Hello, Thank you again so much! 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 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 vortex_1 In my opinion, implementing a feature in a bouncing balls simulation where a new ball is created when two balls collide can add an interesting and dynamic element to the simulation. This feature can introduce a sense of complexity and unpredictability, making the simulation more engaging and challenging for users. It could also provide an … Re: Bouncing Balls: Creating a new ball when two balls collide 1 Week Ago by jprog1000 Great reply, vortex! Agree with all your points.
