Hi.

Was hoping there was anyone here that is familiar with using turtle in python.

Need help getting multiple balls to bounce off the edge of screen and having them collide with each other.

I have my starting code that I was able to do by myself.

PM me if this is something you can help with. Thanks

To get a circle turtle to collide with another, just do a check of: (t1, t2 are turtles)

Code

if t1.distance(t2) < collision_distance:
repel them or do whatever you need here

How about setting up the width/length to make sure the ball stays inside the screen

Use

Code

window_width()

and

Code

window_height()

methods on the Screen to obtain the width and height of your screen. Then you can just check if the turtle stays inside by:

Code

-width < x < width and -height < y < height

Where x and y are the turtle's current or new position after making a move. If it's the latter, you reset the turtle's position since it would be invalid.
