Right now the script is:

if <touching [Edge] ?> then
turn cw (180) degrees
end

This is ok, but it makes the object turn around instead of bouncing correctly, and everything else I've tried makes it turn around at some point. I want it to bounce around the screen somewhat like the dvd logo. How can I do this?

In this case, couldn't the

if <touching [Edge] ?> then
turn cw (180) degrees
end

be switched for

if on edge, bounce

block?

An easy solution for a directional bounce is this:

forever
if <touching [ v] ?> then
point in direction ((direction) * (-1))
end
end

If you want a straight bounce you could do this:

forever
move (steps) steps
change [ steps] by (1)
if <touching [ v] ?> then
turn ccw (180) degrees
set [ steps] to [0]
end
end

You can customize it to make faster or slower movement.

This only works for verticle walls.
A horizontal wall with a direction of 91 would become -91, which still is on the wall.

Your right! I had made a pong game and was thinking of what I used for the paddle and ball bounce.

Actually, no. They do different things. The turn block sends it back to where it came from. The bounce block will make it change the direction by -1.

Yes, you are very right. However:
1) The topic is resolved.
2) The “if on edge bounce” is what @klobbo was looking for, and not the “turn 180 degrees” block.
