I made one of the actors grow with change size and can't figure out how to make it stop at a specific width and height.Can anyone help?
Wrap the change size behaviour in a rule that says . . .
When the actor's width is less than 200 (or whatever you want) then . . .
So the as long as the actor is less than 200 wide the change size will trigger, as soon as the actor gets to 200 pixels wide the condition is no longer met so the change size will stop.
