I get the sense this is very easy, but I haven't been able to make it work yet.
When I click a button, a ball is sent out on the screen and starts moving randomly. I want to press a button and have every ball on stage do something, like all get twice as large, or all turn white or something. I assume I'm going to capture a MouseEvent.CLICK on the stage, which then targets all the balls I've dynamically created, and then each ball can respond accordingly. But I'm stuck. Any thoughts?
