I got a solution to the problem. For anyone that cares I added
listeners to systemManager (after initialization) with capture as
true, then I check to make sure target.owns(this) then I set
visibility based on this function:
private function isVisible():Boolean {
var obj:DisplayObjectContainer = this;
while (obj != null) {
if (!obj.visible) {
return false;
}
obj = obj.parent;
}
return true;
}
I was hoping for a little prettier way to go, but this is manageable
and works.
Thanks for all the help guys.
