   Hey I wonder what happens if there's a TWEEN_COMPLETED handler scheduled to be called but before it gets
   called another tween schedules the handler to be called with a different target..what happens to the original handler?

   Hi Mike!

   I'm not quite sure if I understand your question correctly. Please correct me if I'm wrong: you've got a tween and add an event listener to its "onComplete" event:

   [tween1 addEventListener:@selector(onTweenCompleted:) atObject:self
                     forType:SP_EVENT_TYPE_TWEEN_COMPLETED];

   And then you've got another tween that uses the same method, but another target:

   [tween2 addEventListener:@selector(onTweenCompleted:) atObject:someOtherObject
                     forType:SP_EVENT_TYPE_TWEEN_COMPLETED];

   And then tween2 finishes before tween1 does.

   If this is what you mean: that should not be a problem. Internally, the event dispatcher (the tween) always saves the target (self, someOtherObject) together with the selector (onTweenCompleted:). They are not overriding or cancelling out each other.

   If this is *not* what you meant, please just rephrase your question =)

   Best regards,
   Daniel

   Hi Daniel!
   Perfect..that's exactly what I was hoping would happen. I remember a tween library for flash I once used where you could
   have the option of it forgetting about the first completion if a new one arrived first. So I wasn't sure if that was the way it worked here.
   Great! Thanks again!
