Hi,
ok, I have added start and exit setup, but events can't go in as playing HOTween this way doesn't give you access to feedback so I can't know anything about the current process when you play tween this way.
If you have a particular need, I would contact the author, maybe there is a trick that I am not aware of, if there is a working sample or script, then I can turn it into a playmaker action or fsm.
bye,
Jean
