Hi,
forgot to explain how to do that generically:
Create a Fsm Object variable, set its class to "MegaModifier", point it to the gameObject you want to control, and then use the action "set property", use that Fsm Object you have created, and you will access all the properties ( including the one I expose in this action). so you can pretty much control any component ( not just Mega Fiers ones) anything this way.
Bye,
Jean
