Hi.
The system looks similar to the one on the ui components, so maybe it will work already.
Try this :
Below 'Runtime Only' drop in the gameobject with a fsm where you want to send an event (if more that 1 fsm, the fsm with the event should be on top of the other fsms in the hierarchy .)
Then click on 'No Function' and see if 'PlayMakerFSM is there.
If so, click on it and then on 'Send Event'
Then write the event name that you wish to trigger.
