Hi,
Indeed, it's not possible to do that, as a built in way in PlayMaker.
One way to go about this is the following:
your fsm that wants to listen to a particular global event based on logic, should have that global event as a transition of a state. and so this event will only be triggered on that fsm if it is on that state, this is very powerful indeed.
so if you send a global event "HELLO", and a fsm has its active state with the transition "HELLO" it will work, however that same fsm if it was on a different state at the time of call, would not have the transition triggering anything. It's only global transition ( when above the state) that works no matter which is the active state.
Does that make sense? this way, in your fsm logic you can start listening or stop listening to a global event this way.
However, this comes from the listener, not the Sender. If you want the sender to control to whom to send events, then you will need something more complex, for example a registration system, where fsm register themselves to a manager, and then senders contact the manager and say, I want to send this event to this fsm, and the manager look up its list of registered fsm and send that event to the right one.
Bye,
