A helpful developer explained:
The music generator provides an event "OnNotePlayed()" you can subscribe to whenever a note plays, containing the relevant information. You can suppress the playing of the note by returning false to the event and route that information wherever.
Ok, so I am near zero at scripting ability, but I know how to drag a component into an FSM and hunt through the dropdown options to Get and Set variables, and Call Method on whatever is available. I also hunted through Playmaker's Event browser, and of course this script's events are not listed there…
I think I am missing a Unity interface/function/thing, where I can tell PM to listen for this script event "OnNotePlayed()", but search is failing me ("event" is too common to get meaningful searches).
The component itself has a section for events, but "OnNotePlayed()" is not among them. (see attached)
Can anyone point me in the right direction…? How do I 'subscribe' to a script's event?
