How do I reference an EventInstance in another script?

Unity

How do I set a paremeter, or stop an event instance from script B, when script A has the instance of the event?

Is there a way to allow a game designer to drag and drop an event instance from a separate script into a unity inspector? I was unable to get this working.

Of course I can use GetComponent, but that means we have to code this every time and it’s not scalable.

There are many ways you could do this. The easiest I can think of would be to create a static method in Script A that stops or sets a parameter on an event instance:

public class ScriptA
{
    static EventInstance eventInstance;

    public static void StopEventInstance()
    {
        eventInstance.stop(FMOD.Studio.STOP_MODE.IMMEDIATE);
    }
}

class ScriptB
{
    void Stop()
    {
        ScriptA.StopEventInstance();
    }
}

You can drag EventReference path from the Event Browser into an FMODUnity.EventReference field in the inspector, so you can look at “Assets\Plugins\FMOD\src\Editor\EventBrowser.cs” for a reference. I think implementing Drag and Drop in the Unity Editor is a little out of scope for the forums, but here is a Unity Editor tutorial on how this works.
