Event Lifecycle

Unity
1

Hi all,
i have some question about the lifecycle of an event. I’m using FMOD integrated in unity and i’m writing in C#.
1-I wanted to stop an event when it has finished playing. I don’t really understand how i can manage a sound that plays a sound in a loop. I want to command my event to “finish what you are playing and exit the loop”, but i can’t really figure out how i can do this.
2-I thought i should use the “getPlaybackState()” to debug and solve my problem, but when i print the playBackState of my event while playing i always get “STOPPED”. From what i’ve seen in documentation, “STOPPED” is when an event is not playng, but i can ear the sound of the event, and it’s why i really think i’m missing something.
The playback state is “STOPPED” also for an event that is playing a sound that is not looping.

My code is:

void Start ()
{
	eventInst = FMOD_StudioSystem.instance.GetEvent (asset);     
	eventInst.set3DAttributes (FMOD.Studio.UnityUtil.to3DAttributes (gameObject)); 
	eventInst.getPlaybackState (out s);
    eventInst.start();
}

void Update(){
    Debug.Log(s);

}

Anybody has any solution, suggestion or documentation to help me?

Thanks,
Simone

Firstly your code needs to call getPlaybackState every update to get the latest state.

If by looping you mean a loop-region on the logic track then the work flow would be:

  1. Add a parameter called trigger_finish_param to the event, leave the range at 0 to 1
  2. Change the loop-region so that it has a condition on the parameter from step 1, say only loop when the value is 0 to 0.5
  3. In unity call eventInst.setParameter(“trigger_finish_param”, 1.0f) followed by eventInst.release()

After you’ve done that the event will keep play until no instruments are active, then it will stop and clean itself up.
