Hi

I’m sure I’m being a numpty but I can’t figure out why this isn’t working. I’m starting an event in a start method and then stopping the same event in the same script but it’s not working. If I put in an else it just tells me the stop method wasn’t working. If I use an FMOD emitter (as in the image) it works but I probably need to call this separately and not via game objects. The script has the non-functional bits commented out. Thanks J

OK I very much feel that I should have a better handle on handles 🤣  
If someone can take pity and explain this to me it’d be very helpful.  
So if I start the music in the Start method of the “MusicManager” it’ll have an invalid handle when I call it from the animation event via this UnityEvent trigger script. If I instead add an OnEnable method in that script the logic works? So does an event always have to be called from the same object?

Hi,

I am a bit confused, Using your script I was able to play the event from the `start()` function. I would suggest adding some error checking in order to find where it is failing:

```auto
private void StudyMusic()
{
    studyMusic = FMODUnity.RuntimeManager.CreateInstance("event:/Music/Level 01");
    if (studyMusic.isValid())
    {
        FMOD.RESULT result = studyMusic.start();
        if (result != FMOD.RESULT.OK)
        {
            Debug.Log(result.ToString());
        }
    }
}

```

Using the `isValid()` ([FMOD Engine | Studio API reference - EventInstance](https://fmod.com/docs/2.02/api/studio-api-eventinstance.html#studio_eventinstance_isvalid)) will let us know if the `CreateInstance()` function failed. Next is `FMOD.RESULT` ([FMOD Engine | Core API Reference - FMOD\_RESULT](https://fmod.com/docs/2.02/api/core-api-common.html#fmod_result)) is returned from most FMOD functions and provides more information about why an FMOD Function may have failed.

It seems if the `StudyMusic()` function is failing there may be an issue with the path passed to the `CreateInstance()` function.

Not necessarily, it should be possible. What is the object triggering the `MusicManager` in this image?

Thanks and sorry for my late reply. This was a game jam project and somewhere along the line, the FMOD folder got moved around in the Unity project. I went back and had a look and I can only think that this is the reason for the weird behaviour.

Hi,

Thank you for sharing the solution. Hope the game jam went well!
