I have Fmod Studio integrated with Unity and I’m now trying to play an Fmod Studio Event on an animation’s keyframe.

On the Animation’s timeline I set a keyframe to enable the following script:

```
using UnityEngine;
using System.Collections;
using FMOD.Studio;

public class AnimationPlayFmodSound : MonoBehaviour {

	void OnEnable () {
		FMOD_StudioSystem.instance.PlayOneShot ("event:/Resources/FX/fx_column_effect", transform.position);		
	}
}

```

I thought it should play only when the script is enabled, but apparently the event plays as soon as I start the game (before the animation occurs). What am I doing wrong here?

</div>

This works for me:

```
using UnityEngine;
using System.Collections;

public class SoundEvent : MonoBehaviour {

public FMODAsset A_EventSound;
	
public void PlaySound (FMODAsset A_EventSound) {
		if(A_EventSound != null)
		{
			FMOD_StudioSystem.instance.PlayOneShot(A_EventSound, transform.position);
		}
		else
		{
			Debug.LogError("EventSound is null");
		}
		
	}
}

```

The script is attached to the root of the GameObject (model).

It works! Thanks a lot!

What is FMODAsset in this context? Another script where you kept the EventReference?

This thread is extremely old at this point - `FMODAsset` was a class in a now long-deprecated version of the FMOD for Unity plugin that stores a reference to an Event’s path and ID for the purposes of creating instances of that event at runtime. It can be considered a simplified version of, but roughly equivalent to, the `EventReference` class that is used in modern versions of the integration.
