Hey , im trying to create a sound effect script for jet pack jump in a game i work on.
I wondered if theres a way I could check if for example:

if Jetpack event is playing , return true

If you are managing instances you can call EventInstance::getPlaybackState to get the current playback state of an instance, something like this would work:

bool IsPlaying(FMOD.Studio.EventInstance instance) {
	FMOD.Studio.PLAYBACK_STATE state;   
	instance.getPlaybackState(out state);
	return state != FMOD.Studio.PLAYBACK_STATE.STOPPED;
}

If you are using the StudioEventEmitter components you can reference your desired emitter in code and call StudioEventEmitter::IsPlaying.

hi alex ! thanks for the replay
can you show me an example of how it is done ?
im pretty new to coding

how do I chose which event does the “isPlaying” is checking ?

I suppose you are playing sounds using the StudioEventEmitter component:

Create a new script and declare a StudioEventEmitter at the start of the class:

[SerializeField]
private FMODUnity.StudioEventEmitter emitter;

Save the script and attach it to any GameObject you want. Drag the GameObject containing the StudioEventEmitter component to the emitter field in the inspector:

Now you just can call the isPlaying method to check if that specific emitter is playing or not:

void Update()
{
    if (emitter.IsPlaying())
    {
        Debug.Log("Emitter is playing");
    }
    else if (!emitter.IsPlaying())
    {
        Debug.Log("Emitter is not playing");
    }
}

If you are still new to coding, I would suggest to take a look at Unity’s learning resources, they are great to learn how Unity works and to get basic scripting knowledge.

im actually planing on making a script with Update that checks if the sound is playing
if he’s playing do nothing , else play the sound

that kinda solves me the whole jetpack thing
how should i reference the specific Jetpack event doing so in the script
with no emitter ?

ill ask this differently , where should i put the “isPlaying” method script so i could call it anywhere on every event instance ?

cause right now i put it on some AudioManager script i have ,
and called it from a different script , and it doesnt seem to work

How are you actually playing your jetpack event? If by creating and playing an event instance in a script, then you can use the code snippet posted in my first answer in the same script.

There are different ways to go about this, you could make the method static so you can access it everywhere:

public class FmodExtensions
{    
    public static bool IsPlaying(FMOD.Studio.EventInstance instance)
    {
        FMOD.Studio.PLAYBACK_STATE state;
        instance.getPlaybackState(out state);
        return state != FMOD.Studio.PLAYBACK_STATE.STOPPED;
    }
}

Then just call FmodExtensions.IsPlaying(yourInstance) from where you want.

I finally managed to make it work ! your commends was super helpful .
I put the IsPlaying() as a public static method in my main AudioPlayer script which controls several audio commands for the entire project ,
then called it as you sayed

This is the how it works in the end :

	void Update ()
	{
		if (jetpack.UsingJet) 
		{
            if (AudioPlayer.IsPlaying(JetpackEvent))
            {
			
	        }  
	        else
	        {
	            JetpackEvent.start();
	        }
        }
        else 
        {
        	JetpackEvent.stop(FMOD.Studio.STOP_MODE.ALLOWFADEOUT);
        }
	}

yo guys also make your instance static if you want the same music to play in different scenes cuz it took me two hours to understand that
