Muting audio when interacting with game object in unity

Unity
1

Hey! I’m struggling to figure out how to get this setup to work: I have a radio object which I can interact with in Unity, and I want this interact to toggle between muting and unmuting a continuously playing FMOD event. How would I implement this?

I’m quite new to FMOD Unity by the way

Hi,

Thank you for sharing the information.

If your radio object is using a StudioEventEmitter, a simple way is to toggle the volume of its event instance when the object is interacted with.

For example:

using UnityEngine;
using FMODUnity;

public class RadioMuteToggle : MonoBehaviour
{
    public StudioEventEmitter radioEmitter;
    private bool muted;

    private void Update()
    {
        // press P to test mute/unmute
        if (Input.GetKeyDown(KeyCode.P))
        {
            Interact();
        }
    }

    public void Interact()
    {
        muted = !muted;
        radioEmitter.EventInstance.setVolume(muted ? 0f : 1f);
    }
}

Add this script to your radio object, assign the same StudioEventEmitter to radioEmitter, then press P to test it. In your own project, you can call Interact() from your interaction system instead.

This mutes/unmutes the radio while the event keeps playing in the background.

If you want the radio to pause instead, you can use Studio::EventInstance::setPaused instead of Studio::EventInstance::setVolume in Interact().

For example:

radioEmitter.EventInstance.setPaused(muted);

Hope this helps!

Thanks for the reply!! I have no code experience, so could you explain more what you mean by “In your own project, you can call Interact() from your interaction system instead.”? We have the code set up to interact with the radio but how do I connect that to this muting code?

I’m also confused by "assign the same StudioEventEmitter to radioEmitter". How do I do this?
