Play Audio in Queue

Question

Hey guys,

I have a single Object which has an Audio Source due to only wanting a single audio to play at a time. Besides that i have various interactables which can be clicked in order to play a sound, meaning clicking an object will tell the game manager which sound he should play… this all works fine so far, however when playing two sounds quickly after another only the second sound gets played, which makes sense since only a single Audio Source is present I assume.

What I am looking for is a way to queue Audio files in the game Manager and then play these in a row one after another…

I guess whenever I tap an interactable, I would need to add its Audio Clip to a list, the game manager than plays through the list and deletes the clip from the list once it got played correct ?

But how would you do this ? Using Corountines to determine if the Audio Source is still playing, or rather use PlayScheduled ?

Would be really grateful for some hints and thoughts.

Answer 1

For me, I would have a SoundManager" script. So I can just use a PlaySound(clip); method whenever I need to. So the SoundManger could look something like this:

public class SoundManager : Monobehaviour
{
    public AudioSource audioSource;
    Queue<AudioClip> clipQueue;
  
    void FixedUpdate()
    {
	    if (audioSource.isPlaying == false && clipQueue.Count > 0) {
	        audioSource.clip = clipQueue.Dequeue();
            audioSource.Play();
	    }
    }
    public void PlaySound(AudioClip clip)
    {
        clipQueue.Enqueue(clip);
    }
}

Faints

Works like magic, thanks!

if you use a Queue, don't forget to initialize it with clipsQueue = new Queue<AudioClip>(); or it will not work ¯\\(°_o)/¯

Prefer AudioSource.PlayScheduled().

docs.unity3d.com

Unity - Scripting API: AudioSource.PlayScheduled

From the docs:

This is the preferred way to stitch AudioClips in music players because it is independent of the frame rate and gives the audio system enough time to prepare the playback of the sound to fetch it from media where the opening and buffering takes a lot of time (streams) without causing sudden CPU spikes.
