How to play sound while changing scene?

I am trying to make a sound while i change scene but the sound get cut while doing it.
I tryed this:

Code (CSharp):

1.     void Awake()
2.     {
3.          if (instance == null) { instance = this; } else { Destroy(gameObject); return; }
4.            DontDestroyOnLoad(gameObject);
5. }

But it did'nt work.

 

I'm not sure what destroying a gameobject has to do with your question. All you do is set DontDestroyOnLoad on the GameObject with the audiosource, start playing it, then change the scene. You probably will want to set the audiosource to entirely 2D so it doesn't change in volume with a new audio listener in the new scene at a different location.

I do this all the time to keep music playing while switching scenes, works fine.

 

It's for preventing multiple objects.

 

Just have a manager class that keeps track of if you have started a sound and either a) reuses it the next time, or b) destroys it and creates a fresh one.

You can also explicitly destroy the GameObject after the sound is done.
