Playing audio through multiple scenes

Question

Hi I found this video on YouTube, about playing music through multiple scenes without the sound breaking:

Playing Seamless Music Across Scenes in Unity 5 With Non-Destroyable Object

Here is the code from the video:

 using UnityEngine;
 using System.Collections;
  
 public class DontDestroy : MonoBehaviour {
  
     void Awake ()
     {
         GameObject[] objs = GameObject.FindGameObjectsWithTag("music");
         if (objs.Length > 1)
             Destroy(this.gameObject);
  
         DontDestroyOnLoad(this.gameObject);
  
     }
 }

You attach it to the GameObject that has an audio, and create a tag for it so you can call it in script.

I was just wondering is it possible to add lines to the same code so that once it enters a certain scene, this GameObject stops appearing in it... the audio doesn't play for that scene...

Okay, so this is the code I used, and it does what I wanted (Unity 5.4):

 using UnityEngine;
 using System.Collections;
 using UnityEngine.SceneManagement;
 
 public class DontDestroy : MonoBehaviour {
 
     void Awake ()
     {
         GameObject[] objs = GameObject.FindGameObjectsWithTag("music");
         if (objs.Length > 1)
             Destroy(this.gameObject);
 
         DontDestroyOnLoad(this.gameObject);
 
     }
 
     void Update()
     {
         if (SceneManager.GetActiveScene().name == "SceneName")
         {
             Destroy(this.gameObject);
         }
     }
 }

Instead of a 'SceneName', you write your own name of the scene where you want audio to stop. Hope this might help someone out. Peace.

EDIT: If you have multiple scenes to go from these, that keep playing the audio, and you want to stop it in multiple instances, just copy the...

 if (SceneManager.GetActiveScene().name == "SceneName")
         {
             Destroy(this.gameObject);
         }

... and add the other scene name.

how about when back to the previous scene? Since the dontdestroyonload's object is destroyed, so the music won't play anymore, what if I want to play the music rat the previous scene? (Scene 1 > Scene 2 > Scene 3 ) - Destroy dontdestroyonload's object in scene 3, but want to play the same music when I switch from (Scene 3 > Scene 2/ Scene 1) without stop or restart the music.

@YoYoYoYo_111_PiPi I tried using this script, but I get this error:

Assets/Scripts/DontDestroy.cs(21,27): error CS0117: SceneManager' does not contain a definition for GetActiveScene'

Do you know why it might be?

I am not sure, I haven't been using Unity lately. So i also haven't updated it either... I know that with new updates Unity also changes the code language. Though 'Scene$$anonymous$$anager.GetActiveScene' is still there in the official scripting documents:

https://docs.unity3d.com/ScriptReference/Scene$$anonymous$$anagement.Scene$$anonymous$$anager.GetActiveScene.html

Check if you have used everything correctly as in the code above (stuff like 'using UnityEngine.Scene$$anonymous$$anagement;') and you have to type the name of your scene, whatever it is called, ins$$anonymous$$d of "SceneName", as given in example. If you still have problems with it, please also check out the Unity forums for that error, because I can't say for myself that I'm a coding expert in any way, and I've used that one quite a while ago.

Cheers.

Do you have " using UnityEngine.Scene$$anonymous$$anagement; " at the top of your script?
