Issue with playing background audio for different scenes in unity3d

Question

In my game, I have two scene. What I want to achieve is if user navigates from one scene to another, background audio specific to each should be played from start(audio length=0)

But all my efforts are in vain.

I tried using 'Pause' Method of audioSound I tried create a new game object and assign this scene background score to it and play destroy gameObject created for another scene if there was any

But it doesn't give the result that I want.

I searched for finding how to play audioClip from start and stop other audioClip playing but didn't find any.

I know I'm not supposed to ask for code on stack overflow but if anyone has achieved this or has some pseudo code request you to provide it

Answer 1

I'm not sure I understand your question properly, since it seems the simplest scenario for background music.

If you really want a change of audioclip in every scene, let's say Scene A must play Clip A and Scene B must play Clip B, and both clips should be played as soon as a scene is loaded, you just need to create a game object in both scenes with an Audio Source component, with the Play On Awake flag active, and then just assign the appropriate clip for the scene (i.e.: assign Clip A in the Audio Clip field of the Audio Source component of Scene A game object, and do the same with Clip B for Scene B).

That's pretty much it.

Answer 2

If you looking at the detail code then you can try this code.

First : Make a script "SoundFxScript.cs" // You can modified as you want

Insert this code :

public class SoundFxScript : MonoBehaviour {
    //Background Music

    public AudioSource Scene1_Sound;
    public AudioSource Scene2_Sound;

    // Use this for initialization
    void Start () {
        PlayBackgroundMusic ();
    }

    // Update is called once per frame
    void Update () {

    }

    public void PlayBackgroundMusic() {
        if (UnityEngine.SceneManagement.SceneManager.GetActiveScene ().name == "Scene1") {
            Scene1_SoundPlay();
        } else if (UnityEngine.SceneManagement.SceneManager.GetActiveScene ().name == "Scene2") {
            Scene2_SoundPlay();
        } 
    }

    public void Scene1_SoundPlay() {
        Scene1_Sound.Play ();
        Scene2_Sound.Stop ();
    }

    public void Scene2_SoundPlay() {
        Scene1_Sound.Stop ();
        Scene2_Sound.Play ();
    }


// Step Fifth
public void LoadTheScene (string Scenename) {
            UnityEngine.SceneManagement.SceneManager.LoadScene (Scenename);
            sf.PlayBackgroundMusic ();

        }
}

Second : Make Gameobject name = "SoundMusic" at the first scene and add component script SoundFxScript.cs. In gameobject "SoundMusic" you can add you background music for scene1 and scene2.

Third : Make a singleton file Singleton.cs

Insert this code :

public class Singleton : MonoBehaviour {
    static Singleton instance = null;

    void Start ()
    {
        if (instance != null)
        {
            Destroy(gameObject);
            return;
        }

        DontDestroyOnLoad(gameObject);
        instance = this;
    }

}

Fourth : at gameobject "SoundMusic" add component script "Singleton.cs"

Fifth : How To Call In Another Scene (Load Scene). This method is inside SoundFxScript.cs

Example You have a method to call a load scene. Try this method :

Call it with : LoadTheScene("Scene2") // Call scene2

In here you can call your SoundFxscript.cs Component from any script you have.

Example :

SoundFxScript sf;
sf = GameObject.Find ("SoundMusic").GetComponent<SoundFxScript> ();

And you can use method LoadTheScene to load a new scene and the background music will RePlay again according to the what Scene is it.

That's All.
