我有以下场景

包含带有音频源组件的游戏对象的主菜单场景
一个关于我们的场景

gameObject脚本：

using UnityEngine;
using System.Collections;

public class ManageMusic : MonoBehaviour
{
    private static ManageMusic _instance;

    public static ManageMusic instance
    {
        get
        {
            if (_instance == null)
            {
                _instance = GameObject.FindObjectOfType<ManageMusic>();

                //Tell unity not to destroy this object when loading a new cene!
                DontDestroyOnLoad(_instance.gameObject);
            }

            return _instance;
        }
    }

    private void Awake()
    {
        if (_instance == null)
        {
            Debug.Log("Null");
            //If I am the first instance, make me the Singleton
            _instance = this;
            DontDestroyOnLoad(this);
        }
        else
        {

            //If a Singleton already exists and you find
            //another reference in scene, destroy it!
            if (this != _instance)
            {
                Play();
                Debug.Log("IsnotNull");
                Destroy(this.gameObject);
            }
        }

    }
    public void Update()
    {
        if (this != _instance)
        {
            _instance = null;
        }
    }
    public void Play()
    {
        this.gameObject.audio.Play();
    }
}

关于我们返回按钮脚本：

using UnityEngine;
using System.Collections;

public class Back_btn : MonoBehaviour 
{
     void OnMouseDown() 
     {
        Application.LoadLevel("MainMenu");

     }
 }

enter image description here

当我点击aboutUs按钮时， Game Music object 继续播放，我可以听到音乐，但是当我返回主菜单时，仍然没有播放音乐 . 当我回到主菜单并且音频监听器将音量值设置为 1 时，我可以看到游戏对象没有被破坏，但我无法弄清楚问题是否有人可以帮助我

你需要一个单身人士 . Unity Patterns有a great post about singleton usage in Unity3D environment . 尝试实现网站中指定的 Persistent Singleton 模式 .

有时您需要单身人士在场景之间持续（例如，在这种情况下，您可能希望在场景转换期间播放音乐） . 一种方法是在你的单身人士上调用DontDestroyOnLoad（） .

public class MusicManager : MonoBehaviour 
{
    private static MusicManager _instance;

    public static MusicManager instance
    {
        get
        {
            if(_instance == null)
            {
                _instance = GameObject.FindObjectOfType<MusicManager>();

                //Tell unity not to destroy this object when loading a new scene!
                DontDestroyOnLoad(_instance.gameObject);
            }

            return _instance;
        }
    }

    void Awake() 
    {
        if(_instance == null)
        {
            //If I am the first instance, make me the Singleton
            _instance = this;
            DontDestroyOnLoad(this);
        }
        else
        {
            //If a Singleton already exists and you find
            //another reference in scene, destroy it!
            if(this != _instance)
                Destroy(this.gameObject);
        }
    }

    public void Play()
    {
        //Play some audio!
    }
}
