1、加载本地资源：

using UnityEngine;using System.Collections;public class LoadResources : MonoBehaviour {private AudioSource _Audio;IEnumerator Start(){_Audio=this.gameObject.AddComponent<AudioSource>();WWW www=new WWW(string.Format("file://{0}/music.unity3d",Application.dataPath));yield return www;if(www.error==null){_Audio.clip=www.assetBundle.mainAsset as AudioClip;}else Debug.LogError(www.error);}void Update(){if(!_Audio.isPlaying)_Audio.Play();}}

2、加载远程资源：

using UnityEngine;using System.Collections;public class LoadResources : MonoBehaviour {private AudioSource _Audio;IEnumerator Start(){_Audio=this.gameObject.AddComponent<AudioSource>();WWW www=new WWW("http://127.0.0.1/music.unity3d");yield return www;if(www.error==null){_Audio.clip=www.assetBundle.mainAsset as AudioClip;}else Debug.LogError(www.error);}void Update(){if(!_Audio.isPlaying)_Audio.Play();}}

也可以这样写：

using UnityEngine;using System.Collections;public class LoadResources : MonoBehaviour {private AudioSource _Audio;void Start(){_Audio=this.gameObject.AddComponent<AudioSource>();StartCoroutine(Load());}private IEnumerator Load(){WWW www=new WWW(string.Format("file://{0}/music.unity3d",Application.dataPath));yield return www;if(www.error==null){_Audio.clip=www.assetBundle.mainAsset as AudioClip;}else Debug.LogError(www.error);}void Update(){if(!_Audio.isPlaying)_Audio.Play();}}

或者这样写：

using UnityEngine;using System.Collections;public class LoadResources : MonoBehaviour {private AudioSource _Audio;IEnumerator Start(){_Audio=this.gameObject.AddComponent<AudioSource>();return Load();}private IEnumerator Load(){WWW www=new WWW(string.Format("file://{0}/music.unity3d",Application.dataPath));yield return www;if(www.error==null){_Audio.clip=www.assetBundle.mainAsset as AudioClip;}else Debug.LogError(www.error);}void Update(){if(!_Audio.isPlaying)_Audio.Play();}}

如果发布成WebGame，则需要在网站中添加跨域访问策略文件crossdomain.xml。

<?xml version="1.0"?><cross-domain-policy>  <allow-access-from domain="*" header="*" /></cross-domain-policy>
