[unity3d]Assetbundle使用示例2(支持多平

支持多平台的Assetbundle的应用示例，贴代码，供学习！

这里不同平台的StreamingAssets是不同的，所以我们要写预处理！

using UnityEngine; using System.Collections;  public class RunScript : MonoBehaviour { 	  	    //不同平台下StreamingAssets的路径是不同的，这里需要注意一下。 	    public static readonly string PathURL = #if UNITY_ANDROID 		"jar:file://" + Application.dataPath + "!/assets/"; #elif UNITY_IPHONE 		Application.dataPath + "/Raw/"; #elif UNITY_STANDALONE_WIN || UNITY_EDITOR 	"file://" + Application.dataPath + "/StreamingAssets/"; #else         string.Empty; #endif 	 	void OnGUI() 	{ 		if(GUILayout.Button("Main Assetbundle")) 		{ 			//StartCoroutine(LoadMainGameObject(PathURL + "Prefab0.assetbundle")); 			//StartCoroutine(LoadMainGameObject(PathURL +  "Prefab1.assetbundle")); 		 			StartCoroutine(LoadMainCacheGameObject(PathURL + "Prefab0.assetbundle")); 			StartCoroutine(LoadMainCacheGameObject(PathURL +  "Prefab1.assetbundle")); 		} 		 		if(GUILayout.Button("ALL Assetbundle")) 		{ 			StartCoroutine(LoadALLGameObject(PathURL + "ALL.assetbundle")); 		} 		 		if(GUILayout.Button("Open Scene")) 		{ 			StartCoroutine(LoadScene()); 		} 		 	} 	 	//读取一个资源 	 	private IEnumerator LoadMainGameObject(string path) 	{ 		 WWW bundle = new WWW(path); 		  		 yield return bundle; 		  		 //加载到游戏中 		 yield return Instantiate(bundle.assetBundle.mainAsset); 		  		 bundle.assetBundle.Unload(false); 	} 	 	//读取全部资源 	 	private IEnumerator LoadALLGameObject(string path) 	{ 		 WWW bundle = new WWW(path); 		  		 yield return bundle; 		  		 //通过Prefab的名称把他们都读取出来 		 Object  obj0 =  bundle.assetBundle.Load("Prefab0"); 		 Object  obj1 =  bundle.assetBundle.Load("Prefab1"); 		 		 //加载到游戏中	 		 yield return Instantiate(obj0); 		 yield return Instantiate(obj1); 		 bundle.assetBundle.Unload(false); 	} 	 	private IEnumerator LoadMainCacheGameObject(string path) 	{ 		 WWW bundle = WWW.LoadFromCacheOrDownload(path,5); 		  		 yield return bundle; 		  		 //加载到游戏中 		 yield return Instantiate(bundle.assetBundle.mainAsset); 		  		 bundle.assetBundle.Unload(false); 	} 	 	 	private IEnumerator LoadScene() 	{ 		 WWW download = WWW.LoadFromCacheOrDownload ("file://"+Application.dataPath + "/MyScene.unity3d", 1); 		  yield return download; 		  var bundle = download.assetBundle;   		  Application.LoadLevel ("Level"); 	} 	 }
