[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");    }        }
