AssetBundle加载的四种方式（补充 三，四）

  #region 第三种类型     /// <summary>    /// 路径有本地和远程，本地可以加file:// 或者file:/// 路径要完整的本地路径，这个位置卡了很久，经过多次尝试得到最终正确的路径    /// </summary>    /// <param name="path"></param>    /// <returns></returns>    ///     //在Start方法中调用 参数为自己本地最终正确路径      //StartCoroutine(LoadFromCacheOrDownload(@"file://F:\PrivateForWCW\Unity\UGUI\AssetBudleProject\AssetBundle\scene\cubewall.unity3d"));   /// 服务器上  StartCoroutine(LoadFromCacheOrDownload(@"http://localhost//AssetBundless/scene/cubewall.unity3d"));    IEnumerator LoadFromCacheOrDownload(string path)    {        while (!Caching.ready)            yield return null;        WWW www = WWW.LoadFromCacheOrDownload(path, 1);        yield return www;        if (!string.IsNullOrEmpty(www.error))        {            Debug.Log(www.error);            yield break;        }        AssetBundle AB = www.assetBundle;        GameObject obj=AB.LoadAsset<GameObject>("cube");        Instantiate(obj);    }    #endregion    #region 第四种 UnityWebRequst  //这个UnityWebRequst相当与取代了WWW这个类，还进一步优化了    //使用  UnityWebRequest 需要引入UnityEngine.Networking;    IEnumerator LoadFormWebRequst()    {        string uri = @"http://localhost//AssetBundless/scene/cubewall.unity3d";        UnityWebRequest request = UnityWebRequest.GetAssetBundle(uri);        yield return request.Send();        //   AssetBundle AB = DownloadHandlerAssetBundle.GetContent(request); 第一种方式获取AssetBundle        AssetBundle AB = (request.downloadHandler as DownloadHandlerAssetBundle).assetBundle;// 第二种方式获取AssetBundle        GameObject obj = AB.LoadAsset<GameObject>("cube");        Instantiate(obj);    }    #endregion
