此问题已解决、

加载逻辑有问题，WWW 的并发太高导致通讯堵塞造成的、修改加载逻辑，保证WWW的低并发就ok了

环境描述

因热更需求，项目4.x升级 5.x

Unity5.6 + windows

AssetBundle打包方式：

1、命名AssetBundleName：文件路径+文件名称+ .myBundle 后缀

Example: assets/resources/gui/tracktaskui.prefab.mybundle （总共有一万+ 个文件）

使用Unity5.x 最新打包函数

    [MenuItem("Assetbundle/3_ExportBundle")]    static void ExportBundle() {        EditorUtility.DisplayCancelableProgressBar("ExportBundle", "", 0.5f);        // Choose the output path according to the build target.        string outputPath = Path.Combine("MyAssetBundles", GetPlatformName());        if (!Directory.Exists(outputPath))            Directory.CreateDirectory(outputPath);        //@TODO: use append hash... (Make sure pipeline works correctly with it.)        BuildPipeline.BuildAssetBundles(outputPath, BuildAssetBundleOptions.None, EditorUserBuildSettings.activeBuildTarget);    }

打包出来的资源路劲

 file://F:/ThreeKingdom_5_6/ThreeKingdom185_temp1/Assets/../MyAssetBundles/Android/assets/resources/gui/tracktaskui.prefab.mybundle

首先、我会加载 Android（AssetBundle）

然后把依赖描述文件（Android.manifest）读取出来

    private AssetBundle main_manifestBundle;    private AssetBundleManifest main_manifest;    public void Init() {        // 1.加载main_Manifest文件          path = GetBundlePath("Android");        if (File.Exists(path))            main_manifestBundle = AssetBundle.LoadFromFile(path);        else            Debug.LogError("file not found：" + path);        main_manifest = (AssetBundleManifest)main_manifestBundle.LoadAsset("AssetBundleManifest");    }

然后就是读取资源了用www 从本地读取：

在原有框架上直接改

LoadAsset、LoadUIAsset俩个函数，同时在项目配置中增加个bool 这样就不会干扰到原有逻辑 UseMyAssetBundle=true

    public void LoadAsset(string prefab, Action<Object> loaded, Action<float> progress) {        if (SystemSwitch.UseMyAssetBundle) {            StartCoroutine(LoadMyAssetBundle(prefab, loaded, progress,"LoadAsset"));        } else {            var path = m_filesDic.Get(prefab);            //LoggerHelper.Debug(path);            LoadAssets(path, m_queue, ResourceManager.LoadResource, loaded, (resource) => {                if (progress != null && resource != null)                    StartCoroutine(ShowProgress(resource, progress));            });            //StartCoroutine(WaitAndDo(path, loaded));        }    }

    public void LoadUIAsset(string prefab, Action<Object> loaded, Action<float> progress)    {        if (SystemSwitch.UseMyAssetBundle) {             Debug.Log("LoadUIAsset  " + prefab);            StartCoroutine(LoadMyAssetBundle(prefab, loaded, progress, "LoadUIAsset"));        } else {            var path = m_filesDic.Get(prefab);            DebugFilesDicPatp(path, prefab);            //LoggerHelper.Debug(path);            LoadAssets(path, m_queue, ResourceManager.LoadUIResource, loaded, (resource) => {                if (progress != null && resource != null)                    StartCoroutine(ShowProgress(resource, progress));            });            //StartCoroutine(WaitAndDo(path, loaded));        }    }

    private Dictionary<string, WWW> loadingDic = new Dictionary<string, WWW>();     private IEnumerator LoadMyAssetBundle(string prefab, Action<Object> loaded, Action<float> progress,string loadType) {        prefab = prefab.ToLower();        AssetBundle bundle = new AssetBundle();        string pathTemp = string.Empty;        string prefabTemp = string.Empty;        if (prefab.Contains(".mp3"))            prefabTemp = "mp3";        else if (prefab.Contains(".unity")) {            if (loaded != null)                loaded(null);        } else            prefabTemp = prefab;        Debug.LogError("wwCount: "+loadingDic.Count);        if (MogoWorld.myAssetsManager.MyAssetBundlePathDic.TryGetValue(prefabTemp, out pathTemp)) {            if (MogoWorld.myAssetsManager.AlreadyLoadAssetBundle.TryGetValue(pathTemp, out bundle)) {                if (loaded != null)                    loaded(bundle.LoadAsset(prefab));            } else {                string url = SystemConfig.MyAssetBundlePath + pathTemp;                Debug.Log(url);                WWW ww;                if (loadingDic.ContainsKey(pathTemp)) {                    ww = loadingDic[pathTemp];                } else {                    ww = new WWW(url);                    loadingDic.Add(pathTemp, ww);                }                yield return ww;                if (ww.isDone) {                    loadingDic.Remove(pathTemp);                    if (MogoWorld.myAssetsManager.AlreadyLoadAssetBundle.ContainsKey(pathTemp)) {                        LoadAsset(prefab, loaded, progress);                    } else {                        bundle = ww.assetBundle;                        MogoWorld.myAssetsManager.AlreadyLoadAssetBundle.Add(pathTemp, bundle);                        string[] depends = MogoWorld.myAssetsManager.MainAssetBundleManifest.GetAllDependencies(pathTemp);                         ww.Dispose();                        StartCoroutine(LoadMyAssetBundleDepends(prefab, loaded, progress, depends, 0, loadType));                    }                }            }        }    }

    private IEnumerator LoadMyAssetBundleDepends(string prefab, Action<Object> loaded, Action<float> progress, string[] depends, int curStep, string loadType) {        if (curStep < depends.Length) {            AssetBundle bundle = new AssetBundle();            string path = string.Empty;            path = depends[curStep];            if (MogoWorld.myAssetsManager.AlreadyLoadAssetBundle.TryGetValue(path, out bundle)) {                curStep++;                StartCoroutine(LoadMyAssetBundleDepends(prefab, loaded, progress, depends, curStep, loadType));            } else {                if (loadingDic.ContainsKey(depends[curStep])) {                    curStep++;                    StartCoroutine(LoadMyAssetBundleDepends(prefab, loaded, progress, depends, curStep, loadType));                } else {                    WWW ww = new WWW(SystemConfig.MyAssetBundlePath + path);                    yield return ww;                    if (ww.isDone) {                        bundle = ww.assetBundle;                        MogoWorld.myAssetsManager.AlreadyLoadAssetBundle.Add(path, bundle);                        curStep++;                        StartCoroutine(LoadMyAssetBundleDepends(prefab, loaded, progress, depends, curStep, loadType));                    }                }            }        } else {            if (loadType == "LoadAsset") {                LoadAsset(prefab, loaded, progress);            } else if (loadType == "LoadUIAsset") {                LoadUIAsset(prefab, loaded, progress);            }        }     }

LoadAsset 与LoadUIAsset 这俩个函数为原系统加载AssetBundle的方法、我下面贴一个调用的例子

这个是调用LoginUI.prefab 的例子

public void ShowMogoLoginUI(Action callback, Action<float> progress = null)    {        if (!UICanChange)            return;        //if (CurrentUI)        //    CurrentUI.SetActive(false);        //CurrentUI = m_LoginUI;        //CurrentUI.SetActive(true);        //if (MogoMainCamera.instance)        //    MogoMainCamera.instance.SetActive(false);        //m_camUI.clearFlags = CameraClearFlags.Depth;        //ShowBillboardList(false);        if (m_LoginUI == null)        {            if (!IsLoginUILoaded)            {                IsLoginUILoaded = true;                //CallWhenUILoad(0,false);                AssetCacheMgr.GetUIInstance("LoginUI.prefab",//LoginUI                    (prefab, guid, go) =>                    {                        m_LoginUI = go as GameObject;                        m_LoginUI.transform.parent = GameObject.Find("MogoMainUIPanel").transform;                        m_LoginUI.transform.localPosition = new Vector3(1.25f, -52f, 0);                        m_LoginUI.transform.localScale = new Vector3(1, 1, 1);                        m_LoginUI.AddComponent<LoginUIViewManager>();                        if (CurrentUI != m_LoginUI)                        {                            if (CurrentUI != null)                            {                                ShowCurrentUI(false);                            }                            CurrentUI = m_LoginUI;                            ShowCurrentUI(true);                            m_camUI.clearFlags = CameraClearFlags.Depth;                            //if (MogoMainCamera.instance)                            //    MogoMainCamera.instance.SetActive(false);                            ShowBillboardList(false);                            if (callback != null)                            {                                callback();                            }                            //MogoGlobleUIManager.Instance.ShowWaitingTip(false);                        }                    }, progress);            }        }        else        {            if (CurrentUI != m_LoginUI)            {                ShowCurrentUI(false);                CurrentUI = m_LoginUI;                ShowCurrentUI(true);                m_camUI.clearFlags = CameraClearFlags.Depth;                ShowBillboardList(false);                //if (MogoMainCamera.instance)                //    MogoMainCamera.instance.SetActive(false);                if (callback != null)                {                    callback();                }            }        }    }

那么现在问题出在协程递归的地方
