unity不使用協程，加載assetbundle包

公司的項目準備用ab包的形式開發，而加載ab包的功能放在一個沒有繼承MonoBehaviour的類中，全部在加載ab包的時候，無法用協程來判斷ab包是否加載完成，因此我本身用了一種方式來判斷；

我用的事異步加載ab包，

AssetBundleCreateRequest asset = AssetBundle.LoadFromFileAsync(path);

　　固然還有其餘的加載方式，網上有不少大神都對此有很詳細的描述，這裏我就不在贅述了，咱們能夠經過委託 asset.completed，當單個資源包加載完成後，要執行的事；

void LoadAssetsBundle()
        {
            m_Path = Application.dataPath;
            //獲取運行文件的同級目錄
            Directory.SetCurrentDirectory(Directory.GetParent(m_Path).FullName);
            m_Path = Directory.GetCurrentDirectory();
            string assetBundlenPath = ConfigManager.Instance().GetAssetBundlePath();
            m_Path += "/"+ assetBundlenPath;

            m_AssetsNameList = ConfigManager.ReadAssetBundleName();

            string path = m_Path + "/" + m_AssetsNameList[0];

            AssetBundleCreateRequest asset = AssetBundle.LoadFromFileAsync(path);
            asset.completed += AssetBundleLoadcompleted;
           

        }

        private void AssetBundleLoadcompleted(AsyncOperation asset)
        {
            AssetBundleCreateRequest assetBundle = (AssetBundleCreateRequest)asset;
            if (asset == null)
            {
                Debug.Log(m_AssetsNameList[m_Index] + "加載失敗");
            }
            else
            {
                Debug.Log(m_AssetsNameList[m_Index] + "加載成功");
                m_AssetBundleList.Add(assetBundle.assetBundle);
            }

            if (m_Index < m_AssetsNameList.Count - 1)
            {
                m_Index++;
                //LoadAsset(m_Index);
                string path = m_Path + "/" + m_AssetsNameList[m_Index];

                if (!File.Exists(path))
                {
                    Debug.Log(m_AssetsNameList[m_Index] + " AssetBundle包文件不存在", LogType.Error);
                    return;
                }
                AssetBundleCreateRequest NextAsset = AssetBundle.LoadFromFileAsync(path);
                NextAsset.completed += AssetBundleLoadcompleted;
                
            }
            else
            {
                Debug.Log(m_AssetsNameList.Count + "個資源包所有加載完成");
                for (int i = 0; i < m_AssetBundleList.Count; i++)
                {
                    Debug.Log(m_AssetBundleList[i].name);
                }
                
            }
        }

　　上述代碼中有些方法是公司項目中自定義的，須要稍加修改。
