AssetBundle

1.  生成 AssetBundle 文件

　　Editor 文件夹下添加代码：

[MenuItem("Assets/Build AssetBundles")]
    static void BuildAllAssetBundles()
    {
        string assetBundleDirectory = "Assets/AssetBundles";
        if(!Directory.Exists(assetBundleDirectory)
        {
            Directory.CreateDirectory(assetBundleDirectory);
        }
        BuildPipeline.BuildAssetBundles(assetBundleDirectory,         
        BuildAssetBundleOptions.None, BuildTarget.Standalone);
    }    

2. 划分文件夹

　　指定 AssetBundle 时文件夹之间用 / 分开。

3.  加载资源

function Start() {
   var myLoadedAssetBundle = AssetBundle.LoadFromFile(Path.Combine(Application.streamingAssetsPath, "myassetBundle"));
   if (myLoadedAssetBundle == null) {
       Debug.Log("Failed to load AssetBundle!");
       return;
   }
   var prefab = myLoadedAssetBundle.LoadAsset.<GameObject>("MyObject");
   Instantiate(prefab);}
