unity3d 加载文件

1. 单个大图加载：

在 unity editor 模式下，先通过

string[] assetPaths = AssetDatabase.GetAssetPathsFromAssetBundleAndAssetName(abname, assetname);

Sprite sprite = AssetDatabase.LoadAssetAtPath<Sprite>(assetPaths[0]);

可以获得 sprite

AssetBundleCreateRequest   m_abcr

在非 unity editor 模式下，先加载 assetBundle ，等 m_abcr.isDone 完成，

string uri = Util.DataPath + abname;

m_abcr = AssetBundle.LoadFromFileAsync(uri);

Sprite sprite = m_abcr.assetBundle.LoadAsset<Sprite>(m_assetname);

2.  加载  prefab  ：

在 unity editor 模式下，

string[] assetPaths = AssetDatabase.GetAssetPathsFromAssetBundleAndAssetName(abname, assetname);

GameObject go =  AssetDatabase.LoadAssetAtPath<GameObject>(assetPaths[0]); 

非 editor 模式：

AssetBundle bundle = LoadAssetBundle(abname, dontDestroy);

bundle = AssetBundle.LoadFromFile(uri);

GameObject go = bundle.LoadAsset<GameObject>(assetname);

3. 加载 audio 类似 加载 prefab
