Unity之如何从fbx提取Animation clip文件

见代码：

     static void CreateAnim(string fbx, string target)
     {
         AnimationClip src = AssetDatabase.LoadAssetAtPath<AnimationClip>(fbx);
         AnimationClip temp = new AnimationClip();
         EditorUtility.CopySerialized(src, temp);
         CreateDirectory(target);
         AssetDatabase.CreateAsset(temp, target);
     }
