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);

     }
