根据自己的情况仿照雨松MOMO 写了一个自动生成动画的脚本原地址 http://www.xuanyusong.com/archives/3243

代码：

这样做有个问题，每一次点击BuildAnimation都会重新加载所有资源，如果数据量大的话，更新会很不方便。

有以下修改：

    [MenuItem("Assets/BuildAnimation")]    static void BuildAnimations()    {        //选中的文件夹，不包括子文件夹        UnityEngine.Object[] filter = Selection.GetFiltered(typeof(UnityEngine.Object), SelectionMode.TopLevel);        //路径中包含"Raw" 或者选中的是"Raw"        if (!AssetDatabase.GetAssetPath(filter[0]).Contains("Raw") || Path.GetFileNameWithoutExtension(AssetDatabase.GetAssetPath(filter[0])) == "Raw")        {            Debug.LogError("没有选中对的文件夹");            return;        }        DirectoryInfo[] filterInfo = new DirectoryInfo[filter.Length];        for (int i = 0; i < filter.Length; i++)        {            filterInfo[i] = new DirectoryInfo(Application.dataPath.Substring(0,Application.dataPath.LastIndexOf("/")) + "/" + AssetDatabase.GetAssetPath(filter[i]));        }        foreach (DirectoryInfo directories in filterInfo)        {            List<AnimationClip> clips = new List<AnimationClip>();            foreach (DirectoryInfo ActionList in directories.GetDirectories())            {                List<AnimationClip> clipList = BuildAnimationList(ActionList);                foreach (AnimationClip clip in clipList)                {                    clips.Add(clip);                }            }            AnimatorController controller = BuildAnimationController(clips, directories.Name);            BuildPrefab(directories, controller);        }    }

这样写，只会Build选中的文件夹。
