AssetDatabase.RenameAsset 重命名文件失败

 

今天想写一段Unity Editor 的代码将在 Project Panel 中选中的所有 Texture 改变 Format,然后重命名 成 xxx.Dither.png 然后自动进行上一篇文章提到的 16位压缩贴图

 

刚开始改变 Format 都可以了,可是不知道如何对资源文件重命名,经过google,找到了相应API:

 

当重命名成功时会返回 空串  "" ,否则返回错误信息

 

刚开始我传入的两个参数都是 全路径的,但每次都返回错误

Trying to move asset as a sub directory of a directory that does not exist Assets/UI/Assets/UI/xxx.png

因此我把第二个参数去掉全路径,只保留新的文件名。。就成功了,以下是代码

 

 1 [MenuItem("Edit/Transform Texture To Dither")]
 2 static void SetSelectTextureToDither()
 3 {
 4     foreach(Object obj in Selection.GetFiltered(typeof(Object), SelectionMode.Assets))
 5     {
 6         string path = path = AssetDatabase.GetAssetPath(obj); ;
 7         TextureImporter textureImporter = AssetImporter.GetAtPath(path) as TextureImporter;
 8         if (textureImporter == null)
 9             continue;
10 
11         textureImporter.textureFormat = TextureImporterFormat.AutomaticTruecolor;
12         textureImporter.mipmapEnabled = false;
13 
14         AssetDatabase.WriteImportSettingsIfDirty(path);
15         string newPathName = Path.GetFileNameWithoutExtension(path) + ".Dither";
16         string renameRes = AssetDatabase.RenameAsset(path, newPathName);
17         if (renameRes != "")
18             Debug.Log("Fail to rename, err: " + renameRes);
19         AssetDatabase.WriteImportSettingsIfDirty(newPathName);
20     }
21     Debug.Log("Complete transform Texture to Dither!!");
22 }
