unity批量修改AssetBundleName与Variant

批量修改指定路径下的资源的AssetBundleName与Variant。

脚本代码如下：

 using UnityEditor;
 using System.IO;
 /// <summary>
 /// AlterAssetBundle类为修改批量修改AssetBundle的Name与Variant的编辑器窗口

         AlterAssetBundle window = (AlterAssetBundle)EditorWindow.GetWindow(typeof(AlterAssetBundle), false, "批量修改AssetBundle");
         window.Show();

     }

     //输入文字的内容
     private string Path = "Assets/Resources/", AssetBundleName="", Variant="";
