【小工具】Unity批量删除物体上引用丢失的脚本

介绍

Unity批量删除物体上引用丢失的脚本

使用场景

当在外部导入资源时会造成物体上挂载的脚本引用丢失，一个个删除比较麻烦，可以借用这个工具快速实现

工具原理

继承EditorWindow绘制一个自定义的编辑器窗口
加载Assets目录下所有预制体
- 获取其所有子物体的Component组件
- 如果组件为Null则表示丢失
- 将丢失的物体加入待清理列表
遍历待清理列表，通过**GameObjectUtility.RemoveMonoBehavioursWithMissingScript(obj);**进行清理；

使用API

高亮显示资源并选中

 EditorGUIUtility.PingObject(selectTarget);Selection.activeObject = selectTarget;

获取指定文件夹下指定类型得资源路径

Directory.GetFiles("Assets","*.prefab",SearchOption.AllDirectories);

显示进度条

if(EditorUtility.DisplayCancelableProgressBar("Title","信息",Rage(0,1)))
{EditorUtility.ClearProgressBar();break;
}

移除丢失脚本的组件

GameObjectUtility.RemoveMonoBehavioursWithMissingScript(gamoObjList[i]);

编辑器下加载资源、保存资源

AssetDatabase.LoadAssetAtPath<GameObject>(paths[i]);AssetDatabase.SaveAssets();
AssetDatabase.Refresh();
