Unity查找Editor下Project视图中特定的资源

 [MenuItem("Tools/Check Text Count")]
 public static void CheckText ()
 {
     //查找指定路径下指定类型的所有资源，返回的是资源GUID
     string[] guids = AssetDatabase.FindAssets ("t:GameObject", new string[] { "Assets/Resources/UI" });
     //从GUID获得资源所在路径
     List<string> paths = new List<string> ();
     guids.ToList ().ForEach (m => paths.Add (AssetDatabase.GUIDToAssetPath (m)));
     //从路径获得该资源
     List<GameObject> objs = new List<GameObject> ();
     paths.ForEach (p => objs.Add (AssetDatabase.LoadAssetAtPath (p, typeof (GameObject)) as GameObject));
     //下面就可以对该资源做任何你想要的操作了，如查找已丢失的脚本、检查赋值命名等，这里查找所有的Text组件个数
     List<Text> texts = new List<Text> ();
     objs.ForEach (o => texts.AddRange (o.GetComponentsInChildren<Text> (true)));
     Debug.Log ("Text count:" + texts.Count);
 }

查找到你想要处理的资源后可以进行各种自定操作了，可参考以下博主的示例：

其中删除missing的脚本很有用哦，单独Mark一下：

 [MenuItem("Edit/Cleanup Missing Scripts")]
  static void CleanupMissingScripts ()
  {
      for(int i = ; i < Selection.gameObjects.Length; i++)
      {
          var gameObject = Selection.gameObjects[i];
 
          // We must use the GetComponents array to actually detect missing components
          var components = gameObject.GetComponents<Component>();
 
          // Create a serialized object so that we can edit the component list
          var serializedObject = new SerializedObject(gameObject);
          // Find the component list property
          var prop = serializedObject.FindProperty("m_Component");
 
          // Track how many components we've removed
          int r = ;
 
          // Iterate over all components
          for(int j = ; j < components.Length; j++)
          {
              // Check if the ref is null
              if(components[j] == null)
              {
                  // If so, remove from the serialized component array
                  prop.DeleteArrayElementAtIndex(j-r);
                  // Increment removed count
                  r++;
              }
          }
 
          // Apply our changes to the game object
          serializedObject.ApplyModifiedProperties();
          //这一行一定要加！！！
          EditorUtility.SetDirty(gameObject);
      }
  }
