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);

      }

  }
