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 = 0; 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 = 0;
         
         // Iterate over all components
         for(int j = 0; 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);
     }
 }
