Unity-工具-查找丢失资源的Objects
- Resources.FindObjectsOfTypeAll
This function can return any type of Unity object that is loaded, including game objects, prefabs, materials, meshes, textures, etc. It will also list internal stuff, therefore please be extra careful the way you handle the returned objects. Contrary to Object.FindObjectsOfType this function will also list disabled objects.
public SerializedProperty GetIterator();
返回SerializedProperty类
objectReferenceValue 参数：Object索引的相关obj

AssetDatabase-FindAssets
filter中可以包括名称、标签或者类型（类名称）
Name：
名称通过空格隔开当成一个独立的名字来搜索。比如"Texture Player"，隔开的字段可以用来筛选，Texture和Player都可以进行查找
Labels：Assets可以通过labels附加来进行查找，Assets可以通过关键字'l:'加一个label来进行查找。
Types：在资源类型前加关键字't:'，来过滤字符串中包含多个类型。
Types(包括以下):
Prefab
Object
Shader
Material
Texture
Font
Flare
Cubemap
public static string[] FindAssets(string filter);
public static string[] FindAssets(string filter, string[] searchInFolders);
当使用带路径的重载的时候，路径是一个字符串数组，并且这个路径是"Assets"这样的相对路径，此方法会遍历路径下全部文件包括，目标文件下的全部子文件。
SerializedObject and SerializedProperty are classes for editing properties on objects in a completely generic way that automatically handles undo and styling UI for prefabs.
SerializedObject is used in conjunction with SerializedProperty and Editor classes.
这个版本将原本的函数进一步抽象，将简单的方法暴露，方便编程人员的使用
提高资源检查的和复用性，在Match方法中，如果是场景，通过EditorSceneManager.OpenScene打开场景，通过此方法的返回值scene，调用方法GetRootGameObjects，拿到场景中的根GameObjects，在遍历Root下面的全部GameObjects
如果不是Scene文件，是其他类型的资产，直接使用AssetDatabase.LoadAllAssetsAtPath方法，拿到全部资产，将全部资产遍历，使用序列化的方式遍历每个资产。
