Assets Only Attribute特性有兩類

• AssetsOnly： 點擊需要序列化的資源字段時，在出現的彈窗中只有Project中的資源文件，不會出現Hierachy（場景）的資源
• SceneObjectsOnly： 點擊需要序列化的資源字段時，在出現的彈窗中只有Hierachy中的資源文件，不會出現Project中的資源
  注意：例如：預制體等資源在Scene或者Project中都含有，出現的彈窗中也都會含有對應的資源

選中場景中的資源

    [SceneObjectsOnly]
    public List<GameObject> onlySceneObjectList;

    [SceneObjectsOnly]
    public GameObject someSceneObject;

    [SceneObjectsOnly]
    public MeshRenderer someMeshRendererInScene;

選中工程中的資源

    [AssetsOnly]
    public List<GameObject> assetsOnlyPrefabList;

    [AssetsOnly]
    public GameObject ssetsOnlyPrefab;

    [AssetsOnly]
    public Material assetsOnlyMaterial;

    [AssetsOnly]
    public MeshRenderer someMeshRendererOnPrefab;

    [AssetsOnly]
    public Material MaterialAsset;

    [AssetsOnly]
    public MeshRenderer SomeMeshRendererOnPrefab;

    [SceneObjectsOnly]
