Assets Only Attribute特性有两类

• AssetsOnly： 点击需要序列化的资源字段时，在出现的弹窗中只有Project中的资源文件，不会出现Hierachy（场景）的资源
• SceneObjectsOnly： 点击需要序列化的资源字段时，在出现的弹窗中只有Hierachy中的资源文件，不会出现Project中的资源
  注意：例如：预制体等资源在Scene或者Project中都含有，出现的弹窗中也都会含有对应的资源

选中场景中的资源

    [SceneObjectsOnly]
    public List<GameObject> onlySceneObjectList;

    [SceneObjectsOnly]
    public GameObject someSceneObject;

    [SceneObjectsOnly]
    public MeshRenderer someMeshRendererInScene;

选中工程中的资源

    [AssetsOnly]
    public List<GameObject> assetsOnlyPrefabList;

    [AssetsOnly]
    public GameObject ssetsOnlyPrefab;

    [AssetsOnly]
    public Material assetsOnlyMaterial;

    [AssetsOnly]
    public MeshRenderer someMeshRendererOnPrefab;

完整示例代码

using Sirenix.OdinInspector;
