Asset List Attribute特性：用于列表和數組以及Unity type的單個元素，并將默認列表Drop替換為具有指定過濾器的所有可能資產的列表。使用此選項可以過濾并在列表或數組中包含或排除資產，而無需導航項目窗口。

AssetList：創建一個指定類型的列表

    [AssetList]
    [PreviewField(70, ObjectFieldAlignment.Center)]
    public Texture2D SingleObject;

【Path】根據指定篩選資源的路徑

    [AssetList(Path = "Plugins/Sirenix/")]
    public UnityEngine.Object Object;

如果是List，將以列表的形式表示出來,但是只有在選中時，才會被添加到List中

    [AssetList(Path = "/Plugins/Sirenix/")]
    public List<ScriptableObject> AssetList;

【AutoPopulate】符合規則的自動添加到List中

    [AssetList(AutoPopulate = true)]//設置為true則自動填充符合規則的資源,false為只顯示不填充
    public List<MeshRenderer> AutoPopulatedWhenInspected;

【LayerNames】也可以指定layer層過濾

    [AssetList(LayerNames = "MyLayerName")]//
    public GameObject[] AllPrefabsWithLayerName;

【AssetNamePrefix】以資源名稱的前綴作為篩選條件

    [AssetList(AssetNamePrefix = "前綴")]
    [FoldoutGroup("過濾后的AssetLists")]
    public List<GameObject> PrefabsStartingWithPrefix;

【Tags】以資源的tag作為篩選條件，可用，符號分隔多個Tag

    [AssetList(Tags = "TagA,TagB",Path = "/TutorialAsset")]
    public List<GameObject> GameObjectsWithTag;

【CustomFilterMethod】自定義過濾函數

    [AssetList(CustomFilterMethod = "HasRigidbodyComponent")]
    public List<GameObject> MyRigidbodyPrefabs;

    private bool HasRigidbodyComponent(GameObject obj)
    {
        return obj.GetComponent<Rigidbody>() != null;
    }

public class AssetListAttributeExample : MonoBehaviour
{
    [AssetList]
    [PreviewField(70, ObjectFieldAlignment.Center)]
    public Texture2D SingleObject;

    [AssetList(Path = "Plugins/Sirenix/")]
    public UnityEngine.Object Object;

    [AssetList(Path = "/Plugins/Sirenix/")]
    public List<ScriptableObject> AssetList;

    [AssetList(AutoPopulate = true)]//設置為true則自動填充符合規則的資源,false為只顯示不填充
    public List<MeshRenderer> AutoPopulatedWhenInspected;

    [AssetList(LayerNames = "MyLayerName")]//
    public GameObject[] AllPrefabsWithLayerName;

    [AssetList(AssetNamePrefix = "前綴")]
    [FoldoutGroup("過濾后的AssetLists")]
    public List<GameObject> PrefabsStartingWithPrefix;

    [AssetList(Tags = "TagA,TagB",Path = "/TutorialAsset")]
    public List<GameObject> GameObjectsWithTag;

    [AssetList(CustomFilterMethod = "HasRigidbodyComponent")]
    public List<GameObject> MyRigidbodyPrefabs;

    private bool HasRigidbodyComponent(GameObject obj)
    {
        return obj.GetComponent<Rigidbody>() != null;
    }
}
