public sealed class AssetListAttribute : Attribute, _Attribute

AssetLists is used on lists and arrays and single elements of unity types, and replaces the default list drawer with a list of all possible assets with the specified filter.

Use this to both filter and include or exclude assets from a list or an array, without navigating the project window.

Remarks

Asset lists works on all asset types such as materials, scriptable objects, prefabs, custom components, audio, textures etc, and does also show inherited types.

Example

The following example will display an asset list of all prefabs located in the project window.

public class AssetListExamples : MonoBehaviour
{
    [InfoBox("The AssetList attribute work on both lists of UnityEngine.Object types and UnityEngine.Object types, but have different behaviour.")]
    [AssetList]
    [InlineEditor(InlineEditorModes.LargePreview)]
    public GameObject Prefab;

    [AssetList]
    public List<PlaceableObject> PlaceableObjects;

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

    [AssetList(AutoPopulate = true)]
    public List<PlaceableObject> PlaceableObjectsAutoPopulated;

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

    [AssetList(AssetNamePrefix = "Rock")]
    public List<GameObject> PrefabsStartingWithRock;

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

    [AssetList(Tags = "MyTagA, MyTabB", Path = "/Plugins/Sirenix/")]
    public List<GameObject> GameObjectsWithTag;

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

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

    [InfoBox("Use a method as a custom filter for the asset list.")]
    [AssetList(CustomFilterMethod = "HasRigidbodyComponent")]
    public List<GameObject> MyRigidbodyPrefabs;

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