説明

Custom attribute is used to customize the search engine used by the scene search provider.

This sample shows to use the SceneQueryEngineFilter attribute to customize the search engine used by the scene search provider.

The scene search provider allows the user to search for scene objects using custom filters, such as is:prefab prefab:modified, etc.

The following example shows how you can add a property filter lights>=1 to search meshes that are affected but one or more lights.

[SceneQueryEngineFilter("lights", new[] { "=", "!=", "<", ">", "<=", ">=" })]
internal static int? MeshRendererAffectedByLightsSceneFilter(GameObject go)
{
    if (!go.TryGetComponent<MeshRenderer>(out var meshRenderer))
        return null;

    if (!meshRenderer.isVisible)
        return null;

    var lightEffectCount = 0;
    var gp = go.transform.position;
    foreach (var light in Object.FindObjectsOfType<Light>())
    {
        if (!light.isActiveAndEnabled)
            continue;

        var lp = light.transform.position;

        var distance = Vector3.Distance(gp, lp);
        if (distance > light.range)
            continue;

        if (light.type == UnityEngine.LightType.Spot)
        {
            var da = Vector3.Dot(light.transform.forward, lp - gp);
            if (da > Mathf.Deg2Rad * light.spotAngle)
                continue;
        }

        lightEffectCount++;
    }

    return lightEffectCount;
}
