public static Object[] GetFiltered (Type type, SelectionMode mode);


type このタイプのオブジェクトのみが取得されます
mode さらに Selection を絞り込むためのオプション



For a selected GameObject that has multiple Components of type, only the first one will be included in the results.
If type is a subclass of Component or GameObject the full SelectionMode is supported.
If type does not subclass from Component or GameObject (eg. Mesh or ScriptableObject) only SelectionMode.ExcludePrefab and SelectionMode.Editable are supported.

using UnityEngine;
using UnityEditor;

class ToggleActive : ScriptableObject { [MenuItem("Example/Toggle Active of Selected %i")] static void DoToggle() { Object[] activeGOs = Selection.GetFiltered( typeof(GameObject), SelectionMode.Editable | SelectionMode.TopLevel);

foreach (GameObject obj in activeGOs) { obj.SetActive(!obj.activeSelf); } } }
