Selection.GetFiltered

Parameters

Description

Returns the current selection filtered by type and mode.

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.

    [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);
        }
    }
