    static function DoToggle() {
        var activeGOs: Object[] =
            Selection.GetFiltered(
                GameObject,
                SelectionMode.Editable | SelectionMode.TopLevel);

for (var obj in activeGOs) var activeGO = obj as GameObject; activeGO.SetActive(!activeGO.activeSelf); } }
