menu_item_1->setPosition(Point(visibleSize.width/2,(visibleSize.height/5)*4));
menu_item_2->setPosition(Point(visibleSize.width/2,(visibleSize.height/5)*3));
menu_item_3->setPosition(Point(visibleSize.width/2,(visibleSize.height/5)*2));
menu_item_4->setPosition(Point(visibleSize.width/2,(visibleSize.height/5)*1));
