local kepernyoX, kepernyoY = guiGetScreenSize()
addEventHandler(\"onClientRender\", getRootElement(),
        function()
                dxDrawRectangle((kepernyoX / 2) - (400 / 2), (kepernyoY / 2) - (200 / 2), 400, 200, tocolor(60, 60, 60, 150))
        end
)
 A konzolba ezt írja:.
world_anim\\clint.lua:1: attempt to call gloabl \'guiGetScreenSize\' <a nil value>
Mi a gond?  :question:
