I use this way, best for me.
local screenW,screenH = guiGetScreenSize()
local resW,resH = 1280,720 -- Your resolution (This is mine)
local sW,sH = (screenW/resW), (screenH/resH)
It should look like this then:
local screenW,screenH = guiGetScreenSize()
local resW,resH = 1280,720
local sW,sH = (screenW/resW), (screenH/resH)
addEventHandler("onClientRender", root,
function()
if(getElementData(localPlayer,"loggedIn"))then
dxDrawRectangle(0*sW, 0*sH, 1366*sW, 51*sH, tocolor(0, 0, 0, 255), true)
dxDrawRectangle(0*sW, 0*sH, 1365*sW, 49*sH, tocolor(0, 9, 85, 255), true)
dxDrawRectangle(1365*sW, 130*sH, 1*sW, 0*sH, tocolor(255, 255, 255, 255), true) --...
end
end)
