newbieShow = show
newbieHead = head
newbieText = text
newbiePosition = element
end

addEventHandler("onClientRender", getRootElement(), 
function()
	if newbieShow == false then return end
	local ax,ay,az = getElementPosition(newbiePosition)
	local x,y = getScreenFromWorldPosition (ax,ay,az)
	local length = dxGetTextWidth(newbieText,1,"default-bold")
	dxDrawRectangle ( x-length/2-screenWidth*0.01,y, screenWidth*0.02+length, screenHeight*0.1, tocolor (33,33,33,100) )
	dxDrawingColorText(newbieHead,x-length/2-screenWidth*0.01,y, x+length/2+screenWidth*0.01, y+screenHeight*0.03, tocolor(22,255,22,120),0.5, 1.1, "default-bold", "center", "center")
