Problem with dxDrawTextOnElement

[ivan8065]

Hello, I was trying to make script that would show the name of bus stop in front of bus.

 

I started by trying this example from wiki:

local randomPed = createPed(285, 2476.91406, -1665.31799, 13.32435)

addEventHandler("onClientRender", getRootElement(), 
function()
	dxDrawTextOnElement(randomPed, "SWATTEAM Officer", 1, 20, 0, 0, 255, 255, 1, "pricedown")
end)

but it throws me this error: client.lua:5 attempt to call global 'dxDrawTextOnElement' (a nil value)

 

Was the function removed from MTA or what can be problem please? Thank you for reply.

No, it's just that Useful functions are functions made by the community and that are not built-in into MTA.

To use them, you have to copy the function code first. And then you can call it (the function source code is lower on the wiki page: https://wiki.multitheftauto.com/wiki/DxDrawTextOnElement

local randomPed = createPed(285, 2476.91406, -1665.31799, 13.32435)

addEventHandler("onClientRender", getRootElement(), 
function()
	dxDrawTextOnElement(randomPed, "SWATTEAM Officer", 1, 20, 0, 0, 255, 255, 1, "pricedown")
end)

-- Function source copied from wiki https://wiki.multitheftauto.com/wiki/DxDrawTextOnElement
function dxDrawTextOnElement(TheElement,text,height,distance,R,G,B,alpha,size,font,...)
	local x, y, z = getElementPosition(TheElement)
	local x2, y2, z2 = getCameraMatrix()
	local distance = distance or 20
	local height = height or 1

	if (isLineOfSightClear(x, y, z+2, x2, y2, z2, ...)) then
		local sx, sy = getScreenFromWorldPosition(x, y, z+height)
		if(sx) and (sy) then
			local distanceBetweenPoints = getDistanceBetweenPoints3D(x, y, z, x2, y2, z2)
			if(distanceBetweenPoints < distance) then
				dxDrawText(text, sx+2, sy+2, sx, sy, tocolor(R or 255, G or 255, B or 255, alpha or 255), (size or 1)-(distanceBetweenPoints / distance), font or "arial", "center", "center")
			end
		end
	end
end

^ Like this, your script will work
