dxDrawTextOnElement, dxDrawRectangle3D

[TrickyTommy]

Hi!
I am trying to make two things on my server:
    -license plates above cars, and rectangles above them too.
    -player nametags, and my nametag should not be visible for myself.
I have problems with both:
-the rectrangle is not getting drawn above the car
-i don't know how sould i make my nametag not visible for myself.

Current progress:
 

function Draw()

	local vehs = getElementsByType("vehicle")
	
	for k,v in ipairs(vehs) do
		dxDrawTextOnElement (v, getVehiclePlateText(v), 0.75, _, _, _, _, _, 2)
		local x, y, z = getElementPosition (v)
		dxDrawRectangle3D (x+1, y+1, z+1, 100, 25, tocolor(255, 0, 0, 0))
	end
	
	local players = getElementsByType("player")
	
	for k,v in ipairs(players) do
		dxDrawTextOnElement (v, getPlayerName(v), _, _, _, _, _, _, 1)
	end
	
end
addEventHandler ("onClientRender", getRootElement(), Draw)

try that, If doesn't work perfectly screenshot please.

	local vehs = getElementsByType("vehicle")
	
	for k,v in ipairs(vehs) do
		dxDrawTextOnElement (v, getVehiclePlateText(v), 0.75, _, _, _, _, _, 2)
		local x, y, z = getElementPosition (v)
    	local width = 100
    	local hight = 50
		dxDrawRectangle3D (x, y, z+, width, hight, tocolor(255, 0, 0, 0))
	end
	
	local players = getElementsByType("player")
	
	for k,v in ipairs(players) do
    	if v ~= localPlayer then
			dxDrawTextOnElement (v, getPlayerName(v), _, _, _, _, _, _, 1)
        end
	end
	
end
addEventHandler ("onClientRender", getRootElement(), Draw)

think the solution for the nametag works, yet the rectangle is not visible....

[_DrXenon]

The rectangle's alpha is set to 0.

dxDrawRectangle3D (x, y, z+, width, hight, tocolor(255, 0, 0, 0))

change the tocolor arg into this; tocolor(255,0,0,255).

[TrickyTommy]

as i know, the first one is the argument for alpha.
anyways, still not working
 

dxDrawRectangle3D (x, y, z+1, 100, 50, tocolor(255, 255, 255, 255))

did you put the source code of the useful functions?

[Mr.Loki]

I modified the custom function a bit... but this is what it does. I hope this helps.

Also added another arg to set the background colour or hide it.
