Print text for for team issue

[KFord]

Hello i am creating a Undercover job and i want text above the players head that is using the job "Undercover" this is what i have so far only simple.

function DrawUndercoverIndicator(ply)
	local zOffset = 50
	local x = ply:GetPos().x			
	local y = ply:GetPos().y			
	local z = ply:GetPos().z			
	local pos = Vector(x,y,z+zOffset)	
	local pos2d = pos:ToScreen()		
	draw.DrawText("Undercover","Default",pos2d.x,pos2d.y,Color(25, 25, 170, 255),TEXT_ALIGN_CENTER)
end

function LoopThroughPlayers()
	for k,v in(player.GetAll()) do
		if ply:Team() == allowedTeam then // This is Team Undercover
			DrawUndercoverIndicator(v)
		end
	end
end

hook.Add("HUDPaint", "LoopThroughPlayers", LoopThroughPlayers)

how do i make it so the text only apears for a list of allowed teams for example. :ohno:

Thanks guys sorry for probably poor coding

[MysteryPancake]

local allowed_teams = {
   SOME_TEAM = true,
   ANOTHER_TEAM = true,
   YOU_GET_THE_IDEA = true,
}

local function LoopThroughPlayers()
	for k,v in(player.GetAll()) do
		if allowed_teams[ ply:Team() ] then // This is Team Undercover
			DrawUndercoverIndicator(v)
		end
	end
end

Also, your code is alright but please make your functions local

Also, this:

function DrawUndercoverIndicator(ply)
	local zOffset = 50
	local x = ply:GetPos().x			
	local y = ply:GetPos().y			
	local z = ply:GetPos().z			
	local pos = Vector(x,y,z+zOffset)	
	local pos2d = pos:ToScreen()		
	draw.DrawText("Undercover","Default",pos2d.x,pos2d.y,Color(25, 25, 170, 255),TEXT_ALIGN_CENTER)
end

Can be simplified into this:

function DrawUndercoverIndicator(ply)
	local zOffset = 50		
	local pos = ply:GetPos()
	pos.z = pos.z + zOffset
	local pos2d = pos:ToScreen()		
	draw.DrawText("Undercover","Default",pos2d.x,pos2d.y,Color(25, 25, 170, 255),TEXT_ALIGN_CENTER)
end
