Showing a part of hud on holding a button

[logimy]

Hello, Facepunch!
I had encountered with a very simple and even funny problem, but i don't have any idea how to solve it. (I'm not so smart though) :)

I'm making a tiny custom hud addon for my DarkRP server. I want to hide a small part of it and make it shown when player hold "alt" button for example.
I've tried [URL="http://wiki.garrysmod.com/page/Player/KeyDown"]this[/URL], but i don't actually find out how to use it properly.

SS of hud (with highlighted desired section) and code of that part:

local function PlayerInfo()

	-- Values
	local Salary_Value	= "$"..formatNumber(LocalPlayer():getDarkRPVar("salary")	or 0)
	local Money_Value	= "$"..formatNumber(LocalPlayer():getDarkRPVar("money") 	or 0)
	local Job_Value		= LocalPlayer():getDarkRPVar("job") or ""

	local Box_Center	= HUDSettings.Width / 10
	local Box_TopSize	= (HUDSettings.Width / 2 - 40) / 1.5
	local Hud_Half		= HUDSettings.Width / 2
		
	
	-- W
	
	draw.DrawText(" Кошелек: "..Money_Value, "rTCB_BebasNeue_mid", HUDSettings.PosX+5 + 1 + 320, HUDSettings.PosY+274 + 1, Color(0,0,0,255), 0)
	draw.DrawText(" Кошелек: "..Money_Value, "rTCB_BebasNeue_mid", HUDSettings.PosX+5 + 2 + 320, HUDSettings.PosY+274, Color(255,255,255,255), 0)

	-- S
	draw.DrawText(" Жалование: "..Salary_Value, "rTCB_BebasNeue_mid", HUDSettings.PosX+5 + 1 + 320, HUDSettings.PosY+294 + 1, Color(0,0,0,255), 0)
	draw.DrawText(" Жалование: "..Salary_Value, "rTCB_BebasNeue_mid", HUDSettings.PosX+5 + 2 + 320, HUDSettings.PosY+294, Color(255,255,255,255), 0)
	
	-- J

	draw.DrawText(" Статус: "..Job_Value, "rTCB_BebasNeue_mid", HUDSettings.PosX+5 + 1 + 320, HUDSettings.PosY+314 + 1, Color(0,0,0,255), 0)
	draw.DrawText(" Статус: "..Job_Value, "rTCB_BebasNeue_mid", HUDSettings.PosX+5 + 2 + 320, HUDSettings.PosY+314, Color(255,255,255,255), 0)

end

you can use i assume use something like

for k,v in pairs(player.GetAll()) do
    if ply:KeyDown(KEY_ALT) then return true else return false
    -- hud code

not guaranteeing you anything, i have never made a hud.

Try this;

-- Inside your HUDPaint
if LocalPlayer:KeyDown(KEY_LALT) then -- Check for left alt
    PlayerInfo()
end

local ply = LocalPlayer()

if ply:KeyDown(KEY_ALT) then
    -- Hud Code
else return end

[ERROR] addons/darkrpmodification/lua/darkrp_modules/gmodlog_hud_v1/cl_hud.lua:574: attempt to index global 'LocalPlayer' (a function value)

I've edited last post for right error.
I have this:

-- HUDPaint
local function DrawTCBHud()

	-- Custom
	Base()
	
    if LocalPlayer:KeyDown(KEY_LALT) then -- Check for left alt
    PlayerInfo()
	end
	
	-- Elements
	ElementHealth()

	if HUDElements.Armor then
		ElementArmor()
	end

	if HUDElements.Hunger then
		ElementHunger()
	end

	if HUDElements.Stamina then
		ElementStamina()
	end

	-- Default
	Agenda()
	DrawVoiceChat()
	LockDown()
	
	Arrested()
	AdminTell()
	
	DrawEntityDisplay()

end
hook.Add("HUDPaint", "DrawTCBHud", DrawTCBHud)

You need LocalPlayer():KeyDown(KEY_LALT);, not LocalPlayer. It's a function, not a variable. However, Jack got it wrong too :v:
