Calling a function on KeyDown

[Swiftone]

Hello guys I was wondering how to call my HUDPaint function when a player is pressing a key? The IsForwardKeyDown function is working I tested it with chatprint but it doesn't seem to call my function key_press() when you hit W. Any help on this would be greatly appreciated!!

ERROR when hitting W:

Hook 'wKeyDownExample' Failed: [gamemodes/hidenseek/gamemode/shared.lua:17] attempt to index global 'draw' (a nil value)
	1. lua/includes/modules/hook.lua:83 (unknown)

My shared.lua:

[lua]

function key_press()
draw.SimpleText( "TEST", "ScoreboardText", ScrW()/2, ScrH()/2, Color(0,128,255,255), TEXT_ALIGN_LEFT)
end
hook.Add("HUDPaint", "key_press", key_press)

local function wKeyDown( ply )

local cmd = ply:GetCurrentCommand()

if cmd:KeyDown( IN_FORWARD ) then
--ply:ChatPrint( "TESTING" )
key_press()
end

end
hook.Add( "Move", "wKeyDownExample", wKeyDown )

[/lua]

did you overwrite the draw library?

Nope, and this is in gmod13 I'm not sure if it makes a difference or not.

[lua]
local drawshit = false

local function key_press()
if not drawshit then return end
draw.SimpleText( "TEST", "ScoreboardText", ScrW()/2, ScrH()/2, Color(0,128,255,255), TEXT_ALIGN_LEFT)
end
hook.Add("HUDPaint", "key_press", key_press)

local function wKeyDown( ply )

local cmd = ply:GetCurrentCommand()

if cmd:KeyDown( IN_FORWARD ) and not drawshit then
drawshit = true
elseif drawshit then
drawshit = false
end

end
hook.Add( "Move", "wKeyDownExample", wKeyDown )
[/lua]

[lua]
local pl = LocalPlayer()

local function DrawKeyPress( )
if pl:KeyDown( IN_FORWARD ) then
draw.SimpleText( "TEST", "ScoreboardText", ScrW()/2, ScrH()/2, Color(0,128,255,255), TEXT_ALIGN_LEFT)
end
end

hook.Add( "HUDPaint", "DrawKeyPress", DrawKeyPress )
[/lua]

Shadow it works tyvm! I see what you did but I am having a hard time following it, the "if not" lines are confusing me, maybe with a fresh mind I can figure it out tomorrow. Feel free to elaborate on it if you don't mind =D

I hope you do know that you're technically adding the same hook server-side since that's the shared.lua file.

Which runs on both client and server.

I'm pretty sure the server doesn't have the table "draw" since it has no actual interface at all, let alone a screen.
