Garry's Mod scripting - HUDPaint not called?

Hello, I'm new to Garry's Mod (bought it couple of days ago)

Wrote up a simple script for testing;

Code:

local function Meatgrinder()
  print('hi');
  draw.SimpleTextOutlined("Hello World", "Default", 20, 20, Color(255, 255, 255), TEXT_ALIGN_CENTER, TEXT_ALIGN_CENTER, 1, Color(0, 0, 0));
end

hook.Remove("HUDPaint", "Meatgrinder");
hook.Add("HUDPaint", "Meatgrinder", Meatgrinder);

I load it ingame in the console with lua_openscript however, after that nothing happens.

"hi" does not print to console, "Hello World" does not print on screen.

What am I doing wrong?

Thanks for help

If I hook "Think" it gets called, but LocalPlayer() gives me error "attempt to call global 'LocalPlayer' (a nil value)" is this because I'm playing on a local server?

Try typing:
sv_allowcslua 1
in console if it is your server.
Probably won't work though, I'm a noob at this stuff.

Try setting players to 2 before running the local server.
You should run lua_openscript_cl instead of lua_openscript if that doesnt work try running sv_allowcslua 1 and then lua_openscript_cl [filepathhere ] again.
I have no idea if the ";"s would cause problems but I dont think so.

BTW: Why are you running hook.Remove?

Thanks to both of you for your help.

Making a 2 player game and setting sv_allowcslua 1 helped!

The ";" does not cause a problem. It's optional in LUA, like in JavaScript. I'm just putting it because I'm used to it from C++ and PHP

To remove my old hook before adding new. Probably not necessary but made sense to me

Edit:

Everything WAS working fine, but now after playing around a bit, testing I've started getting this really weird(?) error, here's script now:

Code:

local function hThink()
  local Me;
  Me = LocalPlayer();
end

hook.Add("Think", "novThink", hThink);

Error

Code:

[ERROR] lua/novo.lua:3: attempt to call global 'LocalPlayer' (a nil value)
  1. v - lua/novo.lua:3
   2. unknown - lua/includes/modules/hook.lua:82

Are you sure you are running lua_openscript_cl?

That was the problem! Thanks.
Don't know how I forgot that :'(

Code:

hook.Remove("HUDPaint", "Meatgrinder");
hook.Add("HUDPaint", "Meatgrinder", Meatgrinder);

Why are you removing a non existant hook then adding it?

Code:

  local Me;
  Me = LocalPlayer();

Why not just do

Code:

local Me = LocalPlayer();

I don't understand you.

I cut it from a longer function before pasting, but yeah, that would've made more sense in the context :P
