My first library.. Need help.

[sackcreator54]

Hello. I am making a clientside library. Here's my code:

local vx
vx = {}
function vx.roundedbox( w, h )
	draw.RoundedBox(0, 0, 0, w, h, Color(30, 30, 30, 200))
end

I have this file AddCSLuaFile'd and included, and when I go put

vx.roundedbox(50, 50)

in my HUDDraw code, it gives me errors saying attempt to index global 'vx' (a nil value)

Still can't figure it out :l

remove the "local vx" at the top.

:o idk how that fixed it.. but it did.. Thank you :D

Yeah, when you call the function it doesn't know what vx is.

Because vx was a local table (usable in that file.), but when you remove local it becomes a global table (usable anywhere.)

Okay, so now, it works, but now I want to define a **[B][U]serverside[/U][/B]** library. The code above was clientside. Here's my code:

vx = {}
local cmds = {}

function vx.AddChatCmd( cmdname )
	table.insert(cmds, cmdname)
end

function ChatCmds( ply, text, public )
	for _, v in pairs(cmds) do
		if (string.sub(text, 1, string.len(v)) == v) then
			 print("You said " ..v.. "!")
			 return(true)
		end
	end
end
hook.Add( "PlayerSay", "AllCmds", ChatCmds )

I tried running

vx:AddChatCmd("/hi")

and I get "attempt to index global 'vx' (a nil value)"

vx.AddChatCmd not vx:AddChatCmd (wrong operator)

I fixed that.

sv_plugin.lua:

vx.AddChatCmd("/hi")

Make sure your vx table is declared before you run the function.

Usually this is because one file is included before another.

[sackcreator54]

For some reason, when i put vx.AddChatCmd("/hi") in the library file under function vx.AddChatCmd( cmdname ), it works, I type "/hi" in game, and it prints "You said /hi!"

Hmm..
