"attempt to index global 'chat' (a nil value)"

I want to use chat.AddText for some things in an script i’m writing, however for some reason no matter what I it just shows me this error:


[ERROR] lua/pointshop/items/sniper/weapon_zm_rifle_ps.lua:5: attempt to index global 'chat' (a nil value)
  1. OnBuy - lua/pointshop/items/sniper/weapon_zm_rifle_ps.lua:5
   2. PS_BuyItem - lua/pointshop/sv_player_extension.lua:254
    3. func - lua/pointshop/sv_init.lua:13
     4. unknown - lua/includes/extensions/net.lua:32

From this code:


function ITEM:OnBuy(ply)
	chat.AddText( Color( 100, 100, 255 ), ply, ", how are you doing?" )
	ply:Give(self.WeaponClass)
end

and/or


concommand.Add( "chattext", function(ply)
	chat.AddText( Color( 100, 100, 255 ), ply, ", how are you doing?" )
end )

Yes, I’ve tried


if CLIENT then

It doesn’t do anything then.

I’m really irritated, because I’ve used chat.AddText before and it worked. What’s wrong now?

Try


if CLIENT then

again.


function ITEM:OnBuy(ply)
    if (CLIENT) then
        chat.AddText( Color( 100, 100, 255 ), ply, ", how are you doing?" )
    else
        ply:Give(self.WeaponClass)
    end
end

are pointshop items even shared?

Dunno if they are but doing your code gives you the weapon so I guess they are not.
What about the concommand.Add? Because it doesn’t work either

#4

ITEM:OnBuy only executes serverside on Pointshop, chat is a clientside library.

You can either go for a simple Player:ChatPrint(string) or if you really need coloured chat text try using something like this.

#5

You are running the code in the server realm (indicated by call stack starting from a serverside file). The Chat library is only available clientside, and calling it serverside will produce an error. A console command added in the server realm will only be called on the server, therefore the same error would also be produced from calling a serverside command that requires a clientside library.

I don’t know much about pointshop, or whether it allows items to define clientside code, but if not, or if you are in a rush, simply network it using the Net library, and call your chat library functions clientside.
