Can you post the first 10 lines of the cl_init?

[QUOTE=code_gs;46000970]Can you post the first 10 lines of the cl_init?[/QUOTE]

Here is the whole thing, 15 lines.

[lua]

include("shared.lua")

function DrawInformation()
local tr = LocalPlayer():GetEyeTrace();
if not ( tr.Entity:GetClass() == "money_printer_upgrade" ) then return end;

local w = 84
if IsValid( tr.Entity ) and tr.Entity:GetPos():Distance( LocalPlayer():GetPos() ) < 100 then
draw.RoundedBox( 4, ScrW() / 2 - ( w / 2 ), ScrH() / 2 - 40, w, 20, Color( 255, 255, 255, 100 ) );
draw.SimpleText( "Printer Upgrade", "DermaDefault", ScrW() / 2, ScrH() / 2 - 30, color_black, 1, 1 );
end;
end;

function ENT:Draw()
self.Entity:DrawModel()
DrawInformation()
end

hook.Add( "HUDPaint", "KUpgradeNotif", DrawInformation );

[/lua]

Make sure the trace is valid on Line 5.
You could use the same check which is being used on line 8.

This was fixed already... By me

Next time post on the thread you got it from rather then making a new thread for something that has been fixed already.

Quick question though, when you say replace line 5, do you mean delete the 5th line and replace it with this:

[lua] if !IsValid(tr.Entity) or tr.Entity:GetClass() != "money_printer_upgrade" then return end
[/lua]

and what do you mean by "do the same for the printer upgrade?"

My english is not well

[Chibby]

Yes replace line 5, and you have to replace line 5 in the printer upgrade cl_init.lua as well

Thank you!
