Custom scoreboard error

[luanooob]

I keep trying to make a scoreboard, because I am trying to learn how to. I know how to get the basic setup but when I make the base of the scoreboard and go in game and press tab it just says nothing.

It says I am “trying to index “GM” a nil value”

i used exactly what was on the wiki but just added my derma panel.

i changed the GM to GAMEMODE and that does get rid of the error but then when I press tab in game nothing shows up.

plz help

Without showing us your code he cannot do anything

This is the file structure...

folder/lua/autorun/scoreboard.lua

I used this code in order to make my scoreboard:

scoreboard = scoreboard or {}

function scoreboard:show()
 local ScoreBoardDerma = vgui.Create("DFrame")
 ScoreBoardDerma:SetSize(750,500)
 ScoreBoardDerma:SetPos(ScrW()/2-325, ScrH()/2-250)
 ScoreBoardDerma:SetTitle("Custom Scoreboard")
 ScoreBoardDerma:SetDraggable(false)
 ScoreBoardDerma:ShowCloseButton(false)
 ScoreBoardDerma.Paint = function()
  draw.RoundedBox(5,0,0,ScoreBoardDerma:GetWide(), ScoreBoardDerma:GetTall(), Color(60,60,60,255))
 end
 local AppList = vgui.Create( "DListView", ScoreBoardDerma )
 AppList:Dock( FILL )
 AppList:SetMultiSelect( false )
 AppList:AddColumn( "Players" )
 AppList:AddColumn( "Kills" )
 function scoreboard:hide()
  -- This is where you hide the scoreboard, such as with Base:Remove()
 end
  --[[ Line painting ]]--
 for _, v in pairs ( player.GetAll() ) do
  local line = playerlist:AddLine( v:Name(), v:Frags(), v:Deaths(), v:Ping() )
  function line:Paint( w, h )
      --Paint the LINEs here
  end
 end
 --[[ Column header painting ]]--
 for _, v in pairs( playerlist.Columns ) do
  function v.Header:Paint( w, h )
      -- Paint the HEADERs here
     end
  v.Header:SetTextColor( Color( 255, 255, 255, 0 ) ) -- Set its text alpha with this in case you paint the text manually
 end
end
function ScoreboardShow()
 scoreboard:show()
end
function ScoreboardHide()
 scoreboard:hide()
end

In the first line, the variable scoreboard..do you let it refer to itself and if not being a table??

If I am going to be completely honest, I do not know. I just used it from the wiki as a template and that was in the little example, I got it from here:

Basic scoreboard creation

[luanooob]

does no one know?

[Trackster]

GM/ScoreboardShow
use this hook and inside that hook do some Category
to create a scoreboard

[luanooob]

So I should use this inside a hook?

Thank fucking god.

Yes you should put it in that hook, kinda like exactly what Trackster said.

GM/ScoreboardShow
use this hook and inside that hook do some Category
to create a scoreboard
