Making a simple steam connection identifier (Learning Lua)

Hello soo i’m wondering why am i getting an error while debugging this code? also if there’s anything wrong, would anybody care to explain?

I know there are plentys out there but i’m trying to learn lua soo … yeah.

Also, am i supposed to register the event? if so, why is that?

addEventHandler('playerConnecting', function(playerName, setKickReason))    
    local identifySteam = string.sub(GetPlayerIdentifiers(source), 1, 5) -- Grabbing the 5 letters from the steam id "steam".
    
    if identifySteam == steam then -- Comparing the 5 letters with the word steam and if they are correct then i'm allowing the user to connect.
      deferrals.done() 
    else
      deferrals.done("You're not using a steam account.") -- If they don't match, i'm kicking him out.
    end 
  end

Apparently if you call out deferrals.done() it’s supposed to allow the connection but if you put in a label inside the parentesis it’ll kick the user.

I’ve done this code with the wiki, is this info accurate?

AddEventHandler not addEventHandler, you are also missing the deferrals parameter in the function. You are also comparing identifySteam to a nil variable, it should be identifySteam == "steam".

Alright @Nick78111 i fixed it.

It looks like this but now it’s failing to load in?

AddEventHandler('playerConnecting', function(playerName, deferrals))    
    local identifySteam = string.sub(GetPlayerIdentifiers(source), 1, 5)
    
    if identifySteam == "steam" then
      deferrals.done() 
    else
      deferrals.done("You're not using a steam account.") 
    end 
  end

Should be function(playerName, setKickReason, deferrals)

You also have to call deferalls.defer()

6 
AddEventHandler('playerConnecting', function(playerName, setKickReason, deferrals))
    local identifySteam = string.sub(GetPlayerIdentifiers(source), 1, 5)
    
    if identifySteam == "steam" then
      deferrals.done() 
    else
      deferrals.defer("You're not using a steam account.") 
    end 
  end

Still getting unexpected symbol near ) line 1 but i’m not sure what is wrong.

Do i have to register the event?

7

Okay for some reason i had to close the parenthesis when the function ended (at the last end).

Yeah that’s how it works. It’s meant to be like that.

9 
AddEventHandler('playerConnecting', function(playerName, setKickReason, deferrals)
    local identifySteam = string.sub(GetPlayerIdentifiers(source)[1], 1, 5)
    
    if identifySteam == 'steam' then
        deferrals.done()
    else
        deferrals.defer('You are not using a steam account.')
    end
end)

Something like that, but I am not experienced with deferrals.

You probably want to defer the connection first, wait a tick and then check if it’s done or has an error:

AddEventHandler('playerConnecting', function(playerName, setKickReason, deferrals)
    -- Tell the system we want to defer this connection
    defferals.defer()

    -- Wait for the next server tick, this is required.
    Citizen.Wait(0)

    local identifySteam = string.sub(GetPlayerIdentifiers(source)[1], 1, 5)
    
    if identifySteam == 'steam' then
        -- We have a steam id, let the player connect.
        deferrals.done()
    else
        -- We have not found a steam id, tell the user that it failed to fetch a steam id.
        deferrals.done('You are not using a steam account.')
    end
end)

This is really old but you spelt deferrals wrong once :stuck_out_tongue:
