Solved Check if arena is full

command /event [<text>] [<text>]:
    trigger:
        if arg 1 isn't set:
            send "&7/event help"
        if arg 1 is "help":
            player has permission "event.admin":
                send "&8&m---------- &cHELP &8&m----------"
                send "&7/event join"
                send "&7/event leave"
                send "&7soon more"
            else:
                send "&8&m---------- &cHELP &8&m----------"
                send "&7/event join"
                send "&7/event leave"
        if arg 1 is "join":
            if arg 2 isn't set:
                send "&cWrong syntax!"
            else:
                if {ingame.%player%} is true:
                    send "&cYou already in game!"
                else:
                    clear player's inventory
                    teleport player to {spawn.%arg 2%}
                    set {ingame.%player%} to true
                    set {arena.%player%} to arg 2
                    send "&7You joined the game!"
                    wait 1 tick
                    give player stick of knockback 1 named "&fThis is just a normal stick!"                     
        if arg 1 is "leave":
            if arg 2 isn't set:
                send "&cWrong syntax!"
            else:
                if {ingame.%player%} is true:
                    send "&7You left the game!"
                    clear player's inventory
                    delete {arena.%player%}
                    teleport player to {lobby.%arg 2%}
                    set {ingame.%player%} to false

How do I create a player limit on an area. Max of 2 players. If someone joins max of 1 player and if someone leaves then max 2 players again?

Add line 26:

add player to {arenaplayers.%{arena.%player%}%::*}

And add line 34:

remove player from {arenaplayers.%{arena.%player%}%::*}

Then you can check number of players:

if size of {arenaplayers.%arg-2%::*} >= 2:
    send "&cThe arena is full!"
    stop
