Solved is not the problem

Hi guys,
it's been a while since I stopped her and I just came back and here's the problem

Code:

[13:42:21] [Server thread/CRITICAL]: "Could not pass event 'pocketmine\event\player\PlayerQuitEvent' to 'Skywars-Pro v1.0.0': Undefined index: Praxthisnovcht on Skywars\Main
[13:42:21] [Server thread/NOTICE]: ArrayOutOfBoundsException: "Undefined index: Praxthisnovcht" (E_NOTICE) in "/Skywars-Pro_v1.0.0/src/Skywars/Main" at line 878

PHP:

    public function onPlayerQuit(PlayerQuitEvent $event){
        $player = $event->getPlayer()->getName();
        $p = $event->getPlayer();
            $id = $this->gamePlayers[$player]; # Lines 878 ERROR
            --$this->playersInArena[$id];
            for($n = 1; $n <=4; $n++) {  
                if(isset($this->pod[$id . "-" . $n]) && $this->pod[$id . "-" . $n] == $player) {
                    unset($this->pod[$id . "-" . $n]);
                }
            }
    }

Maybe var_dump the $this->gamePlayers?

PHP:

isset($this->gamePlayers[$player]);

???

Is $player set with a value in the array $gamePlayers ?

That error is caused because $gamePlayers[$player] isn't indexed in the array. I believe.

The problem is that $player isn't in the array. Show the full code so we know what your doing.

i am taking a guess my post fixed it because he liked it

PlayerJoinEvent, PlayerLoginEgent and even PlayerPreLoginEvent may not be fired before PlayerQuitEvent if player quits before he correctly joins. For example, if he joins with an invalid name.
