Solved Sign Bug...

Hello,
I have a problem... When a player arrives at the server, the sign adds a player but when he leaves, the sign does not removed the player...

The plugin Main:

PHP:

<?php

namespace HB;

use pocketmine\Server;
use pocketmine\Player;
use pocketmine\plugin\PluginBase;
use pocketmine\event\Listener;
use pocketmine\level\Level;
use pocketmine\tile\Sign;
use pocketmine\block\Block;
use pocketmine\item\Item;
use pocketmine\math\Vector3;
use pocketmine\entity\Entity;

use pocketmine\event\player\PlayerJoinEvent;
use pocketmine\event\player\PlayerQuitEvent

use pocketmine\scheduler\Task;
use HB\{SignTask, TaskEnd, TaskInv, TaskPvP};

class Main extends PluginBase implements Listener{

  public $status = array();

  public $player = array();

  public function onEnable(){
    $this->getServer()->getPluginManager()->registerEvents($this, $this);
    $this->getLogger()->info("HotBlock Enabled !");
    if(!isset($this->status['HB'])){
      $this->status['HB'] = 0;
    }
    $this->getServer()->getScheduler()->scheduleRepeatingTask(new SignTask($this), 20 * 3);
  }
 
  public function onPlayerJoin(PlayerJoinEvent $event){
    $player = $event->getPlayer();
    array_push($this->player, $player->getName());
  }

  public function onPlayerQuit(PlayerQuitEvent $event){ //Marche pas.
    $player = $event->getPlayer();
    if(isset($this->player[$player->getName()])){
      unset($this->player[$player->getName()]);
      $player->sendMessage("LEFT");
    }
  }
 
  public function SignTask(){
    $tile = $this->getServer()->getLevelByName("world")->getTile(new Vector3(133, 6, 128));
    if($tile instanceof Sign){
      if($this->status["HB"] == 0){
        $tile->setText("[HotBlock]", "Map : End", "Players : ".count($this->player)." / 15", "TEST");
      }else{
        $tile->setText("[HotBlock]", "Map : End", "Players : ".count($this->player)." / 15", "In Game...");
      }
    }
  }
}

The plugin Task:

PHP:

<?php

namespace HB;

use pocketmine\scheduler\PluginTask;
use pocketmine\math\Vector3;
use pocketmine\tile\Sign as SignTile;
use HB\Main;

class SignTask extends PluginTask{

  public function __construct(Main $owner){
    parent::__construct($owner);
    $this->owner = $owner;
  }
 
  public function onRun($currentTick){
    $this->getOwner()->SignTask();
  }
}

Thanks you for your help.

You need the key when using unset(). Use

PHP:

$array[array_search($name, $array)];

While $array is your array, and $name is the playername. array_search() returns the key.

But... why don't you simply count all online players?

PHP:

  $player = $event->getPlayer();
  $name = $player->getName();
  $p1 = array_search($name,$this->players);
               unset($this->players[$p1]);
//For unset solution..

Hello,
I do not count online players because this code is not the real... (in truth, it's the players on arenas but I simplified the code).
Thanks, I'll try !
I'll keep you informed.
