PlayerQuitEvent

So i have this code to cancel every Particles task on the player when the player left

PHP:



namespace Wings;

use pocketmine\plugin\PluginBase;
use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\command\ConsoleCommandSender;
use Wings\Tasks\{GreenWing, RedWing, FlameWing};
use pocketmine\Player;

class Main extends PluginBase{

    public $tasks = [];
  //  public $particle1 = array("GreenWing");
 //   public $particle2 = array("RedWing");
 //  public $particle3 = array("FlameWing");

    public function onEnable () : void{
        $this->getServer()->getLogger()->info("§l§aHero§bMC§e>§r§a Wings Enable");
    }

    public function onCommand(CommandSender $sender, Command $cmd, string $label, array $args) : bool{
        if ($cmd == "wing"){
            if(empty($args[0]) || empty($args[1])){
                $sender->sendMessage("§9•§4 Wing Red. §e/wing red <on|off>");
                $sender->sendMessage("§9•§a Wing Green §e/wing green <on|off>");
                $sender->sendMessage("§9•§6 Wing Flame. §e/wing Flame <on|off>");
            return true;
        }
            if(!empty($args[0])){
                switch($args[0]){
                    case "green":
                        if(!$sender->hasPermission("green.wing")){
                            $sender->sendMessage("§l§aHero§bMC§e>§r§c Bạn không có quyền dùng Wing §aGreen");
                        return true;
                    }
                        if($args[1] == "on"){
                        $task = new GreenWing($sender);
                        $this->tasks[$sender->getId()] = $task;
                        $this->getScheduler()->scheduleRepeatingTask($task, 10);
                            $sender->sendMessage("§l§aHero§bMC§e>§r§a Đã bật Wing Green");
                        }
                            if($args[1] == "off"){
                                $task = $this->tasks[$sender->getId()];
                                unset($this->tasks[$sender->getId()]);
                                $task->getHandler()->cancel();
                                $sender->sendMessage("§l§aHero§bMC§e>§r§c Đã tắt Wing §aGreen");
                            }
                    break;
                    case "red":
                        if(!$sender->hasPermission("red.wing")){
                            $sender->sendMessage("§l§aHero§bMC§e>§r§c Bạn không có quyền dùng Wing §4Red");
                        return true;
                    }
                        if($args[1] == "on"){
                        $task = new RedWing($sender);
                        $this->tasks[$sender->getId()] = $task;
                        $this->getScheduler()->scheduleRepeatingTask($task, 10);
                            $sender->sendMessage("§l§aHero§bMC§e>§r§a Đã bật Wing §4Red");
                        }
                            if($args[1] == "off"){
                                $task = $this->tasks[$sender->getId()];
                                unset($this->tasks[$sender->getId()]);
                                $task->getHandler()->cancel();
                                $sender->sendMessage("§l§aHero§bMC§e>§r§c Đã tắt Wing §4Red");
                            }
                    break;
                    case "flame":
                        if(!$sender->hasPermission("flame.wing")){
                            $sender->sendMessage("§l§aHero§bMC§e>§r§c Bạn không có quyền dùng Wing §6Flame");
                        return true;
                    }
                        if($args[1] == "on"){
                        $task = new FlameWing($sender);
                        $this->tasks[$sender->getId()] = $task;
                        $this->getScheduler()->scheduleRepeatingTask($task, 10);
                            $sender->sendMessage("§l§aHero§bMC§e>§r§a Đã bật Wing §6Flame");
                        }
                            if($args[1] == "off"){
                                $task = $this->tasks[$sender->getId()];
                                unset($this->tasks[$sender->getId()]);
                                $task->getHandler()->cancel();
                                $sender->sendMessage("§l§aHero§bMC§e>§r§c Đã tắt Wing §6Flame");
                            }
                    break;
                    default:
                $sender->sendMessage("§9•§4 Wing Red. §e/wing red");
                $sender->sendMessage("§9•§a Wing Green §e/wing green");
                $sender->sendMessage("§9•§6 Wing Flame. §e/wing Flame");
                        break;
                }
            }
        }
        return true;
    }
   
    public function onQuit(PlayerQuitEvent $e) {
        $player = $e->getPlayer();
        $task = $this->tasks[$player->getId()];           
        unset($this->tasks[$player->getId()]);
        $task->getHandler()->cancel();
    }
}


But it doesnt work and it didnt send any error except my particles task because it cant locate the player

 

You did not register events
implement Listener

PHP:

class Main extends PluginBase implements \pocketmine\event\Listener{

register events

PHP:

$this->getServer()->getPluginManager()->registerEvents($this,$this);
