Solved Need help with my Scoreboard

Hey. I think I'm stopping my Scoreboard/Task wrong.

Here is the Code:

Main.php:

PHP:

<?php

namespace Deeonix\DCore;

use pocketmine\plugin\PluginBase;
use pocketmine\event\player\PlayerJoinEvent;
use pocketmine\event\player\PlayerQuitEvent;
use pocketmine\event\Listener;
use pocketmine\utils\TextFormat;

class Main extends PluginBase implements Listener{
    
    public $tasks = [];

    public function onEnable() {
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
        $this->getLogger()->info(TextFormat::GREEN."Enabled!");
    }
    
    public function onDisable() {
        $this->getLogger()->info(TextFormat::RED."Disabled!");
    }
    
    public function onLoad() {
        $this->getLogger()->info(TextFormat::YELLOW."Loaded!");
    }

    public function onJoin(PlayerJoinEvent $event) {
        $player = $event->getPlayer();
        $name = $player->getName();
        $event->setJoinMessage(TextFormat::GREEN.TextFormat::BOLD."» ".TextFormat::RESET.TextFormat::GREEN.$name);
        $this->enableSB($player);
        //Server::getInstance()->broadcastMessage(TextFormat::GREEN.TextFormat::BOLD."» ".TextFormat::RESET.TextFormat::GREEN.$name);
    }
    
    public function onQuit(PlayerQuitEvent $event) {
        $player = $event->getPlayer();
        $name = $player->getName();
        $event->setQuitMessage(TextFormat::RED.TextFormat::BOLD."« ".TextFormat::RESET.TextFormat::RED.$name);
        //Server::getInstance()->broadcastMessage(TextFormat::RED.TextFormat::BOLD."« ".TextFormat::RESET.TextFormat::GREEN.$name);
    }
    
    public function enableSB($player) {
        $task = new SB($this, $player);
        $taskid = $task->getTaskId();
        $this->getServer()->getScheduler()->scheduleRepeatingTask($task, 20);
        $this->tasks[$taskid] = $taskid;
    }

    public function disableSB($id) {
        unset($this->tasks[$id]);
        $this->getServer()->getScheduler()->cancelTask($id);
    }
    
}

SB.php:

PHP:

<?php

namespace Deeonix\DCore;

use pocketmine\scheduler\PluginTask;
use pocketmine\Player;
use Deeonix\DCore\Main;

class SB extends PluginTask {
    
    public $plugin;
    private $player;
    private $name;

    public function __construct(Main $plugin, Player $player) {
        parent::__construct($plugin);
        $this->plugin = $plugin;
        $this->player = $player;
        $this->name = $this->player->getName();
    }

    public function getPlugin() {
        return $this->plugin;
    }
    
    public function onRun($tick) {
        while($this->plugin->getServer()->getPlayer($this->name)->isOnline()) {
            $this->plugin->getServer()->getPlayer($this->name)->sendTip("                                                             Name: ".$this->name."\n                                                             Rang: Master");
        }
        $this->plugin->disableSB($this->getTaskId());
    }
    
}

When a player leava the server i get this message:

 

This causes an infinite loop.

 

Fixed:

PHP:

<?php

namespace Deeonix\DCore;

use pocketmine\scheduler\PluginTask;
use pocketmine\utils\TextFormat;
use pocketmine\Player;
use Deeonix\DCore\Main;

class SB extends PluginTask {
    
    public $plugin;
    private $player;
    private $name;

    public function __construct(Main $plugin, Player $player) {
        parent::__construct($plugin);
        $this->plugin = $plugin;
        $this->player = $player;
        $this->name = $this->player->getName();
    }

    public function getPlugin() {
        return $this->plugin;
    }
    
    public function onRun($tick) {
        if($this->plugin->getServer()->getPlayer($this->name) === null) {
            $this->plugin->disableSB($this->getTaskId());
        } else {
            $this->plugin->getServer()->getPlayer($this->name)->sendTip("                                                             Name: ".$this->name."\n                                                             Rang: Master");
        }
    }
    
}

Thanks for the hint

 

The hint of @AshBull was enough to solve the problem ;D
