DelayedTask won't work.

This is my task code

PHP:

<?php

namespace HotshotHD;

use pocketmine\scheduler\PluginTask;
use pocketmine\plugin\Plugin;
use pocketmine\Player;
use pocketmine\entity\Effect;

class Task extends PluginTask {
  
        public function __construct(Plugin $owner, Player $player) {
      
        parent::__construct($owner);
        $this->player = $player;
    }
  
    public function onRun($currentTick) {
            $effectid = 1;
        $effectamp = 0;
        $effectvis = false;
        $effectdu = 50000000000000000;
        $effect = Effect::getEffect($effectid);
      
        $effect->setVisible(false);
        $effect->setDuration($effectdu);
        $effect->setAmplifier($effectamp);
    }
  
    public function cancel() {
      
        $this->getHandler()->cancel();
    }
    }



?>

And I'm trying to call on it in the PlayerDeathEvent like this

PHP:

        $this->getServer()->getScheduler()->scheduleDelayedTask(new Task($this, $player), 100);
   

but it doesn't work. No error messages or anything. Can anyone help?

Never I mind. I figured out the problem. I forgot to add

PHP:

$this->player->addEffect($effect);

My bad on that.

No I got it to work. It gives the effect 5 seconds after death.
