Disable the exp adding

Does anyone know how to disable the exp adding when a player kills the others ?
(When Player A kills Player B, Player A will get exp)

Cant you disable it in the pocketmine.yml?

Set Player Level anytime Nothing

PHP:

class Task extends PluginTask{
    public $owner;
    public function __construct($owner){
        parent::__construct($owner);
        $this->owner = $owner;
    }
    public function onRun($currentTick){
        foreach ($this->owner->getServer()->getOnlinePlayers() as $p){
                $p->setExpLevel(null);
        }
    }
}

this task ^ if you notknow to task you can do this Event but task better

PHP:

public function onMove(PlayerMoveEvent $event){
      $player = $event->getPlayer();
      $name = $player->getName();
    
      $player->setExpLevel(null);
    }

This code ^ on Player Move set exp player nothing but task anytime

That looks like a horrific method to do that. You are running a task EVERY time a player moves, or in the first example, constantly. Not to mention that the OP asked for the player to not get XP when they kill a player, not to disable XP entirely.

I would suggest getting the XP an Entity(Or Player) is supposed to drop when they die, and setting that to 0.

Thanks for the clarification =)

PHP:

public function onKill(PlayerDeathEvent $event){
    $cause = $event->getEntity()->getLastDamageCause();
        if($cause instanceof EntityDamageByEntityEvent){
            $killer = $cause->getDamager();
               
                $killer->setExpLevel(null);
      }
  }

No just no, disable it in the YAML.

maybe OP mean to disable drop of EXP to make server more swift?

If you use Genisys: https://github.com/iTXTech/Genisys/.../event/player/PlayerExperienceChangeEvent.php

If any of you noticed the full question, it stated that they didn't want Experience transaction when a player kills another player, but they never stated that they wanted to disable Experience entirely.

There is a simple way to do it, just cancel experience spawn.

PHP:

public function onSpawn(\pocketmine\event\entity\EntitySpawnEvent $e){
    if($e->getType() == 69){
        $e->setCancelled(true);
    }
}
