Get killer

Hello Coder,
I was searching a methode to get the killer of a player. I saw something in the src code on Pocketmine but dont understand that.
If i take the EntityDamageByEntityEvent
i only can get the damager where the normal player is alive. But i want to get the damager and normal player where the normal player got killed by the damger (sorry for bad description)

Yes Thank you but i think you forgot to get the name

PHP:

public function onDeath(EntityDeathEvent $event){
        $entity = $event->getEntity();
        $cause = $entity->getLastDamageCause(); //get the last damage cause
        if($cause instanceof EntityDamageByEntityEvent){ //if the cause is by an another entity
            $killer = $cause->getDamager(); //gets the event damager
            if($killer instanceof Player){
                $entity->sendMessage($killer->getName()." is your killer"); //;)
            }
        }
    }

$killer should define the player name.

Nope. The Output would be Player(1) or player(2...)
Sensej is rigth you have to use getName() if you want the Player Name

Gotcha! Thanks for helping out

Isn't $killer in this situation the Player object? Wouldn't it spit out an error?

Entity::__toString()
