Know player name who kill an other player by Projectile

In an PayerInteractEvent player are able to launch snowball with 10 dommage if snowball hit an other player

But how can i get thé $killer and the $victim?

PHP:

public function onDamage(EntityDamageEvent $event){
        $victim = $event->getEntity();
        $cause = $event->getCause();
      
        if($cause == EntityDamageEvent::CAUSE_PROJECTILE){
            if($event instanceof Player){
                $event->setDamage(10);
                $killer = $event->getDamager();
                $welt = $killer->getLevel()->getFolderName();
                $arenaname = $this->getConfig()->get("arena");
                      
                $this->Title($victim, "§4Death", $killer->getName());
                $this->Title($killer, "§2Kill", $victim->getName());
                      
                $this->GunItems($victim);
                $this->GunItems($killer);
                      
                $deathmsg = $this->getLanguage()->get("player.death");
                $deathmsg = str_replace("{player}", $killer->getName(), $deathmsg);
                      
                $victim->sendMessage($this->prefix . $deathmsg);
                      
                $killmsg = $this->getLanguage()->get("player.kill");
                $killmsg = str_replace("{player}", $victim->getName(), $killmsg);
                $killer->sendMessage($this->prefix . $killmsg);
                return;
            }
        }
    }

 

You do realize $event in this case can never be a Player instance, right?

Back to your question, you can always var_dump($event) and get the required cases.

In your case, $event->getDamager() should be the projectile and $event->getDamager()->getOwningEntity() should be the entity who fired the projectile (this can also return null at times, so make sure you handle that too. For example when a player fires a projectile and logs out, and the projectile later hits an entity).

 

When i add your code

PHP:

$event->setDamage(10);

Doesnt working

 

try this code it should work fine.

PHP:

public function onDamage(EntityDamageEvent $event){
        $victim = $event->getEntity();
        $cause = $event->getCause();
   
        if($cause == EntityDamageEvent::CAUSE_PROJECTILE){
            if($victim instanceof Player){
                $event->setDamage(10);
                $killer = $event->getDamager();
                $welt = $killer->getLevel()->getFolderName();
                $arenaname = $this->getConfig()->get("arena");
                   
                $this->Title($victim, "§4Death", $killer->getName());
                $this->Title($killer, "§2Kill", $victim->getName());
                   
                $this->GunItems($victim);
                $this->GunItems($killer);
                   
                $deathmsg = $this->getLanguage()->get("player.death");
                $deathmsg = str_replace("{player}", $killer->getName(), $deathmsg);
                   
                $victim->sendMessage($this->prefix . $deathmsg);
                   
                $killmsg = $this->getLanguage()->get("player.kill");
                $killmsg = str_replace("{player}", $victim->getName(), $killmsg);
                $killer->sendMessage($this->prefix . $killmsg);
                return;
            }
        }
    }


 

PHP:

public function onDamage(EntityDamageByEntityEvent $event){
        $victim = $event->getEntity();
        $cause = $event->getCause();
       
        if($cause == EntityDamageEvent::CAUSE_PROJECTILE){
            if($victim instanceof Player){
                $event->setDamage(10);
                $killer = $event->getDamager();
                if($killer instanceof Player){
                    $deathmsg = $this->getLanguage()->get("player.death");
                    $deathmsg = str_replace("{player}", $killer->getName(), $deathmsg);
                   
                    $victim->sendMessage($this->prefix . $deathmsg);
                   
                    $killmsg = $this->getLanguage()->get("player.kill");
                    $killmsg = str_replace("{player}", $victim->getName(), $killmsg);
                   
                    $killer->sendMessage($this->prefix . $killmsg);
                    return;
                }
            }
        }
    }

 

That won't work, $event->getDamager() is a projectile

PHP:

$projectile = $event->getDamager();
if($projectile instanceof Projectile){//pocketmine/entity/projectile/Projectile
    $projectileShooter = $projectile->getOwningEntity();//this can be null if the victim was damaged after the shooter logged out.
}


 

Maybe i do use last dommage?
