Help

Greetings,
I wrote a Tier System plugin which rewards the player on a tier.
If I try to kill a player with an enchanted sword which has fire aspect enchant and the player got killed not by me but the fire the server crashes. Here is the error:

Code:

Here is the code of my plugin:

PHP:

if($player->getLastDamageCause() instanceof EntityDamageByEntityEvent){
       if($player->getLastDamageCause()->getDamager() instanceof Player){
            if($killdata === $elsotier){
                $killer->sendMessage("§8[§b!§8]§7 Elérted a(z) elsõ Season szintet! Jutalmad:§b 200$");
                $killer->sendTitle("§aSzint 1 feloldva!");
                $killer->sendSubTitle("§7Jutalmad: §6200$");
                $this->getServer()->getPluginManager()->getPlugin("BasicEconomy");
                EconomyAPI::getInstance()->addMoney($killer, 200);
                $pc = $this->getServer()->getPluginManager()->getPlugin("PureChat");
                $pc->setPrefix("1", $killer);
            }
# the code that should be executed when the player reach the second tier
            if($killdata === $masodiktier){
                $killer->sendMessage("§8[§b!§8]§7 Elérted a(z) második Season szintet! Jutalmad:§b 500$");
                $killer->sendTitle("§aSzint 2 feloldva!");
                $killer->sendSubTitle("§7Jutalmad: §6500$");
                $this->getServer()->getPluginManager()->getPlugin("BasicEconomy");
                EconomyAPI::getInstance()->addMoney($killer, 500);
                $pc = $this->getServer()->getPluginManager()->getPlugin("PureChat");
                $pc->setPrefix("2", $killer);
            }

 

These are the variables:

PHP:

public function tierRendszer(PlayerDeathEvent $event){

   $kdr = $this->getServer()->getPluginManager()->getPlugin("KDR");
   $player = $event->getPlayer();
   $killer = $player->getLastDamageCause()->getDamager();
   $killdata = $kdr->getProvider()->getPlayerKillPoints($killer);
   $elsotier = 5;
   $masodiktier = 10;

 

read the error: EntityDamageEvent::getDamager undefined.

 

what is $player->getLastDamageCause()->getDamager(); ??
if you want to get damager (when kill a player) you need to do:

PHP:

//event: EntityDamageByEntityEvent
$player = $event->getEntity(); //return player
$hp = $player->getHealth(); //getting player hp
$maxDamageHit = $event->getFinalDamage(); //getting final dmg

if ($hp - $maxDamageHit >= 0) {
//do stuff
}


now you can use it.

 

Thank you, but if I put $player to the getPlayerKillPoints() the plugin can't get the KDR plugin's data values

PHP:

$killdata = $kdr->getProvider()->getPlayerKillPoints($player);

 

PHP:

public function tierRendszer(PlayerDeathEvent $event){
   if($event->getLastDamageCause() instanceof EntityDamageByEntityEvent){
   $kdr = $this->getServer()->getPluginManager()->getPlugin("KDR");
   $player = $event->getPlayer();
   $killer = $player->getLastDamageCause()->getDamager();
   $killdata = $kdr->getProvider()->getPlayerKillPoints($killer);
   $elsotier = 5;
   $masodiktier = 10;
}


 

yes, isaid check if $event: EntityDamageByEntityEvent
(like this):
