Need some help

Greetings,

I'm new at coding and I need some help, because I don't know why this isn't working.
Thanks any help in advance, have a great day!

PHP:

public function tierSystem(PlayerDeathEvent $event){

$kdr = $this->getServer()->getPluginManager()->getPlugin("KDR");
$player = $event->getPlayer();
$killdata = $kdr->getProvider()->getPlayerKillPoints($player);
$firsttier = 5; # Award should be given after the 5th kill
$killer = $player->getLastDamageCause()->getDamager();

if($player->getLastDamageCause() instanceof EntityDamageByEntityEvent){
    if($player->getLastDamageCause()->getDamager() instanceof Player){
        if($killdata === $firsttier){
            $killer->sendMessage("§8[§b!§8]§7 You are on the first Tier! Your reward:§b 500$");
            $killer->sendTitle("§aTier 1 unlocked!");
            $killer->sendSubTitle("§7Your reward: §6500$");
            $this->getServer()->getPluginManager()->getPlugin("EconomyAPI");
            EconomyAPI::getInstance()->addMoney($killer, 500);
        }
    }
}

 

You gave no useful information.

Are there any errors? Did you register Listener? What's the expected behavior and whats the one you observe?

 

I would like to make a plugin which rewards the player for every 5th kill. I get the kills data from the KDR plugin.
In the current code, if the player has 5 kill, he or she should get 500 dollar after the 5th kill. When I get the 5th kill, nothing happens.

 

I'll teach you a valuable lesson. Simple output of the data can help you find the cause

PHP:

public function tierSystem(PlayerDeathEvent $event){

# Add log message to see if this code gets executed at all
$this->getServer()->getLogger()->notice(__CLASS__."::".__METHOD__." executed (Line: ".__LINE__.")");

$kdr = $this->getServer()->getPluginManager()->getPlugin("KDR");
$player = $event->getPlayer();
$killdata = $kdr->getProvider()->getPlayerKillPoints($player);
$firsttier = 5; # Award should be given after the 5th kill
$killer = $player->getLastDamageCause()->getDamager();

if($player->getLastDamageCause() instanceof EntityDamageByEntityEvent){
    # DEBUG
    $this->getServer()->getLogger()->notice("Last damage cause was caused by entity");
    if($player->getLastDamageCause()->getDamager() instanceof Player){
    # DEBUG
    $this->getServer()->getLogger()->notice("Last damager was instanceof Player");
    $this->getServer()->getLogger()->notice("Checking: {$killdata} === {$firsttier}");
        if($killdata === $firsttier){
            $killer->sendMessage("§8[§b!§8]§7 You are on the first Tier! Your reward:§b 500$");
            $killer->sendTitle("§aTier 1 unlocked!");
            $killer->sendSubTitle("§7Your reward: §6500$");
            $this->getServer()->getPluginManager()->getPlugin("EconomyAPI");
            EconomyAPI::getInstance()->addMoney($killer, 500);
        }
    }
}

Do you have registered listener? Something like this:

PHP:

public function onEnable() {
    $this->getServer()->getPluginManager()->registerEvents($this, $this);
}


 

Yes I did, I registered the Listener

 

Thanks for teaching me, successfully I found the error, and now everything works. Thanks for your time and help. Have a wonderful day!
