Помогите Ошибка 'Could not pass event PlayerDeathEvent'

[Cheater]

Пишу плагин на отправку сообщений игрокам при их смерти.
В общем, вот код:

package ru.Skriep.KM;

import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.PlayerDeathEvent;
import org.bukkit.plugin.java.JavaPlugin;

public class KM extends JavaPlugin implements Listener {
 
    public void onEnable() {
        Bukkit.getServer().getPluginManager().registerEvents(this, this);
    }
 
    public void onDisable() {
      
    }
 
    @EventHandler     
    public void onDeath(PlayerDeathEvent e) {
        Player killed = e.getEntity();
        Player killer = killed.getKiller();
        killer.sendMessage("Вы убили игрока " + killed.getName());
        killed.sendMessage("Вас убил игрок " + killer.getName());
        return;
    }
}

А вот ошибка:

В чём может быть проблема?

 

[TheZefirrkka]

killer null?

 

[Cheater]

killer null?

Не совсем тебя понимаю

 

[Cool_boy]

Не совсем тебя понимаю

Игрок не всегда умирает от другого игрока, и тогда getKiller() даст null, и ошибку

 

[Cheater]

Игрок не всегда умирает от другого игрока, и тогда getKiller() даст null, и ошибку

Я это понимаю, но я (игрок) убиваю другого игрока, и всё равно выдаёт ошибку...

 

[glavrak]

Так не пробовал?
@EventHandler
public void onDeath(PlayerDeathEvent e) {
Player killed = e.getPlayer();
Player killer = killed.getKiller();
killer.sendMessage("Вы убили игрока " + killed.getName());
killed.sendMessage("Вас убил игрок " + killer.getName());
return;
}

 

[Cheater]

Так не пробовал?
@EventHandler
public void onDeath(PlayerDeathEvent e) {
Player killed = e.getPlayer();
Player killer = killed.getKiller();
killer.sendMessage("Вы убили игрока " + killed.getName());
killed.sendMessage("Вас убил игрок " + killer.getName());
return;
}

Я пишу на 1.7.10, тут нету метода getPlayer() для ивента PlayerDeathEvent, а getEntity() сразу возвращает игрока.

 

[Lunyasha]

@EventHandler     
    public void onDeath(PlayerDeathEvent e) {
        Player killed = e.getEntity();
        Player killer = killed.getKiller();
        if (killer != null) {
            killer.sendMessage("Вы убили игрока " + killed.getName());
            killed.sendMessage("Вас убил игрок " + killer.getName());
        }
    }

 

[hyndorik]

Так не пробовал?
@EventHandler
public void onDeath(PlayerDeathEvent e) {
Player killed = e.getPlayer();
Player killer = killed.getKiller();
killer.sendMessage("Вы убили игрока " + killed.getName());
killed.sendMessage("Вас убил игрок " + killer.getName());
return;
}

А зачем return?

Всем спасибо за советы, оказывается, просто плагины конфликтовали между собой. Вот полностью рабочий код, если вдруг кому надо:

package ru.Skriep.KM;

import org.bukkit.entity.Entity;

import org.bukkit.event.entity.PlayerDeathEvent;
import org.bukkit.plugin.java.JavaPlugin;

public class KM extends JavaPlugin implements Listener {
   
    static KM plugin;
   
    public void onEnable() {
        plugin = this;
        Bukkit.getServer().getPluginManager().registerEvents(this, this);
    }
   
    public void onDisable() {
       
    }
   
    @EventHandler      
    public void onDeath(PlayerDeathEvent e) {
        Entity killedEnt = (Entity) e.getEntity();
        if(killedEnt instanceof Player) {
            if(killedEnt != null) {
                Player killed = (Player) killedEnt;
                if(killed.getKiller() != null) {
                    Player killer = killed.getKiller();
                    killer.sendMessage("Вы убили игрока " + killed.getName());
                    killed.sendMessage("Вас убил игрок " + killer.getName());
