import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.EntityDamageEvent;
import org.bukkit.event.entity.PlayerDeathEvent;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin implements Listener{
 
@EventHandler
public void onPlayerDeath(PlayerDeathEvent event){
if (event.getEntity().getLastDamageCause() == null) {
return;
}
 
 
Player killer = event.getEntity().getKiller();
 
 
EntityDamageEvent.DamageCause cause = event.getEntity().getLastDamageCause().getCause();

Have you registered the class as an event listener in your onEnable method?

 

Lol, you don't have an onEnable at all, no events get registered.

 

Lol my no on Sid is showing it works fine! Thanks for the help guys!!!!!

 

A'ight cool.

 

XD I didn't even realize that's his main class.
