Trying to check the customname of an entity

I'm just tryting to check the customname of a mob, I tried ".getEntity().getCustomName().equalsIgnoreCase("Heligiex Guard")".
This is the "full" code:

Code:java

public void onEntityDeath(EntityDeathEvent event){
        if(event.getEntity().getCustomName().equalsIgnoreCase("Heligiex Guard")){
            Bukkit.broadcastMessage(ChatColor.GREEN + "Heligiex Guard has been defeated!" );
            Bukkit.broadcastMessage(ChatColor.GOLD + "Diamond ore is no longer blocked!" );
            ItemStack im = Helgstone();
            Random numb = new Random();
            im.setAmount(numb.nextInt(10) + 45);
        }
    }

 

Crack498 Are you getting NPEs?

 

The issue is?
Any errors?
Do a if entity.hascustomname before looking for,it

 

Make sure the event is registered.

 

First of all, you don't have the @EventHandler annotation above your method. Second, make sure your listener is registered. Third, check if the entity has a name by calling entity.hasCustomName(), before trying to use a compare method (like equals())

 

The code is put directly on the main code:

Code:java

package me.Crack498;
 
import java.util.ArrayList;
import java.util.List;
import java.util.Random;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Material;

import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Code extends JavaPlugin {
 
    @Override
    public void onEnable() {
        new BlockListener(this);
    }
 
    public void onDisable() {
 
    }
 
    public static ItemStack Helgstone(){
        ItemStack Helgstone = new ItemStack(Material.CLAY_BRICK);
        ItemMeta meta = Helgstone.getItemMeta();
        List<String> lore = new ArrayList<String>();
        lore.add("A stone from the Healgiex realm");
        meta.setDisplayName("Helgstone");
        meta.setLore(lore);
        return Helgstone;
    }
 
    public void onEntityDeath(EntityDeathEvent event){ // <-- HERE IS THE CODE
        if(event.getEntity().getCustomName().equalsIgnoreCase("Heligiex Guard")){
            Bukkit.broadcastMessage(ChatColor.GREEN + "Heligiex Guard has been defeated!" );
            Bukkit.broadcastMessage(ChatColor.GOLD + "Diamond ore is no longer blocked!" );
            ItemStack im = Helgstone();
            Random numb = new Random();
            im.setAmount(numb.nextInt(10) + 45);
        }
    }

Is this code in the appropiate place to be? First time trying to code bukkit so I don't untderstand a lot of its functions
