The constructor ItemStack(int, int, short) is undefined.

Hey,
I have the following problem : I try to develop a Plugin which give me the head of my opponent
at a kill in the PVP... but I get the following error message and I do not know how to fix it.

---------------------------------------------------------------------------------------------------------------
error message: The constructor ItemStack(int, int, short) is undefined.
---------------------------------------------------------------------------------------------------------------

Code:

package listeners;

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.PlayerDeathEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;


public class Head implements Listener {


@EventHandler (priority=EventPriority.NORMAL)
public void onDeath(PlayerDeathEvent e) {
if(e.getEntity().getKiller() instanceof Player) {
Player killer = e.getEntity().getKiller();

ItemStack Kopf = new ItemStack(397, 1, (short) 3); // <-----here is the problem
ItemMeta meta = Kopf.getItemMeta();
meta.setDisplayName("§6"+e.getEntity().getName());
Kopf.setItemMeta(meta);
killer.getInventory().addItem(Kopf);

}

}
}

 

Can you show me an example for my code? that would be great because i am a beginner

 

Okay ...
no error message but nothing happens
Do not have any experience with plugins ...please do not be mad

Code:

package listeners;

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.PlayerDeathEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;
import org.bukkit.Material;

public class Head implements Listener {
  
  
   @EventHandler (priority=EventPriority.NORMAL)
   public void onDeath(PlayerDeathEvent e) {
     if(e.getEntity().getKiller() instanceof Player) {
       Player killer = e.getEntity().getKiller();
       ItemStack Kopf = new ItemStack(Material.STONE_SWORD, 1);//[B] <-------New
       ItemMeta meta = Kopf.getItemMeta();
       meta.setDisplayName("§6"+e.getEntity().getName());
       Kopf.setItemMeta(meta);
       killer.getInventory().addItem(Kopf);
      
     }
    
   }
}

 

@cyberfreak82 You don't need to check if the killer is a player, just if it's null.

Reason (open) Reason (close)

Player#getKiller() returns a Player, so it can only be a Player object, something that inherits Player (which it won't return), or null.

 

in main registerd but nothing happens ... Main:

Code:

package me.cyberfreak.Belohnung;



import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;



import commands.heal;
import listeners.Head;

public class Main extends JavaPlugin {
   
   
   public void onEnable(){
     PluginManager pm = this.getServer().getPluginManager();
     System.out.println("Plugin erfolgreich aktiviert");
     this.getCommand("heal").setExecutor(new heal());
     
     //registieren des Events
     pm.registerEvents(new Head(), this);
     
     
   }
   
   public void onDisable() {
     
   }

}

 

@cyberfreak82 Did you try printing out messages to debug?

 

I would like to... if I knew how... this is my first Plugin
please do not laugh

 

Learn java first, then read the bukkit docs
