Code:

import java.util.logging.Logger;

import org.bukkit.plugin.java.JavaPlugin;
 
 
 
public class Cookiez extends JavaPlugin {
    private final CookiezEntityListener entityListener = new CookiezEntityListener(this);
    public static Logger log = Logger.getLogger("Minecraft");
        public static int itemid;
        public static int dropsize;
 
 
     
    public void onDisable() {

    }
 
    public void onEnable() {
 
        this.loadconfig();
     
    itemid = this.getConfig().getInt("Config.Zombie-Drop-ID");
    dropsize = this.getConfig().getInt("Config.Zombie-Drop-Size");
 
    this.getServer().getPluginManager().registerEvents(entityListener, this);
 
    getCommand("cookie").setExecutor(new CookieCommandlistener(this));
    PluginDescriptionFile pdfFile = this.getDescription();
    System.out.println( pdfFile.getName() + " version " + pdfFile.getVersion() + " is enabled!" );
    }
     
 
    public void loadconfig() {
            String path1 = "Config.Zombie-Drop-ID";
            String path2 = "Config.Zombie-Drop-Size";
            this.getConfig().addDefault(path1, 357);
            this.getConfig().addDefault(path2, 2);
         
    this.getConfig().options().copyDefaults(true);
    this.saveConfig();
    }
 
 
 
 
     
    }
    

an the CookieEntityListener

Code:

package DarkPantherX.Cookiez;
 
import java.util.List;
import org.bukkit.inventory.ItemStack;
import org.bukkit.entity.Zombie;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.EntityDeathEvent;
 
 
 
public class CookiezEntityListener implements Listener {
 
 
    public static Cookiez plugin;
    private int drpsiz;
    public CookiezEntityListener(Cookiez instance){
        plugin = instance;
        }
 
    @EventHandler
    public void onEntityDeath(EntityDeathEvent event){
        if(event.getEntity() instanceof Zombie){
         
                List<ItemStack> drops = event.getDrops();
             
                if(Cookiez.dropsize <= 9){
                    drpsiz = Cookiez.dropsize;
                 
                }else if(Cookiez.dropsize >= 9 || Cookiez.dropsize <=0 || Cookiez.dropsize == 2){
                 
                    drpsiz = drops.size();
             
                }
             
                for(int i=0; i < drpsiz; i++){
                    ItemStack drop = drops.get(i);
                    drop.setTypeId(Cookiez.itemid);
                 
                            }
                        }
                    }
                }
         
 
     

Can you please tell my, where my problem is? I really can't finde something...

Why not just use getConfig().options().copyDefaults(true); instead of loadconfig(), then create a config.yml in the src folder with all the defaults you want. I suggest using this:

Code:java

 
PluginDescriptionFile pdfFile = this.getDescription();
Logger log = Logger.getLogger("Minecraft");
 
public void onEnable() {
getConfig().options().copyDefaults(true);
saveConfig();
getServer().getPluginManager().registerEvents(entityListener, this);
getCommand("cookie").setExecutor(new CookieCommandListener(this));
log.info(pdfFile.getName() + " version " + pdfFile.getVersion() + " is enabled!");
}

And then this in your listener:

Code:java

 
@EventHandler(public void onEntityDeath(EntityDeathEvent event){
if (event.getEntity() instanceof Zombie){
List<ItemStack> drops = event.getDrops();
int dropsize = Cookiez.getConfig().getInt("Config.Zombie-Drop-Size");
int newdropsize
if (dropsize <= 9){
newdropsize = dropsize;
}else if(dropsize > 9 || dropsize <= 0 || dropsize == 2){
newdropsize = drops.size();
}
 
for (int i = 0; i < newdropsize; i++) {
ItemStack drop = drops.get(i);
drop.setTypeId(getConfig().getInt("Config.Zombie-Drop-ID");
}
}
}

This says that something went wrong involving an ArrayList (most definitely 'drops'). The problem is at Line 37 of your EntityListener, in the EntityDeathEvent.

 

But how should I fix that now? I'm very confused at the moment... Oo

 

really no one?
