registerCommands(); Error

Hey,

When I start my Server this Error comes:

Code:

So,

These are the 2 classes:

Main.java (open) Main.java (close)

Code:

package de.dunklestoast.gadgets;

import org.bukkit.ChatColor;
import org.bukkit.event.Listener;
import org.bukkit.plugin.java.JavaPlugin;

import de.dunklestoast.gadgets.CommandWilli;
import de.dunklestoast.gadgets.CommandTeleport;

public class Main extends JavaPlugin implements Listener{
   
   
    public static String prefix = ChatColor.translateAlternateColorCodes('&', "&7[&agGadgets&7] &f");
    public static String prefcmd = ("[Gadgets]");

   
    @Override
    public void onEnable() {
        registerCommands();
       
        this.getServer().getPluginManager().registerEvents(this, this);
        System.out.println(Main.prefcmd + " Started...");
       
    }
   

    public void onDisable() {
        System.out.println(Main.prefcmd + " Stopped...");
    }
   

   
   
   
   
    public void registerCommands() {
    getCommand("teleport").setExecutor(new CommandTeleport(this));
   
   
    CommandWilli Willi = new CommandWilli(this);
    getCommand("willi").setExecutor(Willi);
    }
}

and

CommandWilli.java (open) CommandWilli.java (close)

Code:

package de.dunklestoast.gadgets;

import org.bukkit.ChatColor;
import org.bukkit.Location;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.CreatureType;
import org.bukkit.entity.Creeper;
import org.bukkit.entity.Player;

@SuppressWarnings("deprecation")
public class CommandWilli implements CommandExecutor {

    @SuppressWarnings("unused")
    private Main plugin;

    public CommandWilli(Main main) {
        this.plugin = main;
    }

    @SuppressWarnings({})
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
            Player p = (Player) sender;
            Location loc = p.getLocation();
            Creeper creeper = (Creeper) p.getWorld().spawnCreature(loc, CreatureType.CREEPER);
            creeper.setCustomName(ChatColor.GOLD + "Willi");
            creeper.setCustomNameVisible(true);
            creeper.setPowered(true);
            //creeper.shootArrow();
       
   
        return true;

   
   
   
    }
   
    }
   

Where is the Mistake?

 

Error : "at de.dunklestoast.gadgets.Main.registerCommands(Main.java:36) ~[?:?]"
Try with this :

Code:java

 
@Override
public void onEnable() {
getCommand("teleport").setExecutor(new CommandTeleport(this));
getCommand("willi").setExecutor(new CommandWilli(this));
}
 

 

@MaTaMoR_ what you have there is just the commands taken out of the secondary method into onEnable method, this wont do any changes as far as the error is concerned. Instead OP probably hasn't registered the commands in plugin.yml properly so the NPE is thrown.
EDIT: please avoid spoon feeding people. It doesn't help the just to copy paste code without having the intrest of reading it and understanding it. Thanks.

 

"Spoon feeding" hahaha, shot ....
CommandWilli Willi = new CommandWilli(this);

 

@dunklesToast Your original code should work provided you register the commands in plugin.yml

 

@MaTaMoR_

??? how does that affect the code? it is practically the same as creating the obj in the method parameters.
