Minecraft Minecraft Plugin Fehlermeldung!

[maltz]

Hallo,
Ich bin aktuell dabei ein Minecraft Plugin zu schreiben bei dem man mit einem Befehl zu einer Zufalligen Koordinate Teleportiert wird! (in der Plugin.yml ist alles drin!)
Aber immer wenn ich meinen Befehl eingebe kommt eine seltsame Fehlermeldung:

[18:01:07 ERROR]: null

Hier ist noch die Klasse die den Command enthält:

package de.maltz.skyblock.cmds;

import java.util.Random;

import org.bukkit.Location;
import org.bukkit.World;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

public class sbcreate implements CommandExecutor {

    @Override
    public boolean onCommand(CommandSender sender, Command command, String cmd, String[] args) {
        if(sender instanceof Player){
            Player p = (Player)sender;
            World w = p.getWorld();
            double x = w.getSpawnLocation().getX() + new Random().nextInt(1000 - 2000) + 2000;
            double z = w.getSpawnLocation().getZ() + new Random().nextInt(1000 - 2000) + 2000;
            double y = w.getSpawnLocation().getY() + new Random().nextInt(150 - 50) + 50;
            Location loc = new Location(w, x, y, z);
            p.teleport(loc);
          
        }
      
        return false;
    }
}

Danke schon mal im vorraus!

In deiner seltsamen Fehlermeldung steht genau beschrieben was für ein Fehler auftaucht und vorallem auch wo.

Caused by: java.lang.IllegalArgumentException: bound must be positive
        at java.util.Random.nextInt(Random.java:388) ~[?:1.8.0_25]
        at de.maltz.skyblock.cmds.sbcreate.onCommand(sbcreate.java:19) ~[?:?]

Daher frage ich mich, wie man dir jetzt genau helfen soll.

@maltz der fehler liegt in, wie du in der Fehlermeldung lesen kannst, in Zeile 19. Da hast du versucht eine Zufallszahl zwischen -1000 (1000 - 2000 = -1000) zu bestimmen. wenn du eine Zahl zwischen 1000 und 2000 haben möchtest, kannst du einfach eine zwischen 0 und 1000 nehmen und 1000 addieren. ^^
