Ich hoffe ihr könnt mir helfen

at Commands.spawn.onCommand(spawn.java4) ~[?:?]

der fehler entsteht in der Klasse spawn zeile 34, wie brauchen also diese klasse um zusehen wo der Fehler ist nicht die klasse setup

 

[MrPyro13]

Hier die Spawm Class:

package Commands;

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

public class spawn implements CommandExecutor {
   
    //Imports
   
    private de.mrpyro13.hub.main main;
    public spawn(de.mrpyro13.hub.main plugin){
        this.main = plugin;
    }

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        //SCRIPT ANFANG
       
        if (sender instanceof Player) {
           
            Player p = (Player) sender;
           
            String world = main.system_cfg.getString("system.spawn.world");
            double x = main.system_cfg.getDouble("system.spawn.x");
            double y = main.system_cfg.getDouble("system.spawn.y");
            double z = main.system_cfg.getDouble("system.spawn.z");
            double yaw = main.system_cfg.getDouble("system.spawn.yaw");
            double pitch = main.system_cfg.getDouble("system.spawn.pitch");
           
            Location loc = new Location(Bukkit.getWorld(world), x, y, z);
           
            loc.setYaw((float) yaw);
            loc.setPitch((float) pitch);
           
            p.teleport(loc);
            p.sendMessage(main.prefix + " " + main.tp);
           
        } else {
           
            sender.sendMessage(main.error_prefix + " " + main.error_no_console);
           
        }
       
        //SCRIPT ENDE
        return true;
    }

}

Nur warum bugt es, wenn ich /setup eingebe in der spawn Class

Nur warum bugt es, wenn ich /setup eingebe in der spawn Class

Dazu müsste ich die main klasse sehen ^^
kannst du mal makieren wo zeile 34 ist?

 

[MrPyro13]

In der spawn Class:

Location loc = new Location(Bukkit.getWorld(world), x, y, z);

FEHLER:
In der Main:
this.getCommand("spawn").setExecutor(new Commands.spawn(this));
this.getCommand("setup").setExecutor(new Commands.spawn(this));
-> this.getCommand("setup").setExecutor(new Commands.setup(this));
-> er möchte aus der system.yml teleportiert
-> system.yml ist aber nciht beschrieben
-> welt = null
