Lobby and setLobby

Hi, i'm trying to create an simple minigame and i need to set lobby. I've created this:

Code:java

package Minigame;
 
import org.bukkit.Location;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin {
    public Location lobby;
    public static Main plugin;
    public void onEnable(){
 
    }
    public void onDisable(){
 
    }
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
        if(cmd.getName().equalsIgnoreCase("mg-setlobby")){
            Player p = (Player) sender;
            p.getLocation().getBlockX();
            p.getLocation().getBlockY();
            p.getLocation().getBlockZ();
            p.getLocation().getBlock().getWorld();
            p.sendMessage("You have been setted lobby");
        }
        if(cmd.getName().equalsIgnoreCase("mg-lobby")){
            Player p = (Player) sender;
            p.teleport(lobby);
        }
        return false;       
    }
}

When I type /mg-setlobby i think that I set lobby normally. But, whn I type /mg-lobby I found this in console:

Code:

[09:25:43 INFO]: XFarwar issued server command: /mg-lobby
[09:25:43 ERROR]: null

Helps?

 

You're not even setting the lobby location. You're just getting them... Besides you're not even saving the values. Its temp.

 

I'd recommend that you learn java before you jump into Bukkit developing.

 

Code:java

public Location lobby

u dont need that.

Code:java

p.getLocation().getBlockX();
p.getLocation().getBlockY();
p.getLocation().getBlockZ();
p.getLocation().getBlock().getWorld();
p.sendMessage("You have been setted lobby");

Omg Come Back When You Learn Bukkit API
