Code:

package com.gmail.jwnordquist.LogoutTP;
 
import org.bukkit.Location;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerLoginEvent;

public class PlayerListener extends JavaPlugin implements Listener {
    public LogoutTP plugin;
   
    public PlayerListener(LogoutTP instance){
        plugin = instance;
    }
   
    @EventHandler 
    public void onPlayerLogin(PlayerLoginEvent event) {
        Player p = event.getPlayer();
       
        Location location = p.getLocation();
        location.setX(getConfig().getDouble("x"));
        location.setY(getConfig().getDouble("y"));
        location.setZ(getConfig().getDouble("Z"));
        location.setYaw((float) getConfig().getDouble("yaw"));
        location.setPitch((float) getConfig().getDouble("pitch"));
       
        p.teleport(location);
        p.sendMessage("Welcome");
       
    }
}

 

The file does not exist.
Add a config.yml to your project folder and make a default config.
In your onEnable, write this line:

Code:

saveDefaultConfig();

 

Well, the thing is, the config has already been made and can be edited using the command from the main class, but when i try and use the listener, it throws the error.

 

I thought it was your main class... You can only have ONE main class. The main class is the ONE that extends JavaPlugin which can only happen ONCE.

Then just do plugin.getConfig()

 

Make your listener extend your main class, not JavaPlugin

 

Thanks for the help! Just one last question, is it possible to get variables from my main class and vice versa?

 

I believe you could do this:

if(plugin.variableName ...)

 

Keep all global variables in your main class and let your other classes extend your main class.
