Solved How to use getConfig() not from the main class? (event listeners classes)

[MkdirGit]

I'm stuck with getConfig() on listeners class.
how to fix this?

package example.example_for_u.JoinEvent;

import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.plugin.Plugin;


public class JoinEvent implements Listener {

   Plugin MyPlugin = Bukkit.getPluginManager().getPlugin("example_for_u");


    @EventHandler(priority = EventPriority.HIGHEST)
    public void onPlayerJoin(PlayerJoinEvent event) {


         Player JoinedPlayer = event.getPlayer();

        MyPlugin.getConfig().getBoolean("exampleBoolean")
    }
}

// how to get config from another class not from the main class?

You create a constructor in JoinEvent that takes an instance of your main plugin and then assign it to a field in JoinEvent. Then when you register the event in your main class' onEnable method, you can pass this to the constructor for JoinEvent.

I found this more usefull

public class PluginName extends JavaPlugin {

public static PluginName instance;

@Override
public void onEnable() {
// Plugin shutdown logic
    instance = this;
}

@Override
public void onDisable() {
// Plugin shutdown logic

}

Hello guys, For a long time already I have struggled with getting instances of plugin I've tried some ways (Even using a method to get it) but it...

Thanks for the help anyway!

While that does work, it really violates a core concept about object-oriented programming. Using static to store state like that can lead to issues if someone uses the unsupported reload command. It's highly recommended to stick to using objects as the language intended and pass state around through constructors (or more complicatedly, with dependency injection).

I would recommend Google Guice dependency injection, while it may seem hard at first, you'll get used to it. https://www.spigotmc.org/threads/tutorial-spigot-plugins-dependency-injection.295218/
I recommend to follow the best practices.
