Plugin Help Help with scoreboard

I created a new scoreboard inside onEnable with

ScoreboardManager Manager = Bukkit.getScoreboardManager();
Scoreboard board = Manager.getNewScoreboard();

I want to know how to access this scoreboard from a different class.

 

@ShownPC
Create what's called a getter. Initialize the variable board outside of the onEnable() method, then set board to a new Scoreboard. Then create a new method (can be called anything) called getBoard() and have that method return the board instance. Now all you have to do in your other class is

Code:

plugin.getBoard().doSomething();

(plugin is the instance of your Main class)

 

how do I create the instance of the main class?

 

@ShownPC Don't create an instance of it. The server already creates one for you. It depends on what kind of class file you want the instance in. If this is an event class, just add a constructor for the class that takes your main class as an argument.

Code:

private Plugin p;
public EventClass(Plugin plugin) {
        this.p = plugin;
}

Then, when you register the event in your main class,

Code:

Bukkit.getPluginManager().registerEvents(new EventClass(this), this);

You just pass this (the instance of your main class) to the event constructor.

Now* in your class you have a variable p, that is your is main class.

*changed Not to Now

 

this is doesnt working , in the console it says there is a problem in our main class in line 63
and what we have in that line is:
Scoreboard board = Manager.getNewScoreboard();

 

@aceMlg
Make sure you are just initializing the Scoreboard board object outside of the onEnable() method.

Code:

Scoreboard board;
ScoreboardManager manager;
public void onEnable() {
        //other stuff
        manager = Bukkit.getScoreboardManager();
        board = manager.getNewScoreboard();
}

If there are any errors this time, please post the error log using [URL]https://pastebin.com[/URL].

 

already did that..
this is the method:
ScoreboardManager Manager = Bukkit.getScoreboardManager();
Scoreboard board = Manager.getNewScoreboard();
public Scoreboard getBoard(){

return board;}

 

@aceMlg If what you showed me right there is exactly what you have in your code, you did not already do that. I have part of that code in the onEnable() method and you don't have anything in there. I define the variables just above the onEnable() method and don't set them to any value until the onEnable() method is called on server start.

Main class​

Code:

package me.x1machinemaker1x.arierajail.objects;

import org.bukkit.Bukkit;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.ScoreboardManager;

public class Main extends JavaPlugin {
   
    private ScoreboardManager manager;
    private Scoreboard board;
    public void onEnable() {
       
        //set commands/events
       
        Bukkit.getPluginManager().registerEvents(new TestEvent(this), this);
       
        manager = Bukkit.getScoreboardManager();
        board = manager.getNewScoreboard();
    }
   
    public Scoreboard getBoard() {
        return board;
    }

}

Event class​

Code:

package me.x1machinemaker1x.arierajail.objects;

import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerMoveEvent;
import org.bukkit.scoreboard.Scoreboard;

public class TestEvent implements Listener {
   
    private Main main;
   
    public TestEvent(Main main) {
        this.main = main;
    }
   
    @EventHandler
    public void onPlayerMove(PlayerMoveEvent e) {
        Scoreboard board = main.getBoard();
    }

}
