Need help for passing object to other class (scoreboard)

Hello,

Since yesterday I started to make my first plugin and there appeared some issues. I have class for scoreboard. And there is methods to make scoreboard, load it and change scores.

Here it is:

Code:java

package eu.anavicius.TomTom1997.TomTowerDefence;
 
import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.Listener;
import org.bukkit.scoreboard.DisplaySlot;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Score;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.ScoreboardManager;
 
public class Votes implements Listener {
 
    public Scoreboard board;
    public Score scores[] = new Score[6];
 
    public void sBoard () {
        ScoreboardManager manager = Bukkit.getScoreboardManager();
        Scoreboard board = manager.getNewScoreboard();
 
        Objective obj = board.registerNewObjective("VoteMap", "dummy");
        obj.setDisplayName("Vote for maps!");
        obj.setDisplaySlot(DisplaySlot.SIDEBAR);
 
        Score scores[] = new Score[6];
 
        for (int i = 1; i<6; i++) {
            scores[i] = obj.getScore("Map " + i);
            scores[i].setScore(0);
            this.scores[i] = scores[i];
        }
    }
 
    public void setScore(int i) {
        int sc = scores[i].getScore();
        scores[i].setScore(sc+=1);
 
        for (Player p : Bukkit.getOnlinePlayers()) {
            p.setScoreboard(board);
        }
    }
 
    public void showTo (Player player) {
        player.setScoreboard(this.board);
    }
 
}
[/i][/i][/i][/i][/i][/i]

The problem is that I don't know how to change scores or load it to the player in different classes. Example:

Code:java

//On my main class
 
public class Main extends Javaplugin {
    Votes vote = new Votes();
 
    public void onEnable () {
        vote.sBoard();//Initialized scoreboard
    }
}
//another class
 
public class JoinDicsEvents {
    //what should i write here to acces my initialized
    //scoreboard (I mean write vote.showTo(player){})
    //Everytime when I try something there appears NPE
}

 

Just make your Scoreboard public and other classes can access it (as you have already done). For example:

Code:java

public class JoinDicsEvents {
    // This will be the same scoreboard as initialized
    Scoreboard scoreboard = Votes.scoreboard;
    // Now you can do what ever you want with it:
    scoreboard.registerNewObjective(...);
 
    // And the same with your score array:
    Score scores[] = Votes.scores;
    scores[2].setScore(31415);
}

And BTW It has to be "JavaPlugin" instead of "Javaplugin" in the main class

 

I see there 'Votes.scores' and 'Votes.scoreboad'. Maybie there is other solution without using static?
