как вынести scoreboard в отдельный класс?

[artem2015]

если пишу так:

package test;
import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerMoveEvent;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scoreboard.DisplaySlot;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.Team;
 
 
public class main extends JavaPlugin implements Listener{
 
    Scoreboard sb;
    Objective obj;
    Team team;
 
    public ScoreB score;
 
    public  void onEnable() {
        Bukkit.getPluginManager().registerEvents(this, this); // register plugin on server
        //score.init();
        sb= Bukkit.getScoreboardManager().getNewScoreboard();
        obj=sb.registerNewObjective("SCORE", "admin");
        obj.setDisplaySlot(DisplaySlot.SIDEBAR);
        obj.setDisplayName("allscores");
        team=sb.registerNewTeam("myteam");
        team.setCanSeeFriendlyInvisibles(true);
        team.setAllowFriendlyFire(false);
    }
 
 
 
    @EventHandler
    public void onPlayerMove(PlayerMoveEvent event) throws Exception
    {
        //score.Setscore();
        for (Player p : Bukkit.getOnlinePlayers()){
            org.bukkit.scoreboard.Score s = obj.getScore(p);
            s.setScore(555);
            p.setScoreboard(sb);
            }
   
        return;
    }
 
}

то работает

если пытаюсь вынести scoreboard в отдельный класс:

package test;
import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.scoreboard.DisplaySlot;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.Team;
 
 
public class ScoreB {
    Scoreboard sb;
    Objective obj;
    Team team;
 
    public void init() {
    sb= Bukkit.getScoreboardManager().getNewScoreboard();
    obj=sb.registerNewObjective("SCORE", "admin");
    obj.setDisplaySlot(DisplaySlot.SIDEBAR);
    obj.setDisplayName("allscores");
    team=sb.registerNewTeam("myteam");
    team.setCanSeeFriendlyInvisibles(true);
    team.setAllowFriendlyFire(false);
    }
 
    public void Setscore() {
 
    for (Player p : Bukkit.getOnlinePlayers()){
    org.bukkit.scoreboard.Score s = obj.getScore(p);
    s.setScore(555);
    p.setScoreboard(sb);
    }
    }
}

и вызывать его из главного:

package test;
import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerMoveEvent;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.Team;
 
 
public class main extends JavaPlugin implements Listener{
 
    Scoreboard sb;
    Objective obj;
    Team team;
 
    public ScoreB score;
 
    public  void onEnable() {
        Bukkit.getPluginManager().registerEvents(this, this); // register plugin on server
        score.init();
    }
 
 
 
    @EventHandler
    public void onPlayerMove(PlayerMoveEvent event) throws Exception
    {
        score.Setscore();
        return;
    }
 
}

то при инициализации плугина в строке score.init();
выдаёт ошибку:

и далее в другой строке score.Setscore(); другую ошибку:
