Multiple ScoreBoards Problem.

I want to create a ScoreBoard per player so the players can navigate easily through some of their stuff, e.x points.
Here is the code i made:
PlayerListener:

Code:java

package me.vasil7112.<plugin>
 
import org.bukkit.event.player.PlayerJoinEvent;
..//And other imports
 
 
public class PlayerListener implements Listener{
    public static Main plugin;
    public static void init(Main i){
        plugin = i;
    }
 
    @EventHandler(priority=EventPriority.HIGHEST)
    public void onJoin(PlayerJoinEvent e){
        Player player = e.getPlayer();
 
        ScoreBoards.Instance.updateScoreBoard(player); //LINE WITH ERROR
    }
 
    @EventHandler(priority=EventPriority.HIGHEST)
    public void onPlayerChat(AsyncPlayerChatEvent e) {
    }//and other events....
}

ScoreBoardListener..

Code:java

package me.vasil7112.<plugin>;
 
import org.bukkit.Bukkit;
...//And other imports
//ScoreBoard Imports
import org.bukkit.scoreboard.DisplaySlot;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.ScoreboardManager;
 
 
public class ScoreBoards implements Listener{
    public static Main plugin;
    public static ScoreBoards Instance;
    ScoreboardManager manager = Bukkit.getScoreboardManager();;
    Scoreboard board = manager.getNewScoreboard();
    Objective objective;
 
    public static void init(Main i){
        plugin = i;
    }
 
    public ScoreBoards(){
        Instance = this;
    }
 
    //Update scoreboards for all players
    public void updateScoreBoards(){
        for(Player player : Bukkit.getServer().getOnlinePlayers()){
            objective = board.registerNewObjective("SB_" + player.getName(), "dummy");
            objective.setDisplaySlot(DisplaySlot.SIDEBAR);
            objective.setDisplayName("Status");
            objective.getScore(Bukkit.getOfflinePlayer(ChatColor.GREEN + "Points:")).
            setScore(Main.Instance.getConfig().getInt("PlayerStats." + player.getName() + ".points"));
            player.setScoreboard(board);
        }
    }
    //Update ScoreBoard for a specific player
    public void updateScoreBoard(Player player){
        objective = board.registerNewObjective("SB" , "dummy");
        objective.setDisplaySlot(DisplaySlot.SIDEBAR);
        objective.setDisplayName("Status");
        objective.getScore(Bukkit.getOfflinePlayer(ChatColor.GREEN + "Points:")).
        setScore(1); // in this case i don't use the config just for testing.
        player.setScoreboard(board);
    }
}

It was really weird, so i took everything from scoreboard listener and pasted it to the player listener to check(Because i couldn't find something to be null)

Code:java

//Imports e.t.c
public void onJoin(PlayerJoinEvent e){
        Player player = e.getPlayer();
        objective = board.registerNewObjective("SB" , "dummy");
        objective.setDisplaySlot(DisplaySlot.SIDEBAR);
        objective.setDisplayName("Status");
        objective.getScore(Bukkit.getOfflinePlayer(ChatColor.GREEN + "Points:")).
        setScore(1);
        player.setScoreboard(board);
}

And for some reason it worked.
But that isn't what i want. I want to have a listener to fire the commands. (ScoreBoardsListener)
Hopefully someone can help.
Kind regards

 

Scoreboards.Instance is null.

 

Ah yeah!
And all this time i was trying to find the mistake after Scoreboards.Instance
Thanks alot, i fixed it
