Solved Remove OfflinePlayers from a scoreboard team.

I've been stuck with this same problem for quite a bit now, and I haven't gotten it to work. My problem is with scoreboard teams. I'm trying to get it set up that I have a series of scores, and each score has a different prefix and suffix. In order to do this, I have to make a team for each score. I CAN achieve this, but I am creating a new instance of a scoreboard every time I do this. This causes an extremely annoying flashing. I can kind of fix this by changing the prefix and suffix, but I am unable to change the actual score its self.

I could either 1- remove the team from the scoreboard, or 2- remove the offline players from the team and add them back after. I have tried making a list of the offline players, and then removing them from the team using

Code:

team.removePlayer(OfflinePlayer)

but it does not remove, even if the team is still displaying the same offline player. I am unsure how to do this, if anyone knows and can tell me, I would appreciate it very much. Thank you!

I do not have the code in which I tried using the list, etc. because I rolled it back to its previous state with the annoying flashing.

 

Can you show a bit more of your code, including how "team" is defined?

 

Code:

Team team = board.registerNewTeam("stats");

I just looked through the javadocs, and I think I found something that may work, which is:

Code:

team.unregister();

I'm testing it right now.

Turns out, it's flashing differently now. I have changed the code enough that I can show it to you, to demonstrate the weird flashing. Here's my code of 2 classes:

Code:

package com.memecraft.scoreboard;
 
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.ScoreboardManager;
 
import com.memecraft.main.MemeCraftSG;
 
public class VotingScoreboard extends CustomScoreboard {
 
    private ScoreboardManager manager = Bukkit.getScoreboardManager();
 
    public void createScoreboard(Player player) {
 
        Scoreboard board = manager.getNewScoreboard();
        Objective objective = board.registerNewObjective("votes", "dummy");
 
        updateObjective(objective, board, player);
 
        player.setScoreboard(board);
        playerScoreboards.remove(player.getName());
        playerScoreboards.put(player.getName(), board);
    }
 
    public void updateScores(Player player) {
 
        Scoreboard board = playerScoreboards.get(player.getName());
 
        clearAllScores(board);
 
        Objective objective = board.getObjective("votes");
        updateObjective(objective, board, player);
 
        player.setScoreboard(board);
        playerScoreboards.remove(player.getName());
        playerScoreboards.put(player.getName(), board);
    }
 
    private void updateObjective(Objective objective, Scoreboard board, Player player) {
 
        int scores = 5;
        int highest = MemeCraftSG.getPluginInst().getHelper().getAvailibleMaps().size() + scores;
 
        modifiedScore(board, " ", "", "", objective, highest, 0);
        modifiedScore(board, "Time Remaining", generateSpaces(5) + "§b", "§7:" + generateSpaces(5), objective, highest, 1);
        modifiedScore(board, "§l" + getCountdownTime(), generateSpaces(5), generateSpaces(5), objective, highest, 2);
        modifiedScore(board, "  ", "", "", objective, highest, 3);
        modifiedScore(board, "§bMaps§7: ", generateSpaces(5), generateSpaces(5), objective, highest, 4);
 
        for (int i = 0; i < MemeCraftSG.getPluginInst().getHelper().getAvailibleMaps().size(); i++) {
            String maps = MemeCraftSG.getPluginInst().getHelper().getAvailibleMaps().get(i);
            String color = "§7";
 
            if (MemeCraftSG.getPluginInst().getHelper().getVotedMap(player.getName()).equalsIgnoreCase(maps))
                color = "§e";
 
            modifiedScore(board, "§b" + maps, generateSpaces(5) + color + "» ", "§7: " + MemeCraftSG.getPluginInst().getHelper().getTimesVoted(maps) + generateSpaces(5), objective, highest, scores + i);
 
        }
 
        objective.setDisplaySlot(DisplaySlot.SIDEBAR);
        objective.setDisplayName("§b§lVotes");
    }
}

Code:

package com.memecraft.scoreboard;
 
import java.util.HashMap;
 
import org.bukkit.Bukkit;
import org.bukkit.OfflinePlayer;
import org.bukkit.entity.Player;
import org.bukkit.scoreboard.DisplaySlot;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Score;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.Team;
 
import com.memecraft.main.MemeCraftSG;
 
@SuppressWarnings("deprecation")
public class CustomScoreboard {
 
    public HashMap<String, Scoreboard> playerScoreboards = new HashMap<String, Scoreboard>();
 
    public String generateSpaces(int spaces) {
        String spacesString = "";
        for (int i = 0; i < spaces; i++) {
            spacesString = spacesString + " ";
        }
 
        return spacesString;
    }
 
    public void clearAllScores(Scoreboard board) {
        for (OfflinePlayer player : board.getPlayers()) {
            board.resetScores(player);
        }
    }
 
    public void modifiedScore(Scoreboard board, String string, String prefix, String suffix, Objective objective, int highest, int listDown) {
        Team team = null;
 
        if (board.getTeam("team" + listDown) != null)
            board.getTeam("team" + listDown).unregister();
 
        team = board.registerNewTeam("team" + listDown);
 
        team.setPrefix(prefix);
        team.setSuffix(suffix);
 
        OfflinePlayer op = Bukkit.getOfflinePlayer(string);
 
        team.addPlayer(op);
 
        Score score = objective.getScore(op);
        score.setScore(highest - listDown);
    }
 
    public String getCountdownTime() {
 
        int s = MemeCraftSG.getPluginInst().getCountdown().getCountdown() - 1;
 
        return String.format("%d:%02d:%02d", s / 3600, (s % 3600) / 60, (s % 60));
 
    }
 
    public void removeScoreboard(Player player) {
        player.getScoreboard().clearSlot(DisplaySlot.SIDEBAR);
    }
 
}

I update the scoreboard every second, and it flashes every second.

Fixed it. Marking as solved.
