Scoreboard System

[Manered]

example usage:

public final class ExamplePlugin extends JavaPlugin implements Listener {

    private final Map<Player, CustomScoreboard> scoreboards = new HashMap<>();

    @Override
    public void onEnable() {
        Bukkit.getPluginManager().registerEvents(this, this);

        /* Refreshes all scoreboards every 1 second */
        Bukkit.getScheduler().runTaskTimerAsynchronously(this, () -> {
            for (CustomScoreboard scoreboard : this.scoreboards.values()) {
                refreshScoreboard(scoreboard);
            }
        }, 0, 20L);
    }

    @EventHandler
    public void onJoin(PlayerJoinEvent event) {
        Player player = event.getPlayer();

        CustomScoreboard scoreboard = new CustomScoreboard(player);

        scoreboard.setTitle(ColorUtils.color("<#ff0000>Scoreboard API"));

        this.scoreboards.put(player, scoreboard);
    }

    @EventHandler
    public void onLeave(PlayerQuitEvent event) {
        Player player = event.getPlayer();

        CustomScoreboard scoreboard = this.scoreboards.remove(player);

        if (scoreboard != null) {
            scoreboard.delete();
        }
    }

    public void refreshScoreboard(CustomScoreboard scoreboard) {
        Player player = scoreboard.getPlayer();
        Spark spark = SparkProvider.get();

        // Get the TPS statistic (will be null on platforms that don't have ticks!)
        DoubleStatistic<StatisticWindow.TicksPerSecond> tps = spark.tps();

        double lastTps = tps.poll(StatisticWindow.TicksPerSecond.SECONDS_5);

        scoreboard.setLines(
                ScoreboardUtils.emptyLine(),
                "Ping: " + player.getPing() + "ms",
                "TPS: " + lastTps,
                ScoreboardUtils.emptyLine()
        );
    }
}

or:

CustomScoreboard scoreboard = new CustomScoreboard(player)
  .setTitle("Hello!")
  .setLines("test", "")

FYI this is just supposed to be a modified FastBoard. it's basically just to make it more like a builder.
