当我执行命令时，我的记分牌没有停止

Question

向正在阅读本文的人问好，我正在开发一个插件，它可以让你在死亡时添加一个记分牌，但对于我来说，我无法弄清楚如何从玩家身上删除记分牌，我正在尝试 player.setScoreboard(null);但这似乎不起作用，无论如何有人可以告诉我如何删除记分牌这就是我所拥有的

    List<String> pop = new ArrayList<String>();
    
    
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (label.equalsIgnoreCase("scorecount")) {
            if (!(sender instanceof Player)) {
                sender.sendMessage("You cannot do that console!");
                return true;
            }
            if (sender.hasPermission("scorecount.use")) {
                if (args.length == 3) {
                    this.sendInvalid(sender);
                    Player pvp = Bukkit.getPlayer((String)args[1]);
                    if (pvp == null) {
                        sender.sendMessage((Object)ChatColor.RED + "Player " + args[1] + " is not online.");
                        return true;
                    }
                    if (args[0].equalsIgnoreCase("add")) {
                        if (pop.contains(pvp.getName())) {
                            sender.sendMessage((Object)ChatColor.RED + pvp.getName() + " Already has a ScoreList!");

                        }
                        pop.add(pvp.getName());
                        sender.sendMessage((Object)ChatColor.GREEN + pvp.getName() + " Now has the ScoreList!");

                        Score score = obj.getScore("____________");
                        score.setScore(3);

                        score2.setScore(2);

我以前没有使用过 Bukkit，我找不到 API 文档，但是 this 教程建议您需要执行以下操作来“删除”玩家的记分板：

pvp.setScoreboard(Bukkit.getScoreboardManager().getNewScoreboard());

当我执行命令时，我的记分牌没有停止
