如何刷新玩家来更换皮肤？

Question

我正在尝试更改服务器上玩家的皮肤。我查了一下，发现您需要发送正确的数据包，其中一个是删除，另一个是添加播放器，但在我的版本（使用 Spigot buildtools 安装的 1.21.1 nms --> 使用 Mojang 映射).

我尝试使用其他数据包（例如 ClientboundRespawnPacket），但这也不起作用。这是我当前的代码：

@Override
    public boolean onCommand(@NotNull CommandSender sender, @NotNull Command command, @NotNull String s, @NotNull String[] strings) {
        String PlayerName = sender.getName();
        if (!(sender.hasPermission("northmclobbyutils.duckify")) && sender instanceof Player) {
            sender.sendMessage("§cYou do not have permission to use this command!");
            return true;
        }
        if (!(sender instanceof Player)) {
            PlayerName = "Console";
        }
        for (Player p : sender.getServer().getOnlinePlayers()) {
            System.out.println(p.getName());
            CraftPlayer cp = (CraftPlayer) p;
            ServerPlayer sp = cp.getHandle();
            sp.setCustomName(Component.literal("§6Duck"));
            PropertyMap pm = sp.getGameProfile().getProperties();
            pm.removeAll("textures");
            System.out.println("Duckifying " + p.getName());
            pm.put("textures", new Property("textures", "ewogICJ0aW1lc3RhbXAiIDogMTczMTIxMzc0NTk1NywKICAicHJvZmlsZUlkIiA6ICI1OWJlOTUyY2EyNjc0OWE4OTM1YmQ5MGQxNmMyN2M4OCIsCiAgInByb2ZpbGVOYW1lIiA6ICJUaGVQZW5zcGlubmV1ciIsCiAgInNpZ25hdHVyZVJlcXVpcmVkIiA6IHRydWUsCiAgInRleHR1cmVzIiA6IHsKICAgICJTS0lOIiA6IHsKICAgICAgInVybCIgOiAiaHR0cDovL3RleHR1cmVzLm1pbmVjcmFmdC5uZXQvdGV4dHVyZS80MTlkNTQ3NTk3YTQ2NmM0MWY1YmI3YjE0Y2MyMTZmMTk2ZDNhZjI0YjJhYWQ3MWZjMjlkNWE4ZTlkY2RiZmY5IgogICAgfQogIH0KfQ==", "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"));
            updatePlayerSkin(p);
            sp.connection.send(new ClientboundPlayerInfoRemovePacket(new ArrayList<>(List.of(sp.getUUID()))));
            sp.connection.send(new ClientboundPlayerInfoUpdatePacket(Action.ADD_PLAYER, sp));
        }
        sender.sendMessage("§aAll players have been duckified!");
        return true;
    }

现在发生的情况是，玩家从列表中消失，但他们的皮肤保持不变。

Answer 1

您可以隐藏并再次显示播放器。为此，您需要像这样使用 Player#showPlayer 和 Player#hidePlayer：

for (Player p : Bukkit.getOnlinePlayers()) {
    setDuckPlayerSkin(p);
    for (Player all : Bukkit.getOnlinePlayers()) {
        all.hidePlayer(plugin, p); // hide player
        all.showPlayer(plugin, p); // show it again
    }
}

这将以更安全的方式完成发送数据包的最后 2 行。
