Из-за BukkitRunnable не прогружается мир при входе на сервер

[BlackBaroness]

Продолжение этой темы.
Создан класс с листенером, там же ивент onJoin, который исправно работает. В ивенте заложен следующий таск:

        new BukkitRunnable() {
            @Override
            public void run() {
                int clock = -1;
                while (true) {
                    clock++;
                    if (clock == 1) {
                        p.sendMessage(ChatColor.AQUA + "Вы играете " + ChatColor.GOLD + clock + ChatColor.AQUA + " час.");
                    }
                    if (clock == 2 || clock == 3 || clock == 4) {
                        p.sendMessage(ChatColor.AQUA + "Вы играете уже " + ChatColor.GOLD + clock + ChatColor.AQUA + " часа.");
                    }
                    if (clock >= 5 && clock <= 10 ) {
                        p.sendMessage(ChatColor.AQUA + "Вы играете уже " + ChatColor.GOLD + clock + ChatColor.AQUA + " часов.");
                    }
                    if (clock != 0) {
                        p.sendMessage(ChatColor.DARK_GREEN + "Не забывайте отдыхать.");
                    }
                    try {
                        Thread.sleep(3600000);
                    } catch (InterruptedException interruptedException) {
                        interruptedException.printStackTrace();
                    }
                }
            }
        }.runTask(Baroness.plugin);

Почему-то эта конструкция настолько нагружает сервер, что он зависает, а после вообще перестаёт отвечать. Я сделал какую-то ошибку? Может, есть другой способ реализовать это?

Thread.sleep(3600000);

Ну ясно почему зависает сервер. На 1.12 сервер и плагины работают в 1 потоке, поэтому нельзя использовать данный метод. Самый нормальный вариант .runTaskTimer();.
И тебя вообще не смущает, что даже когда игрок выйдет с сервера, таймер перестанет работать?

 

[BlackBaroness]

Можете подсказать, как работает таймер?

И тебя вообще не смущает, что даже когда игрок выйдет с сервера, таймер перестанет работать?

Таймер должен перезапускаться при каждом входе игрока.

 

[BuseSo]

Таймер должен перезапускаться при каждом входе игрока.

Он не будет перезапускаться, всё время будет создавать новый и новый таймер.

Можете подсказать, как работает таймер?

Что именно?
Ты создаёшь таймер, он выполняет весь код в методе run(), потом через интервал времени опять повторяет, и опять, и до тех пор, пока его не остановят (например, методом cancel() или перезагрузкой сервера).

Более-менее, но я бы поступил разумнее:
Можно хранить всех игроков и их время игры в HashMap<Player, Integer>,
А таймер сделать один, как я показывал в другой теме (*тык*), и просто запускать его в onEnable.

Убрав его, я решил проблему, спасибо
Гляну на хэшмап
