Question

您好我每隔X秒尝试执行一次任务，我遇到问题：

Thread joinThread = new Thread(() -> {
    for (int i = 0; i < amount; i++) {
        Player player = new Player(user, RandomUtils.randomString(10), host, p, event.getSession());
        player.join();
    }

    try {
        Thread.sleep(delay);
    } catch (InterruptedException ignored) {
        ignored.printStackTrace();
    }
});

joinThread.start();

看起来Thread.sleep(delay)被忽略了，因为我的线程每隔ms执行一次而不是延迟

这是我的join方法：

public void join(){
    GameProfile profile = session.getFlag("profile");
    Client c = new Client(host, port, new MinecraftProtocol(name), new TcpSessionFactory(proxy));
    c.getSession().addListener(new SessionAdapter() {
        @Override
        public void packetReceived(PacketReceivedEvent event) {
            if (event.getPacket() instanceof ServerJoinGamePacket) {
                user.setBotAmount(u.getBotAmount()+1);
                user.addBot(event.getSession());
                System.out.println("Player bot joined");
            }
        }

        @Override
        public void disconnected(final DisconnectedEvent event) {
            if(event.getCause() != null) event.getCause().printStackTrace();
            user.setBotAmount(u.getBotAmount() -1);
        }
    });
    c.getSession().connect();
}

如果删除player.join();，它就像魅力一样有什么建议？我不知道自己做错了什么。

首先，线程的主体（run方法的主体）执行一次。

你正试图为每个玩家做出延迟。然后，您需要将Thread.sleep(delay)放在player.join()：

之后的循环中

for (int i = 0; i < amount; i++) {
    Player player = ...;
    player.join();

    try {
        Thread.sleep(delay);
    } catch (InterruptedException reallyIgnored) {}
}

否则，在所有玩家都已经处理完毕后你将会延迟这是没有意义的。

确保delay变量设置正确。 Thread.sleep需要时间（以毫秒为单位）。为了感受差异，该值应为>1000。

Java Thread.sleep（延迟）不起作用
