C++等待和休眠问题

Question

好的，我正在处理一个菜单，它的工作原理是每 3 秒出现一个新选项，但我正在努力做到这一点，以便在这 3 秒内我可以按下一个按钮来激活一些东西现在看这里:

dvar(-1, 0, "e \"Prestige and rank settings\"");
Sleep(35);
dvar(-1, 0, "c \"Set prestige one\"");
if (Key_Down(0, 0x02)) {
  dvar(-1, 0, "c \"Setting 1st prestige, will be kicked\"");
  Sleep(1000);
  dvar(-1, 0, "c \"^43\"");
  Sleep(1000);
  dvar(-1, 0, "c \"2\"");
  Sleep(1000);
  dvar(-1, 0, "c \"^41\"");
  Sleep(1000);
}
Sleep(3000);

上面的问题是在“Set prestige one”之后跳到下一个 Sleep(3000) 和下一个选项，现在我需要找到一种方法来继续使用 if statement witch is a button within that 3 秒，而不是它休眠线程并使按钮不可用，除非您在文本加载之前按下它。

我几乎需要做的是让线程休眠，而不是让它等待那 3 秒，这样我仍然可以使用该 if 语句。

我认为您会尝试用以下思想进行编程::

1. 事件驱动。
2. 多线程。使用系统计时器事件服务。
3. 基于状态机。

伪代码是这样的::

int State = IDLE;
dvar(-1, 0, "e \"Prestige and rank settings\"");
Sleep(35);
dvar(-1, 0, "c \"Set prestige one\"");

while (1)
{
    switch (SomeEvent)
    {
    case ON_Key_down:
        if (Key == 0x02)
        {
            if (State == IDLE || State == KEY_PRESSED_SET1stPRESTIGE_Finish)
            {
                State = KEY_PRESSED_SET1stPRESTIGE_1stSTEP;
                dvar(-1, 0, "c \"Setting 1st prestige, will be kicked\"");

                Timer_Event_AfterMS(1000);   // make request event after 1sec to system alarm service
            }
            else
            {
                // ignore do something
            }
        }
        break;
    case ON_Timer_SomeSec:
        if (State == KEY_PRESSED_SET1stPRESTIGE_1stSTEP)
        {
            dvar(-1, 0, "c \"^43\"");
            State = KEY_PRESSED_SET1stPRESTIGE_2ndSTEP;
            Timer_Event_AfterMS(1000);   // make request event after 1sec to system alarm service
        }
        else if (State == KEY_PRESSED_SET1stPRESTIGE_2ndSTEP)
        {
            dvar(-1, 0, "c \"2\"");
            State = KEY_PRESSED_SET1stPRESTIGE_3rdSTEP;
            Timer_Event_AfterMS(1000);   // make request event after 1sec to system alarm service       
        }
        else if (State == KEY_PRESSED_SET1stPRESTIGE_3rdSTEP)
        {
            dvar(-1, 0, "c \"^41\"");
            State = KEY_PRESSED_SET1stPRESTIGE_4rdSTEP;
            Timer_Event_AfterMS(1000);   // make request event after 1sec to system alarm service       
        }
        else if (State == KEY_PRESSED_SET1stPRESTIGE_4rdSTEP)
        {
            State = KEY_PRESSED_SET1stPRESTIGE_Need3SEC;
            Timer_Event_AfterMS(3000);   // make request event after 3sec to system alarm service       
        }
        else if (State == KEY_PRESSED_SET1stPRESTIGE_Need3SEC)
        {
            State == KEY_PRESSED_SET1stPRESTIGE_Finish;
        }
        break;
    default:
        break;
    }
}
