Windows控制台应用程序上的平台游戏和改进输入

我目前正在使用Windows控制台制作平台游戏。但是,当我发出多个命令时,我遇到了一个问题。

例如,当我让我的角色在一个方向上运行然后按下跳跃时,忘记了运行键并且必须再次按下这一事实。

是否有输入法可以检查正在按住或按下哪些键?或者更确切地说,是一种检查重复输入的方法吗?

供参考,这是我目前的代码: http://pastebin.com/2y6Rf6rb

我目前使用的输入法是:

/*** Keyboard Input ***/
/* Number of Events */
DWORD numEvents = 0;

/* Events from Console Read */
DWORD numEventsRead = 0;

/* Find Number of Console Events */
GetNumberOfConsoleInputEvents(rHnd, &numEvents);

/*If there is an Event */
if(numEvents != 0)
{
    /* Create Buffer to Store Events */
    INPUT_RECORD *eventBuffer = new INPUT_RECORD[numEvents];

    /* Read Console Events to that Buffer and Save that many Events */
    ReadConsoleInput(rHnd, eventBuffer, numEvents, &numEventsRead);

    /* Cycle through Events that have Happened */
    for(DWORD i = 0; i < numEventsRead; i++)
    {
        /* If Event was a Key Press */
        if(eventBuffer[i].EventType == KEY_EVENT && eventBuffer[i].Event.KeyEvent.bKeyDown == TRUE)
        {
            /* Right ('d' Key) 0x44*/
            if(eventBuffer[i].Event.KeyEvent.wVirtualKeyCode == 0x44)
            {
                key = 'd';

                for(y = 0; y < 3; y ++)
                {
                    if(gdisplay[PY - y][PX + 4] == square1[0] && gdisplay[PY - y][PX + 4 + 1] == square1[1])
                    {
                        movecheck = 0;
                    }
                }

                if(momentum < 0)
                {
                    momentum++;
                }

                else if(movecheck == 1)
                {
                    PX+=2;
                    momentum++;

                    if(panime == 1)
                    {
                        panime = 2;
                    }

                    else if(panime == 2)
                    {
                        panime = 1;
                    }
                }
            }

            /* Left ('a' Key) 0x41*/
            else if(eventBuffer[i].Event.KeyEvent.wVirtualKeyCode == 0x41)
            {

                if((PX - 2) >= 2)
                {

您可以尝试的一件事是,在发出keyDown时,您可以将某些标记设置为true,例如rightKeyPressed = true,然后您还可以检查keyUp,在这种情况下,您可以执行rightKeyPressed = false并为每个正在运行的键执行此操作。我相信你遇到的问题是当你按下你所持有的键以外的键时,你不再接收该键的keyDown事件。因此,您需要一些方法来保存特定键被按下,直到它实际释放。这样,当您使用跳转命令中断时,即使系统没有收到该密钥的rightKeyPressed事件,keyDown(或任何方向)仍然为真。

这需要进行一些重要的重构,因为您目前只跟踪key变量。举个例子,这里有一些假代码可以证明这一点:

public void keyPressed(Key key){
    if(key==RIGHT)
      runningRight = true;
      runningLeft = false;
    else if(key==LEFT)
      runningLeft = true;
      runningRight = false;
    else if(e.getKeyCode()==CTRL)
      jump = true;
}

public void keyReleased(KeyEvent e){
    if(key==RIGHT)
      runningRight = false;
    else if(key==LEFT)
      runningLeft = false;
}
