用于在Windows控制台中运行的游戏的C ++控件

我正在尝试制作一个在命令提示符下运行的小型2人游戏。 在我开始制作球员控制之前，一切都很好。 因此，为了捕获键盘键，我认为最好的解决方案是使用getch（）函数。 这是因为getch（）即时获取键，而不是在屏幕上显示，等待输入或其他键被按下。

据我所知，实现这一目标的代码非常简单：

c=getch(); switch(c) { case 'a': make player 1 go left break; case 'd': make player 1 go right break; case 's': make player 1 go down break; case 'w': make player 1 go up break; case 'h': make player 2 go left break; case 'k': make player 2 go right break; case 'j': make player 2 go down break; case 'u': make player 2 go up break; } 

当然，一切都在一个while循环中。

问题是我需要两个玩家能够在同时按下控件的同时移动。 使用getch（）当玩家1在玩家2按下分配给左移动的键之后向右移动时，玩家1阻止玩家2，因为他们都按下移动键。 当然，如果玩家2释放该键并按下指定的另一个键，则他在阻止玩家1的同时控制移动，等等。

为了让自己更容易理解，使用如下代码：

 c=getch(); switch(c) { case 'a': cout <<"a"; break; case 'd': cout <<"b"; break; } 

当有人按下“a”键时，输出将是“aaaaaaaaaaaaaa”，并且在别人按下“b”后，即使第一个人保持“a”，输出也将变为“aaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbb”。 如果第一个人释放’a’并再次按下它，输出将是“aaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbaaaaaaaaaaaaaa”，因为另一个人持有’b’。 为了让我的游戏工作，当他们都按下’a’和’b’时，我相信输出应该像“ababababababababab”。

老实说，我已经尝试了迄今为止我能想到的一切，但我是C / C ++编程的新手，所以也许我对这些编程语言没有足够的经验来使它工作。 我没有必要让我的getch（）+ switch（）策略工作，任何其他建议也会受到欢迎。 但他们必须恢复到Windows控制台。

在此先感谢您的时间

你的想法是正确的。 在一天结束时，它可能看起来像这样：

 void Keypressed() { if (kbhit()) { keypress =getch(); switch (keypress ) { case key_F1: displayHelp(); break; case key_LEFT: case key_RIGHT: break; case key_UP: PlayersPad.y-=3;if (PlayersPad.y<0) PlayersPad.y=0; break; case key_DOWN: PlayersPad.y+=3;if (PlayersPad.y>18) PlayersPad.y=18; break; case key_ENTER: break; case key_SPACE: break; case key_TAB: autoPlay=-autoPlay; if (autoPlay>0) { setcolor(79);gotoxy(62,23);printf("cheat on " );setcolor(15); } else { setcolor(79);gotoxy(62,23);printf("cheat off " );setcolor(15); } break; } } } 

作为一个额外的奖励，这里是我写的Pong游戏的代码，它是玩家与玩家或玩家对比计算机。
