C中的连续键盘输入 [英] Continuous keyboard input in C

问题描述

我正在C语言中创建一个控制台应用程序。这是一个游戏，角色掉下来，用户必须按键盘上的特定键。我不知道如何在不暂停掉落字符的情况下检测用户按下了哪个键。当我使用scanf时，程序将等待输入，并且一切都会暂停。
请尽快帮助我！

I am creating a console application in C. This is a game in which characters are falling down and user has to press that specific key on the keyboard. I don't know how to detect which key is pressed by the user without pausing the falling characters. When I use scanf the Program waits for input and everything pauses. Please help me soon!

推荐答案

有一个名为 kbhit（）或<$ c的函数$ c> _kbhit 它在< conio.h> 库中，它返回 true 或 false 取决于是否按下了键。因此，您可以执行以下操作：

There is a function called kbhit() or _kbhit it is in the <conio.h> library it returns true or false depending whether a key was hit. So you can go with something like this:

while (1){
    if ( _kbhit() )
        key_code = _getch();
        // do stuff depending on key_code
    else 
        continue;

也可以使用 getch（）或 _getch 直接从控制台而不是从缓冲区读取字符。您可以阅读有关 conio.h 函数的更多信息在这里它们对于您想做的事情可能非常有用。

Also use getch() or _getch which reads a character directly from the console and not from the buffer. You can read more about conio.h functions here they might be very useful for what you want to do.

注意： conio.h 不是标准库，实现因编译器而异。

Note: conio.h is not a standard library and implementations may vary from compiler to compiler.
