因此，我正在制作一款游戏，通过按A，B或C对玩家进行任务，使三个框中的一个消失。如果一个框消失以显示一个较小的框，则该用户获胜。我很难做到这一点，以便当用户获胜时，总猜测量的计数器和错误的猜测不再增加，因为此时，人们可以按下按钮继续递增这两个变量（分别恰当地命名为totalGuesses和wrongGuesses）。有谁知道我怎么能完成这项任务？我敢肯定它相对简单，但它让我起了作用。非常感谢你。

答案 0 :(得分：0)
为什么不这样做才能开始：
void keyboard(unsigned char key, int x, int y)
{
if (win)
{
if ((key == 'a') || (key == 'b') || (key == 'c'))
{
// ignore a,b,c if there is already a winner
return;
}
}
switch (key)
{
