kbhit（）或getch（）的问题 [英] Problem with kbhit() or getch()

问题描述

嘿，

我遇到问题 kbhit（）和 getch（）功能。

Hey,
I am having problem with kbhit() and getch() function.

//word = "Hello";
//Funtion is working fine but when I press a key it doesnot enter if(kbhit()) loop.
//Moreover, I tried _getch() next to "if" loop statement but _getch() is also not working :(
void Game::Print_LetterBox(int x,int y,char* word)
{
    int size = strlen(word);
    char key;

    if(_kbhit())
    {
        key = _getch();
    }
    for(int i=0;i<size;i++)
    {
        Letter_Box( word[i],x + i*34,y,"purple");
        for(int j=0;j&lt;size;j++)
        {
            if(word[j] == key)
                Letter_Box( word[i],x+i*34,y,"red");
        }
    }
    Animated_Character( x + size*34, 540 , 5);
}

任何帮助!!

Any help!!

推荐答案

I认为你的问题是如果不是循环 - 这是一次条件测试。如果测试通过，则执行下面的语句（或复合语句）中的代码。如果不是，则完全跳过该条件，并立即继续执行下一个语句。我怀疑你想在时使用，而不是，如果，它会循环。

I think your problem is that if is not a loop - it''s a one time conditional test. If the test passes, then the code in the statement (or compound statement) below it is executed. If it isn''t then the condition is skipped completely, and execution continues immediately with the next statement. I suspect that you want to use while rather than if which does loop.
