Thread: Getting the char from kbhit()

I need to be able to have a function that I can use like kbhit() that I can get the char out of. No getch(), please. I'm not trying to pause the program. In fact, that's exactly what I want to avoid.

using getch with kbhit wont pause your program if you only call getch if kbhit returns true.

Code:

while( ! kbhit() )
{
     // do stuff
}

ch = getch();

// do other stuff

This won't pause your program because getch will read the key which ended the loop and move on to the other stuff.

Smells good. Let me try it.

Code:

#include <conio.h>
#include <iostream>

using namespace std;

int main( void )
{
   char ch;
	
   // Display message until key is pressed. 
   while( ! kbhit() )
      cout << "Hit me!! ";

   // get the key pressed
   ch = getch();

   cout << endl << "Key struck was " << ch;

   return 0;
}

Try that, took it of msvc help.

Ok. Thanx.

If you want to use kbhit() / getch() actively in a game loop:

Code:

char Key=0;
//Will loop until ESC is pressed
while(Key!=27)
{
  Key=0;
  if(kbhit()) Key=getch();

  //Prints text when ENTER is pressed
  if(Key==13) cout << "You pressed Enter" << endl;
}
