mkae it so when the user presses...

I want to make it so when the user presses the esc or anouther key the p[rogram will do somthing? How do I do that?

Part of it depends on specifically what key you want pressed, but mostly it's what type of application you're doing. Is this a Windows app? If so, what API? You'll want to look into event handlers, me thinks.

WinAPI is pretty simple.

Create an array of boolean values of key presses.

Code:

---

........

bool bKey[255];

........

// in your message switch do this

LRESULT CALLBACK WinProc ( HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam )
{

    switch ( uMsg ) {

        case WM_KEYDOWN:

            bKey [wParam] = true;

        break;

       
        case WM_KEYUP:

            bKey [wParam] = false;

        break;

    }

}

........

if ( bKey [VK_ESC] ) PostQuitMessage ( 0 );

but if your not using WinAPI then um.. what are you using.

With conio..

its probably like

Code:

---


if ( kbhit () == KEYS_CODE )

// or

var = getch ();
if ( var == KEYS_CODE )

---

Where KEYS_CODE is the ASCII value.

oh well just a counsl program. Possibly the esc key, if not ctrl+q, or something that "means" quit.

Alright then - use conio like Vicious showed you. It's not standrd, but it's common.

Yeah I know Rune is a big fan of it :P

Oh, and im ont sure if thats how it would work.. but probable.

Rune, I think you should look into SDL. Its not that hard really.

firstly I droped getch(). So I'm not a big fan on conio.h anymore.

And what is SDL?

Simple DirectMedia Layer. It's written more for C programmers but it will work in C++ also. It gives you graphics, sound, support for peripherals, threading, event handling, etc... Lots of good stuff. Go to www.libsdl.org to learn more.

kbhit() is used only to tell if a keystroke is waiting in the input buffer (according to my compiler's MSDN). It's used in combination with getch():

Code:

---

bool done = false;
while(!done)
{
  //do your game code or whatever
  if(kbhit())
  {
      char theKey = getch();
      if(theKey == 'X')
        done = true;
  }
}

You can play around with it to suit your needs (although, as has been mentioned, it's very non-standard).

Quote:

---

if(kbhit())
{
char theKey = getch();
if(theKey == 'X')
done = true;
}

Alright that bit of code I get a little more. It works fine too.

Thanks

Yeah thats what I meant :P
