keyboard input

I''ll assume that you made a typo and actually mean WM_KEYDOWN.

opps yeah sorry

hmmm interesting

Well since you know what message you''re responding to, look it up.

hello_there,

The way it works is like this:

Create a global array which has 256 boolean elements.. then use WM_KEYDOWN/WM_KEYUP to set the keys'' states.... eg:

// this is global to the program
BOOL key_buffer[256];

// ... in your Window Proc...

case WM_KEYDOWN:
  {

  key_buffer[wParam] = TRUE;

  } break;

case WM_KEYDOWN:
  {

  key_buffer[wParam] = FALSE;

  } break;

// ... then in your main loop you can do something like this...

while (!done)
  {

  ...

  // if escape key was pressed
  if (key_buffer[VK_ESCAPE])
    // give it a sign it should quit
    SendMessage(hMainWnd, WM_CLOSE, 0, 0);

  ...

  }
 

Hope this helps....

You can get the keystate at any time using GetAsyncKeyState(). For example:

#define KEY_IS_DOWN(x) (GetAsyncKeyState(x) & 0x8000)

if (KEY_IS_DOWN(VK_LEFT))
{
// blah
}
if (KEY_IS_DOWN(VK_RETURN))
{
// etc.
}

This uses the virtual-key codes. See MSDN for info (or the game programming genesis series here, which I think also mentions it).

Of course, if you can track the WM_KEY* messages yourself then this isn''t really necessary.
