Thread: redrawing a symbol on keypress.

I've got a function here that manipulates some variables depending on what key is pressed: my problem is that this is called from a loop and the loop continues to run with this method if the user enters a key or not. I need a method that pauses the execution of the program until the user hits a valid key.

Code:

void controlPlayer()
{
	if ( GetAsyncKeyState ( VK_UP ) & SHRT_MAX )
		--coY;
	else if ( GetAsyncKeyState ( VK_DOWN ) & SHRT_MAX )
		++coY;
	else if ( GetAsyncKeyState ( VK_LEFT ) & SHRT_MAX )
		--coX;
	else if ( GetAsyncKeyState ( VK_RIGHT ) & SHRT_MAX )
		++coX;

}

I think most of us know what those headers do, so the comments are not needed there
