Yea well, I'm not going to "re-open" the project to add stuff like that... there were many things I had originally wanted to add, but I just decided not to because I wanted to drop this sloppy project and move onto something else

(if you look at the source you'll see it's un-commented, sloppy, and very n00bish!

)

But hey, I learned a lot from this... so I'm happy

Ways to stop program execution:

Pull out PSU power cable
Press and hold hardware reset
Shut off main power breaker to the house
Climb nearest pole and cut power line to house
Load 12 gauge shotgun and fire at CPU

Nice

hehe

>_< I just tried that thing with climbing the pole and cutting the power line!11`
The execution stopped, BUT NOW I CAN NEVER STOP AN EXECUTION AGAIN >_<

Really? Lucky

i'm trying to make a game that i can use the arrow keys on the keyboard.. but it seems that they have the same ASCII value as some letter keys, and in your code you define them the same.. how does the computer konw the difference when they are pressed?

**Ruski** · 08-13-2002

Use the VK_ extention... eg: VK_LEFT or VK_RIGHT

**GrNxxDaY** · 08-13-2002

huh?

**Ruski** · 08-13-2002

I had that in a tutorial... i cant remember

Code:

case WM_KEYDOWN:
     switch(lParam)
     {
          case 'A':
               letterA();
               break;
          case 'b':     //This won't work, it has to be uppercase.
               letterB();
               break;
          case VK_UP:
               goUp();
               break;
     }
     break;

case WM_KEYUP:
     switch(lParam)
     {
          case 'A':
               unLetterA();
               break;
          case 'b':     //This won't work, it has to be uppercase.
               unLetterB();
               break;
          case VK_UP:
               stopUp();
               break;
     }
     break;

I never tried it, but I think that's how it's supposed to work (although I might have gotten lparam and wparam mixed up).

I used this function to get keypresses:

Code:

bool Keypress(char &Key)
{
	INPUT_RECORD	Event;
	DWORD	NumberOfEvents, EventsRead, EventCounter;

	GetNumberOfConsoleInputEvents(hConsole_in, &NumberOfEvents);

	if (NumberOfEvents == 0)
		return false;
	
	for (EventCounter = 0; EventCounter < NumberOfEvents; EventCounter++)
	{
		PeekConsoleInput(hConsole_in, &Event, 1, &EventsRead);
		if ((Event.EventType == KEY_EVENT) && ((Event.Event.KeyEvent.bKeyDown)))
		{
			ReadConsoleInput(hConsole_in, &Event, 1, &EventsRead);
			Key = Event.Event.KeyEvent.wVirtualKeyCode;
			if (!(FlushConsoleInputBuffer(hConsole_in)))
				exit(0);
			return true;
		}
		else
			ReadConsoleInput(hConsole_in, &Event, 1, &EventsRead);
	}

	return false;
}

So then you could do this:

Code:

char key = 0;
for (;;)
{
	if (Keypress(key))
	{
		switch(key)
		{
		case VK_LEFT:
			// left
		case VK_RIGHT:
			// right
		default:
			// anything else
		}
	}
	// something to do if no key is pressed
}

*sorry, I'm doing a Windows app right now.. thought you meant keypresses in a window.

**GrNxxDaY** · 08-13-2002

wha

**d00b** · 08-13-2002

Hunter thought you meant how to capture keystrokes in a GUI window

I remember some code I saw.. was something like:

Code:

if(GetKeyStat orsomething like that... == VK_UP && 0x80)
{
do whatever();
}

There was a function called GetAsyncKeyState(int vKey)... that way you don't have to go thru all the Windows messages. You just call GetAsyncKeyState, and it'll tell you if vKey is pressed or unpressed.
