FAQ: Directional Keys - Useing in Console

[BMJ]

*sigh*

Example of virtual key usage:

#include <windows.h>
#include <iostream>

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

	GetNumberOfConsoleInputEvents(GetStdHandle(STD_INPUT_HANDLE), &NumberOfEvents);

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

	return false;
}

int main()
{
	char key = 0;
	for (;;)
	{		
		if (Keypress(key))
		{
			if (key == VK_LEFT)
				std::cout << "Left\n";
			if (key == VK_RIGHT)
				std::cout << "Right\n";
			if (key == VK_DOWN)
				std::cout << "Down\n";
			if (key == VK_UP)
				std::cout << "Up\n";
			if (key == VK_ESCAPE)
				return 0;
		}
	}
	return 0;
}
