Key imput without getch()

Expand Post »
Hi

I am writing a 2D game that only uses the arrow keys for input. I have done a search on this site fro ways to get input from the arrow keys and have come up with many solutions. However all of them use the getch() function. Normally this would be OK but for this project one of the files that I have to include raises 4 errors and a warning when I include <conio.h> (the header for getch()). The file that doesn't like getch() is DarkGDK, which I downloaded from www.msdn.com for its ease of use when creating games.

I was wondering if there are any alternatives.

I am using Visual C++ 2008 Express running on Windows XP.

Re: Key imput without getch()

Probably the best place for Dark GDK question is Dark GDK community forum...
I can't imagine what's a relation between #include <conio.h> in your modules and errors in Dark GDK files...

Re: Key imput without getch()

All I want to know is how to do what getch() does without using getch().

Re: Key imput without getch()

As far as I know Dark GDK application HAS NO CONSOLE at all. If so you can't use conio.h or Windows API ReadConsole stuff. It's GUI application. Dark GDK has its own keyboard event handling and corresponding API. You can find more info in DarkGDK docs or ask Dark GDK guru on Dark GDK forum.
May be I'm wrong?..

Re: Key imput without getch()

I found what I was looking for on the DarkGDK forum but does anyone know where to view a map of the keyboard with the numbers that correspond to the keys (ex: 71=num pad '8')?

Re: Key imput without getch()

I believe what you're looking for would be the ASCII character codes.

Have you ever heard about Google search?
