Re: How to captue enter, up, down, left, right and Fx

[Nick Hill <nikhilwiz@yahoo.com>]

If u're usin' Windoze zen u gotta use tha GetMessage func. to receive
the user'z key stroke. In plain ol' DOS, getch() does tha job
perfectly. it returnz tha ASCII code. The arrow keyz in DOS return 2
charectors: the first charector is a space (i think) the next charector
is one of GHIKLMNPQ, which are respectively for the numeric keypad from
top left to bottom right. Since u say u're using OpenGL... u can't use
DOS unless u're planning to use GCC or DJGPP with Mesa which has OpenGL
support for DOS.

so ultimately u're code should be (in DOS):

char c;
while(!kbhit());

c=getch();
if (c==13) // do code fer <Enter> key. This is a normal            //
key, it returns only one charector.

if(kbhit())
{
 c=getch();
 switch(c)
 {
  
  case 'H': // do code for up arrow key
  case 'K': // left
  case 'M': // right
  case 'P': // down
    .       // similiarly fer tha oth' keyz.
    .
    .
 }
}
