Hi:
I’m programming a BangBang clone, so I need to ask the user the angle and speed. However, I can’t make
the numeric keyboard work. Here’s a fragment of code about what I’m trying to achieve:

case SDL_KEYDOWN:
char ch;
if ( (event.key.keysym.unicode & 0xFF80) == 0 ) {
ch = event.key.keysym.unicode & 0x7F;
cout << ch;
if(isdigit(ch))
MessageBeep(0);
}
It beeps with the numbers over the letter keys, but it doesn’t with the rightmost numbers. Unicode
translation is ON, NumLock doesn’t make a difference and the sym path (assuming ascii) doesn’t work
either.

Thanks, Bruno Mart?nez

Which characters DOES it return when you press the numpad keys?

RK.

I don’t know the name but it’s that square that belongs to poker cards. It’s the same for all num-keys. It maybe different on other computers since I’ve
got a Spanish keyboard and live in South America. All’s properly configured anduer windows, tough (WinXP).

SDL_EnableUNICODE(1);
then use the keysym.unicode for the character…
read the SDL_keysym docs for how to trim the 16bit unicode down to ASCII.

then with numlock on you should get numbers…

Please tell me the NUMERIC value of fields in the ‘keysym’ structure in
the event for a few numpad keys.

BTW, it’s annoying when people reply to digests instead of in the
thread. Plz avoid if you can. 10q.
