Can SDL detect and use multiple USB mice in a multiplatform way?

SDL Development
1

Is there a way to use multiple USB mice within SDL, without having to
resort to system-specific (X11/DirectX) code? Based on the way the API
is described in the SDL documentation, I would guess the answer is no.
Could someone please prove me wrong :slight_smile:

In case anyone was wondering, I’m planning on using multiple
mice/trackballs as multiple paddles for the Atari 2600 emulator,
Stella. It would be so nice if SDL detected them, and even nicer if it
worked multi-platform (Windows and Linux, and possibly MacOS).

Thanks,
Steve

No, this sort of stuff is very platform dependent. You need a device entries
for every mice under X11.

What? The entire purpose of SDL is to abstract things that are very
platform dependent.

I’d expect the demand for this particular feature is far too small.On Sat, Mar 20, 2004 at 08:07:48PM -0800, Die Nacht! wrote:

I’d like such a feature, so that I could make a particular 2 players
game…

That’s right though that such a feature has rarely been used. The only
example I can think of is Lemmings (on the Amiga).On 21/03/2004, Glenn Maynard, you wrote:

No, SDL currently doesn’t support multiple mice.

See ya!
