Blitz Basic 2.1 problem with reading a CD32 joypad

[Graham Humphrey]

I've been working on a game recently and it's not that far off being finished but I've hit a bit of a stumbling block. It's a multiplayer game and as well as being able to use a joystick adaptor, there is also a padshare option allowing two players to use one pad - it has to be a CD32 pad though so there is enough buttons available.

Anyway Blitz has a command to read buttons on a CD32 pad called Gameb. You use it thus: Gameb (Port#) where of course port is 0 (mouse port) or 1. When I check the pad in port 1 it works fine and reads all the buttons without a problem. But when I try it in port 0, with the exact same code only I've changed the 'Port' number, it won't read the buttons at all except for the left shoulder button, curiously.

Is this a bug with Blitz I wonder? It isn't my pad because it works fine in port 1 with my game, and it isn't my mouse port as I tested it with Base Jumpers CD32 and the padshare option worked perfectly in port 0. And it's not my code because as I said, it works fine in port 1 but as soon as I change all the 1s to 0s it goes bonkers.

Any ideas? Does the latest Amiblitz do the same thing?

It's not Graham's hardware, because the game acts the exact same way on my A1200 too. I hope someone can help!

[Graham Humphrey]

I'll have to give AmiBlitz a whirl I think... that is unless somebody can conjure up a solution

You could do it directly using asm or even the system includes!

[Graham Humphrey]

I could do but my ASM knowledge is nil, likewise for the system includes. Looks like more stuff to get my head around

Hey this is interesting Graham - a new amiga game?

[Graham Humphrey]

Yes

More details to follow soon

[Graham Humphrey]

Just tried it on (the gargantually appalling) AmiBlitz 3 (when it didn't crash) and exactly the same thing happened so it looks like I'm stuck for the time being

Have a look at the RI Blitzlibs (part of the old Blitz support suite), IIRC there was a command lib in them for querying joysticks & joypads.

If your version of Blitz is so old that they're not included, aminet has them http://aminet.net/package/dev/basic/RIBlitzLibs
