problem with joy[] in allegro - syn9 - 01-17-2006

hi. i'm trying to use allegro's joystick routines, but whenever i try to access dat in joy[] the program crashes... heres the code i'm using. and before you ask why i'm not using sdl's joystick routines is because sdl wont deteck my joystick >)

Code:
#include once "sdl\sdl.bi"

#include once "allegro.bi"

allegro_init

install_joystick(JOY_TYPE_AUTODETECT)

print num_joysticks

dim event as SDL_Event, video as sdl_surface ptr

print "sdl_init"

if SDL_Init(SDL_INIT_VIDEO) < 0 THEN

    PRINT "could not init sdl: "; SDL_GetError

    end

end if

video = sdl_setvideomode(320, 240, 16, 0)

do

    sdl_pumpEvents

    poll_joystick

    while SDL_PollEvent(@event)

        select case event.type

        case SDL_KEYDOWN

            exit do

        end select

    wend

    if joy[0].button(0).b then print "button 1 pressed"

loop

sdl_quit

remove_joystick

allegro_exit

thanks!

v1c helped me out. heres his solution::

Quote:The "joy" global is incorrectly declared in inc/allegro.bi, change it to:

Code:
Extern Import joy(0 to MAX_JOYSTICKS-1) Alias "joy" As JOYSTICK_INFO

At line 1157.

Access it using array indexing after that, not pointer indexing.
