First of all may i say that the work you guys have done on Haiku is
incredible, I installed it on my system a few weeks ago and it just
feels exactly like BeOS 'which of course is the idea :-)'. Amazing
work everyone. I did help out a bit a long time ago with DirectWindow
and Windowscreen along with Jack Burton(Stefano).
Now onto the joystick stuff, i have read on the list that a lot of
work has already been done on the joystick framework. I fired up my
old BeOS system and did some work to try and see how BeOS BJoystick
really worked.
There is a high probability that some of the things i mention are
already known, so forgive me for that. I know that _joystick_info has
already been created in joysticktweaker but i'm confident that the
following is correct.
Here is how the BJoystick _joystick_info *m_info is arranged,
struct button_names {
const char *name;
};
struct axis_names {
const char *name;
};
struct hat_names {
const char *name;
};
struct _joystick_info { // size 0x428 (1064) bytes
_joystick_module_info module_info;
_extended_joystick sticks[4]; // offset 0x100 // correct
char file_name[256]; // offset 0x1b0 // correct
axis_names axis_name[12]; // offset 0x2b0 // correct
hat_names hat_name[8]; // offset 0x2e0 // correct
button_names button_name[32]; // offset 0x300 // correct
_extended_calibration calib[4]; // these are not correct
char dummy[36]; // not correct
// the above items are to do with calibration but i don't know
exactly how they work yet
bool calibration_enabled; // offset 0x424 // correct
};
