This should more closely match the algorithm used by native, discovered through extensive manual testing.
This does not include any automated tests, both because I could not get winmm to recognize a second plugged joystick, and (as I eventually discovered while testing) the number of tests that would be necessary to conclusively prove this algorithm turned out to be impractical.
--
I discovered that a certain joystick, an XBox clone (Logitech F310) was failing to report all of its axes to a winmm game (Super Smash Flash 2). The joystick reports axes X, Y, Z, RX, RY, RZ, but currently winmm does not map RY.
Checking Windows's joy.cpl implied that our HID usages were correct, so I instead started checking whether our mapping algorithm was correct for a synthetic joystick with the same usages.
It turned out that it was not. Native winmm appears to work in a way that is relatively intuitive to understand: for each axis, it runs through a list of candidate usages. If the candidate usage is present on the joystick, and wasn't already mapped to a different axis, then the axis is mapped. --- dlls/dinput/tests/joystick8.c | 16 +-- dlls/winmm/joystick.c | 203 ++++++++++++++++++++++------------ 2 files changed, 140 insertions(+), 79 deletions(-)
