Since the proper axes are specific and these elements should only be mapped to unused axes, I think they should be enumerated in a separate pass after everything else has had a shot. Note that collect_joystick_elements() is recursive, so it's not right to do it in a separate loop within collect_joystick_elements(). Probably, you'll want to call it twice from open_joystick(), with a flag to indicate which mode it should operate in.</blockquote><div class=""><br class=""></div><div class="">This where the Microsoft source documentation get *really* fuzzy. There are all sorts of possible mappings in the rare case where there is both a HID/Dinput Z-axis and a slider/dial/wheel. Microsoft gave 4-5 different variations of how it could go and in some of these mappings, the slider would take precedence over the reported HID Z-axis when mapping to the Winmm Z-axis such that slider -> WinmmZ is correct and the HID Z-axis is then ignored. So I decided to follow the Linux Winmm version and simply have whichever element is listed by the joystick first, wins. If it is the axis, it's the axis, if it is the slider, it's the slider. This actually is one of the ways Microsoft says to decide proper HID mappings to Winmm (and it seems like that for the elements within a joystick, the elements are always reported in the same order such that a user shouldn't experience the axes mappings changing each time they start up Wine/reconnect a device*). There is no 1 correct mapping for all cases. I guess ideally we would have a way of allowing the user to remap the joystick axes in the registry (maybe that would work even now? I don't know - I've seen some emails on that already in the wine-devel list serve but I don't know what the status of that kind of capability is) but even Microsoft states on of their pages that this is a pretty rare corner case.</div></div></div></div></div></blockquote><div><br class=""></div><div>OK, fine by me.</div><div><br class=""></div><br class=""><blockquote type="cite" class=""><div dir="ltr" class=""><div class="gmail_extra"><div class="gmail_quote"><div class="">*Note: in my testing this is *not* the same for OS X (I guess macOS now) reporting back devices - which human interface device is reported first seems to be random in my testing when I had both a virtual and physical joystick setup. Historically Winmm games would only take input from the first reported device - under Mac-Wine, I've noticed the games seem to be taking input from both my physical and virtual joysticks (sometimes regardless of what the game was saying it was doing!). This has both good and bad potential and is not necessarily behavior we should spend effort trying to get rid of. Not sure how the Linux version behaves in this situation in terms of joystick order and input from multiple sources. </div></div></div></div></blockquote><br class=""></div><div>It was taking input from both joysticks in the same run?
