Hello,
I have been unable to get haptics to work in SDL 2.0 on Windows 7. The
call to IDirectInputDevice8_CreateEffect in SDL_SYS_HapticNewEffect in
SDL_syshaptic.c is returning E_INVALIDARG. The rgdwAxes member of the
DIEFFECT was the problem. I think this is because the DIEFF_OBJECTOFFSETS
flag is set, so the rgdwAxes should be offsets instead of object ids. I’ve
attached a patch that works for me.

Nice catch - are the axes guaranteed to map to those DIJOFS_[XYZ] axes? Should we be looking at the guid in DI_DeviceObjectCallback to see which axis it is, or something along those lines?

I recommend attaching this patch to a bugzilla entry, so that it won’t
be lost in the mailing list.
