We need to think carefully on this as a '+10' combined with '-10' force will result in '0'; however we do not want to deactivate the wheel (no-resistance mode) as this will result in 'ticking' on the wheel as force transitions through 0.... ideally we'd need to know that there are no forces set.No problem Simon, this is thought about: If forces are active, and they cancel out, hid_lg4ff_start_combined is called with 0 force (scaled_x = 0x80), instead of hid_lg4ff_stop_combined as you assumed.Okay, so to set things straight: I should modify to patch to send 0x13 when the effect is fully stopped and use 0x11 0x80 to only zeroize the force when the overall force is zero? My DFP doesn't differentiate between these states so I cannot tell what is the right thing to do.
