Host-side logs proved the macOS client sent keyboard + scroll but ZERO relative
mouse-motion and ZERO button events for an entire session — the user was moving
the mouse the whole time. Root cause is client-side: GCMouse's
mouseMovedHandler/pressedChangedHandler silently never fired on the live Mac
(a documented GameController quirk) while GCKeyboard worked and scroll already
rode NSEvent. So motion/buttons were the only input on a GCMouse-only path, and
that path was dead.
macOS: stop relying on GCMouse for motion/buttons (compiled out with
#if !os(macOS)); drive them from a local NSEvent monitor installed only while
captured — the same channel scrollWheel already uses successfully. Under
CGAssociateMouseAndMouseCursorPosition(false) the mouseMoved/dragged deltaX/deltaY
ARE the relative motion (OS-acceleration-applied, exactly what Moonlight's macOS
client ships). All four motion event types are covered so motion keeps flowing
during a button-held drag; buttons map left/right/middle/X1/X2 through the
existing engage-click-suppression + release-on-blur logic. NSEvent deltaY is
already screen-space (+y down) so, unlike the GCMouse path, it is NOT negated.
iPad: the input failure there was a different cause — GCMouse only delivers
relative deltas while the scene holds a true pointer LOCK, which the system grants
only to a full-screen, frontmost iPad scene and which UIHostingController doesn't
consult for children. Gate prefersPointerLocked to iPad + captured, add
childViewControllerForPointerLock so a reparenting container forwards the lock
decision to this VC, and log the resolved lock state. Touch remains the
unconditional fallback.
Adds a PUNKTFUNK_INPUT_DEBUG=1 switch (os.Logger, throttled) so motion/buttons
being SENT is verifiable on-device without host-side logs. iOS GCMouse path
otherwise unchanged; GCKeyboard unchanged on both. Researched + adversarially
reviewed; Swift builds only on a Mac, so this is unverified-compiled here.
