button: PointerButton

Release

Pointer released, always. PickEvent::Click is gated behind click_within_slop_dp, so a drag that ends far from where it started emits no click at all; a game that drags something has no other way to learn that the drag ended. Emitted before PickEvent::Click, and whether or not a click follows.

Window-physical px (y-down), same space as Press.screen. Games stage this raw and unproject through the live camera each frame (screen-anchored aim); the world point is baked through the camera at event time and goes stale as the camera moves.

TouchDown

Touch/pen contact began: pointer id + window-physical px. Mouse does not emit these; taps still emit Click too.

Fields

id: u64

screen: [f32; 2]

TouchMove

Touch/pen contact moved (same coordinate space as TouchDown).

Fields

id: u64
