Implementations

impl GestureSystem

pub fn begin_frame(&mut self)

pub fn install_handlers(&mut self, rx: &mut RxWorld)

Install drain-point handlers into RxWorld.

pub fn state(&self) -> &GestureState

Returns the gesture state for the first active pointer, for callers that only care about a single pointer (e.g. editor gizmos, cursor 3D).

pub fn set_drag_update_policy(&mut self, policy: DragUpdatePolicy)

pub fn tick_with_rx( &mut self, visuals: &VisualWorld, input: &InputState, activations: &PointerActivations, pointer_system: &PointerSystem, rx: &mut RxWorld, )

Consume RayIntersected signals and PointerActivations to emit DragStart/DragMove/DragEnd/Click.

input is still passed for cursor_pos (screen-space fields on desktop pointer events). activations drives press/down/release for each pointer regardless of input source.
