Struct PointerSystem 

pub struct PointerSystem { /* private fields */ }

Runtime owner for pointer-specific state and lifecycle.

Initial responsibilities:

• ensure each PointerComponent owns a child RayCastComponent
• cache pointer ↔ raycaster relationships

Higher-level pointer behavior (topology classification, trigger policy, etc.) will migrate here incrementally from other systems.

Implementations

impl PointerSystem

pub fn register_pointer( &mut self, world: &mut World, component: ComponentId, emit: &mut dyn SignalEmitter, )

pub fn remove_pointer(&mut self, component: ComponentId)

pub fn raycast_for_pointer(&self, component: ComponentId) -> Option<ComponentId>

pub fn raycast_to_pointer(&self, raycaster: ComponentId) -> Option<ComponentId>

impl PointerSystem

pub fn build_activations( &self, world: &World, input: &InputState, xr: &XrInputState, ) -> PointerActivations

Map each registered pointer to its trigger state this frame.

Desktop pointers use InputState mouse left button. Controller-backed pointers use XrInputState indexed by hand. A gaze-style pointer beneath CameraXR has no implicit trigger source and must not consume desktop mouse input merely because it lacks a ControllerXR ancestor.

Trait Implementations

impl Debug for PointerSystem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PointerSystem

fn default() -> PointerSystem

Returns the “default value” for a type.
