Struct ManipulationSystem 

pub struct ManipulationSystem { /* private fields */ }

Built-in manipulation system for super::super::ViewportRuntime.

Wraps ManipulationController and drives it each frame from RuntimeFrameContext inputs. Handles G/R/S key sessions and gizmo drag. Writes transform changes via TransformWriteback; does not mutate the scene directly.

To suppress orbit while a session is active, check ViewportRuntime::is_manipulating before calling OrbitCameraController::apply_to_camera.

Implementations

impl ManipulationSystem

pub fn new() -> Self

pub fn gizmo_center(&self) -> Option<Vec3>

World-space center of the current selection, or None if selection is empty.

pub fn gizmo_scale(&self) -> f32

Screen-size scale factor for the gizmo arms.

pub fn gizmo_mode(&self) -> GizmoMode

Current gizmo mode (Translate / Rotate / Scale).

pub fn gizmo_hovered(&self) -> GizmoAxis

Currently hovered gizmo axis.

pub fn gizmo_info(&self) -> Option<GizmoInfo>
