Implementations

impl CameraSystem

pub fn new() -> Self

pub fn register_camera( &mut self, world: &mut World, visuals: &mut VisualWorld, component: ComponentId, ) -> CameraHandle

Registers a camera derived from the component tree.

The newest registered camera becomes active.

pub fn set_active_window_camera( &mut self, visuals: &mut VisualWorld, h: CameraHandle, )

pub fn set_active_xr_camera( &mut self, world: &World, visuals: &mut VisualWorld, component: ComponentId, )

pub fn update_camera_2d_from_parent_transform( &mut self, world: &World, visuals: &mut VisualWorld, camera2d_component_id: ComponentId, transform_component_id: ComponentId, )

Update Camera2D view/proj from the component tree.

camera2d_component_id should be the Camera2DComponent, whose parent is typically a TransformComponent.

pub fn register_camera2d( &mut self, _world: &mut World, _visuals: &mut VisualWorld, component: ComponentId, ) -> CameraHandle

Register a Camera2D component.

pub fn active_window_camera_matrices( &self, ) -> Option<([[f32; 4]; 4], [[f32; 4]; 4])>

pub fn has_active_window_camera(&self) -> bool

pub fn update_camera_3d_from_parent_transform( &mut self, world: &World, visuals: &mut VisualWorld, camera3d_component_id: ComponentId, transform_component_id: ComponentId, )

Update Camera3D view/proj from the component tree.

camera3d_component_id should be the Camera3DComponent, whose parent is typically a TransformComponent.
