Struct SkyRotationSystem 

pub struct SkyRotationSystem { /* private fields */ }

Advances the world’s celestial-sphere rotation on the fixed timestep.

Publishes the tick’s SkyOrientation and writes it onto the SkyRotation entity’s Transform, so the renderer, the lights and the transform hierarchy all read one rotation. Frozen while a world-pausing screen is open, like the rest of the simulation.

Implementations

impl SkyRotationSystem

pub fn new(rotation: &SkyRotation) -> Self

The system for a world’s authored rotation.

Trait Implementations

impl Debug for SkyRotationSystem

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

Formats the value using the given formatter.

impl System for SkyRotationSystem

fn init(&mut self, ctx: &mut PipelineContext<'_>)

Run once at World::start, before the first step.

fn step(&mut self, ctx: &mut PipelineContext<'_>) -> StepResult

Run once per tick.

fn access(&self) -> Access

The data step may touch, consulted once when the schedule is built (after init, so a data-dependent system can compute it from its compiled state). The default claims everything: an undeclared system is ordered against all others and never runs concurrently, which is always safe. Declaring narrower access is what admits a system to shared waves and to debug-build access validation.
