Struct Camera3DSystem 

pub struct Camera3DSystem { /* private fields */ }

First-person / fly-through controller behavior. Constructed internally by World::start from the controlling Camera3D’s CameraController; never a world-declared asset.

Implementations

impl Camera3DSystem

pub fn reset_velocity(&mut self)

Zero the smoothed movement velocity. Called when an external source (the cn debug camera-set command) teleports the camera, so free-fly velocity integration does not drift the new pose on the next step. Only reached from the binary-only debug drive, hence dead in a --lib build.

Trait Implementations

impl Debug for Camera3DSystem

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

Formats the value using the given formatter.

impl System for Camera3DSystem

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.

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.
