Struct PhysicsSystem 

pub struct PhysicsSystem { /* private fields */ }

Rigid-body simulation behavior. Constructed internally by World::start from the world’s PhysicsConfig; never a declarable asset.

new steps the simulation on the calling thread; a host lends it threads through with_fanout.

Implementations

impl PhysicsSystem

pub fn new(config: PhysicsConfig) -> Self

Build the simulation from the world’s PhysicsConfig (floor / terrain). Bodies and colliders are added from the ECS in System::init.

pub fn with_fanout(self, fanout: Box<dyn PhysicsFanout>) -> Self

Run the step’s independent work through fanout rather than on the calling thread. What a step hands out and the order its results load back in are the simulation’s; a fan-out decides only where the work runs, so this cannot change the state a tick lands on.

Trait Implementations

impl Debug for PhysicsSystem

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

Formats the value using the given formatter.

impl System for PhysicsSystem

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.
