Struct Scene 

pub struct Scene {
    pub render: JobSender,
    pub physics: JobSender,
    pub audio: JobSender,
    pub poses: SnapshotReader<GamePhysics>,
    pub render_state: SnapshotReader<WorldState>,
    pub physics_state: SnapshotReader<WorldState>,
    pub audio_state: SnapshotReader<WorldState>,
}

The other worlds, as the scene’s objects reach them.

A tick hands one to every object, so an object names the world it wants instead of keeping a channel of its own. The ports are plain senders: what an object says to another world is a job, and what it learns back is a subscription — poses is the physics world’s, collected between its steps. Each subscription belongs to the world it reads, so a run that never asks for a snapshot pays nothing for it.

A port also carries what its world is doing: render_state, physics_state and audio_state are how an object that asked a question learns that the world it asked is gone, instead of waiting for an answer that will never come.

Both run modes build one from the worlds they have — threaded worlds for the windowed show, stepped worlds for the headless capture — and both then spawn the same objects with it, so the wiring is written once.

Fields

render: JobSender

Commands into the render world: the objects build their scene and move their instances through them.

physics: JobSender

Commands into the physics world.

audio: JobSender

Commands into the audio world.

poses: SnapshotReader<GamePhysics>

The physics world’s latest pose snapshot.

render_state: SnapshotReader<WorldState>

Whether the render world is still running.

physics_state: SnapshotReader<WorldState>

Whether the physics world is still running.

audio_state: SnapshotReader<WorldState>

Whether the audio world is still running.

Trait Implementations
