Struct SceneHandles 

pub struct SceneHandles {
    pub physics: WorldHandle,
    pub audio: WorldHandle,
    pub gameplay: WorldHandle,
    pub refresh_millihertz: Arc<AtomicU32>,
}

The scene’s worlds, however they are driven.

Every world is a host entity carrying the runner’s proxy, so the host’s data is the same whether the worlds run on threads or the host steps them; only who calls their ticks differs. What the objects reach them through is a Scene, built beside them and handed to every tick.

Fields

physics: WorldHandle

The rapier world.

audio: WorldHandle

The synthesizer’s world.

gameplay: WorldHandle

The world the scene’s objects live in; its sender is the control panel’s handle on them.

refresh_millihertz: Arc<AtomicU32>

The refresh rate of the display the window is on, in millihertz, as the frame loop last read it; zero until a window reports one.

It paces the gameplay thread, nothing else: a tick’s duration is the one it measured, so a stale rate only makes the thread wake more or less often than the display redraws.

Trait Implementations

fn clone(&self) -> Self
