Struct BallDrops 

pub(super) struct BallDrops {
    balls: Balls,
    scene: Scene,
}

The balls and the tick that drops, poses and sweeps them, spawned together.

The balls hold no world of their own: every instance, body and pose is asked of the worlds the tick is handed, so a state spawned without its tick would hold streams nobody reads.

The tick reads the scene’s assets, which the build in the default band writes, so it states BALLS_ORDER: two behaviours in one band have no order between them, and the read would find no assets.

Fields

balls: Balls

The state the tick advances.

scene: Scene

The worlds the balls ask their instances, bodies and poses from.

Implementations

fn tick(balls: &mut Balls, world: &World, scene: &Scene, delta_seconds: f32)

Advance the balls by one tick: fold the answers, drop, pose and sweep.
