Struct SleepSystem 

pub struct SleepSystem {
    pub energy_threshold: f32,
    pub sleep_delay: f32,
    /* private fields */
}

Manages sleeping bodies to skip expensive simulation when at rest.

Fields

energy_threshold: f32

Kinetic energy threshold below which bodies become drowsy.

sleep_delay: f32

Time a body must remain below threshold before sleeping (seconds).

Implementations

impl SleepSystem

pub fn new(energy_threshold: f32, sleep_delay: f32) -> Self

pub fn update( &mut self, bodies: &mut HashMap<RigidBodyHandle, RigidBody>, dt: f32, ) -> Vec<RigidBodyHandle>

Update sleep states for all bodies. Returns handles that just went to sleep.

pub fn wake_body( &mut self, handle: RigidBodyHandle, bodies: &mut HashMap<RigidBodyHandle, RigidBody>, manifolds: &[ContactManifold3D], )

Wake a body and propagate to all bodies connected by contacts.

pub fn wake_in_region( &mut self, region_min: Vec3, region_max: Vec3, bodies: &mut HashMap<RigidBodyHandle, RigidBody>, manifolds: &[ContactManifold3D], )

Wake all bodies touching the given AABB.

pub fn sleeping_count( &self, bodies: &HashMap<RigidBodyHandle, RigidBody>, ) -> usize
