pub(crate) struct PhysicsEvents {
receiver: Receiver<CollisionEvent>,
collector: ChannelEventCollector,
velocities: Vec<(RigidBodyHandle, Vec3)>,
}Expand description
The event plumbing a physics world carries between steps.
Rapier reports contacts through channels: the collector it is stepped with owns the sending ends, and this component keeps the collector and the receiving end of the collision channel alive across steps, so each step reuses them instead of allocating fresh channels.
Fields§
§receiver: Receiver<CollisionEvent>§collector: ChannelEventCollector§velocities: Vec<(RigidBodyHandle, Vec3)>The moving bodies’ velocities, sampled before the step so a contact can be reported with the speed the pair was closing at.
Implementations§
Source§impl PhysicsEvents
impl PhysicsEvents
fn new() -> Self
Sourcefn sample_velocities(&mut self, physics: &PhysicsWorld)
fn sample_velocities(&mut self, physics: &PhysicsWorld)
Record the moving bodies’ velocities before the step runs.
Sourcefn velocity(&self, body: RigidBodyHandle) -> Vec3
fn velocity(&self, body: RigidBodyHandle) -> Vec3
The velocity a body had before the step, or zero if it was still.
