Crate concinnity_physics 

Concinnity physics: the engine’s rigid-body simulation and the vocabulary it is driven through, in its own crate so it names no engine domain type. It provides the shapes, body parameters, joints, layer masks, and step results that cross the boundary between a caller and the Simulation, and the PhysicsBudget a world reserves its bodies against.

Everything crossing that boundary is plain data in the engine’s [f32; 3] and Euler-degree representation, addressed by an opaque BodyHandle. That is what lets the simulation hold whatever math types it likes without those types reaching a caller.

Structs

BodyHandle

Opaque handle to a body inside a simulation.

CharacterCapsule

A character’s collision capsule: a cylinder of 2 * half_height capped by hemispheres of radius, standing on the y axis.

CharacterMove

Result of moving a character capsule for one tick.

CharacterMoveInput

One character-capsule move request.

ContactHit

One contact strong enough to pass the simulation’s force threshold.

DynamicParams

Physical parameters for a dynamic (freely simulated) body.

Inline

The fan-out for a caller that has no threads to lend: every unit runs on the calling thread, in order.

JointMotor

Velocity-driven motor parameters for a revolute or prismatic joint.

LayerMask

Membership and filter bits applied to a collider or query.

PhysicsBudget

The reservation a world’s physics content implies.

PhysicsCounts

Tallies of a world’s authored physics content.

RayHit

One raycast hit: the surface point, its outward normal, and the distance from the ray origin.

SensorCrossing

One boundary crossing of a sensor region recorded during a step: something began or stopped overlapping the sensor tagged tag.

ShapeCast

A shape swept through the world along a straight line.

ShapeCastHit

What a ShapeCast ran into.

SimConfig

Tuning for one simulation.

Simulation

A rigid-body simulation: bodies fall under gravity, collide, and come to rest.

Enums

ColliderShape

A collision shape, in the body’s local space.

JointSpec

Constraint shape connecting two bodies.

Constants

GRAVITY

Acceleration due to gravity in world units per second squared. Shared with the third-person controller so its jump takeoff matches the rig’s fall.

Traits

Fanout

A caller’s way of running independent work at the same time.

Functions

euler_deg_from_quat

Engine Euler degrees [pitch, yaw, roll] for an [x, y, z, w] rotation quaternion, which need not be normalised.

quat_from_euler_deg

The [x, y, z, w] rotation quaternion for engine Euler degrees [pitch, yaw, roll], applied in YXZ order.
