Interface: BodyMotionHandle

Stateful handle returned by createBodyMotion. Owns the spin angle accumulator and writes the resulting orientation onto a target THREE.Group.

Properties

spinAngle

spinAngle: number;

Accumulated self-rotation angle (rad). Mutable for replay / scrub.

---

tick

tick: (dt) => void;

Advances spinAngle by the elapsed dt. The caller decides whether and when to call this — passing 0 (or skipping the call entirely) freezes the body's rotation, which is how "pause" is expressed without the lib needing to know about pause.

Parameters

Parameter	Type
dt	number

Returns

void

---

applyTo

applyTo: (group) => void;

Writes the current orientation onto a THREE.Group. Only the quaternion is touched — the group's world position is left untouched so the caller stays in charge of placing the body in the scene.

Parameters

Parameter	Type
group	Group

Returns

void
