Accessors

hasCandidates

get hasCandidates(): boolean
Returns true if any fast-moving bodies were registered in the current substep.

Returns boolean

Methods

checkCandidate

checkCandidate(
    obj: Object3D,
    deltaP: Vector3D,
    ccdMotionThreshold: number,
): void
Tests whether a moving body exceeds the motion threshold and should be registered for swept CCD.
Parameters
- obj: Object3D
  The dynamic Object3D.
- deltaP: Vector3D
  Positional displacement vector for this substep.
- ccdMotionThreshold: number
  Multiplier of broad radius triggering CCD.
Returns void
- Defined in physix/ccd/SweptSphereCCD.ts:40

resolve

resolve(broadphase: PhysicsBroadphase): Object3D[]
Sweeps all registered CCD candidates against nearby colliders and clamps their positions to earliest impact.

Callers must reset the broadphase placement of every returned body afterwards (e.g. PhysicsBroadphase.reinsertCollider): a clamped position behind the swept one is no longer represented by the octree node it was originally inserted into (that node covers the unclamped swept volume), so later queries around the body's actual position would silently miss it.
Parameters
- broadphase: PhysicsBroadphase
  The active physics broadphase structure.
Returns Object3D[]
The bodies whose positions were clamped this call.
