ReadonlyanchorsWhether the body-local anchors changed and have not reached the solver yet (PH-22f, 2026-09-06).
ReadonlycollisionWhether collisionEnabled changed and has not reached the solver yet
(PH-22f, 2026-08-08).
ReadonlylimitsWhether the limits changed and have not reached the solver yet.
ReadonlymotorWhether the motor changed and has not reached the solver yet.
What a joint has been asked to reconfigure since the world last drained it (§28; the §26 command pattern applied to constraints).
A live read-only view of joint-owned storage.
PhysicsWorldconsumes it once per fixed step, pushes the current HingeJoint.limits, HingeJoint.motor, Joint.collisionEnabled, and Joint.anchorA / Joint.anchorB intoSolverJointAccess, and clears it — so a joint reconfigured three times between steps costs one solver call, with the last value winning.
