OptionalfixedThe fixed step, in seconds (§7a, §10), that the inherited difference is divided by.
Omit it and the world uses the deltaSeconds of its last
PhysicsWorld.step, which is the fixed delta the target history was
actually captured across. It is only needed when no step has run yet — a
body activated before the first step of the simulation — or when a caller
knows the application's fixed delta better than the world does. Ignored
entirely without BodyControlModeOptions.inheritVelocityFrom.
OptionalinheritA PoseTarget (§19, plan P7-1) whose one-step history seeds the body's
velocities as part of the switch — "the ragdoll keeps the motion the
animation had".
The component's position/previousPosition and
rotation/previousRotation pair is finite-differenced over the fixed
step; see PhysicsWorld.setBodyControlMode for the exact formula and
for which target types accept it.
OptionalwakeWhether the switch wakes a sleeping body (§32). Defaults to true, which
is what activating a body means; pass false to re-type without disturbing
the sleep state.
How PhysicsWorld.setBodyControlMode performs a §19 control-mode transition (plan P7-3).
Every field is optional: the bare call re-types the body, wakes it, and seeds nothing.
