BodyMover

BodyMover is the abstract base class for the set of legacy objects that exert forces to assemblies in different ways. In general, the subclasses of BodyMover are:

• BodyForce exerts a force relative to world coordinates.
• BodyPosition exerts force to maintain a certain world position.
• BodyVelocity exerts force to maintain a certain velocity.
• BodyThrust exerts a force relative to object coordinates which applies torque if positioned in a certain way.
• BodyGyro exerts torque to maintain a certain orientation.
• BodyAngularVelocity exerts torque to maintain a certain angular velocity.
• RocketPropulsion exerts both translational and rotational forces to cause an assembly to track down another.
