BodyMover

BodyMover is the abstract base class for the set of legacy objects that exert forces to BaseParts in different ways. In general, the subclasses of BodyMover can be placed into one of two categories based on the type of force(s) they exert:

Translational Force

• BodyForce: Exert a force relative to world coordinates
• BodyPosition: Exert force to maintain a certain world position
• BodyVelocity: Exert force to maintain a certain velocity

Rotational Force (Torque)

• BodyThrust: Exert a force relative to object coordinates, which applies torque if positioned in a certain way
• BodyGyro: Exert torque to maintain a certain orientation
• BodyAngularVelocity: Exert torque to maintain a certain angular velocity

An exception is the RocketPropulsion class, which exerts both translational and rotational forces to cause a part to track down another part.
