Sets whether the translation of the PrismaticConstraint is actuated and, if so, what kind of actuation.

If ActuatorType is set to None, then the joint can slide freely:

If ActuatorType is set to Motor, then the PrismaticConstraint will attempt to move its Attachment at a constant velocity specified by SlidingBallConstraint/Velocity. The PrismaticConstraint will apply a force up to SlidingBallConstraint/MotorMaxForce to achieve the desired velocity but will be limited by SlidingBallConstraint/MotorMaxAcceleration.

If ActuatorType is set to Servo, then the PrismaticConstraint will attempt to move its Attachments to an offset specified by SlidingBallConstraint/TargetPosition. The PrismaticConstraint will attempt to translate towards that goal at a target speed set by SlidingBallConstraint/Speed. The maximum force the PrismaticConstraint is allowed to use to meet these goals is set by SlidingBallConstraint/ServoMaxForce.
