Release Object: Release an object that has been picked. This object will no longer behave like shuttle. The picked number will be subtracted by 1.
Picked Number: The number of objected that has been picked by shuttle.
Range:How far will the shuttle travel before it goes the other way.
Delay Time:The time for the motor to pause before it starts rotating again.
Mutiply Speed: Dragging this slider will make the picked objects move even faster
When applied for the first time, Shuttle is set as a dynamic physics object slider constrained to the world. Its limited is set to the range that you set. You can change its slider constraint target from the constraint panel.
