rc::Retracts

If you want to control a retractable landing gear on your scale model, you may use the Retracts class to finely control the motion of landing gear servos. The Retracts class supports three different setups:

-Single servo, no doors. In this setup there is just one servo controlling just the landing gear. If there are doors then the doors will open mechanically together with the landing gear.

-Single servo with doors. In this setup one half of the throw of the servo is used to control the doors, the other half is used to control the landing gear.

-Dual servo. This setup has a separate servo for the doors and the gear.

The Retracts class works with a timeline internally. Actions on the door and gear are mapped on this timeline and the timeline may be traveled in both directions. It's possible to specify the time the doors and gear should take to move separately. It's also possible to specify a delay between the movement of the doors and gear. This delay may be negative as to cause an overlap in movement between the two servos.
