Programming a super shifter/gearbox

In this case, the CIM motors are programmed exactly the same as a regular single speed gearbox. Then program your desired trigger button on the joystick to control the solenoid. Drive without the button pressed, and it is in low gear. Press and hold the trigger button, it shifts to high gear.

That makes a lot of sense. But this isnt a pneumatic so theres no solenoid. its just a small piece that moves up down. and changes from a smaller gear to a higher gear. I understand the theory behind it I just don't know what the class is for the gear box. It plugs in where the jaguars go but I think I would encounter problems if I programmed it as a jaguar. (sorry im a little confused about this because the electronics team doesnt really know how to put this together.)

You are describing a servo. So you would program this as a servo object presuming it is like or is a Hitec HS-322

Thank you so much sir. You are a gentleman and a scholar so...

Servo supershifter = new servo (1); ?
Then how would I set it to change between gears?

I myself use the set() method so here's some java pseudo code for controlling it with joystick buttons. This assumes you want the servo to go through the full range of motion from 0 to 1. There is also a setAngle() method you could use.

if (buttonIsPressed()) {
    servo.set(1);
} else if (anotherButtonIsPressed()) {
    servo.set(0);
}

I figured it was that so I had put it in and it told me it was wrong. then I realized i forgot to capitalize servo. -_- gotta love programming.
