commands activated by trigger, how?

If you take a look at the javadoc for the Joystick class, then look at the getTrigger() method, you'll see that it doesn't return a boolean value.

The triggers on the logitech (and xbox if I remember correctly) are on axis 3.

The getTrigger method does return a boolean. The trigger on the Logitech Attack 3 Joystick is button 1.

To use the trigger treat it exactly like a button.

You're right, I was thinking about the the Logitech F310... and I apparently can't read the javdoc I linked lol.

Well what I posted earlier is applicable to using using axes as buttons if anyone needs that lol.

Thank you very much! I couldn't find anything saying it was actually just button 1 and didn't realize that in all the documentation that button one was never listed(just trigger).

The first step I would recommend when using any USB input device for FRC is to document the button and axis mapping and ranges. The easiest way to do this is to (on Windows 7, XP may or may not vary slightly):

1. Click the Start Menu
2. In the run box type "joy.cpl" and press Enter
3. Select the desired device from the list and click Properties
4. Select the Test tab if it is not selected already

The X axis (horizontal) and Y axis (vertical) are represented by the crosshair in the box. Axes 3-6 are represented in order, top to bottom, by bars to the right of the box. The buttons are represented below and light up when pressed. The first 6 axes (including X/Y) and 12 buttons will be transmitted, if your device has more they will be ignored.

There is online documentation for CommandBased programming, in particular this link shows how to attach commands to a joystick.

Joystick DriveStick = new Joystick(1);
Button button = new JoystickButton(joystick, BUTTON_NUMBER);
public OI() {
    button.whenPressed(new LauncherSpinWheels());
    // ...
}

Replace BUTTON_NUMBER with the button you want to run the command.

In addition to the online documentation, you might find these videos helpful if you're having trouble understanding CommandBasedProgram.:
