The way that you have your trigger set up. As long as you hold the trigger down the shooter will be set at 1 but if you let go of the trigger it will be set back at 0. Do you want the trigger to toggle the shooter on and off?

Can someone posta code for a toggle button or for an array of buttons that can change speeds with a press, not held down? This would be very help!

Thank you and Happy Competition!

Both toggle and cycle buttons are based on a button "press" instead of just being held down. To detect when a button is pressed:

// outside the "checking" loop
boolean prevState = false;

// inside checking loop; can be within continuous or periodic
boolean currentState = joy.getRawButton(DESIRED_BUTTON);
if(currentState && !prevState) {
    // Button DESIRED_BUTTON is newly pressed
    // Do stuff here
}
prevState = currentState;

To do a toggle, have an extra boolean (e.g. tracking), then when the button is pressed:

tracking = !tracking;

To do a cycle, have an int (e.g. basketChoice) and do this on button pressed:

basketChoice = (basketChoice+1)%NUM_CHOICES;

What can this do? Could this be used to add a ball count to the robot.

This is called modular arithmetic. You probably don't want to use that particular method for counting balls, because if, for example, your NUM_CHOICES were 3, then as balls enter the count would go 0,1,2,0,1,2, instead of 0,1,2,3,4 as they entered and 4,3,2,1,0 as they left.
