Help programming joystick buttons

We tried to use getRawButton in our code but every time we use it there is a problem.
if you could show us an example of a code using getRawButton that would be very helpful.

i dont get it. whats your problem

Joystick j = new Joystick(1);
JoystickButton a = new JoystickButton(j,1);
a.whileHeld(new YourCommand());

in command based or

Joystick j = new Joystick(1)
if(j.getRawButton(1)){
do stuff
}

in iterative. both will run when A is pressed

What kind of problem?

Here is an example of using getRawButton to switch between tank drive and arcade drive when the trigger (button one) on the left joystick is pressed.

    public void operatorControl() {
        chassis.setSafetyEnabled(true);
        
        if (leftStick.getRawButton(1))
        {
            chassis.tankDrive(leftStick, rightStick);
            Timer.delay(0.01);
        }
        else 
        {
            chassis.arcadeDrive(leftStick);
        }
    }

Also, in your original code, your autonomous code won't run because autonomous is misspelled.

Have you heard about command based programming? It is a lot cleaner and will help you avoid creating hundreds (okay, not hundreds) of "else if" blocks and actually set up a polymorphic structure and abstracting your code. It's a specifically tailored design pattern. It's probably too late now, but it's something you should consider next year: http://firstforge.wpi.edu/sf/docman/...tation/doc1297
