Values from the joystick are continuous, so a value of 0.3 when pushing an axis forward slightly is reasonable.

We typically output the values so they can be viewed in NetConsole, like this:


System.out.println("X: " + joystick.getX() + ", Y: " + joystick.getY() + ", Rot: " + joystick.getTwist() );

However, we found out (we switched to java this year, it used to work in C++) that the getRotate() didn't work as we expected, so instead we use

double rotate = joystick.getRawAxis(4);

In fact, joystick.getTwist() for us was returning 0 until we moved it a bit, then it'd be stuck at 1. Not sure what's going on there....
