So we've been trying to get rid of Digital IO Buttons and use the Xbox controller for our operator. I've found from searching that the Xbox controller can be called as a Joystick, and the A, B, X, and Y buttons, Right Stick Button, Left Stick Button, and the Bumpers can be called as JoystickButtons. Also the two sticks, the triggers, and the D-Pad are six axes of the Joystick, however, the D-Pad is extremely glitchy. I'm trying to use the triggers to activate a cylinder in the OI, where all of the other buttons activate commands. Here's the code from in the OI.java

if(xBox.getRawAxis(3)>0.5){
Robot.catcher.clamp=true;
}
else if(xBox.getRawAxis(3)<0.5){
Robot.catcher.clamp=false;
}

Does anyone know why this won't fire the cylinder? (I don't have the code with me so if the cylinder code isn't right here, sorry, I know it's right in the actual code)
