Logitech F310 Control Scheme Help

[Timothyw0]

Hey guys,
So my team decided to switch to Java programming this year since we want to edge away from the basics of Labview. Everything's going swell so far however we encountered an issue with the control scheme that our drive team is used to. Our drive team uses the gamepad in a fps-like sense. The left joystick is utilized to move the robot forward and backwards while the right joystick is used to rotate the robot. Much like an fps, the controller's joysticks would be used in multiple directions to move the robot forward while turning a slight bit. Our programming team has worked tremendously hard on creating a formula to get this to work but we can't seem to get it. Could you guys possibly help us at all? Thanks!
