Omni-Directional 200 mm Wheels

Second year of VexIQ with 4/5 grades. We recently upgraded to Omni-Directional Wheels. Our wheels are on, but how do we make it compatible with the joysticks?

Are you using 2 omni wheels and 2 regular wheels? Or a different drive like holonomic or H Drive?
If you just have the 2 wheels, you don’t need different code.
