So I want to bind the controls of a keyboard to a gamepad. So the mouse and keyboard will be completely unusable.
I want to be able to change say, my radar to my binoculars. And the way to do that would be holding down a button, and my inventory would pop up. And as you hold down the inventory button you can scroll through it with left analogue stick (tilt left or right on analogue stick).
And say If I want to switch from Radar to Map, when I change to map, my HUD with radar changes to HUD with Map.

So how could I go about changing from one thing in my inventory to another through a scrolling HUD menu
