Syntax

public struct GamepadState : IInputStateTypeInfo

Remarks

Be aware that unlike some other devices such as Mouse or Touchscreen, gamepad devices tend to have wildly varying state formats, i.e. forms in which they internally store their input data. In practice, even on the same platform gamepads will often store their data in different formats. This means that GamepadState will often not be the format in which a particular gamepad (such as XInputController, for example) stores its data.

If your gamepad data is arriving in a different format, you should extend the "Gamepad" layout and customize its Controls.

A real-world example of this is the Xbox Controller on macOS, which is supported through HID. Its layout looks like this:

{
    "name" : "XboxGamepadOSX",
    "extend" : "Gamepad",
    "format" : "HID",
    "device" : { "interface" : "HID", "product" : "Xbox.*Controller" },
    "controls" : [
        { "name" : "leftShoulder", "offset" : 2, "bit" : 8 },
        { "name" : "rightShoulder", "offset" : 2, "bit" : 9 },
        { "name" : "leftStickPress", "offset" : 2, "bit" : 14 },
        { "name" : "rightStickPress", "offset" : 2, "bit" : 15 },
        { "name" : "buttonSouth", "offset" : 2, "bit" : 12 },
        { "name" : "buttonEast", "offset" : 2, "bit" : 13 },
        { "name" : "buttonWest", "offset" : 2, "bit" : 14 },
        { "name" : "buttonNorth", "offset" : 2, "bit" : 15 },
        { "name" : "dpad", "offset" : 2 },
        { "name" : "dpad/up", "offset" : 0, "bit" : 8 },
        { "name" : "dpad/down", "offset" : 0, "bit" : 9 },
        { "name" : "dpad/left", "offset" : 0, "bit" : 10 },
        { "name" : "dpad/right", "offset" : 0, "bit" : 11 },
        { "name" : "start", "offset" : 2, "bit" : 4 },
        { "name" : "select", "offset" : 2, "bit" : 5 },
        { "name" : "xbox", "offset" : 2, "bit" : 2, "layout" : "Button" },
        { "name" : "leftTrigger", "offset" : 4, "format" : "BYTE" },
        { "name" : "rightTrigger", "offset" : 5, "format" : "BYTE" },
        { "name" : "leftStick", "offset" : 6, "format" : "VC2S" },
        { "name" : "leftStick/x", "offset" : 0, "format" : "SHRT", "parameters" : "normalize,normalizeMin=-0.5,normalizeMax=0.5" },
        { "name" : "leftStick/y", "offset" : 2, "format" : "SHRT", "parameters" : "invert,normalize,normalizeMin=-0.5,normalizeMax=0.5" },
        { "name" : "rightStick", "offset" : 10, "format" : "VC2S" },
        { "name" : "rightStick/x", "offset" : 0, "format" : "SHRT", "parameters" : "normalize,normalizeMin=-0.5,normalizeMax=0.5" },
        { "name" : "rightStick/y", "offset" : 2, "format" : "SHRT", "parameters" : "invert,normalize,normalizeMin=-0.5,normalizeMax=0.5" }
    ]
}

The same principle applies if some buttons on your Device are swapped, for example. In this case, you can remap their offsets.
