Gamepad.axes

The Gamepad.axes property of the Gamepad interface returns an array representing the controls with axes present on the device (e.g. analog thumb sticks).-

Each entry in the array is a floating point value in the range -1.0 – 1.0, representing the axis position from the lowest value (-1.0) to the highest value (1.0).
