"""High-level interface for joystick-like devices. This includes a wide range
of analog and digital joysticks, gamepads, controllers, and possibly even
steering wheels and other input devices. There is unfortunately no easy way to
distinguish between most of these different device types.
For a simplified subset of Joysticks, see the :py:class:`~pyglet.input.Controller`
interface. This covers a variety of popular game console controllers. Unlike
Joysticks, Controllers have strictly defined layouts and inputs.
To use a joystick, first call `open`, then in your game loop examine
the values of `x`, `y`, and so on. These values are normalized to the
range [-1.0, 1.0].
To receive events when the value of an axis changes, attach an
on_joyaxis_motion event handler to the joystick. The :py:class:`~pyglet.input.Joystick` instance,
axis name, and current value are passed as parameters to this event.
To handle button events, you should attach on_joybutton_press and
on_joy_button_release event handlers to the joystick. Both the :py:class:`~pyglet.input.Joystick`
instance and the index of the changed button are passed as parameters to
these events.
Alternately, you may attach event handlers to each individual button in
`button_controls` to receive on_press or on_release events.
To use the hat switch, attach an on_joyhat_motion event handler to the
joystick. The handler will be called with both the hat_x and hat_y values
whenever the value of the hat switch changes.
The device name can be queried to get the name of the joystick.
:Ivariables:
`device` : `Device`
The underlying device used by this joystick interface.
`x` : float
Current X (horizontal) value ranging from -1.0 (left) to 1.0
(right).
`y` : float
Current y (vertical) value ranging from -1.0 (top) to 1.0
(bottom).
`z` : float
Current Z value ranging from -1.0 to 1.0. On joysticks the Z
value is usually the throttle control. On controllers the Z
value is usually the secondary thumb vertical axis.
`rx` : float
Current rotational X value ranging from -1.0 to 1.0.
`ry` : float
Current rotational Y value ranging from -1.0 to 1.0.
`rz` : float
Current rotational Z value ranging from -1.0 to 1.0. On joysticks
the RZ value is usually the twist of the stick. On game
controllers the RZ value is usually the secondary thumb horizontal
axis.
`hat_x` : int
Current hat (POV) horizontal position; one of -1 (left), 0
(centered) or 1 (right).
`hat_y` : int
Current hat (POV) vertical position; one of -1 (bottom), 0
(centered) or 1 (top).
`buttons` : list of bool
List of boolean values representing current states of the buttons.
These are in order, so that button 1 has value at ``buttons[0]``,
and so on.
`x_control` : `AbsoluteAxis`
Underlying control for `x` value, or ``None`` if not available.
