"""Joystick, tablet and USB HID device support.
|
||
|
|
|
||
|
|
This module provides a unified interface to almost any input device, besides
|
||
|
|
the regular mouse and keyboard support provided by
|
||
|
|
:py:class:`~pyglet.window.Window`. At the lowest
|
||
|
|
level, :py:func:`get_devices` can be used to retrieve a list of all supported
|
||
|
|
devices, including joysticks, tablets, space controllers, wheels, pedals, remote
|
||
|
|
controls, keyboards and mice. The set of returned devices varies greatly
|
||
|
|
depending on the operating system (and, of course, what's plugged in).
|
||
|
|
|
||
|
|
At this level pyglet does not try to interpret *what* a particular device is,
|
||
|
|
merely what controls it provides. A :py:class:`Control` can be either a button,
|
||
|
|
whose value is either ``True`` or ``False``, or a relative or absolute-valued
|
||
|
|
axis, whose value is a float. Sometimes the name of a control can be provided
|
||
|
|
(for example, ``x``, representing the horizontal axis of a joystick), but often
|
||
|
|
not. In these cases the device API may still be useful -- the user will have
|
||
|
|
to be asked to press each button in turn or move each axis separately to
|
||
|
|
identify them.
|
||
|
|
|
||
|
|
Higher-level interfaces are provided for joysticks, tablets and the Apple
|
||
|
|
remote control. These devices can usually be identified by pyglet positively,
|
||
|
|
and a base level of functionality for each one provided through a common
|
||
|
|
interface.
|
||
|
|
|
||
|
|
To use an input device:
|
||
|
|
|
||
|
|
1. Call :py:func:`get_devices`, :py:func:`get_apple_remote` or
|
||
|
|
:py:func:`get_joysticks`
|
||
|
|
to retrieve and identify the device.
|
||
|
|
2. For low-level devices (retrieved by :py:func:`get_devices`), query the
|
||
|
|
devices list of controls and determine which ones you are interested in. For
|
||
|
|
high-level interfaces the set of controls is provided by the interface.
|
||
|
|
3. Optionally attach event handlers to controls on the device.
|
||
|
|
4. Call :py:meth:`Device.open` to begin receiving events on the device. You can
|
||
|
|
begin querying the control values after this time; they will be updated
|
||
|
|
asynchronously.
|
||
|
|
5. Call :py:meth:`Device.close` when you are finished with the device (not
|
||
|
|
needed if your application quits at this time).
|
||
|
|
|
||
|
|
To use a tablet, follow the procedure above using :py:func:`get_tablets`, but
|
||
|
|
note that no control list is available; instead, calling :py:meth:`Tablet.open`
|
||
|
|
returns a :py:class:`TabletCanvas` onto which you should set your event
|
||
|
|
handlers.
