///
|
|
/// sf::Joystick provides an interface to the state of the

|
/// joysticks. It only contains static functions, so it's not
|
|
/// meant to be instantiated. Instead, each joystick is identified
|
|
/// by an index that is passed to the functions of this class.
|
|
///
|
|
/// This class allows users to query the state of joysticks at any
|
|
/// time and directly, without having to deal with a window and
|
|
/// its events. Compared to the JoystickMoved, JoystickButtonPressed
|
|
/// and JoystickButtonReleased events, sf::Joystick can retrieve the
|
|
/// state of axes and buttons of joysticks at any time
|
|
/// (you don't need to store and update a boolean on your side
|
|
/// in order to know if a button is pressed or released), and you
|
|
/// always get the real state of joysticks, even if they are
|
|
/// moved, pressed or released when your window is out of focus
|
|
/// and no event is triggered.
|
|
///
|
|
/// SFML supports:
|
|
/// \li 8 joysticks (sf::Joystick::Count)
|
|
/// \li 32 buttons per joystick (sf::Joystick::ButtonCount)
|
|
/// \li 8 axes per joystick (sf::Joystick::AxisCount)
|
|
///
|
|
/// Unlike the keyboard or mouse, the state of joysticks is sometimes
|
|
/// not directly available (depending on the OS), therefore an update()
|
|
/// function must be called in order to update the current state of
|
|
/// joysticks. When you have a window with event handling, this is done
|
|
/// automatically, you don't need to call anything. But if you have no
|
|
/// window, or if you want to check joysticks state before creating one,
|
|
/// you must call sf::Joystick::update explicitly.
|
|
///
|
|
/// Usage example:
|
|
/// \code
|
|
/// // Is joystick #0 connected?
|
|
/// bool connected = sf::Joystick::isConnected(0);
|
|
///
|
|
/// // How many buttons does joystick #0 support?
|
|
/// unsigned int buttons = sf::Joystick::getButtonCount(0);
|
|
///
|
|
/// // Does joystick #0 define a X axis?
|
|
/// bool hasX = sf::Joystick::hasAxis(0, sf::Joystick::X);
|
|
///
|
|
/// // Is button #2 pressed on joystick #0?
|
|
/// bool pressed = sf::Joystick::isButtonPressed(0, 2);
|
|
///
|
|
/// // What's the current position of the Y axis on joystick #0?
|
|
/// float position = sf::Joystick::getAxisPosition(0, sf::Joystick::Y);
