Documentation

countAvailable :: IO Int Source

Counts the number of joysticks attached to the system.

tryName :: JoystickIndex -> IO (Maybe String) Source

Gets joystick name. Returns Nothing on error.

name :: JoystickIndex -> IO String Source

Gets joystick name. Throws an exception on error.

tryOpen :: JoystickIndex -> IO (Maybe Joystick) Source

Opens a joystick for use. Returns Nothing on error.

open :: JoystickIndex -> IO Joystick Source

Opens a joystick for use. Throws an exception on error.

opened :: JoystickIndex -> IO Bool Source

Determines if a joystick has been opened.

index :: Joystick -> JoystickIndex Source

Gets the index of an Joystick.

axesAvailable :: Joystick -> Int Source

Gets the number of joystick axes.

ballsAvailable :: Joystick -> Int Source

Gets the number of joystick trackballs.

hatsAvailable :: Joystick -> Int Source

Gets the number of joystick hats.

buttonsAvailable :: Joystick -> Int Source

Gets the number of joystick buttons.

update :: IO () Source

Updates the state of all joysticks.

getAxis :: Joystick -> Word8 -> IO Int16 Source

Gets the current state of an axis.

getHat :: Joystick -> Word8 -> IO [Hat] Source

Gets the current state of a joystick hat.

getButton :: Joystick -> Word8 -> IO Bool Source

Gets the current state of a given button on a given joystick.

getBall :: Joystick -> Word8 -> IO (Maybe (Int16, Int16)) Source

Gets relative trackball motion.

close :: Joystick -> IO () Source

Force finalization of a previous opened Joystick. Only supported with GHC.
