isJoystickConnected Source

Arguments

:: Int	Index of the joystick to check
-> IO Bool

Check if a joystick is connected.

getButtonCount Source

Arguments

:: Int	Index of the joystick
-> IO Int

Return the number of buttons supported by a joystick.

If the joystick is not connected, this function returns 0.

hasAxis Source

Arguments

:: Int	Index of the joystick
-> Int	Axis to check
-> IO Bool

Check if a joystick supports a given axis.

If the joystick is not connected, this function returns False.

isJoystickButtonPressed Source

Arguments

:: Int	Index of the joystick
-> Int	Button to check
-> IO Bool

Check if a joystick button is pressed.

If the joystick is not connected, this function returns False.

getAxisPosition Source

Arguments

:: Int	Index of the joystick
-> Int	Axis to check
-> IO Float

Get the current position of a joystick axis.

If the joystick is not connected, this function returns 0.

getJoystickIdentification Source

Arguments

:: Int	Index of the joystick
-> IO JoystickIdentification

Get the joystick information.

The result of this function will only remain valid until the next time the function is called.

updateJoystick :: IO () Source

Update the states of all joysticks.

This function is used internally by SFML, so you normally don't have to call it explicitely. However, you may need to call it if you have no window yet (or no window at all): in this case the joysticks states are not updated automatically.
