Function glfwGetJoystickButtons

  • This function returns the state of all buttons of the specified joystick. Each element in the array is either GLFW_PRESS or GLFW_RELEASE.

    For backward compatibility with earlier versions that did not have glfwGetJoystickHats, the button array also includes all hats, each represented as four buttons. The hats are in the same order as returned by glfwGetJoystickHats and are in the order up, right, down and left. To disable these extra buttons, set the GLFW_JOYSTICK_HAT_BUTTONS init hint before initialization.

    If the specified joystick is not present this function will return NULL but will not generate an error. This can be used instead of first calling glfwJoystickPresent.

    Parameters

    • jid: number

      The joystick to query.

    • count: number

      Where to store the number of button states in the returned array. This is set to zero if the joystick is not present or an error occurred.

    Returns string

    An array of button states, or NULL if the joystick is not present or an error occurred.
