In order to use the asset, see the example, or read the instruction below:
In the Create event you must call the joystick_init() script. This checks the joystick(s) and list all of the buttons.
In the step event you must call the joystick_listen() script. This "listens" if the given joystick ID's button is pressed.
After you can use joystick_check_pressed()/_hold()/released() to get if the given joystick button is pressed/holding/released;
This fills the gap if joystick functions, if you have a joystick/gamepad, what can"t be recognized by gamepad_ event.
