Designing Games with Game Maker - YoYo Games

You can change the way the mouse cursor looks like. You can choose any sprite for this. To
this end you can use the following variable:
cursor_sprite Indicates the sprite that is used to represent the cursor
(default no sprite is used, represented by a value of -1). You can assign one of
the sprites to this variable to have it been drawn automatically at the position
of the mouse cursor. (You can also switch off the windows mouse cursor in the
Global Game Settings.)
The joystick
There are some events associated with joysticks. But to have full control over the joysticks
there is a whole set of functions to deal with joysticks. Game Maker supports up to two
joysticks. So all of these functions take a joystick id as argument.
joystick_exists(id) Returns whether joystick id (1 or 2) exists.
joystick_name(id) Returns the name of the joystick
joystick_axes(id) Returns the number of axes of the joystick.
joystick_buttons(id) Returns the number of buttons of the joystick.
joystick_has_pov(id) Returns whether the joystick has point-of-view
capabilities.
joystick_direction(id) Returns the keycode (vk_numpad1 to
vk_numpad9) corresponding to the direction of joystick id (1 or 2).
joystick_check_button(id,numb) Returns whether the joystick button is
pressed (numb in the range 1-32).
joystick_xpos(id) Returns the position (-1 to 1) of the x-axis of joystick
id.
joystick_ypos(id) Returns the joysticks y-position.
joystick_zpos(id) Returns the joysticks z-position (if it has a z-axis).
joystick_rpos(id) Returns the joysticks rudder position (or fourth axis).
joystick_upos(id) Returns the joysticks u-position (or fifth axis).
joystick_vpos(id) Returns the joysticks v-position (or sixth axis).
joystick_pov(id) Returns the joysticks point-of view position. This is an
angle between 0 and 360 degrees. 0 is forwards, 90 to the right, 180
backwards and 270 to the left. When no point-of-view direction is pressed by
the user -1 is returned.
