pygame.joystick
- Pygame module for interacting with joysticks, gamepads, and trackballs.— Initialize the joystick module. — Uninitialize the joystick module. — Returns True if the joystick module is initialized. — Returns the number of joysticks. — Create a new Joystick object. The joystick module manages the joystick devices on a computer. Joystick devices include trackballs and video-game-style gamepads, and the module allows the use of multiple buttons and "hats". Computers may manage multiple joysticks at a time. Each instance of the Joystick class represents one gaming device plugged into the computer. If a gaming pad has multiple joysticks on it, then the joystick object can actually represent multiple joysticks on that single game device. For a quick way to initialise the joystick module and get a list of Joystick instances use the following code: pygame.joystick.init() joysticks = [pygame.joystick.Joystick(x) for x in range(pygame.joystick.get_count())] The following event types will be generated by the joysticks JOYAXISMOTION JOYBALLMOTION JOYBUTTONDOWN JOYBUTTONUP JOYHATMOTION And in pygame 2, which supports hotplugging: JOYDEVICEADDED JOYDEVICEREMOVED Note that in pygame 2, joysticks events use a unique "instance ID". The device index passed in the constructor to a Joystick object is not unique after devices have been added and removed. You must call Joystick.get_instance_id()to find the instance ID that was assigned to a Joystick on opening.The event queue needs to be pumped frequently for some of the methods to work. So call one of pygame.event.get, pygame.event.wait, or pygame.event.pump regularly. To be able to get joystick events and update the joystick objects while the window is not in focus, you may set the SDL_JOYSTICK_ALLOW_BACKGROUND_EVENTSenvironment variable. See environment variables for more details.- pygame.joystick.init()¶
- Initialize the joystick module.init() -> NoneThis function is called automatically by pygame.init().It initializes the joystick module. The module must be initialized before any other functions will work. It is safe to call this function more than once. 
 - pygame.joystick.quit()¶
- Uninitialize the joystick module.quit() -> NoneUninitialize the joystick module. After you call this any existing joystick objects will no longer work. It is safe to call this function more than once. 
 - pygame.joystick.get_init()¶
- Returns True if the joystick module is initialized.get_init() -> boolTest if the pygame.joystick.init()function has been called.
 - pygame.joystick.get_count()¶
- Returns the number of joysticks.get_count() -> countReturn the number of joystick devices on the system. The count will be 0if there are no joysticks on the system.When you create Joystick objects using Joystick(id), you pass an integer that must be lower than this count.
 - pygame.joystick.Joystick¶
- Create a new Joystick object.Joystick(id) -> Joystick— initialize the Joystick — uninitialize the Joystick — check if the Joystick is initialized — get the device index (deprecated) — get the joystick instance id — get the joystick GUID — get the approximate power status of the device — get the Joystick system name — get the number of axes on a Joystick — get the current position of an axis — get the number of trackballs on a Joystick — get the relative position of a trackball — get the number of buttons on a Joystick — get the current button state — get the number of hat controls on a Joystick — get the position of a joystick hat — Start a rumbling effect — Stop any rumble effect playing Create a new joystick to access a physical device. The id argument must be a value from 0topygame.joystick.get_count() - 1.Joysticks are initialised on creation and are shut down when deallocated. Once the device is initialized the pygame event queue will start receiving events about its input. Changed in pygame 2.0.0: Joystick objects are now opened immediately on creation. - init()¶
- initialize the Joystickinit() -> NoneInitialize the joystick, if it has been closed. It is safe to call this even if the joystick is already initialized. Deprecated since pygame 2.0.0: In future it will not be possible to reinitialise a closed Joystick object. Will be removed in Pygame 2.1. 
 - quit()¶
- uninitialize the Joystickquit() -> NoneClose a Joystick object. After this the pygame event queue will no longer receive events from the device. It is safe to call this more than once. 
 - get_init()¶
- check if the Joystick is initializedget_init() -> boolReturn True if the Joystick object is currently initialised. 
 - get_id()¶
- get the device index (deprecated)get_id() -> intReturns the original device index for this device. This is the same value that was passed to the Joystick()constructor. This method can safely be called while the Joystick is not initialized.Deprecated since pygame 2.0.0: The original device index is not useful in pygame 2. Use get_instance_id()instead. Will be removed in Pygame 2.1.
 - get_instance_id() int¶
- get the joystick instance idget_instance_id() -> intGet the joystick instance ID. This matches the instance_idfield that is given in joystick events.New in pygame 2.0.0dev11. 
 - get_guid() str¶
- get the joystick GUIDget_guid() -> strGet the GUID string. This identifies the exact hardware of the joystick device. New in pygame 2.0.0dev11. 
 - get_power_level() str¶
- get the approximate power status of the deviceget_power_level() -> strGet a string giving the power status of the device. One of: empty,low,medium,full,wired,max, orunknown.New in pygame 2.0.0dev11. 
 - get_name()¶
- get the Joystick system nameget_name() -> stringReturns the system name for this joystick device. It is unknown what name the system will give to the Joystick, but it should be a unique name that identifies the device. This method can safely be called while the Joystick is not initialized. 
 - get_numaxes()¶
- get the number of axes on a Joystickget_numaxes() -> intReturns the number of input axes are on a Joystick. There will usually be two for the position. Controls like rudders and throttles are treated as additional axes. The pygame.JOYAXISMOTIONevents will be in the range from-1.0to1.0. A value of0.0means the axis is centered. Gamepad devices will usually be-1,0, or1with no values in between. Older analog joystick axes will not always use the full-1to1range, and the centered value will be some area around0.Analog joysticks usually have a bit of noise in their axis, which will generate a lot of rapid small motion events. 
 - get_axis()¶
- get the current position of an axisget_axis(axis_number) -> floatReturns the current position of a joystick axis. The value will range from -1to1with a value of0being centered. You may want to take into account some tolerance to handle jitter, and joystick drift may keep the joystick from centering at0or using the full range of position values.The axis number must be an integer from 0toget_numaxes() - 1.When using gamepads both the control sticks and the analog triggers are usually reported as axes. 
 - get_numballs()¶
- get the number of trackballs on a Joystickget_numballs() -> intReturns the number of trackball devices on a Joystick. These devices work similar to a mouse but they have no absolute position; they only have relative amounts of movement. The pygame.JOYBALLMOTIONevent will be sent when the trackball is rolled. It will report the amount of movement on the trackball.
 - get_ball()¶
- get the relative position of a trackballget_ball(ball_number) -> x, yReturns the relative movement of a joystick button. The value is a x, ypair holding the relative movement since the last call to get_ball.The ball number must be an integer from 0toget_numballs() - 1.
 - get_numbuttons()¶
- get the number of buttons on a Joystickget_numbuttons() -> intReturns the number of pushable buttons on the joystick. These buttons have a boolean (on or off) state. Buttons generate a pygame.JOYBUTTONDOWNandpygame.JOYBUTTONUPevent when they are pressed and released.
 - get_button()¶
- get the current button stateget_button(button) -> boolReturns the current state of a joystick button. 
 - get_numhats()¶
- get the number of hat controls on a Joystickget_numhats() -> intReturns the number of joystick hats on a Joystick. Hat devices are like miniature digital joysticks on a joystick. Each hat has two axes of input. The pygame.JOYHATMOTIONevent is generated when the hat changes position. Thepositionattribute for the event contains a pair of values that are either-1,0, or1. A position of(0, 0)means the hat is centered.
 - get_hat()¶
- get the position of a joystick hatget_hat(hat_number) -> x, yReturns the current position of a position hat. The position is given as two values representing the xandyposition for the hat.(0, 0)means centered. A value of-1means left/down and a value of1means right/up: so(-1, 0)means left;(1, 0)means right;(0, 1)means up;(1, 1)means upper-right; etc.This value is digital, i.e., each coordinate can be-1,0or1but never in-between.The hat number must be between 0andget_numhats() - 1.
 - rumble()¶
- Start a rumbling effectrumble(low_frequency, high_frequency, duration) -> boolStart a rumble effect on the joystick, with the specified strength ranging from 0 to 1. Duration is length of the effect, in ms. Setting the duration to 0 will play the effect until another one overwrites it or Joystick.stop_rumble()is called. If an effect is already playing, then it will be overwritten.Returns True if the rumble was played successfully or False if the joystick does not support it or pygame.version.SDL()tupled integers of the SDL library version is below 2.0.9.New in pygame 2.0.2. 
 - stop_rumble()¶
- Stop any rumble effect playingstop_rumble() -> NoneStops any rumble effect playing on the joystick. See Joystick.rumble()for more information.New in pygame 2.0.2.
