NAME

SDL2::joystick - SDL Joystick Event Handling

SYNOPSIS

    use SDL2 qw[:joystick];

DESCRIPTION

The term "device_index" identifies currently plugged in joystick devices between 0 and SDL_NumJoysticks( ), with the exact joystick behind a device_index changing as joysticks are plugged and unplugged.

The term "instance_id" is the current instantiation of a joystick device in the system, if the joystick is removed and then re-inserted then it will get a new instance_id, instance_id's are monotonically increasing identifiers of a joystick plugged in.

The term "player_index" is the number assigned to a player on a specific controller. For XInput controllers this returns the XInput user index. Many joysticks will not be able to supply this information.

The term JoystickGUID is a stable 128-bit identifier for a joystick device that does not change over time, it identifies class of the device (a X360 wired controller for example). This identifier is platform dependent.

Functions

These functions may be imported with the :joystick tag or by name.

`SDL_LockJoysticks( )`

Locking for multi-threaded access to the joystick API.

If you are using the joystick API or handling events from multiple threads you should use these locking functions to protect access to the joysticks.

In particular, you are guaranteed that the joystick list won't change, so the API functions that take a joystick index will be valid, and joystick and game controller events will not be delivered.

`SDL_UnlockJoysticks( )`

Unlocking for multi-threaded access to the joystick API

If you are using the joystick API or handling events from multiple threads you should use these locking functions to protect access to the joysticks.

In particular, you are guaranteed that the joystick list won't change, so the API functions that take a joystick index will be valid, and joystick and game controller events will not be delivered.

`SDL_NumJoysticks( )`

Count the number of joysticks attached to the system.

        my $count = SDL_NumJoysticks( );

Returns the number of attached joysticks on success or a negative error code on failure; call SDL_GetError( ) for more information.

Most joysticks do not have trackballs.

Expected parameters include:

`SDL_JoystickUpdate( )`

Update the current state of the open joysticks.

This is called automatically by the event loop if any joystick events are enabled.

`SDL_JoystickEventState( ... )`

Enable/disable joystick event polling.

If joystick events are disabled, you must call SDL_JoystickUpdate( ) yourself and manually check the state of the joystick when you want joystick information.

It is recommended that you leave joystick event handling enabled.

WARNING: Calling this function may delete all events currently in SDL's event queue.

Expected parameters include:

state - can be one of SDL_QUERY, SDL_IGNORE, or SDL_ENABLE

Returns 1 if enabled, 0 if disabled, or a negative error code on failure; call SDL_GetError( ) for more information.

If state is SDL_QUERY then the current state is returned, otherwise the new processing state is returned.

`SDL_JoystickGetAxis( ... )`

Get the current state of an axis control on a joystick.

SDL makes no promises about what part of the joystick any given axis refers to. Your game should have some sort of configuration UI to let users specify what each axis should be bound to. Alternately, SDL's higher-level Game Controller API makes a great effort to apply order to this lower-level interface, so you know that a specific axis is the "left thumb stick," etc.

The value returned by SDL_JoystickGetAxis( ... ) is a signed integer (-32768 to 32767) representing the current position of the axis. It may be necessary to impose certain tolerances on these values to account for jitter.

Expected parameters include:

joystick - an SDL2::Joystick structure containing joystick information
axis - the axis to query; the axis indices start at index 0

Returns a 16-bit signed integer representing the current position of the axis or 0 on failure; call SDL_GetError( ) for more information.

`SDL_JoystickGetAxisInitialState( ... )`

Get the initial state of an axis control on a joystick.

The state is a value ranging from -32768 to 32767.

The axis indices start at index 0.

Expected parameters include:

joystick - an SDL2::Joystick structure containing joystick information
axis - the axis to query; the axis indices start at index 0
state - upon return, the initial value is supplied here

Return SDL_TRUE if this axis has any initial value, or SDL_FALSE if not.

`SDL_JoystickGetHat`

Get the current state of a POV hat on a joystick.

The returned value will be one of the following positions:

SDL_HAT_CENTERED
SDL_HAT_UP
SDL_HAT_RIGHT
SDL_HAT_DOWN
SDL_HAT_LEFT
SDL_HAT_RIGHTUP
SDL_HAT_RIGHTDOWN
SDL_HAT_LEFTUP
SDL_HAT_LEFTDOWN

Expected parameters include:

joystick - an SDL2::Joystick structure containing joystick information
hat - the hat index to get the state from; indices start at index 0

Returns the current hat position.

`SDL_JoystickGetBall( ... )`

Get the ball axis change since the last poll.

Trackballs can only return relative motion since the last call to SDL_JoystickGetBall( ... ), these motion deltas are placed into dx and dy.

Most joysticks do not have trackballs.

Expected parameters include:

joystick - the SDL2::Joystick to query
ball - the ball index to query; ball indices start at index 0
dx - stores the difference in the x axis position since the last poll
dy - stores the difference in the y axis position since the last poll

Returns 0 on success or a negative error code on failure; call SDL_GetError( ) for more information.

`SDL_JoystickGetButton( ... )`

Get the current state of a button on a joystick.

Expected parameters include:

joystick - an SDL2::Joystick structure containing joystick information
button - the button index to get the state from; indices start at index 0

Returns 1 if the specified button is pressed, 0 otherwise.

`SDL_JoystickRumble( ... )`

Start a rumble effect.

Each call to this function cancels any previous rumble effect, and calling it with 0 intensity stops any rumbling.

Expected parameters include:

joystick - the joystick to vibrate
low_frequency_rumble - the intensity of the low frequency (left) rumble motor, from 0 to 0xFFFF
high_frequency_rumble - the intensity of the high frequency (right) rumble motor, from 0 to 0xFFFF
duration_ms - the duration of the rumble effect, in milliseconds

Returns 0, or -1 if rumble isn't supported on this joystick.

`SDL_JoystickRumbleTriggers( ... )`

Start a rumble effect in the joystick's triggers

Each call to this function cancels any previous trigger rumble effect, and calling it with 0 intensity stops any rumbling.

Note that this function is for _trigger_ rumble; the first joystick to support this was the PlayStation 5's DualShock 5 controller. If you want the (more common) whole-controller rumble, use SDL_JoystickRumble() instead.

Expected parameters include:

joystick - the joystick to vibrate
left_rumble - the intensity of the left trigger rumble motor, from 0 to 0xFFFF
right_rumble - the intensity of the right trigger rumble motor, from 0 to 0xFFFF
duration_ms - the duration of the rumble effect, in milliseconds

Returns 0, or -1 if trigger rumble isn't supported on this joystick.

An example of a joystick LED is the light on the back of a PlayStation 4's DualShock 4 controller.

Expected parameters include:

joystick - the joystick to query

Return SDL_TRUE if the joystick has a modifiable LED, SDL_FALSE otherwise.

`SDL_JoystickSetLED( ... )`

Update a joystick's LED color.

An example of a joystick LED is the light on the back of a PlayStation 4's DualShock 4 controller.

Expected parameters include:

joystick - the joystick to update
