Include file for SDL game controller event handling
In order to use these functions, SDL_Init() must have been called with the ::SDL_INIT_GAMECONTROLLER flag. This causes SDL to scan the system for game controllers, and load appropriate drivers.
If you would like to receive controller updates while the application is in the background, you should set the following hint before calling SDL_Init(): SDL_HINT_JOYSTICK_ALLOW_BACKGROUND_EVENTS

The list of axes available from a controller
Thumbstick axis values range from SDL_JOYSTICK_AXIS_MIN to SDL_JOYSTICK_AXIS_MAX, and are centered within ~8000 of zero, though advanced UI will allow users to set or autodetect the dead zone, which varies between controllers.
Trigger axis values range from 0 to SDL_JOYSTICK_AXIS_MAX.

DECLSPEC int SDLCALL SDL_GameControllerAddMappingsFromRW | ( | SDL_RWops * | rw, |
int | freerw | ||
) |
To count the number of game controllers in the system for the following: int nJoysticks = SDL_NumJoysticks(); int nGameControllers = 0; for (int i = 0; i < nJoysticks; i++) { if (SDL_IsGameController(i)) { nGameControllers++; } }
Using the SDL_HINT_GAMECONTROLLERCONFIG hint or the SDL_GameControllerAddMapping() you can add support for controllers SDL is unaware of or cause an existing controller to have a different binding. The format is: guid,name,mappings
Where GUID is the string value from SDL_JoystickGetGUIDString(), name is the human readable string for the device and mappings are controller mappings to joystick ones. Under Windows there is a reserved GUID of "xinput" that covers any XInput devices. The mapping format for joystick is: bX - a joystick button, index X hX.Y - hat X with value Y aX - axis X of the joystick Buttons can be used as a controller axis and vice versa.
This string shows an example of a valid mapping for a controller "03000000341a00003608000000000000,PS3 Controller,a:b1,b:b2,y:b3,x:b0,start:b9,guide:b12,back:b8,dpup:h0.1,dpleft:h0.8,dpdown:h0.4,dpright:h0.2,leftshoulder:b4,rightshoulder:b5,leftstick:b10,rightstick:b11,leftx:a0,lefty:a1,rightx:a2,righty:a3,lefttrigger:b6,righttrigger:b7", Load a set of mappings from a seekable SDL data stream (memory or file), filtered by the current SDL_GetPlatform() A community sourced database of controllers is available at https://raw.github.com/gabomdq/SDL_GameControllerDB/master/gamecontrollerdb.txt
If freerw
is non-zero, the stream will be closed after being read.

Is the joystick on this index supported by the game controller interface?
const DECLSPEC char* SDLCALL SDL_GameControllerNameForIndex | ( | int | joystick_index | ) |
Get the implementation dependent name of a game controller. This can be called before any controllers are opened. If no name can be found, this function returns NULL.

Get the mapping of a game controller. This can be called before any controllers are opened.
DECLSPEC SDL_GameController* SDLCALL SDL_GameControllerOpen | ( | int | joystick_index | ) |
Open a game controller for use. The index passed as an argument refers to the N'th game controller on the system. This index is not the value which will identify this controller in future controller events. The joystick's instance id (SDL_JoystickID) will be used there instead.
DECLSPEC SDL_GameController* SDLCALL SDL_GameControllerFromInstanceID | ( | SDL_JoystickID | joyid | ) |
Return the SDL_GameController associated with an instance id.
DECLSPEC SDL_GameController* SDLCALL SDL_GameControllerFromPlayerIndex | ( | int | player_index | ) |
Return the SDL_GameController associated with a player index.
const DECLSPEC char* SDLCALL SDL_GameControllerName | ( | SDL_GameController * | gamecontroller | ) |
Return the name for this currently opened controller
