int SDL_GameControllerAddMappingsFromRW | ( | SDL_RWops * | rw, |

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
