NAME¶

SDL_AddGamepadMapping - Add support for gamepads that SDL is unaware of or change the binding of an existing gamepad.

SYNOPSIS¶

#include "SDL3/SDL.h"

int SDL_AddGamepadMapping(const char *mapping);

DESCRIPTION¶

The mapping string has the format "GUID,name,mapping", where GUID is the string value from SDL_GetJoystickGUIDString (), name is the human readable string for the device and mappings are gamepad mappings to joystick ones. Under Windows there is a reserved GUID of "xinput" that covers all 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 gamepad axes and vice versa.

This string shows an example of a valid mapping for a gamepad:
