###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!) # SDL_HINT_GAMECONTROLLER_SENSOR_FUSION A variable that controls whether the device's built-in accelerometer and gyro should be used as sensors for gamepads. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_hints.h) ## Syntax ```c #define SDL_HINT_GAMECONTROLLER_SENSOR_FUSION "SDL_GAMECONTROLLER_SENSOR_FUSION" ``` ## Remarks The variable can be set to the following values: - "0": Sensor fusion is disabled - "1": Sensor fusion is enabled for all controllers that lack sensors Or the variable can be a comma separated list of USB VID/PID pairs in hexadecimal form, e.g. 0xAAAA/0xBBBB,0xCCCC/0xDDDD The variable can also take the form of "@file", in which case the named file will be loaded and interpreted as the value of the variable. This hint should be set before a gamepad is opened. ## Version This hint is available since SDL 3.0.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryHints](CategoryHints)
