# 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 [<SDL3/SDL_hints.h>](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 3.1.3.
