## NAME

SDL\_HINT\_JOYSTICK\_HAPTIC\_AXES - A variable containing a list of devices and their desired number of haptic (force feedback) enabled axis.

## HEADER FILE

Defined in SDL3/SDL\_hints.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**#define SDL\_HINT\_JOYSTICK\_HAPTIC\_AXES** *SDL\_JOYSTICK\_HAPTIC\_AXES"*

## DESCRIPTION

The format of the string is a comma separated list of USB VID/PID pairs in hexadecimal form plus the number of desired axes, e.g. **0xAAAA/0xBBBB/1,0xCCCC/0xDDDD/3** This hint supports a "wildcard" device that will set the number of haptic axes on all initialized haptic devices which were not defined explicitly in this hint. **0xFFFF/0xFFFF/1** This hint should be set before a controller is opened. The number of haptic axes won't exceed the number of real axes found on the device.

## AVAILABILITY

This hint is available since SDL 3.2.5.
