NAME

SDL_AttachVirtualJoystick - Attach a new virtual joystick.

SYNOPSIS

#include <SDL3/SDL_joystick.h>

SDL_JoystickID SDL_AttachVirtualJoystick(const SDL_VirtualJoystickDesc *desc);

DESCRIPTION

Apps can create virtual joysticks, that exist without hardware directly backing them, and have program-supplied inputs. Once attached, a virtual joystick looks like any other joystick that SDL can access. These can be used to make other things look like joysticks, or provide pre-recorded input, etc.

Once attached, the app can send joystick inputs to the new virtual joystick using SDL_SetJoystickVirtualAxis(), etc.

When no longer needed, the virtual joystick can be removed by calling SDL_DetachVirtualJoystick().

RETURN VALUE

Returns the joystick instance ID, or 0 on failure; call SDL_GetError() for more information.
