sdlxSendJoystickVirtualSensorData function joystick

bool sdlxSendJoystickVirtualSensorData(Pointer<SdlJoystick> joystick, int type, int sensorTimestamp, List<double> data,)

Send a sensor update for an opened virtual joystick.

Please note that values set here will not be applied until the next call to SDL_UpdateJoysticks, which can either be called directly, or can be called indirectly through various other SDL APIs, including, but not limited to the following: SDL_PollEvent, SDL_PumpEvents, SDL_WaitEventTimeout, SDL_WaitEvent.

\param joystick the virtual joystick on which to set state. \param type the type of the sensor on the virtual joystick to update. \param sensor_timestamp a 64-bit timestamp in nanoseconds associated with the sensor reading. \param data the data associated with the sensor reading. \param num_values the number of values pointed to by data. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety It is safe to call this function from any thread.

\since This function is available since SDL 3.2.0.
