SDL_SensorEvent

Sensor event structure (event.sensor.*)

Header File

Defined in [SDL_events.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_events.h), but apps should _only_ `#include "SDL.h"`!

Syntax

typedef struct SDL_SensorEvent
{
    Uint32 type;        /**< ::SDL_SENSORUPDATE */
    Uint32 timestamp;   /**< In milliseconds, populated using SDL_GetTicks() */
    Sint32 which;       /**< The instance ID of the sensor */
    float data[6];      /**< Up to 6 values from the sensor - additional values can be queried using SDL_SensorGetData() */
    Uint64 timestamp_us; /**< The timestamp of the sensor reading in microseconds, if the hardware provides this information. */
} SDL_SensorEvent;

Data Fields

Uint32	type	SDL_SENSORUPDATE
Uint32	timestamp	In milliseconds, populated using SDL_GetTicks()
Sint32	which	The instance ID of the sensor
float[6]	data	Up to 6 values from the sensor - additional values can be queried using SDL_SensorGetData()
