NAME

       SDL_SensorType - The different sensors defined by SDL.

SYNOPSIS

       #include <SDL3/SDL_sensor.h>

       typedef enum SDL_SensorType
       {
           SDL_SENSOR_INVALID = -1,    /**< Returned for an invalid sensor */
           SDL_SENSOR_UNKNOWN,         /**< Unknown sensor type */
           SDL_SENSOR_ACCEL,           /**< Accelerometer */
           SDL_SENSOR_GYRO,            /**< Gyroscope */
           SDL_SENSOR_ACCEL_L,         /**< Accelerometer for left Joy-Con controller and Wii nunchuk */
           SDL_SENSOR_GYRO_L,          /**< Gyroscope for left Joy-Con controller */
           SDL_SENSOR_ACCEL_R,         /**< Accelerometer for right Joy-Con controller */
           SDL_SENSOR_GYRO_R,          /**< Gyroscope for right Joy-Con controller */
           SDL_SENSOR_COUNT
       } SDL_SensorType;

DESCRIPTION

       Additional sensors may be available, using platform dependent semantics.

       Here are the additional Android sensors:

       Accelerometer sensor notes:

       The  accelerometer  returns  the  current  acceleration in SI meters per second squared. This measurement
       includes the force of gravity, so a device at rest will have an value of SDL_STANDARD_GRAVITY  away  from
       the center of the earth, which is a positive Y value.

       • values[0]: Acceleration on the x axis

       • values[1]: Acceleration on the y axis

       • values[2]: Acceleration on the z axis

       For  phones  and  tablets held in natural orientation and game controllers held in front of you, the axes
       are defined as follows:

       • -X ... +X : left ... right

       • -Y ... +Y : bottom ... top

       • -Z ... +Z : farther ... closer

       The accelerometer axis data is not changed when the device is rotated.

       Gyroscope sensor notes:

       The gyroscope returns the current rate of rotation in radians per second. The rotation is positive in the
       counter-clockwise direction. That is, an observer looking from a positive location on  one  of  the  axes
       would see positive rotation on that axis when it appeared to be rotating counter-clockwise.

       • values[0]: Angular speed around the x axis (pitch)

       • values[1]: Angular speed around the y axis (yaw)

       • values[2]: Angular speed around the z axis (roll)

       For  phones  and  tablets held in natural orientation and game controllers held in front of you, the axes
       are defined as follows:

       • -X ... +X : left ... right

       • -Y ... +Y : bottom ... top

       • -Z ... +Z : farther ... closer

       The gyroscope axis data is not changed when the device is rotated.

AVAILABILITY

       This enum is available since SDL 3.2.0.
