Sensor

Enums

enum sfSensorType

Sensor Types.

Values:

enumerator sfSensorAccelerometer

Measures the raw acceleration (m/s^2)

enumerator sfSensorGyroscope

Measures the raw rotation rates (degrees/s)

enumerator sfSensorMagnetometer

Measures the ambient magnetic field (micro-teslas)

enumerator sfSensorGravity

Measures the direction and intensity of gravity, independent of device acceleration (m/s^2)

enumerator sfSensorUserAcceleration

Measures the direction and intensity of device acceleration, independent of the gravity (m/s^2)

enumerator sfSensorOrientation

Measures the absolute 3D orientation (degrees)

Values:

enumerator sfSensorCount

The total number of sensor types.

Functions

bool sfSensor_isAvailable(sfSensorType sensor)

Check if a sensor is available on the underlying platform.

Parameters:

• sensor – Sensor to check

Returns:

true if the sensor is available, false otherwise

void sfSensor_setEnabled(sfSensorType sensor, bool enabled)

Enable or disable a sensor.

All sensors are disabled by default, to avoid consuming too much battery power. Once a sensor is enabled, it starts sending events of the corresponding type.

This function does nothing if the sensor is unavailable.

Parameters:

• sensor – Sensor to enable

• enabled – true to enable, false to disable

sfVector3f sfSensor_getValue(sfSensorType sensor)

Get the current sensor value.

Parameters:

• sensor – Sensor to read

Returns:

The current sensor value
