SensorGetOrientation (Function)

In french: CapteurRécupèreOrientation

Retrieves the current orientation of the device on one of its 3 axes.

Example

nOrientation is int
nOrientation = SensorGetOrientation(snrAzimuth)
IF ErrorOccurred = True THEN
	Error(ErrorInfo())
	RETURN
END
Info(StringBuild("Orientation du téléphone par rapport au Nord : %1 degrés", nOrientation))

// Appareil en mode portrait ou paysage ?
IF Abs(SensorGetOrientation(snrRoll)) < 45 THEN
	// Appareil en mode portrait
ELSE
	// Appareil en mode paysage
END

// Appareil à plat ou à la verticale ?
IF Abs(SensorGetOrientation(snrPitch)) < 45 THEN
	// Appareil à plat
ELSE
	// Appareil à la verticale
END

Syntax

<Result> = SensorGetOrientation(<Orientation type>)

<Result>: Integer

Orientation of the device expressed in degrees according to the requested type of orientation.

<Orientation type>: Integer constant

Type of orientation to return:
snrAzimuth Orientation around the vertical axis (Z).
snrPitch Orientation around the horizontal axis (X).
snrRoll Orientation around the longitudinal axis (Y).

Remarks

Device orientation: definitions

The change of orientation can be specified according to the three following dimensions:

Azimuth Direction of object snapping with respect to magnetic North around vertical axis (Z). This direction is expressed in degrees (from 0 to 360 degrees). In this case, 0 or 360 corresponds to the North, 90 corresponds to the East, 180 corresponds to the South and 270 corresponds to the West.
Pitch Rotation of the device around the horizontal axis (X). This rotation is expressed in degrees (from -180 to 180). Its value is set to 0 degree when the device lies down flat with the screen pointing to the ceiling, -90 degrees when the device stands still with the top of the device pointing to the ceiling, 90 degrees when the device stands still with the top of the device pointing to the ground and -180/180 degrees when the device lies down flat with the screen pointing to the ground.
Roll Rotation of the device around the longitudinal axis (Y). This rotation is expressed in degrees (from -90 to 90). Its value is set to 0 degree when the device lies down flat with the screen pointing to the ceiling, -90 degrees when the screen is oriented to the left and 90 degrees when the screen is oriented to the right.

Coordinate system (assuming the device is laying flat, with the screen facing up):

The origin is found in the lower-left corner of the screen.
The X-axis represents the horizontal axis and it points to the right of the screen.
The Y-axis represents the longitudinal axis and it points to the top of the screen.
The Z-axis represents the vertical axis and it points outside the front of the screen.
