This extension gives access to the sensors which can be found in most mobile devices.

The orientation sensor combines the gyroscope, accellerometer and compass in one sensor. This allows you to control game objects by slightly rotating the mobile device in your hands. You can access the location data via the “alpha”, “beta” and “gamma” values which are explained in the next section.

The “alpha” value corresponds to the axis which points to the sky when your phone is lying on a table with its display pointing upwards. You can easily create a compass using the “alpha” rotation value.

Range: 0 to 360 degrees

The “beta” axis runs through the narrow edge of the phone.

Range: -180 to 180 degrees

The “gamma” axis runs through the longer edge of the phone.

Range: -90 to 90 degrees

Sensor Active

This condition checks wether the sensor has been activated before and is delivering location data.

Orientation Alpha

This condition lets you compare the value of alpha to a number or variable.

Orientation Beta

This condition lets you compare the value of beta to a number or variable.

Orientation Gamma

This condition lets you compare the value of gamma to a number or variable.
