Calibrate is a static class used to assist with comfortable mobile device accelerometer positions. Tilt based games are often more comfortable at 45 degrees than flat. It should be easy for users to hold their device at any angle though. They may want to lay down and then sit. Your game needs to be able to allow users to play as they please, calibrating the accelerometer offers this capability.
Simply drop the Calibrate static class into your project and call functions like so:
Calibrate.AccelerometerLandscape()
Calibrate.AccelerometerCurrentPitchLandscape()
Calibrate.AccelerometerCalibratedPitchLandscape()
Calibrate.AccelerometerPortrait()
Calibrate.AccelerometerCurrentPitchPortrait()
Calibrate.AccelerometerCalibratedPitchPortrait()
