Ignore gyroscope yaw
Hi, I've added controls to my game using the gyroscope gravity. It works perfectly but the only position for the input to be null is when the phone is flat (and the gravity vector is straight down).
To make possible to play the game also in other orientations I added an initialRotation which rotates the gravity vector to offset the "null rotation".
The problem is that this solution works only when the phone is turned towards north, when the gyroscope attitude yaw is 0. If I turn around the offset rotation causes also a rotation around the Y axis of the gravity vector.
How should I obtain a quaternion attitude which ignores the yaw rotation?
I'm aware of the gyroscope quaternions being in a different coordinate system, that's why I apply the offset directly to the gravity vector.
Thanks a lot!
