It works perfectly except for the fact that regardless of the orientation of the sprite object, the angle is still the same. right = Vector3.Note: The angle returned will always be between -180 and 180 degrees, because the method returns the smallest angle between the vectors. Note: The angle returned will always be between -180 and 180 degrees, because the method returns the smallest angle between the vectors. But I wanted to know how to get the angle between two vectors using atan2. The angle between CA and CB is the value Quaternion. Also vectors have direction!
