But it's found that after say (-90,0,0) the very next orientation is (-89, -180, -180) but I am expecting (-91, 0, 0).<br> When I used actor.getOrientationWXYZ() to get orientation, say after (-50, 0, 0) if we continuously rotate the actor to right both the X and Y axes are getting their value changed. Is there any <span style='color:#1F497D'>solution </span>to fix this problem.
