I followed Fabrice's tutorial. When I call the update method in the render loop and pass a value 0 the object, in my case a cube, is positioned at the beginning of the path. If I change the value passed to anything other than 0 but still below 1, the code breaks. Why is pathAnimator.update(0); working, but pathAnimator.update(0.5); not? Any answers will be appreciated. :) Thanks, Patrick
