How come when you animate movements in frame structure of an image using a tween, it goes all weired whilst animating. I had an image and as a test I decided to alter one of the points that make up the frame of the body I was affecting. By points, I mean the ones you see when you use the grey select tool. Instead of just seeing the movements take place in that one spot and then end how it should do, during the animation, lots of unrelated movements occur which make it look a complete mess and when the animation gets to the final key frame, it finishes off how it should look.
Why is the animation process not animating the way it should?
