Questions about IK-bones

programming flash
1
  1. Is it possible to mix shapes and movieclips in a IK-skeleton? In other words, connect shapes and movieclips?
  2. When bending a shape with a couple of bones too much, the shape will become transparent at places it overlaps itself. Is there any way to prevent this? I want to create bodies that bend in all sorts of ways but I don’t want to see through the shape at places where it overlaps itself.
  3. It will not look very realistic if all body parts just can rotates 360 degrees around the z-axis. They should be able to scale down to create a 3D-illusion.
    Is it possible to resize the length of a bone and at the same time make the movieclip to also shrink in one axis?
  4. Look at the file. Is there any way to prevent the body from being stretched out when he lifts the arms?

Please help!
