Please come see the Flash CS4 tutorials featuring animation with the MotionEditor, Inverse Kinematics (IK Bone tool) and work with the new 3D or x,y and z properties. The tutorials can be found at:
It is fun working with the IK Bone tool – I did a little spaceman for an in-class example. You can move the parts like a doll. It uses code to adjust the helmet with respect to the angle of motion of the body. You can use the figures to animate or you can let the user move the figures. In this second setting, you can also use code to move parts – that is very tricky and still being worked out a bit in this early version of the feature.
