Youve done some pretty powerful stuff in this chapter, conquering the basics of forward kinematics. Note that the methods I gave you here are probably not the only solutions to the subject. Theyre obviously tailored toward a particular application of the technology: making something walk. Feel free to leave things out, change things, or add whatever you want to this system. Experiment and see what you can come up with.
As a bonus, Ive provided another file, ch13_10.fla , in which youll see a much fuller application of forward kinematics, building on what youve done here. Check out that code for a few extra tips and tricks.
Next up, youll look at the other side of the coin: inverse kinematics.
