We are using the term project to describe advanced exercises that are more challenging than regular exercises. The projects in this chapter involve motion of human body parts. Professional animators spend many hours mastering the art of making these movements look realistic. Our focus is on mastering the art (and science) of writing methods in a program.
Your Own Creation (Open-ended)
Choose an animal or a person from one of the galleries. The object selected must have at least two legs, arms, and/or wings that can move, turn, and roll. Write three class level methods that substantially add functionality to what the objects of the class know how to do. Use Save Object to create a new class with a different name. Add an instance of your new class to a new world. Then write an animation program to demonstrate the new methods.
