Without getting into a lot more detail, try your hand at animating the catapult on
your own. Here are some items you can animate to make this a complete animation:
Spin the winch around as the arm releases, as if its rope is being yanked away from it.
•
•
Animate the entire catapult rocking forward and backward as the arm releases, simi-
lar to the way a car rocks when you jump onto the hood.
Move the catapult forward on a road, spinning its wheels as best you can to match
•
the distance it travels.
Design and build your own catapult, and animate it along the same lines.

Summary
In this chapter, you began to learn the fundamentals of animating a scene. Starting with
a bouncing ball, you learned how to work in the Graph Editor to set up and adjust timing
as well as how to add squash and stretch to the animation. The next exercise, throwing
an axe, showed you how to set up a scene for animation, expanded on your experience
