Chapter 5 Using Behaviors 397
By default, the anchor point is located at the center of each object. Prior to adding
behaviors to animate these objects, you need to move the anchor points so that the
objects move the way they’re supposed to. In this example, the hands should spin
about the center of the clock face, not the center of the hand itself, and the pendulum
should swing from its top.
2 Choose the Adjust Anchor Point tool, and move the anchor points of both hand objects
and the pendulum object to the area that should appear to be attached to the rest of
the clock.
3 Now that the composition is set up to be animated, the only remaining thing to do is
to assign behaviors to each of the objects. Select the minute hand object, and open
the Properties tab in the Inspector. Control-click the Rotation parameter, then choose
Rate from the shortcut menu to apply the Rate parameter behavior.
