100 Tutorial 2 Basic Motion Behaviors
The further you drag the arrow around the circle, the faster the spin. You can “spin the
dial” multiple times as well. Use the above image as a guide to set the speed of the
spin for this tutorial.
To modify the Grow/Shrink behavior:
1 In the Layers tab, select the Grow/Shrink behavior.
2 In the Grow/Shrink Dashboard, click the edge of the box and drag inward very slightly
(so the Scale Rate in the Inspector is no less than -5).

The object spins and shrinks over time.
In the Grow/Shrink Dashboard, dragging inward shrinks the object over time, dragging
outward grows the object over time. To grow or shrink the object on a single axis, drag
the small white control points inward or outward.
Offsetting Behaviors
Earlier in this tutorial you stopped the effect of the Throw behavior by trimming it in
the Timeline. It was mentioned that there are cases where this may yield undesirable
effects. The Grow/Shrink behavior is a good example of one of those cases.
To offset the Grow/Shrink behavior:
1 Show the Timeline (click the Timing icon or press Command+7).
