Chapter 9 Behaviors 305
Duplicate a behavior
You can also duplicate a behavior in place.
1 Select the behavior to duplicate.
2 Do one of the following:
•
Choose Edit > Duplicate (or press Command-D).
•
Control-click the behavior to duplicate, then choose Duplicate from the shortcut menu.
Drag a duplicate of a behavior to another object
You can also duplicate a behavior and apply the duplicate to another object in the Layers list
or Timeline.
m Option-drag a behavior to another object to apply the duplicated behavior.
The duplicated behavior is applied to the second object, and the original behavior is left in its
original location.
Reorder behaviors
1 Drag the behavior up or down in the list of nested behaviors applied to the same object.
A position indicator appears.
Position indicator
shows where you are
moving the behavior.
2 When the position indicator is in the correct row, release the mouse button.
All behaviors combine according to a predetermined order of operations (see Behavior order
of operations on page 306) regardless of their order in the Layers list. Therefore, reordering the
behaviors has no effect on the resulting animations, with a few exceptions:
•
The Stop behavior suspends the activity of all behaviors beneath it that affect the same
parameter. The Stop behavior has no effect on behaviors above it in the Layers list.
•
Parameter behaviors are applied in the order that they are added, from the bottom to the top
in the Layers list, so you need to think about how you are building the operation. For example,
imagine a circle shape with an X Position of 50 in the Canvas. If you apply a Rate Parameter
behavior with a positive Rate value to the X Position of the circle, the circle will move to the
right from its starting X Position of 50. If you then apply a Negate Parameter behavior to the
circle’s X Position, the circle will start at –50 in the Canvas and move to the left. The effect you
see in the Canvas is the result of each behavior acting upon the previously applied behavior:
an X Position value of 50 is modified by the Rate behavior (in a positive direction), which is in
turn modified by the Negate behavior, changing the X Position and rate to negative values.
If you swap the order of Rate and Negate in the Layers list, Negate is processed first. The circle’s
X Position value of 50 is turned into –50. This is then passed as the input to Rate, which moves
the circle in a positive direction. Now the circle begins at the –50 X Position in the Canvas and
moves to the right.
