380 Chapter 5 Using Behaviors
You can also set the Acceleration parameter to a negative value, effectively applying
“anti-gravity” to the object and making it fly up.
Dashboard control
The Dashboard lets you adjust the Acceleration parameter. When applied to a layer or
group (such as particles text, or a replicator), the Affect Objects checkbox also appears
in the Dashboard.
Parameters in the Inspector
Affect Objects: This parameter appears when this behavior is applied to an object that
contains multiple objects, such as a layer, particle emitter, replicator, or text object.
When this checkbox is turned on, all objects within the parent object are affected
individually. When this checkbox is turned off, all objects within the layer are affected
by the behavior together, as if they were a single object.
Acceleration: A slider defining the strength of gravity affecting the target object. The
higher this value, the faster the target object falls.

Orbit Around
Similar to the Attracted To behavior, the Orbit Around behavior’s default parameter
settings give the object sufficient initial velocity to orbit around another object in a
perfect circle.
Note: Behaviors such as Attractor and Repel applied to nearby objects may disrupt an
object with the Orbit Around behavior applied to it.
