You can also set the Acceleration parameter to a negative value, effectively applying
“anti-gravity” to the object and making it fly up.
Parameters in the Inspector
Affect Subobjects: This parameter appears when this behavior is applied to an object
that contains multiple objects, such as a group, a particle emitter, a replicator, or a text
layer. When this checkbox is selected, all objects in the parent object are affected
individually. When this checkbox is deselected, all objects in the parent object are affected
by the behavior together.
Acceleration: A slider defining the strength of gravity affecting the target object. The
higher this value, the faster the target object falls.
HUD Controls
The HUD lets you adjust the Acceleration parameter. When applied to an object containing
multiple objects (such as a group, particles text, or a replicator), the Affect Subobjects
checkbox also appears in the HUD.

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 might disrupt an
object with the Orbit Around behavior applied to it.
