Using Behaviors
Falloff Type: A pop-up menu that determines whether the distance defined by the
Influence parameter falls off linearly or exponentially.
 Linear: Object attraction falls off in proportion to the object’s distance.
 Exponential: The closer an object is within the area of influence, the more strongly it
is attracted, and the faster it moves toward the object of attraction.
Falloff Rate: This value determines how quickly the force of attraction between
objects affected by this behavior falls off. A low Falloff Rate value results in objects
quickly getting up to speed as they move toward the object of attraction. A high Falloff
Rate causes objects to accelerate much more slowly. When set to Exponential, the
attraction falls off more quickly than when set to Linear.
Influence: A slider that defines the radius of the circle of influence, in pixels. Objects
that fall within the area of influence move toward the object of attraction. Objects that
are outside of the area of influence remain in place.
Drag: A slider that can be used to reduce the distance attracted objects overshoot the
object of attraction. Lower Drag values result in the object overshooting the object of
attraction, moving past and then careening back around toward the target object
again and again. Higher Drag values result in the object coming to rest sooner.
Include X, Y, and Z: Buttons that allow you to specify the axes on which the affected
object (or objects) moves around the object to which it is attracted. When Z is enabled,
the object moves about its attractor object in Z space.

Attractor
If you apply an Attractor behavior to an object, other objects that lie within the area of
influence move toward it. You can manipulate the strength with which other objects
are attracted, as well as the distance required for attraction to begin.
