464 Chapter 5 Using Behaviors
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 space in which the object (or
objects) moves toward the target object. For example, when X and Y are enabled, the
object moves in the XY plane; when Y and Z are enabled, the object moves in the YZ
plane.

Drag
This behavior lets you simulate the force of friction on a moving object, slowing it
down over time. Applying the Drag behavior is an easy way to decelerate objects with
multiple behaviors that create complex motion.
HUD Control
The HUD lets you adjust the amount of drag and axis assignment. When applied to an
object that contains multiple objects, such as a group, particles, text, or the replicator,
the Affect Subobjects checkbox also appears in the HUD.
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 turned on, all objects within the parent object are affected
individually. When this checkbox is turned off, all objects within the parent object are
affected by the behavior together, as if they were a single object.
Amount: Sliders that can be used to slow down an object over time, causing it to
eventually come to a stop. Higher Drag values result in the object coming to rest
sooner. Click the Amount disclosure triangle to adjust the drag applied to the X, Y, and
Z values separately. An example of this is to create a situation where an object’s vertical
speed slows down faster than its horizontal speed.
