Include X, Y, and Z: Buttons that allow you to specify the space in which drag is in
effect. For example, when X and Y are enabled, the object drags in the XY plane; when
Y and Z are enabled, the object drags in the YZ plane.
Related Behaviors

Rotational Drag ”
Drift Attracted To
Similar to the Attracted To behavior, but by default an object moves toward the object
of attraction and comes to rest, rather than overshooting the object of attraction and
bouncing around.
HUD Control
The HUD has an object well you can use to assign an object of attraction, sliders for
strength and 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.
Object: A well that defines the object of attraction. To set the defined target object,
drag the object from the Layers tab to the object well in the Drift Attracted To HUD or
Inspector. In the Layers tab, you can also drag the target object onto the Drift Attracted
To behavior.
Strength: A slider defining the speed at which the object moves toward the object of
attraction. With a value of 0, the object doesn’t move at all. The higher the value, the
faster the object moves.
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.
