Strength: A slider defining the speed with which attracted objects move toward the
target object. With a value of 0, attracted objects don’t move at all. The higher the value,
the faster attracted objects move.
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 objects 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 Falloff Type is 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 outside
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) drift toward the target object. For example, when X and Y are enabled, the object
drifts in the XY plane; when Y and Z are enabled, the object drifts in the YZ plane.
