Axis: A pop-up menu that lets you specify whether the object aligns to its horizontal or
vertical axis.
Invert Axis: A checkbox that flips the orientation with which the object aligns to the
motion.
Spring Tension: A slider that adjusts how quickly the objects rotation changes to match
a change in the objects direction. Lower values create a delay between a change to an
objects position and its subsequent change in rotation. Higher values create more
responsive changes in rotation.
Drag: A slider that adjusts whether the change in rotation made by this behavior
overshoots the new direction of the object. Low drag values result in springy changes in
rotation, where the object rotates back and forth as it overshoots changes in direction.
High drag values dampen this effect, making the objects rotation stick more closely to
the changes made in rotation. Higher values also cause the object’s rotation to lag behind
the objects change in position.
HUD Controls
The HUD has controls for the Rotation Axis, Axis, Invert Axis, Spring Tension, and Drag
parameters. When applied to a group or layer that contains multiple objects (such as
particles, text, or a replicator), the Affect Subobjects checkbox also appears in the HUD.

Snap Alignment to Motion
Attracted To
This behavior is part of a group of Simulation behaviors that let you create complex
animated relationships between two or more objects. These behaviors are extremely
powerful and allow complicated effects to be created with a minimum of steps.
An object with the Attracted To behavior moves toward a single specified target, the
object of attraction. Additional parameters allow you to adjust the area of influence that
defines how close an object must be to move toward the object of attraction, and how
strongly it is attracted.
