Using Behaviors
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.
Rotation Axis: A pop-up menu that lets you rotate the object around the X, Y, or Z axis.
You can also select All to rotate the object around all three axes. The default rotation
axis is Z.
Axis: A pop-up menu that lets you specify whether the object aligns itself on its
horizontal or vertical axis.
Invert Axis: A checkbox that flips the orientation with which the object aligns itself to
the motion.
Spring Tension: A slider that adjusts how quickly the object’s rotation changes to
match a change in the object’s direction. Lower values create a delay between a
change to an object’s position and its subsequent change in rotation. Higher values
create more responsive changes in rotation.
Drag: A slider that adjusts whether or not 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 object’s rotation stick
more closely to the changes made in rotation. Higher values also cause the object’s
rotation to lag behind the object’s change in position.

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.
