This behavior is similar to the Drag behavior, except that it affects Rotation instead of
position. Rotational Drag simulates friction affecting objects that are spinning due to
keyframed or behavior-driven changes to the Rotation parameter. By setting higher Drag
values, you can slow rotational changes to an eventual stop.
Parameters in the Inspector
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 selected, all objects in the parent object are affected
individually. When this checkbox is deselected, all objects in the parent object are affected
by the behavior together.
A slider that can be used to slow down an object’s rotation over time, causing
it to eventually come to a stop. Higher Amount values result in the rotation ending sooner.
The HUD lets you control the amount of drag. 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.
