Chapter 5 Using Behaviors 483
When you click the 3D button, the HUD allows you to use the center arrow control to
define the direction the object is “blown” by the wind in 3D. The Speed slider (on the
left side of the HUD) lets you increase or decrease the velocity of the blown object.
Note: The maximum speed you can define with the HUD is not the maximum speed
possible. Higher values can be entered into the Velocity parameter in the Behaviors tab
of the Inspector.
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.
Air Thickness: A slider and value slider that adjusts how fast the object accelerates on
the X, Y, or Z axis when the speed is changed. Lower values (simulating thinner air)
have less effect when pushing the object, so it takes longer to get up to speed. Higher
values (thicker air) have more effect and push the object up to speed more quickly.
Velocity: A slider and value slider that adjust the speed on the X, Y, or Z axis at which
the simulated air is blowing the object. Higher values result in faster motion.

Behavior Examples
The following examples illustrate different ways that groups of behaviors can be
combined to create different effects.

wind.
Adjusts the direction of
the wind in X, Y, and Z.
