HUD Controls
An image well in the HUD lets you set the Attract To object. You can also control the
Spring Tension and Relaxed Length parameters and axis assignment. A checkbox lets you
turn on the Repel parameter. When this behavior is 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.

Vortex
The opposite of the Orbit Around behavior. Whereas the Orbit Around behavior causes
one object to orbit around another target object, the Vortex behavior exerts a force on
all objects surrounding the object to which the Vortex behavior is applied.
Parameters in the Inspector
Affect: A pop-up menu that limits which objects in your project are affected by the Vortex
behavior. There are three options:
All Objects: All objects in the Canvas are affected by the Vortex behavior.
Related Objects: The default setting. Only other objects in the same group as the object
of attraction are affected.
Specific Objects: Only objects appearing in the Affected Objects list are affected by the
Vortex behavior.
Affected Objects: A list that appears when Specific Objects is chosen in the Affect pop-up
menu. Drag objects from the Layers list into this list to be affected by the Attractor behavior
when the Specific Objects option is selected in the Affect pop-up menu. To remove an
item from the list, select the item and click Remove.
Layer: This column lists the name of the layer containing the object.
Name: This column lists the name of the object.
Strength: A slider defining the speed at which the affected objects move about the object
of attraction.
Falloff Type: A pop-up menu that determines whether the distance defined by the
Influence parameter falls off linearly or exponentially. The default is Linear.
Linear: Object attraction falls off in proportion to the objects distance.
