Repel Behavior 1071
Inter face
None (la bel)—Specifies a single source. Click this
button, and then click the target object in the
viewport. The target name then appears on the
button.
If you’ve selected multiple sources using Multiple
Selection (see next item), the word Multiple
appears on the button. To see which objects are
designated as sources, click the Multiple Selection
button.
Multiple S election—Opens the Select dialog to let
you designate multiple sources. When you have
more than one s ource, you can set delegates to
move toward the closest t a rget in the group, or to a
computed average of the source positions.
Source of Repulsion group
Determines repel a ctivity when the b ehavior uses
multiple sources. The default choice is Closest
Source Only.
Close st Sou r ce Only —Each delegate is repelled by
the closest of the assigned sources. Use this to have
delegates assigned a single Repel behavior move
away from sources in different directions.
Av e ra ge Of So urce s—All delegates move away from
a common point determined by averaging all
sources’ locations.
Method group
Determines whether delegate direction as
influenced by the behavior is calculated by an
angularmethodoraforcemethod.Default=Force.
Angle—Applies a force to t he delegate based on the
angle b etween the delegate’s current direction and
the direction it would need to take in order to be
moving directly away from the source.
The magnitude of the force is greatest when the
delegate is moving directly towards the source,
and needs to turn around. It can be as little as 0
when the delegate is moving directly aw ay from
the source.
Force—Always applies a force directly away from
the source. The magnitude of the force is constant.
Radius group
Use the Radius settings to activate the Repel
behavior only when the delegates are within a
specific distance from the target. The relative
strength of the force increases from 0 percent at
the outer radius to 100 percent at the inner radius.
Use Radii—When on, the behavior applies only
to delegates closer to the target than the Outer
Distance value. D efault=on.
Inner R adius—Thedistancefromthetarget
at which the force is applied at full strength.
Default=0.0.
Outer Radi us —Thedistancefromthetargetat
which the force begins to be applied. D efault=10.0.
