Space Warp B ehavior 1221
If you’ve selected multiple targets using Multiple
Selection (see next item), the word Multiple
appears on the button. To see which objects are
designated as targets, click the Multiple Selection
button.
Multiple Selection—Opens the Select dialog
to let you designate multiple targets. When you
have more than one target, you can set delegates to
move toward the closest ta rget in the group, or to a
computed average of the target positions.
Seek Target group
Determines seek activity when the behavior use s
multiple targets.
ClosestTargetOnly—Each delegate seeks the closest
oftheassignedtargets.Usethistohavedelegates
assigned a single Seek behav ior move in different
direct ions.
Av e rage Of Ta rgets—All delegates move toward
a common point determined by averaging all
targets’ locations.
Method group
Determines whether delegate direction as
influenced by the behavior is calculated by an
angularmethodoraforcemethod. Default=Angle.
Angle—Applies a force to the delegate based on the
angle b etween the delegate’s cur rent direct ion and
the direction it would need to take in order to be
moving directly toward the target.
The magnitude of the force is g reatest when the
delegate is moving away from the target, and needs
to turn around. It can be as little as 0 w hen the
delegate is directly approaching the target.
Force—Always applies a force directly towards the
target. The magnitude of the force is constant.
Radius group
Use the optional radius sett ings to act ivate the
Seek behavior only when the delegates are within
a specific distance from the target. The relat ive
strength of the Seek behavior increases from 0
percent beyond the outer radius to 100 percent at
the inner radius.
Use Ra d ii—When on, the Seek behavior applies
only to delegates less than the Outer Radius
distance from the target. Default=off.
Inner R adius—Thedistancefromthetargetat
which Seek is applied at full strength. Default=0.0.
Outer Ra diu s—Thedistancefromthetargetat
which Seek begins to be applied. Default=10.0.
Fa lloff—Default=2.0.
Display R adii—The radii are displayed when the
force is active.
Co lor Swatch—Shows the color used to draw the
Seek force vector during t he solution. Click the
box to choose a different color. Default=green.
Display Force—When on, force exerted on the
delegate(s) by the Seek behavior is drawn in
the viewports as a vector during the simulation
solution. If Use Radii is turned on, the radii are
also displayed when the force is ac tive.
