Space Warp Behavior 1073
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 S election—Opens the Select dialog
to let y ou designate multiple targets. When you
have more than one t arget, you can set delegates to
move toward the closest t a rget in the group, or to a
computed average of the target positions.
Seek Target group
Determines seek activity when the behavior uses
multiple targets.
ClosestTargetOnly—Each delegate seeks the closest
oftheassignedtargets.Usethistohavedelegates
assigned a single Seek behav ior move in different
direct ions.
Av e ra ge O f Targ e ts—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 c alculated by an
angularmethodoraforcemethod. Default=Angle.
Angle—Applies a force to the delegate based on the
angle between the delegate’s current direction and
the direction it would need to take in order to be
moving directly toward the target.
The magnitude of the force is greatest when the
delegate is moving away from the target, and needs
to turn around. It can be as little as 0 when the
delegate is directly approaching the target.
Force—Always applies a force directly towards the
target. The magn itude of the force is constant.
Radius group
Use the optional radius sett ings to activate the
Seek behavior only when the delegates are within
a specific distance from the target. The relative
strength of the Seek behavior increases from 0
percent beyond the outer radius to 100 percent at
the inner radius.
Use R a di i—When on, the Seek behavior applies
only to delegates less than the Outer Radius
distance from the target. Default=off.
Inner Ra dius—Thedistancefromthetargetat
which Seek is applied at f ul l strength. Default=0.0.
Outer Radi us —Thedistancefromthetargetat
which Seek begins to be applied. Default=10.0.
Fa lloff—Default=2.0.
Display Ra dii—The radii are displayed when the
force is active.
Co lor Swatch—Shows the color used to draw the
Seek force vector during the 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 viewpor ts as a vector during the simulation
solution. If Use Radii is turned on, the radii are
also displayed when the force is active.
