Wall Seek Behavior 1081
specific distance from the target. The relative
strength of the behavior increases from 0 percent at
the outer radius to 100 percent at the inner radius.
Use Di stance—When on, the behavior applies only
to delegates closer to the target than the Outer
Distance value. Default=on.
Inner Di sta nce—The distance from the target
at which the force is applied at full strength.
Default=0.0.
Outer Distance—Thedistancefromthetargetat
which the force beg ins to b e applied. Default=10.0.
Fa lloff—Therateatwhichtherepellingforce
diminishes between the Inner Distance and the
Outer Distance. Default=2.0.
A va lue of 1.0 indicates a linear falloff. Higher
values cause the strength to fa ll off to zero more
rapidly with distance, thus focusing its effect
closer to the Inner Distance. Lower va lues reduce
the rate of diminishment, with a Falloff setting of
0.0indicatingthatthestrengthisthesameatthe
Outer Distance as it is at the Inner Distance.
Display Distance—Shows the inner and outer
distance settings as g rids offset f rom the t arget grid
in the viewports. The Inner Distance grid is light
blue, while the Outer Distance grid is blue-white.
Default=on.
Grid Spacing—Alters the spacing of grid lines used
to draw the Inner/Outer Distance grids. The lower
the v alue, the closer the spacing. D efault=500.
End force at grid edges——When on, the force
emanates only from the grid object. When off,
the force emanates from an imaginar y infinite
grid created by extending the grid plane in a ll
direct ions.
Co lor Swatch——Shows the color used to draw the
Wall Repel force during the s olut ion . Click the box
to choose a different color. Default=violet.

The Wall Seek behavior uses a grid object to attract
delegates. When influenced by the Wall Seek
force, delegates turn until they’re heading toward
the g rid. It’s useful for moving objects toward a
rectangular area, such as a doorway.
You can set the grid to attract from e ither side or
both sides, and optionally specif y a maximum
distance for attraction. You can also set the
behavior to act as though the gr id extends
infinitely along its plane.
