Grid Spacing Alters the spacing of grid lines used to draw the Inner/Outer
Distance grids. The lower the value, the closer the spacing. Default=500.
End force at grid edges When on, the force emanates only from the grid
object. When off, the force emanates from an imaginary infinite grid created
by extending the grid plane in all directions.
Color Swatch Shows the color used to draw the Seek force vector (and, if used,
the radii) during the solution. Click the box to choose a different color.
Default=violet.
Display Force When on, force exerted on the delegates 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 active.

Behavior
The Wander behavior imparts a random motion to delegates, letting you
simulate meandering activity in which delegates move and turn in a haphazard
manner. It works by randomly picking a new direction, and then turning and
moving in that direction. You can specify how often to pick a new direction,
how far to turn, and how fast or slow to turn while moving.
TIP The trajectory calculated by the Wander behavior varies significantly for each
object to which it's applied. To create a group of wandering delegates all using
the same trajectory, apply the Wander behavior to a delegate, solve the simulation,
and then replicate the delegate using the
Scatter Objects on page 4823 facility with
Clone Controllers turned on.
Procedures
To use the Wander behavior:
1 Add a Wander behavior to the Crowd object.
2 Change the default settings as desired. Probably the most important is
Period, which sets the number of frames between changes of direction.
