Note:
The Wall Repel behavior simply applies a
force on the delegate in the direction opposite
the wal l; it does not g uarantee that the delegate
won’tgothroughthewall.Ifthedelegatedoesgo
through the wall, adjust settings such as Inner and
Outer Distance, and, in particular, try reducing
Falloff.
Inter face
Grid fr om which to repel——Set a repelling g rid
("source")byclickingtheNonebuttonandthen
selecting the grid. Thereafter, the grid’s name
appears on the button.
Tosetmultiplesourcegrids,clickMultiple
Selection and use the Select dialog. With multiple
source grids, the word "Multiple" appears on the
large button.
Method group
Determines whether delegate direction as
influenced by the behav ior i s calculated by an
angularmethodoraforcemethod.Default=Force.
Angle—Applies a force to the delegate based on t he
angle between 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 g reatest 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 away from
the source.
Force—Always applies a force directly away from
the source. The magnitude of the force is constant.
Direction group
Determines whether the grid repels from its
positive-axis side, its negative-axis side, or both.
To determine which is the positive-axis side, select
the grid, and then set the reference coordinate
system to Local (the default system is View).
Look at the grid in a viewport in which it appears
edge-on. Thesidewiththeaxisstickingoutis
the positive-axis side, and the opposite side is t he
negative-axis side.
Tip: For ease of setup, when building a "room"
from grids, make sure they all point inward (or
outward).
Posi ti ve A x i s—The grid repels only from the
positive-axis side.
Negati ve Axis —The grid repels only from the
negative-axis side.
Both Axes—The grid repels from both sides.
Distance group
Use the dist ance sett ings to activate the Wa l l Repel
behavior only when the delegates are within a
