The magnitude of the force is greatest 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. The side with the axis sticking
out is the positive-axis side, and the opposite side is the negative-axis side.
TIP For ease of setup, when building a "room" from grids, make sure they all point
inward (or outward).
Positive Axis The grid repels only from the positive-axis side.
Negative Axis The grid repels only from the negative-axis side.
Both Axes The grid repels from both sides.
Distance group
Use the distance settings to activate the Wall Repel behavior only when the
delegates are within a 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 Distance When on, the behavior applies only to delegates closer to the
target than the Outer Distance value. Default=on.
Inner Distance The distance from the target at which the force is applied at
full strength. Default=0.0.
Outer Distance The distance from the target at which the force begins to be
applied. Default=10.0.
Falloff The rate at which the repelling force diminishes between the Inner
Distance and the Outer Distance. Default=2.0.
A value of 1.0 indicates a linear falloff. Higher values cause the strength to
fall off to zero more rapidly with distance, thus focusing its effect closer to
the Inner Distance. Lower values reduce the rate of diminishment, with a
