minimumRadius
The minimum distance at which to start calculating new values for the field.
Declaration
var minimumRadius: CGFloat { get set }Discussion
Use this property to modify the behavior of distance-based effects when objects are close to the center of the field. Distances that are less than the minimum value are treated as if they are equal to the minimum value. In addition, effects such as falloff are not applied until the minimum distance is reached.
The default value of this property is very small, but not zero.
