Instance Property

usesEllipsoidalExtent

A Boolean value that determines whether the field’s area of effect is shaped like a box or ellipsoid.

Declaration

var usesEllipsoidalExtent: Bool { get set }

Discussion

If this value is false (the default), the field’s area of effect is the box-shaped region of space defined by its halfExtent property and the position property of the node containing the field.

If this value is true, the field’s area of effect is the ellipsoid bounded by this box-shaped region. That is, if all components of the half-extent vector are equal, the field has a spherical area of effect.
