Instance Property

minimumDistance

The minimum value for distance-based effects.

Declaration

@property(nonatomic) CGFloat minimumDistance;

Discussion

This property determines the beginning of the field’s falloff area. At distances less than the minimum, the field’s effect is at full strength. At greater distances, the field’s effect diminishes based on the value of the falloffExponent property. The default minimum distance is a very small (but nonzero) value.

strength

falloffExponent

An exponent that determines how the field’s strength diminishes with distance.

active

A Boolean value that determines whether the field’s effect is enabled.

exclusive

A Boolean value that determines whether the field overrides other fields whose areas of effect it overlaps.
