idleDurationVariation
The range, in seconds, of randomized idle duration values. Animatable.
Declaration
var idleDurationVariation: CGFloat { get set }Discussion
Setting a nonzero value for this property randomizes the effect of the idleDuration property. For each idle period, SceneKit randomly adjusts the duration by up to half the idleDurationVariation value. For example, if the idleDuration value is 1.0 seconds and the idleDurationVariation value is 0.5 seconds, the system idles for a period of 0.75 to 1.25 seconds between emissions.
The default value is 0.0 seconds, specifying no randomization.
You can animate changes to this property’s value. See Animating SceneKit Content.
