frameRate
The rate, in frames per second, of the particle’s image animation.
Declaration
static let frameRate: SCNParticleSystem.ParticlePropertyDiscussion
This property’s value is a floating-point scalar (an NSNumber object for particle property controllers, or a single float value for particle event or modifier blocks). For details on particle image animation, see the particleImage property.
The particle system’s imageSequenceFrameRate and imageSequenceFrameRateVariation properties determine the initial animation speed for each particle.
