Global Variable


The rotation angle, in radians, of the particle about its axis.


const SCNParticleProperty SCNParticlePropertyAngle;


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).

The particle system’s particleAngle and particleAngleVariation properties determine the initial rotation for each particle. The SCNParticlePropertyRotationAxis property defines the particle’s rotation axis.
