◆ useRandomSeed()

bool QQuick3DParticleSystem::useRandomSeed ( ) const

\qmlproperty bool ParticleSystem3D::useRandomSeed

This property defines if particle system seed should be random or user defined. When true, a new random value for \l {ParticleSystem3D::seed}{seed} is generated every time particle system is restarted.

The default value is true.
