  1. @override
void setLifespan(

See SingleChildParticle or ComposedParticle for details.

Implementation

@override
void setLifespan(double lifespan) {
  super.setLifespan(lifespan);

  if (applyLifespanToChildren) {
    for (final child in children) {
      child.setLifespan(lifespan);
    }
  }
}
