withChildren

Check all child particle systems as well.

Returns
bool True if the particle system is still "alive", false if the particle system is done emitting particles and all particles are dead.

Does the system have any live particles (or will produce more)?

	// of a particle effect. It will destroy the gameobject and its children.
