파라미터

t	Time period in seconds to advance the ParticleSystem simulation by. If `restart` is true, the ParticleSystem will be reset to 0 time, and then advanced by this value. If `restart` is false, the ParticleSystem simulation will be advanced in time from its current state by this value.
withChildren	Fast-forward all child Particle Systems as well.
restart	Restart and start from the beginning.
fixedTimeStep	Only update the system at fixed intervals, based on the value in "Fixed Time" in the Time options.

Fast-forwards the Particle System by simulating particles over the given period of time, then pauses it.
