| 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 | @param withChildren Также очистить все дочерние системы частиц. |
| 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. |
Fastforwards the particle system by simulating particles over given period of time, then pauses it.
