The delayed stop of a ParticleEventData effect
(ParticleEventData.AdditionalKillConfig). Without it, the effect is stopped at once when the event ends. With
it, the effect keeps playing for a time after the event has ended, and is stopped
then.
Bool = true When true, which is the default, the delay applies only after the clip has stopped. If the clip of the event still plays, or plays again, when the event ends, the effect is stopped at once. When false, the delay always applies.
F32 = 0 The time from the end of the event to the stop of the effect, in seconds.
