In this lecture I guess I was expecting (given that the term “emitter” was used) that we’d spawn a particle system and then trigger its effect to start whenever the gun fire method was called. Instead it seems that we create the particle system on each firing of the gun. I assume that once the system is finished its effect, it is garbage collected but it also seems a bit wasteful to continually create new ones on every firing.
Is there a way to just create it once and then trigger it? If so, is there an advantage to one or the other method?
