How to make a particle system activate

[GreyFox]

Hey, I understand theres the command

CreateParticleSystemAtEntity, but the thats not what I want.

I want to open a door and have a gust of wind/dust just blow down the hall. Would I do

SetEntityPlayerInteractCallback(string& asName, string& asCallback, bool abRemoveOnInteraction);

and then do PreloadParticleSystem(string& asPSFile);?

What does PreloadParticleSystem even do? (well preload it but what do that do?)

Is there a simple way of doing it.
