Enable/Disable of Particles through script

I’m pretty sure that this is the what I’m trying to do is bead easy, but I can for my life figure it out. I’m trying to to make a trigger that when the player enters will enable a flame particle to appear.
Now I don’t know much about scripting, to be honest I’m really weak at scripting, but I’m sure that getting a particle (and or game-object) to appear when the player enters a trigger isn’t hard at all. SO any help anyone can give would be great. Thanks.

Additionally I’m using Unity Script.

If you are have Particle System component in your gameobject, you can use Play(), Stop(), Pause().

This is what you need in your js-file:

function OnTriggerEnter (other : Collider) {

function OnTriggerExit (other : Collider) {
