Particle problem

I am using this particle emitter code to produce particles:

https://github.com/downloads/Oskwish/Corona-SDK-codes/particle%20emitter.zip

Don’t know where I found it so I can’t contact the creator.

What I want is to be able to control if the particles should be on front or in the back of my layers. I can’t figure out how to use the :toFront() or :toBack()

To use it, write this in your main.lua file:

[code]

particles = require(“iParticleFX”)
