Depth of particles

[dp]

I'm struggling to alter the depth of my particles, and after endless
searching just cant seem to crack it. Does anyone know how to change
the depth of them?

I create a particle

new Custom Particle (extends rectangle particle)

setDisplayOffset(d, 0, 0);

d = new CustomGraphic() (extends Sprite)


but what ever method I try they all keep the depth order they are
created in.

thanks
