Hello,

I am attempting to work through this tutorial: http://catlikecoding.com/unity/tutorials/graphs/ . When it gets to the part of writing the ParticleSystem call:

void Update () {
particleSystem.SetParticles(points, points.Length);
}

I get an error. I am not sure what to input at this point to get the particles to actually begin firing. This is everything so far:

2 separate errors on ParticleSystem and SetParticles respectively.
