3D Graphs in Unity

Hey folks,

I'm trying to follow CatlikeCoding's tutorial on 3d graphs in unity. However seems that some features are deprecated. Disclaimer: I'm not terribly experienced with unity. Here's the tutorial: http://catlikecoding.com/unity/tutorials/graphs/#a-questionmark

Rn i'm at this step of her tutorial:

Code (CSharp):

1. void Start () {
2.  
3.  
4.         if (resolution < 10 || resolution > 100) {
5.             Debug.LogWarning ("Grapher resolution is out of bounds, resetting to minimum.", this);
6.             resolution = 10;
7.        
8.             float increment = 1f / (resolution - 1);
9.             for (int i = 0; i < resolution; i++) {
10.                 float x = i * increment;
11.                 points [i].position = new Vector3 (x, 0f, 0f);
12.                 points [i].color = new Color (x, 0f, 0f);
13.                 points [i].size = 0.1f;
14.  
15.             }
16.             points = new ParticleSystem.Particle[resolution];
17.  
18.         }
19.     }
20.     // Update is called once per frame
21.     void Update () {
22.         particleSystem.SetParticles(points, points.Length);
23.  
24.  
25.     }
26. }
27.  

My error is at the line inside of Update(). This is deprecated. So i replaced it by doing:

particles = GetComponent <ParticleSystem> ();
(inside of Start)

Then in update i used: particles.SetParticles(points, points.Length);

However i'm getting an object reference not set to an instance of object error pointing to my Update function. Any help would be appreciated.

 

So i've got

Code (CSharp):

1. public ParticleSystem particleSystem;

at the top before start.

Then inside of start I have:

Code (CSharp):

1. particleSystem = GetComponent<ParticleSystem>();

then in Update I have:

Code (CSharp):

1. particleSystem.SetParticles(points, points.Length);

It's still throwing the null reference error at the last line in Update.

 

Hmm, it is infact attached to the particle system. I created the component within the particle and it shows up in the inspector.
