Particle axis constraints and render sorting

In the new 2D tools I found it hard to find information on using the particle system, so I wrote this little piece of code to help those who might want to lock the particles to a specific point in the z axis

Code (CSharp):

1.  
2. [AddComponentMenu("EffectsSystem/LockParticles")]
3. [RequireComponent(typeof(ParticleSystem))]
4. public class LockParticles : MonoBehaviour {
5.  
6.     public float Z = 0;
7.     public string SortLayerr = "";
8.     private ParticleSystem ps;
9.  
10.     // Use this for initialization
11.     void Start () {
12.         ps = GetComponent<ParticleSystem>();
13.         Renderer r = GetComponent<Render>();
14.         if(r != null && SortLayer != "")
15.                 r..sortingLayerName = SortLayer;
16.     }
17.    
18.     // Update is called once per frame
19.     void LateUpdate () {
20.         ParticleSystem.Particle[] par = new ParticleSystem.Particle[ps.particleCount];
21.         ps.GetParticles(par);
22.         for (int i = 0; i < par.Length; i++ )
23.         {
24.             par[i].position = new Vector3(par[i].position.x, par[i].position.y, Z);
25.         }
26.         ps.SetParticles(par, ps.particleCount);
27.     }
28. }

I hope this helps someone in the future
