public ParticleSystemSortMode sortMode;

Description

Specifies how to sort particles within a system.

using UnityEngine;
using UnityEditor;
using System.Collections;

public class ExampleClass : MonoBehaviour {

private ParticleSystem ps; private ParticleSystemRenderer psr; public ParticleSystemSortMode sortMode;

void Start() {

ps = GetComponent<ParticleSystem>(); psr = GetComponent<ParticleSystemRenderer>();

// set a slow start speed and high emission rate, to cause more overlap, to show sorting var main = ps.main; main.startSpeedMultiplier = 0.2f; var emission = ps.emission; emission.rateOverTimeMultiplier = 100.0f;

// set color over life, so we can see the sorting more easily var colorOverLifetime = ps.colorOverLifetime; colorOverLifetime.enabled = true;

Gradient gradient = new Gradient(); gradient.SetKeys( new GradientColorKey[] { new GradientColorKey(Color.green, 0.0f), new GradientColorKey(Color.red, 1.0f) }, new GradientAlphaKey[] { new GradientAlphaKey(1.0f, 0.0f), new GradientAlphaKey(1.0f, 1.0f) } );

colorOverLifetime.color = new ParticleSystem.MinMaxGradient(gradient); }

void Update() {

psr.sortMode = sortMode; }

void OnGUI() {

sortMode = (ParticleSystemSortMode)GUI.SelectionGrid(new Rect(25, 25, 900, 30), (int)sortMode, new GUIContent[] { new GUIContent("None"), new GUIContent("Distance"), new GUIContent("OldestInFront"), new GUIContent("YoungestInFront") }, 4); } }
