    public ParticleSystemAnimationType animType;

    void Start()
    {

        var main = ps.main;
        main.startLifetimeMultiplier = 2.0f;

        var tex = ps.textureSheetAnimation;
        tex.enabled = true;
        tex.numTilesX = 4;
        tex.numTilesY = 2;
    }

    void Update()
    {
        var tex = ps.textureSheetAnimation;
        tex.animation = animType;
    }

    void OnGUI()
    {
        animType = (ParticleSystemAnimationType)GUI.SelectionGrid(new Rect(25, 25, 300, 30), (int)animType, new GUIContent[] { new GUIContent("WholeSheet"), new GUIContent("SingleRow") }, 2);
    }
