ParticleSystem.MainModule.startSizeXMultiplier

Description

A multiplier for ParticleSystem.MainModule.startSizeX.

Changing this property is more efficient than accessing the entire curve, if you only want to change the overall size multiplier.

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(ParticleSystem))]
public class ExampleClass : MonoBehaviour
{
    private ParticleSystem ps;
    public float hSliderValue = 1.0F;

    void Start()
    {
        ps = GetComponent<ParticleSystem>();

        var main = ps.main;
        main.startSize3D = true;
    }

    void Update()
    {
        var main = ps.main;
        main.startSizeXMultiplier = hSliderValue;
    }

    void OnGUI()
    {
        hSliderValue = GUI.HorizontalSlider(new Rect(25, 45, 100, 30), hSliderValue, 0.0F, 10.0F);
    }
