public float startSizeXMultiplier ;

설명

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;

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); } }
