ParticleSystem.MainModule.startLifetimeMultiplier

切换到手册
public float startLifetimeMultiplier ;

如果只想更改整体生命周期乘数,则更改该属性比访问整条曲线更加高效。

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>(); }

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

void OnGUI() { hSliderValue = GUI.HorizontalSlider(new Rect(25, 45, 100, 30), hSliderValue, 0.0F, 5.0F); } }
