ParticleSystem.MainModule.useUnscaledTime

描述

如果为真，则使用未缩放的 Delta 时间来模拟粒子系统。否则，使用缩放的 Delta 时间。

这在游戏暂停且 [[Time.timeScale] 设置为零时播放特效很有用。

using UnityEngine;
using System.Collections;

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

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

    void Update()
    {
        var main = ps.main;
        main.useUnscaledTime = useUnscaledTime;

        Time.timeScale = hSliderValue;
    }

    void OnGUI()
    {
        GUI.Label(new Rect(25, 40, 100, 30), "Time Scale");
        hSliderValue = GUI.HorizontalSlider(new Rect(105, 45, 100, 30), hSliderValue, 0.0F, 10.0F);
        useUnscaledTime = GUI.Toggle(new Rect(25, 75, 100, 30), useUnscaledTime, "Use Unscaled Time");
    }
