ParticleSystem.EmissionModule.rateOverTimeMultiplier

描述

更改随时间变化速率乘数。

如果只想更改整体速率乘数，则此方法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 = 5.0f;

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

    void Update()
    {
        var emission = ps.emission;
        emission.rateOverTimeMultiplier = hSliderValue;
    }

    void OnGUI()
    {
        hSliderValue = GUI.HorizontalSlider(new Rect(25, 45, 100, 30), hSliderValue, 5.0f, 200.0f);
    }
}
