ParticleSystem.ForceOverLifetimeModule.xMultiplier

描述

定义 x 轴乘数。

如果只想更改整体 x 轴乘数，则更改该属性比访问整条曲线更加高效。

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    private ParticleSystem ps;
    public bool moduleEnabled = true;
    public float hSliderValue = 10.0f;

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

    void Update()
    {
        var forceOverLifetime = ps.forceOverLifetime;
        forceOverLifetime.enabled = moduleEnabled;
        forceOverLifetime.xMultiplier = hSliderValue;
    }

    void OnGUI()
    {
        moduleEnabled = GUI.Toggle(new Rect(25, 45, 100, 30), moduleEnabled, "Enabled");
        hSliderValue = GUI.HorizontalSlider(new Rect(25, 85, 100, 30), hSliderValue, -50.0f, 50.0f);
    }
}
