ParticleSystem.forceOverLifetime

Description

访问粒子系统的生命周期力模块。

不需要将粒子系统模块重新分配回系统；它们是接口而不是独立的对象。

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void Start() {
        ParticleSystem ps = GetComponent<ParticleSystem>();
        var fo = ps.forceOverLifetime;
        fo.enabled = true;

        AnimationCurve curve = new AnimationCurve();
        curve.AddKey(0.0f, 0.1f);
        curve.AddKey(0.75f, 1.0f);
        fo.x = new ParticleSystem.MinMaxCurve(1.5f, curve);
    }
}
