ParticleSystem.emission

Description

访问粒子系统的发射模块。

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。

// Create a particle system
// At 2 and 4 secs the number of particles are changed to 100, then 200
using UnityEngine;
using System.Collections;

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

        em.type = ParticleSystemEmissionType.Time;

        em.SetBursts(
            new ParticleSystem.Burst[]{
                new ParticleSystem.Burst(2.0f, 100),
                new ParticleSystem.Burst(4.0f, 100)
            });
    }
}
