ParticleSystem.subEmitters

描述

访问粒子系统的子发射器模块。

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;

// A simple example showing access.

    public ParticleSystem mySubEmitter;

    void Start() {

        sub.enabled = true;
        sub.AddSubEmitter(mySubEmitter, ParticleSystemSubEmitterType.Death, ParticleSystemSubEmitterProperties.InheritNothing);
    }
