（請原諒任何格式問題）我正在嘗試獲得一個簡單的粒子系統來使用 OnTriggerEnter 并停止使用 OnTriggerExit。遵循粒子系統上的 Unity API ( https://docs.unity3d.com/ScriptReference/ParticleSystem.Play.html )。我開發了以下代碼：using System.Collections;using System.Collections.Generic;using UnityEngine;public class Electric_Trap_Trigger : MonoBehaviour{ParticleSystem system{    get    {        if (_CachedSystem == null)            _CachedSystem = transform.GetChild(0).gameObject.GetComponent<ParticleSystem>();        return _CachedSystem;    }}private ParticleSystem _CachedSystem;public bool includeChildren = true;//Start is called before the first frame updatevoid Start(){    if (system != null)        Debug.Log("Trap found");}// Update is called once per framevoid Update(){}private void OnTriggerEnter(Collider other){    if(other.gameObject.tag == "Player")    {        Debug.Log("Trap Triggered by: " + other.gameObject.tag);        if(system != null)        {            system.Play(includeChildren);        }    }}private void OnTriggerExit(Collider other){    if (other.gameObject.tag == "Player")    {        Debug.Log("Trap Exited by: " + other.gameObject.tag);        if (system != null)        {            system.Stop(includeChildren);        }    }}}正如你所看到的，我有調試代碼報告粒子系統已經找到并且玩家對象確實與盒子碰撞器交互。粒子系統不播放。任何幫助將不勝感激。
