1. 如需资源热更可以勾选此选项
2. 将需要加载的资源拖到Group下并修改Group的加载方式
2.1 将该Group的加载方式改为远程
3. 配置存储桶并修改Addressable的远程加载路径
以腾讯云为例各家对象存储页面可能有点差异，请自行查阅相关文档。
3.1 将访问权限改为公有读私有写
3.2 复制访问域名并修改Addressable的加载路径
[BuildTarget] 对应当前的平台
4. 完成上述操作后即可打包部署到对象存储桶
4.1 打包bundle
打包路径在AddressableAssetSettings可以查看，默认路径在项目的根目录
4.2 上传至对象存储桶（将打包好的文件夹整体上传）
5. 加载资源
5.1 制作下载进度条并将 DownloadProgressPanel 脚本挂到其父物体
using TMPro;
using UnityEngine;
using UnityEngine.UI;
public class DownloadProgressPanel : MonoBehaviour
{
public Image progressBarImage;
public TMP_Text progressTMP;
public TMP_Text downloadSizeTMP;
private void OnEnable()
{
progressBarImage.fillAmount = 0f;
progressTMP.text = "0%";
downloadSizeTMP.text = "资源下载中(0MB/0MB)";
}
}5.2 创建空物体并将 ResourceManager 挂到该物体上
using System;
using System.Collections;
using UnityEngine.AddressableAssets;
using UnityEngine.AddressableAssets.ResourceLocators;
using UnityEngine.ResourceManagement.AsyncOperations;
using UnityEngine.SceneManagement;

{

}

{
print("Addressable Initialization Complete");
