一、分组（网上教程一大堆）

二、构建

        构建前设置：

                1、分组设置。所有组做远端构建加载选择，RemoteBuildPath 。RemoteLoadPath

                 

                2、AddressableAssetSettings设置

         3、构建

                

 三、导出信息分析：

        1、Assets同级目录下，ServerData内，包含所有所需文件。

        2、对应平台下。catalog.hash和catalog.json为版本检测和资源记录文件。其他为AB包。

        3、Assets/AddressableAssetsData/Android下为热更记录文件，打热更包所需。

四、打热更包：

        

        选择上述三、3的文件。更新后ServerData下catalog和修改的AB发生变化。

五、地址重定向：

Addressables.ResourceManager.InternalIdTransformFunc = LoadFunc;

public static bool CustomNet { get; private set; }public static string VersionURL;public static string AddressURL;private static string OldUrl = "http://localhost/";/// <summary>/// 设置热更地址/// </summary>/// <param name="_versionUrl">版本地址</param>/// <param name="_addressUrl">资源地址</param>public static void SetCustomAddress(string _versionUrl, string _addressUrl){CustomNet = true;VersionURL = _versionUrl;AddressURL = _addressUrl;
#if UNITY_EDITORUnityEngine.Debug.Log("设置版本地址：" + VersionURL);UnityEngine.Debug.Log("设置资源地址地址：" + AddressURL);
#endifAddressables.ResourceManager.InternalIdTransformFunc = LoadFunc;}private static string LoadFunc(IResourceLocation location){if (location.ResourceType == typeof(IAssetBundleResource) && location.InternalId.StartsWith("http")){string abAddress = location.InternalId.Replace(OldUrl, AddressURL);return abAddress;   }return location.InternalId;}

 六、热更，创建服务器，把ServerData/Android放上去。即可热更。

        1、热更下载的catalog文件在 Application.persistentDataPath

        2、下载的AB资源在 ：C:\Users\Administrator\AppData\LocalLow\Unity

七、热更检测代码：
