Unity Addressable热更系统尝试(一)

受启发: Addressable 增量包

Addressable Setting中勾选

 制作资源

 设置定好资源的热更

 下面是检测更新代码和加载资源

[SerializeField]
    private string _entryName = "Assets/Prefab/GameObject.prefab";

    public Text UpdateLb;
    // Start is called before the first frame update
    void Start()
    {
        //var _ = StartAsync();

        StartCoroutine(DoUpdateAddressadble());
    }

    IEnumerator DoUpdateAddressadble()
    {
        AsyncOperationHandle<IResourceLocator> initHandle = Addressables.InitializeAsync();
        yield return initHandle;

        var checkHandle = Addressables.CheckForCatalogUpdates(false);
        yield return checkHandle;
        if (checkHandle.Result.Count > 0)
        {
            var updateHandle = Addressables.UpdateCatalogs(checkHandle.Result, false);

            yield return updateHandle;

            List<IResourceLocator> locators = updateHandle.Result;
            foreach (var locator in locators)
            {
                List<object> keys = new List<object>();
                keys.AddRange(locator.Keys);
                var sizeHandle = Addressables.GetDownloadSizeAsync(keys);
                yield return sizeHandle;
                long totalDownloadSize = sizeHandle.Result;
                UpdateLb.text = UpdateLb.text + "
download size : " + totalDownloadSize;
                Debug.Log("download size : " + totalDownloadSize);
                if (totalDownloadSize > 0)
                {
                    var downloadHandle = Addressables.DownloadDependenciesAsync(keys);
                    while (!downloadHandle.IsDone)
                    {
                        float percentage = downloadHandle.PercentComplete;
                        Debug.Log($"已下载: {percentage}");
                        UpdateLb.text = UpdateLb.text + $"
已下载: {percentage}";
                        yield return null;
                    }
                    Debug.Log("下载完毕!");
                    UpdateLb.text = UpdateLb.text + "
下载完毕" ;
                    Addressables.Release(downloadHandle);
                }
            }
            Addressables.Release(updateHandle);
        }
        else
        {
            UpdateLb.text = UpdateLb.text + "
没有检测到更新";
        }
        Addressables.Release(checkHandle);


        Load();
    }
    void Load()
    {
        Addressables.LoadAssetAsync<GameObject>(_entryName).Completed +=
            (op) =>
            {
                if (op.Status == AsyncOperationStatus.Succeeded)
                {
                    Debug.Log(op.Result as GameObject);
                    var go = Instantiate(op.Result as GameObject, Vector3.zero, Quaternion.identity, transform);
                    go.transform.localPosition = Vector3.zero;
                    go.transform.localScale = Vector3.one;
                }
            };
    }

原文是打了Log,我为了方便查看加了一个Text
将Addressable资源build好上传远程

工程打包,这里我打了pc包

运行

======================================================================

好的,这里出了事故

第一次运行之后显示了加载更新4039,刚好和资源大小一致,但是我直接关了进程想看看第二次打开会不会更新,没有更新但是第一次的更新没截图=  =

然后悲催的我想重新打个包应该就行了,结果是

我就不淡定了,我包是重新打了,讲道理应该会重新更新才对,

于是我把包又重新删掉,远程的资源也删了,按照上面的流程重新操作一遍

结果.... 只显示更新size 为0

裂开了.....我在重新尝试中.......

 想到一个办法,我要坑同事了,哈哈哈..

 果然,成功截图..

在我几次尝试后,有这么个疑问:

现象:更新过后,不管我是把包删除重新build,还是把远程资源都删掉,都会显示无更新

但是我把新加的资源和原有的资源(新打的),一起传到远程,他只会更新新加的,但是原有的资源也是可以正常加载出来的

问题:他是把资源更新加载到电脑内存里面吗,我重新打包和删除远程资源无效,是因为更新还在内存中吗?
