How to resume download #44

Open Friend-0x41 opened 4 years ago

Friend-0x41 commented 4 years ago

I use DownloadDependenciesAsync to download assets. It doesn't work when I reset network, I hold an AsyncOperationHandler and it's TaskStatus is WaittingToRun. How can I resume download or stop the AsyncOperationHandler. Thanks a lot!

Hi @Friend-0x41 unfortunately downloading pausing is not supported:

We use UnityWebRequest that does not support pausing. It is possible to create a completely new AssetBundleProvider implementation that is based on HttpClient and enable this. This would be fairly involved and in order to support streaming loads you would need to implement a custom memory stream that wrapped the one provided by HttpClient (this is due to the requirement that Seek is available in the stream).

你好，我也遇到这种问题，在微信小游戏中，偶尔会出现资源下载到90%几然后就一直不会继续下载了，status也没成功也没失败，完成回调也没有调用，请问这个要如何解决？我使用GetDownloadStatus()获取了下载长度，发现下载长度一直没有改变。

当时我的解决办法是重新再走一遍下载的逻辑，已下载的内容会被缓存，只下载需要更新的部分，当下载进度长时间不变就可以结束下载线程重新开始下载，但是addressable没有结束下载的接口（最新版本我不确定，接近三年没摸过了），需要更改addressable源码以结束下载进程
