Question by fingerpw · Dec 09, 2020 at 12:34 PM · assetbundle

Pre-download assets using addressable system

Pre-download assets using addressable system

We are considering introducing an addressable system.

I need to show the download size and download progress at a specific time when running the application.

So, I want to download all assetbundle(assetgroup) at once.

Addressable labels will not be used.

So what I thought was that each bundle group created a dummy asset with the same name as the bundle group

I plan to make a list of bundle groups, download the list, GetDownloadSizeAsync at once, and then run DownloadDependenciesAsync.

The code is below.

 // assetgroup list download from web server
 string[] assetList;
 ...
 
 // calculate all asset size
 long assetSize = 0
 for(int i = 0; i < assetList.Length; ++i)
 {
     Addressables.GetDownloadSizeAsync(assetList[i]).Completed +=
         (handle) =>
         {
             assetSize += handle.Result;
         };
 }
 
 // download all asset
 for (int i = 0; i < assetList.Length; ++i)
 {
     Addressables.DownloadDependenciesAsync(assetList[i]).Completed +=
         (handle) =>
         {
             ...
         };
 }

Is there a problem with using it this way? Or is there a recommended or better way?
