Question about Addressables.DownloadDependenciesAsync exception handling

Unity Engine
1

When using DownloadDependenciesAsync to get dependency resources with key(string), if there is no resources with provided key, exception is shown as follows.

Exception encountered in operation CompletedOperation, status=Failed, result= : Exception of type 'UnityEngine.AddressableAssets.InvalidKeyException' was thrown., Key=MG_Destruction, Type=System.Object
UnityEngine.AddressableAssets.Addressables:smile:ownloadDependenciesAsync(Object, Boolean)

There is a possible case that dependency resource might not exists, so if that exception is thrown, then I just want to ignore that exception and not to show on logger.

But I can’t find a way to not show that exception. try catch doesn’t work because DownloadDependenciesAsync is asynchronous method.

Or if there is CheckDependencyAsync i could check before downloading it.

Is there any way I could not show that exception if there is no dependency?

I think you want to try using Addressables.LoadResourceLocationsAsync before each Download operation.

First, pass your key/s into LoadResourceLocationsAsync and await the result. Even if the key is invalid, it’ll always return a List which you can then check the count of. If its 0, skip that download :slight_smile:

It works like magic!

Thanks for the fast reply.
