Release an Addressable Asset issues
Hey folks,
I'm having a couple of issues with releasing Addressable assets. I've tried 2 approaches to perform the release operation: 1. call my AssetReference.Release() 2. call Addressables.Release() with the handle returned from Addressables.LoadAssetAsync<T>
Both methods do not seem to work as seen in the attachments.
I also tried to print the Addressables.GetDownloadSizeAsync(key).Result; and as seen in the 2nd attachment even after "releasing" the asset, the memory is still retained (size 0 means the asset is cached).
Here is the full code:
public class AddressablesAssetService : IAssetService
{
private readonly Dictionary<IRetainAssetKey, AsyncOperationHandle> _retainedAssets;
public AddressablesAssetService()
{
_retainedAssets = new Dictionary<IRetainAssetKey, AsyncOperationHandle>();
}
public IRetainAssetKey GetAssetKeyByPath(string path)
{
var fullPath = $"Assets/Resources_moved/{path}.prefab";
var referenceId = AssetDatabase.AssetPathToGUID(fullPath);
var reference = new AssetReference(referenceId);
return new AddressableAssetKey(reference);
}
public UniTask<T> Retain<T>(IRetainAssetKey retainedAssetKey)
{
var addressableReference = (AssetReference)retainedAssetKey.Reference;
var retainedAssetHandle = addressableReference.LoadAssetAsync<T>();
_retainedAssets[retainedAssetKey] = retainedAssetHandle;
return retainedAssetHandle.ToUniTask();
}
public void Release(IRetainAssetKey releasedAssetKey)
{
if (!_retainedAssets.TryGetValue(releasedAssetKey, out var handle))
return;
var addressableReference = (AssetReference)releasedAssetKey.Reference;
var guidToAssetPath = AssetDatabase.GUIDToAssetPath(addressableReference.AssetGUID);
var key = guidToAssetPath.Replace(@"Assets/Resources_moved/", "").Replace(".prefab", "");
Addressables.GetDownloadSizeAsync(key).Completed += (r) =>
{
Debug.LogError("before " + key + " " + r.Result + " " + r.IsDone);
};
// remove from manager
_retainedAssets.Remove(releasedAssetKey);
// method 1
//addressableReference.ReleaseAsset();
// method 2
Addressables.Release(handle);
Debug.LogError($"Releasted {key}");
Addressables.GetDownloadSizeAsync(key).Completed += (r) =>
{
Debug.LogError("after " + key + " " + r.Result + " " + r.IsDone);
};
}
}
Any help would be appreciated!
Thanks
An update about new findings: 1. AssetDatabase is part of UnityEngine.Editor, a mistake on my part which I missed (using Resharper for imports) 2. Found the guide below (link at the bottom), which lead me to find that my groups were indeed packed together - thus possibly not being released
Will update once I resolve the 1st points
