Resolved Is it possible to retrieve a guid from the Catalog at runtime?

    By default the guids of the addressable files are included in the catalog. But is there a way to retrieve it?
    For example, if I have a texture on the address "myTexture", is there a way to get the guid of that texture?

    Code (CSharp):
    1. AddressableAssetSettings settings = AddressableAssetSettingsDefaultObject.Settings;
    2. List<AddressableAssetEntry> allEntries = new List<AddressableAssetEntry>(settings.groups.SelectMany(g => g.entries));
    That allEntries has the address and guid but can only be accessed in editor. Any way to access the guids in the catalog during runtime?

    Hi @Laiken it's a little tricky to do at runtime. You can use Addressables.ResourceLocators to retrieve a mapping of all keys to their resource locations, but keys could refer to a guid, address, or label. So what you can do is reverse the elements of the dictionary. The guid associated with a particular address will reference the same location.

    Code (CSharp):
    1.  
    2. Addressables.InitializeAsync().WaitForCompletion(); // populate ResourceLocators
    3. var locToKeys = new Dictionary<string, List<object>>();
    4. foreach (IResourceLocator locator in Addressables.ResourceLocators)
    5. {
    6.     ResourceLocationMap map = locator as ResourceLocationMap;
    7.     if (map == null)
    8.         continue;
    9.     foreach (KeyValuePair<object, IList<IResourceLocation>> keyToLocs in map.Locations)
    10.     {
    11.         foreach (IResourceLocation loc in keyToLocs.Value)
    12.         {
    13.             if (!locToKeys.ContainsKey(loc.InternalId))
    14.                 locToKeys.Add(loc.InternalId, new List<object>(){ keyToLocs.Key });
    15.             else
    16.                 locToKeys[loc.InternalId].Add(keyToLocs.Key);
    17.         }
    18.     }
    19. }
    20.
