Defining new resources at runtime

Unity Engine

Anyone have tips on creating a new Catalog or IResourceLocation programatically at run time?

I’ve a large number of assets on a server with naming conventions.
I’d like to use Addressables for it’s load, instantiate, cache, counter, and memory-management.

Options I was thinking…

  1. Craft an IResourceLocator and add to existing ResourceLocationMap at runtime?

  2. Craft a catalog and use LoadContentCatalog.
    Catalog is just an asset- How to create them?
    Reverse engineer from Editor GUI or build scripts?

Would either of these approaches be appropriate? TIA

If you have a large number of assets, set them up in packs using addressables and selectively load the assets you need.
Loading the catalog doesn’t load the assets. Catalog is just a json file containing the asset keys and the path to the actual bundles, plus some base64 encoded stuff.

Do you really need to create a catalog at runtime? The only case I can think of needing any kind of catalog creation, would be if you created bundles at runtime, which isn’t possible as far as I know.

I would go with a ResourceLocator, you can either use a ResourceLocationMap or create your own.
e.g. using an ResourceLocationMap

public void AddResourceLocations()
{
  List<ResourceLocationData> locationData = new List<ResourceLocationData>();

  locationData.Add(new ResourceLocationData(new string[] {"key"},   "c:/path/to/asset_bundle.asset", typeof(AssetBundleProvider), typeof(AssetBundle)});

  var locMap = new ResourceLocationMap(locationData);
  Addressables.ResourceLocators.Add(locMap);
}
