Func<IResourceLocation, string>	A function taking an IResourceLocation and returning a transformed string location.

참고

Used to assign a function to the ResourceManager that replaces location identifiers used at runtime. This is useful when you want to load assets from a different location than the one specified in the content catalog, for example downloading a remote AssetBundle from a different URL.

Assigning this value through the Addressables object will set the value on the ResourceManager.

The example below instantiates a GameObject from a local AssetBundle. The location identifier of the bundle is replaced with a file URI, and so the bundle is loaded via UnityWebRequest.

public AssetReferenceGameObject asset; // Identify the asset
AsyncOperationHandle<GameObject> opHandle;

void UsingInternalIdTransformFuncSample()
{
    Addressables.InternalIdTransformFunc = MyCustomTransform;
    opHandle = Addressables.InstantiateAsync(asset);
    opHandle.Completed += OnInstantiateComplete;
}

//Implement a method to transform the internal ids of locations
static string MyCustomTransform(IResourceLocation location)
{
    if (location.ResourceType == typeof(IAssetBundleResource)
        && !location.InternalId.StartsWith("http"))
    {
        Debug.Log($"Replace local identifier with remote URL : {location.InternalId}");
        return "file:///" + location.InternalId;
    }

    return location.InternalId;
}

void OnInstantiateComplete(AsyncOperationHandle<GameObject> handle)
{
    if (handle.Status == AsyncOperationStatus.Succeeded)
    {
        Debug.Log($"Successfully instantiated GameObject named '{handle.Result.name}'");
    }
}

void ReleaseResources()
{
    Addressables.Release(opHandle);
}

// When ready to release the asset, call ReleaseResources().
// For example during OnDestroy().
//void OnDestroy()
//{
//    ReleaseResources();
//}
