GameCollector.StoreHandlers.WargamingNet 4.2.0.5

GameCollector

a fork of GameFinder

.NET library for finding games. GameCollector expands on upstream GameFinder (which is primarily designed to support modding tools), by adding additional supported store launchers, emulators, and data sources, and includes additional information about each game (sufficient for a multi-store game launcher such as GLC). The following launchers and emulators are supported:

handler	package
Amazon Games
Arc
Bethesda.net
Big Fish Game Manager
Blizzard Battle.net
Dolphin Emulator
EA app
Epic Games Store
Game Jolt Client
GOG Galaxy
Humble App
Indiegala IGClient
itch
Legacy Games Launcher
Multiple Arcade Machine Emulator (MAME)
Oculus
Origin
Paradox Launcher
Plarium Play
Riot Client
RobotCache Client
Rockstar Games Launcher
Steam
Ubisoft Connect
Wargaming.net Game Center
Xbox Game Pass

If you are interested in understanding how GameCollector/GameFinder finds these games, check the upstream wiki for more information.

Additionally, the following Linux tools are supported:

Wine

Example

The example project uses every available store handler and can be used as a reference. You can go to the GitHub Actions Page and click on one of the latest CI workflow runs to download a build of this project.

Usage

All store handlers inherit from AHandler<TGame, TId> and implement FindAllGames() which returns IEnumerable<OneOf<TGame, ErrorMessage>>. The OneOf struct is a F# style union and is guaranteed to only contain one of the following: a TGame or an ErrorMessage. I recommended checking out the OneOf library, if you want to learn more.

Some important things to remember:

• All store handler methods are pure, meaning they do not change the internal state of the store handler because they don't have any. This also means that the results are not cached and you shouldn't call the same method multiple times. It's up to the library consumer to cache the results somewhere.
• Ids are store dependent. Each store handler has their own type of id and figuring out the right id for your game might require some testing. You can find useful resources in this README for some store handlers.

Basic Usage

var results = handler.FindAllGames();

foreach (var result in results)
{
    // using the switch method
    result.Switch(game =>
    {
        Console.WriteLine($"Found {game}");
    }, error =>
    {
        Console.WriteLine(error);
    });

    // using the provided extension functions
    if (result.TryGetGame(out var game))
    {
        Console.WriteLine($"Found {game}");
    } else
    {
        Console.WriteLine(result.AsError());
    }
}

Finding a single game

If you're working on an application that only needs to find 1 game, then you can use the FindOneGameById method instead. IMPORTANT NOTE: the results are not cached. If you call this method multiple, the store handler will do the same thing multiple times, which is search for every game installed. Do not call this method if you need to find multiple games.

var game = handler.FindOneGameById(someId, out var errors);

// I highly recommend logging errors regardless of whether or not the game was found.
foreach (var error in errors)
{
    Console.WriteLine(error);
}

if (game is null)
{
    Console.WriteLine("Unable to find game");
} else
{
    Console.WriteLine($"Found {game}");
}

Finding multiple games

If you need to find multiple games at once, you can use the FindAllGamesById method instead. This returns an IReadOnlyDictionary<TId, TGame> which you can use to lookup games by id. IMPORTANT NOTE: the results are not cached. You have to do that yourself.

var games = handler.FindAllGamesById(out var errors);

// I highly recommend always logging errors.
foreach (var error in errors)
{
    Console.WriteLine(error);
}

if (games.TryGetValue(someId, out var game))
{
    Console.WriteLine($"Found {game}");
} else
{
    Console.WriteLine($"Unable to find game with the id {someId}");
}

GameCollector Special Notes

General

• Known issues: See GameCollector issues here or upstream GameFinder issues here. Please do not submit bugs/requests for GameCollector on GameFinder's GitHub.
• DLCs/clones: When an entry is detected as a DLC addon (or a clone in the MAME handler), the BaseGame field is set to the ID of the main game (or sometimes "False" when it can't be determined). To hide DLCs from the consumer application, use FindAllGames(baseOnly: true), or do not use entries with a non-null BaseGame.
• Owned not-installed games: Some handlers can find owned not-installed games. To support this feature for Steam games, see note below. To show only installed games, use FindAllGames(installedOnly: true), or do not use entries where IsInstalled is False.

Dolphin/MAME

These handlers both require you pass the path to the emulator executable.

Oculus

If the Oculus service is running (as it does even when the program is not open), the database is usually locked and connot be read. The handler attempts to stop the service, but this only works if the consumer application is running as administrator.

Upstream Supported Launchers

The following handlers come from upstream GameFinder:

Steam

Steam is supported natively on Windows and Linux. Use SteamDB to find the ID of a game.

Usage (cross-platform):

var handler = new SteamHandler(FileSystem.Shared, OperatingSystem.IsWindows() ? WindowsRegistry.Shared : null);

GameCollector adds the ability to check a Steam profile for owned not-installed games. A specific Steam ID may be specified, though it will automatically attempt to find one. However, this feature requires that an API key be activated and specified, and the user profile set to public.

GOG Galaxy

GOG Galaxy is supported natively on Windows, and with Wine on Linux. Use the GOG Database to find the ID of a game.

Usage (native on Windows):

var handler = new GOGHandler(WindowsRegistry.Shared, FileSystem.Shared);

Usage (Wine on Linux):

See Wine for more information.

// requires a valid prefix
var wineFileSystem = winePrefix.CreateOverlayFileSystem(FileSystem.Shared);
var wineRegistry = winePrefix.CreateRegistry(FileSystem.Shared);

var handler = new GOGHandler(wineRegistry, wineFileSystem);

GameCollector adds finding owned not-installed GOG games.

Epic Games Store

The Epic Games Store is supported natively on Windows, and with Wine on Linux. Use the Epic Games Store Database to find the ID of a game (WIP).

Usage (native on Windows):

var handler = new EGSHandler(WindowsRegistry.Shared, FileSystem.Shared);

Usage (Wine on Linux):

See Wine for more information.

// requires a valid prefix
var wineFileSystem = winePrefix.CreateOverlayFileSystem(FileSystem.Shared);
var wineRegistry = winePrefix.CreateRegistry(FileSystem.Shared);

var handler = new EGSHandler(wineRegistry, wineFileSystem);

GameCollector adds finding owned not-installed EGS games.

Origin

Origin is supported natively on Windows, and with Wine on Linux. Note: EA is deprecating Origin and will replace it with EA app.

Usage (native on Windows):

var handler = new OriginHandler(FileSystem.Shared);

Usage (Wine on Linux):

See Wine for more information.

// requires a valid prefix
var wineFileSystem = winePrefix.CreateOverlayFileSystem(FileSystem.Shared);

var handler = new OriginHandler(wineFileSystem);

EA app

The EA app is the replacement for Origin on Windows: See EA is deprecating Origin. This is by far the most complicated Store Handler. You should read the upstream wiki entry. This implementation decrypts the encrypted file created by the EA app. You should be aware that the key used to encrypt the file is derived from hardware information. If the user changes their hardware, the decryption process might fail because they key has changed.

The EA app is only supported on Windows.

Usage:

var handler = new EADesktopHandler(FileSystem.Shared, new HardwareInfoProvider());

Xbox Game Pass

This package used to be deprecated, but support was re-added in GameFinder 3.0.0. Xbox Game Pass used to install games inside a SYSTEM protected folder, making modding not feasible for the average user. You can read more about this here.

Xbox Game Pass is only supported on Windows.

Usage:

var handler = new XboxHandler(FileSystem.Shared);

Bethesda.net

As of May 11, 2022, the Bethesda.net launcher is no longer in use. The upstream package GameFinder.StoreHandlers.BethNet has been deprecated and marked as legacy.

Wine

Wine is a compatibility layer capable of running Windows applications on Linux. Wine uses prefixes to create and store virtual C: drives. A user can install and run Windows program inside these prefixes, and applications running inside the prefixes likely won't even notice they are not actually running on Windows.

Since GameCollector/GameFinder is all about finding games, it also has to be able to find games inside Wine prefixes to provide good Linux support. The package NexusMods.Paths from NexusMods.App provides a file system abstraction IFileSystem which enables path re-mappings:

AWinePrefix prefix = //...

// creates a new IFileSystem, with path mappings into the wine prefix
IFileSystem wineFileSystem = prefix.CreateOverlayFileSystem(FileSystem.Shared);

// this wineFileSystem can be used instead of FileSystem.Shared:
var handler = new OriginHandler(wineFileSystem);

// you can also create a new IRegistry:
IRegistry wineRegistry = prefix.CreateRegistry(FileSystem.Shared);

// and use both:
var handler = new EGSHandler(wineRegistry, wineFileSystem);

Default Prefix Manager

GameCollector.Wine implements a IWinePrefixManager for finding Wine prefixes.

Usage:

var prefixManager = new DefaultWinePrefixManager(FileSystem.Shared);

foreach (var result in prefixManager.FindPrefixes())
{
    result.Switch(prefix =>
    {
        Console.WriteLine($"Found wine prefix at {prefix.ConfigurationDirectory}");
    }, error =>
    {
        Console.WriteLine(error.Value);
    });
}

Bottles

GameCollector.Wine implements a IWinePrefixManager for finding Wine prefixes managed by Bottles.

Usage:

var prefixManager = new BottlesWinePrefixManager(FileSystem.Shared);

foreach (var result in prefixManager.FindPrefixes())
{
    result.Switch(prefix =>
    {
        Console.WriteLine($"Found wine prefix at {prefix.ConfigurationDirectory}");
    }, error =>
    {
        Console.WriteLine(error.Value);
    });
}

Proton

Valve's Proton is a compatibility tool for Steam and is mostly based on Wine. The Wine prefixes managed by Proton are in the compatdata directory of the steam library where the game itself is installed. Since the path is relative to the game itself and requires the app id, erri120 decided to put this functionality in the Steam store handler:

SteamGame? steamGame = steamHandler.FindOneGameById(1237970, out var errors);
if (steamGame is null) return;

ProtonWinePrefix protonPrefix = steamGame.GetProtonPrefix();
var protonPrefixDirectory = protonPrefix.ProtonDirectory;

if (protonDirectory != default && fileSystem.DirectoryExists(protonDirectory))
{
    Console.WriteLine($"Proton prefix is at {protonDirectory}");
}

Trimming

Self-contained deployments and executables can be trimmed starting with .NET 6. This feature is only available to applications that are published self-contained.

Trimmable:

• GameCollector.Common
• GameCollector.RegistryUtils
• GameCollector.Wine
• GameCollector.StoreHandlers.Steam
• GameCollector.StoreHandlers.GOG
• GameCollector.StoreHandlers.EGS
• GameCollector.StoreHandlers.Origin

NOT Trimmable:

• GameCollector.StoreHandlers.EADesktop: This package references System.Management, which is not trimmable due to COM interop issues. See dotnet/runtime#78038, dotnet/runtime#75176 and dotnet/runtime#61960 for more details.

I recommend looking at the project file of the example project, if you run into warnings or errors with trimming.
