Starward is a third-party Windows desktop companion and launcher for HoYoverse games (Genshin Impact, Honkai: Star Rail, Honkai Impact 3rd, Zenless Zone Zero). It replaces the official HoYoPlay with enhanced features: game installation and update management (including pre-download and delta patching), gacha (wish) history tracking with UIGF import/export, real-time game record display (Spiral Abyss, Simulated Universe, etc.), HDR screenshot capture and batch conversion, playtime statistics, game account switching, and cloud game launching. The application is built with .NET 10 (C#), WinUI 3, and MVVM (CommunityToolkit.Mvvm), with a separate gRPC-based background service (Starward.RPC) for privileged game installation tasks. It uses SQLite via Dapper for local data storage, WebView2 for miHoYo login and game notices, and integrates with miHoYo/HoYoverse APIs via reverse-engineered clients. The codebase is well-structured into Core, RPC, Setup, and UI projects, with strong localization support (10+ languages via Crowdin). It demonstrates advanced Windows development skills including Win32 interop, Win2D image processing, and custom XAML controls. However, it is Windows-only, tightly coupled to miHoYo's volatile APIs, and contains some code duplication (e.g., DriveHelper) and hardcoded registry paths.
This repository is a developer toolchain for creating custom node graph logic in Genshin Impact's UGC mode (Miliastra Wonderland). It compiles a subset of TypeScript into a binary GIA format (protobuf) and injects it into game map files (.gil). The system includes a CLI (gsts) for build/inject/watch, a multi-stage compiler (TS → GS intermediate → IR JSON → GIA), an injector that patches save files, and a comprehensive set of custom ESLint rules enforcing the supported TypeScript subset. It supports both server-side and client-side node graphs with two modes (classic and beyond), and provides extensive type definitions, bilingual support (Chinese/English), and auto-generated tests covering thousands of node combinations. The codebase demonstrates strong engineering practices: rigorous testing, type safety, i18n, and modular architecture. However, it depends heavily on reverse-engineered game data (node IDs, pin records, protobuf schemas) that must be updated with each game patch, and some components are tightly coupled to internal definitions.
GrasscutterCommandGenerator is a Windows Forms (.NET Framework 4.8) desktop application that serves as a comprehensive administration and command-generation tool for Grasscutter, a Genshin Impact private server emulator. It provides a GUI to generate and execute server commands (e.g., give items, teleport, spawn entities, set weather), edit server configuration files (gacha banners, drops, shops, activities), manage player accounts and permissions, and run a MITM proxy to intercept game traffic. The application is heavily data-driven, relying on embedded localized text files for game entity IDs and names, and uses Newtonsoft.Json for serialization. It supports multi-language UI (Chinese, English, Russian, Traditional Chinese) and integrates with a remote command plugin (gc-opencommand-plugin) for direct server interaction. The architecture is a monolith WinForms application with a tabbed page interface. The main entry point is Program.cs, which initializes the main form (FormMain) that hosts multiple pages (e.g., PageGiveItem, PageAvatar, PageQuest, PageProxy) and modal editors (FormGachaBannerEditor, FormShopEditor). A base class (BasePage) provides common lifecycle and command execution methods. The application communicates with the Grasscutter server via HTTP (OpenCommandAPI) and can also modify system proxy settings to redirect game traffic. External dependencies include the .NET Framework, Newtonsoft.Json (embedded), and Windows API calls for proxy and hotkey management. Key data flows involve loading game data from embedded resource files at startup, constructing command strings from user input, and optionally sending them to the server. The proxy module (Eavesdrop) captures and forwards HTTP/HTTPS traffic between the game client and server. The tool also supports importing/exporting player data in the GOOD (Genshin Open Object Description) format. While the codebase is functional and well-organized for its domain, it is tightly coupled to the Grasscutter server API and game data, requiring manual updates with each game patch. No automated tests are present, and the reliance on hardcoded data and Windows-specific features limits portability.
