BeatSaber-IPA-Reloaded is a mod loader for the Unity game Beat Saber. It injects into the game process via a native DLL proxy (Doorstop) that hooks winhttp.dll during Unity's startup to load a managed injector assembly. The injector bootstraps the loader, which discovers and manages plugins, handles dependency resolution, configuration, logging, and anti-malware scanning. The repository comprises several assembly projects: a native proxy (C++), a managed injector (C#), the loader itself, a command-line patcher/installer, and a meta-project that assembles the final output. The loader features an advanced configuration system that uses System.Reflection.Emit to dynamically generate type-safe config stores with automatic serialization, change tracking, and thread-safe locking. Plugin dependencies are resolved via topological sorting with cycle detection and conflict handling. The logging subsystem supports pluggable printers for console, file, and compressed output. The code demonstrates high craftsmanship in IL emit code generation, dependency graph algorithms, and fast reflection accessors. However, some parts show age (deprecated thread abort calls, obsolete plugin interfaces) and tight coupling between assemblies via InternalsVisibleTo attributes. Overall, it is a solid mod loader with several reusable components.
The LLM identified 3 files worth highlighting for reuse:
Generates dynamic config store types using System.Reflection.Emit. This component creates a wrapper around a user-defined config class that implements IConfigStore, INotifyPropertyChanged, and adds serialization, change tracking, and thread-safe locking. It is self-contained (depends only on reflection emit and a few interfaces) and could be extracted into a reusable library for auto-generating persistent, observable config objects from plain C# classes.
Implements the core plugin loading and dependency resolution algorithm. The DoOrderResolution method performs a topological sort on plugin dependencies, detects cycles, resolves conflicts, and propagates disabled/ignored states. While coupled to the loader's metadata types, the algorithm itself can be abstracted into a general-purpose dependency graph resolver suitable for other plugin systems or service containers.
Provides FieldAccessor, PropertyAccessor, and MethodAccessor using System.Reflection.Emit dynamic methods to achieve fast reflection. This component is isolated, reusable, and solves a common performance problem in .NET when reflection is needed frequently. It can be extracted into a standalone utility library.
