Baldur's Gate 3 Script Extender vs ScriptHookVDotNet

Baldur's Gate 3 Script Extender adds Lua and Osiris scripting support for mods in Baldur's Gate 3. A mod can enable Lua with a feature flag and load bootstrap scripts for the client and server. The extender keeps separate Lua states for the game server and each client, and its console can run Lua code and registered console commands. Configuration options provide Lua and Osiris debugger interfaces with configurable listening ports, and logging options can write Osiris activity, runtime output, story compilation and compilation errors to files. An EnableAchievements option can re-enable achievements in modded games. SendCrashReports defaults to true and uploads minidumps to a crash report collection server after a crash. Installation involves extracting DWrite.dll into the game's bin directory. The extender updates when the game launches by downloading and applying an update. It supports Windows and Linux via Proton, but does not run on game versions older than patch 5; new versions target the latest game version. It is free to obtain under a license that includes the MIT License and a Commons Clause restriction on selling the software or substantially derived products and services.

ScriptHookVDotNet is free Windows PC script runtime software for Grand Theft Auto V Story Mode. It runs under Script Hook V and connects custom .NET code to the game, allowing scripts in any .NET language; the FAQ recommends C# for new coders. Object-oriented APIs provide guided interfaces and documentation for common GTA V scripting tasks. Scripts are built as .NET Framework class libraries and can reference the ScriptHookVDotNet3 package, including through NuGet, as well as arbitrary .NET Framework libraries. The runtime and scripts can be reloaded with SHVDN commands, although the runtime cannot currently reload after Script Hook V unloads all loaded ASI scripts. The project says official game versions are supported, while some advanced scripts may fail on certain versions. Requirements include Script Hook V, Microsoft .NET Framework 4.8 or later, and the x64 Microsoft Visual C++ Redistributable for Visual Studio 2019 or later. GTA Online requires removing SHVDN and related mods when an ASI loader is installed.
