Hilt
Hilt is a shared library for NeoForge, maintained within the Modern Mods project, that supplies common code for other mods to build on.
What it does
Hilt functions as a library for other mod developers, so it introduces no items, blocks or gameplay mechanics for players to use directly. It provides reusable infrastructure: registries for content registration, data-driven content, material systems, recipe serialization, menus and screens, fluid-related systems and tags for resource handling. Larger NeoForge mods can depend on it instead of carrying duplicate copies of the same functionality.
The project brings over pieces of the design and code history traced back to Mantle and related Slime Knights work, reworked for current NeoForge. Its stated goal is a stable shared foundation that does not pull unrelated gameplay systems in with it. Individual releases require a particular NeoForge build, and the metadata included with each release lists the requirements for any mod that depends on Hilt.
Hilt is released under the MIT License as open source, and it belongs to the wider Modern Mods family, whose NeoForge projects span crafting, automation, progression and exploration. Its source code and issue tracker are publicly linked. A server running it needs every connecting player to have it too.
Key features
Registries and content registration
Hilt supplies registry utilities for registering content that dependent mods add to the game.
Data-driven content
Content can be defined through data rather than code, using the library's data systems.
Materials and recipes
Shared material handling and recipe serialization are provided so dependent mods do not rebuild them.
Menus, screens and fluids
Menu and screen helpers and fluid-related systems are included for mods that add interfaces or fluid content.
Tags and resource handling
Tag support and resource handling are part of the shared foundation for larger mod projects.
Compatibility
Latest build for each game version and loader.

Use cases
Who it’s for: Mod developers building NeoForge projects, and server owners whose installed mods list Hilt as a dependency. Players who only want gameplay content will not need to use it directly.
