Unified API

About

Unified API is a simple, general purpose API to aid in multiloader development. The API achieves this through:

• unified, cross-loader registries
• various helpers to allow access to features such as loot table or creative inventory injection
• platform-agnostic events, so that mods can implement custom behaviour in common code
• useful utilities such as new components or tags
• convenient registry builders to automate the creation of woodsets, armor, tools and more
• all registered content goes through the convenient supplied class

The Getting Started page will guide you through creating a multiloader project with Unified API.

API Stability

Unified API is split into api. and impl. packages. Unified API avoids making breaking changes to the api unless between breaking Minecraft releases, to ensure that all mods made for a specific version will always work on that version (similarly to Fabric API). If a method or class is marked as deprecated, it will only be removed in the next vanilla version port.

When breaking changes are made (such as from 26.1.x -> 26.2) those changes will be covered in the migration guide.

Versions

Unified API is designed for both Fabric & NeoForge.

The following Minecraft versions are currently supported:

• 26.2
• 26.1.2
• 26.1.1
• 26.1
