📜 Almanac Core
Content-as-data library for the Majestic ecosystem: datapack-driven spells, rituals, research nodes and relics. Adds no content on its own.
✨ Overview
|
Almanac Core lets magic content be defined as datapack JSON instead of Java code. It parses spell, ritual, research-node and relic definitions from any datapack, keeps them in a shared registry, and syncs them to connected clients — ready for other mods (or third-party datapacks) to reference. If you were told to install this mod, it's because another mod on your instance depends on it — most likely Majestic. On its own it adds no items, blocks or gameplay. |

🎯 Features
📝 Data-Driven Definitions
Full Codec-based schemas for spells (school, tier, cost, cast type, effects), rituals (altar tier, item/tag inputs, essence cost, risk, outputs), research nodes (prerequisites, unlocks, tree position) and relics (slot, passives, active ability, set) — all plain JSON, reloadable without a restart.
🔄 Reload-Safe Loaders
Each kind is parsed by its own datapack reload listener into an in-memory registry, so a bad file in one category never wipes the others, and content updates apply on /reload.
🔌 Client Sync
The full loaded content set is pushed to every connected client on login and on every datapack reload, so client-side systems (a future guide, JEI, HUDs) always see the current state.
🔍 JEI-Ready
Built to plug into JEI once wired — ritual and research categories are designed around the same data this library already loads.
🧱 Mod Structure
| Package | What it provides |
|---|---|
codec | The SpellDefinition / RitualDefinition / ResearchNodeDefinition / RelicDefinition schemas. |
data | The reload listeners and the shared in-memory content registry. |
net | Server→client sync of the loaded content. |
jei / guide | Future integration points (JEI categories, an in-game guide bridge) — not wired yet. |
📋 Requirements
| Minecraft | 1.21.1 |
| NeoForge | 21.1.249+ |
| Java | 21 |
| Side | Client and Server (required on both) |
| Depends on | Astral Core |
| Optional | JEI |
🎮 How to Use
- Install as a dependency of another mod that requires it (e.g. Majestic), on both client and server.
- Install Astral Core alongside it.
- Drop spell/ritual/research-node/relic JSON in a datapack under
data/<namespace>/almanac/<kind>/— it loads automatically.
Early development. Almanac Core is still pre-release (0.0.0-beta.x); JSON schemas may change between betas.
