Description
📖 SLM: Codex
This mod introduces a Codex system that enhances how items are displayed and understood, providing detailed and organized information directly in-game.
It supports Items, Weapons, Armor, and Curios.
⚙️ Features
Each supported item can include a complete Codex entry with:
- 🧩 Passives
- ⚔️ Skills
- 📜 Description / Lore
- 📊 Attributes / Stats
All information is presented through a clean, tab-based interface.
🗂️ Supported Categories
The Codex system is divided into multiple sections:
- 🗡️ Weapons

- 🛡️ Armor

- 🎒 Curios

- 📦 Items
Each category has its own specialized layout and data handling.
🧠 Skill Integration
- Supports Innate Skills integration
- Can display and redirect skills from compatible systems (such as Epic Fight)
- Provides a unified view of abilities tied to equipment
📘 Codex JSON Guide
The Codex system allows you to define custom entries for items, weapons, armor, and curios using JSON.
You can use translation keys or raw text for any visible field:
- Translation keys enable multi-language support
- Raw text is useful for quick definitions or testing
🧩 Common Fields (All Entries)
Field Description nameKey Item name. Supports translation keys or plain text. nameColorKey Adding a color to the item name supports standard Minecraft styles and hexadecimal as a string. descriptionKey Main description shown in the codex. overwritteTooltip If true, replaces the default tooltip with the codex one. passiveSkills List of passive abilities. activeSkills List of active abilities.
The entries for Passive Skills or Active Skills are not mandatory; if you don't include them or leave them blank, they won't appear in the codex! And your file will still work.
⚙️ Skills Format (Passive & Active)
Both passiveSkills and activeSkills use the same structure (Supports multiple entries):
