OS Cobblemon Library Mod (1.21.1) – Run Cobblemon Addons Across Both Fabric

OS Cobblemon Library Mod provides a shared API and compatibility layer for Cobblemon. This mod connects Pokémon data, storage, battles, events, and Pokédex tracking under one unified system. Because of this setup, other addons can share the same code across both Fabric and NeoForge without duplicating their work. It works strictly as a required background tool for other mods and does not add any standalone gameplay content on its own.

Features:

• Shared Codebase: Lets addon projects run the same Cobblemon code on both Fabric and NeoForge.
• Pokémon Data Tools: Tracks Pokémon identity, forms, aspects, marks, sizes, abilities, and IV stats.
• Storage Access: Reads and searches player Party slots and PC storage boxes using UUIDs or custom rules.
• Battle Inspector: Checks details on wild, trainer, and PvP battles, including active actors, fainted Pokémon, and winners.
• Event Hooks: Tracks in-game actions like captures, evolutions, hatching, trading, healing, and level changes.
• Pokédex Queries: Checks player progress on seen and caught species, forms, aspects, and shiny knowledge.
• Spawns and creates Pokémon directly on the server without using chat commands.
• Saves custom mod data directly to a Pokémon using namespaced keys.
• Checks Pokémon mob states in the world, including ownership, evolution status, and whether they are busy or in a battle.
• Groups multiple event subscriptions together so they can be turned off cleanly at the same time.

API Domains:

• pokemon: Handles identity, matching, creation, persistent data, IVs, abilities, types, labels, and size.
• entity: Checks Pokémon mob identity, ownership, and world state.
• storage: Manages Party and PC access, lookup, matching, and counts.
• event: Controls reusable Cobblemon event subscriptions and lifecycle handling.
• battle: Runs battle inspection and classification.
• pokedex: Performs species, form, variation, and completion queries.
