OS Cobblemon Library

OS Cobblemon Library is a lightweight shared Cobblemon API and compatibility library for Fabric and NeoForge.

It provides reusable helpers for common Cobblemon systems, reducing duplicated code and giving mods a consistent integration layer across supported loaders.

Features

The library provides utilities and APIs for:

• Pokémon identity and matching
• Species and Pokémon creation
• Pokémon properties and labels
• IVs, abilities and types
• Party and PC storage access
• Pokémon entity identity, ownership and state
• Pokémon size utilities
• Battle inspection
• Cobblemon events
• Pokédex queries

The API is designed around reusable abstractions so mods can share the same implementation across supported loaders whenever possible.

Compatibility

• Minecraft: 1.21.1
• Cobblemon: 1.8.1 to <1.9.0
• Fabric
• NeoForge
• Java: 21

For Players

OS Cobblemon Library is primarily a dependency library.

It does not add standalone gameplay content by itself.

Install it when another mod lists OS Cobblemon Library as a required dependency.

Make sure to download the file matching your mod loader.

For Developers

OS Cobblemon Library centralizes common Cobblemon integrations behind a shared API.

This helps projects:

• Reduce duplicated Cobblemon integration code
• Share logic between Fabric and NeoForge
• Keep compatibility code centralized
• Make future Cobblemon updates easier to maintain

The project includes documentation covering the public API, common integration patterns, local development usage and compatibility guidelines.
