About

CobbleBrain is a mod that gives Pokémon a “brain,” allowing them to think, talk, and interact dynamically with the world. It integrates artificial intelligence into gameplay, making your companions talk to you, react to battles, protect you from mobs and even cook a delicious steak, all of that using your prompt.

Wild Pokémon can also interact with the player and the world, creating quests, remembering your actions, and reacting to how you treat their species.

With the built-in Visual Story Creator, players can make custom interactive quests, branching RPG campaigns, minigames and more!

You can also fully customize each Pokémon's personality through the built-in Personality Editor, allowing every companion to develop a unique identity.

Features

• Pokémon can talk to the player and to each other autonomously.
• Speech-to-Text (Voice Input): Talk and give commands to Pokémon directly using your microphone (requires MCMti).
• Pokémon can perform actions such as attacking, building, excavating, cooking, repairing tools, growing plants, and more.
• Per-Action Customization: Toggle each action individually and customize cooldowns to balance gameplay.
• Dialogue influenced by friendship, nature, past interactions, and world conditions.
• Memory system that stores previous interactions.
• Wild Pokémon quests and karma system that react to your actions.
• Raid events triggered when Pokémon species become hostile toward you.
• Fully configurable AI prompts, gameplay settings, and behaviors through the Mod Menu configuration screen.
• Supports cloud AI models (Google AI Studio, OpenAI, OpenRouter, Player2), local models via LM Studio and Player2 and Offline gameplay.
• Multiplayer compatible, with each player managing their own AI processing.
• Pokémon Personality Editor for customizing Traits, Quirks, Likes, Dislikes, and other personality attributes.

Visual Story Creator (Alpha)

The Story creator is an in-game editor with visual scripting (blocks) to build campaigns, quests and minigames integrated with Cobblemon.

The goal is to let any player create Pokémon stories/fan-games in a simple, familiar environment. The system also supports emergent AI narratives to generate dynamic lines and progression while keeping full script and direction control in your hands (AI usage is completely OPTIONAL, the editor works perfectly fine without AI features).

Access the editor in-game on the mod menu.

You can easily export your Project in-menu, just click in File, export ZIP, select the location you want to export and done, your Project will be zipped and ready to publish! For others to play your story, they would just have to take your project, put it in the cobblebrain/storypacks folder, go to 'Play story' and done!

⚠️ IMPORTANT NOTICE (ALPHA)

Quests

Wild Pokémon may approach you and start small quests, such as:

• Item Requests – bring a specific item to the Pokémon.
• Advice Requests – answer questions and influence your reputation.
• Battle Requests – defeat a specific Pokémon in battle.
• Lost Item Requests – find a treasure barrel with the help of the quest tracker

Completing quests may reward the player with items or gifts.

Karma System

Each Pokémon species tracks your behavior.

• Killing Pokémon or failing quests lowers karma.
• Helping Pokémon increases karma.

Karma influences how Pokémon react to you in future interactions.
To disable the karma system, go to the mod settings and turn off enable karma.

Raids

If your karma with a species becomes lower than -8, that species may organize a raid.
A raid spawns multiple Pokémon that will attempt to defeat the player.

Worse karma = stronger raids.
To disable raids, go to the mod settings and turn off schedule raids.

How to Play

You can choose to play using cloud models, local models, or completely offline.

A. Cloud Mode (Recommended)

Cloud mode uses external AI providers to process dialogue.

1. Player2 App (Recommended)

• Install the Player2 app and create an account.
• Run Player2.exe (the app)

Player2 includes a free amount of energy, which can be replenished daily using a spinner. You can also choose the AI model that best fits your needs. In general, more expensive models are smarter.

Here is a YouTube tutorial!

2. Other Providers (Google AI Studio, OpenAI, OpenRouter, etc.)

1. Create an account with the provider.
2. Generate an API key from the provider’s dashboard.
3. Choose a model (examples: gemma-3-12b-it, gpt-4.1-mini, anthropic/claude-3.5-sonnet).
4. Open the mod config Menu and fill:
   • apiKey: your generated key
   • apiBaseUrl: provider’s official URL
   • aiModel: ID of the chosen model

Here is a YouTube tutorial!

B. Local Mode

Local mode runs AI models directly on your computer using LM Studio or Player2.
WARNING: LOCAL MODELS MAY CAUSE PROBLEMS IF YOU RUN/INSTALL MODELS THAT ARE TOO HEAVY.

Steps:

1. Install LM Studio (available for Windows, Mac, Linux).
2. Open LM Studio and set up a folder for storing models.
3. Download a model (examples: LLaMA, Mistral).
   
   • 4b–5b models → lightweight, fast, good for simple dialogues.
   • 7b–8b models → balanced, deeper responses.
   • 12b+ models → complex, detailed dialogues, requiring significant RAM and GPU.
4. Prefer quantized versions (q4, q5, q8) to reduce resource usage.
5. Start the LM Studio server; it will show a local API address (e.g., http://localhost:port).
6. Open the Config menu and set:
   • apiBaseUrl: local server address (Example: http://localhost:1234)
   • aiModel: ID or name of the model running in the server
   • localApiProvider: "lmstudio"

C. Offline Mode (No AI Required)

Play CobbleBrain without an AI connection.

Starting with version 1.4.0, you can enable Offline Mode and Offline Talk Mode to enjoy an adapted gameplay experience without internet access or an AI provider.

While AI-powered conversations are unavailable, many gameplay mechanics continue to work, allowing you to interact with your Pokémon, use actions, complete quests, and enjoy the mod offline.

How to enable it:

1. Open the Config Menu by pressing Y.
2. Enable Offline Mode.
3. (Recommended) Enable Offline Talk Mode for Pokémon dialogue and reactions.

Note: Using an AI provider is still recommended for the full CobbleBrain experience. Offline Talk Mode will continue to receive improvements and new features in future updates.

D. Interacting with Pokémon

• Use the command /mpk <message> to talk to your Pokémon.
• If listenToChat = true, any chat message can be interpreted by the AI.

How to Trigger Actions

Use the action HUD to make all your Pokémon perform the chosen action or encourage Pokémon through chat to perform actions!

Example: Squirtle, defend me! / Bulbasaur, want to eat some berries I dropped?

Primary Type-based Actions

These actions only work when the Pokémon has the right primary type.
Example: Charizard (fire, flying) can use cook, but Chandelure (ghost, fire) cannot.

• Cook (Fire): Can cook food and smelt ores. 5% chance of item turning into charcoal.
• Grow (Plant): Grows tree saplings and crops.
• Repair (Metal): Repairs tools and weapons up to a durability threshold.
• Shift (Ghost): Transports the player to an alternate dimension. Player becomes invisible, gains increased speed and jump height, but suffers from high weakness.
• Fish (Water): Pokémon can catch fish from nearby water sources.
• Nightmare Aura (Dark): Creates a terrifying aura that frightens nearby creatures.
• Light (Electric): Creates a temporary light source around the Pokémon.
• Scout (Flying): Sends the Pokémon to scout the surrounding area.
• Teleport (Psychic): Teleports the player to a marked location using the Ping System. Press G to ping the location you're looking at.
• Excavate (Steel): Digs and clears a tunnel through blocks, but each layer costs a fraction of the Pokémon's life, it stops automatically at 10% remaining life.

General Actions

These actions work with any pokemon!

• Attack: Pokémon attacks nearby mobs.
• Protect: Targets hostile mobs near the player; otherwise follows the player.
• Eat: Consumes edible items dropped on the ground (some foods and berries grant effects).
• Buff: Grants the player a positive status effect based on type.
• Debuff: Applies negative status effects to nearby mobs based on type.
• Rest (Sit): Pokémon rests in place and slowly regenerates health over time (configurable heal rate).
• Build: Pokémon places blocks from a marked chest to construct structures.
• Idle: Cancels commands and returns to normal behavior.

Configuration

CobbleBrain can be configured directly in-game through the mod config menu screen. You can open it by pressing Y or typing /cobblebrain openConfig in chat.

There you can customize:

• AI provider settings (apiKey, apiBaseUrl, aiModel)
• Gameplay Systems (Dialogue, Memories, Quests, Actions, etc.)
• Individual Action settings (enable/disable each action, custom cooldowns)
• AI prompts (instruct and other behavior settings)
• Wild Pokémon quest chances
• Raid settings
• Pokémon personalities (Personality Editor)

Recommended settings for new players:

• Selected Language — Changes the language used by the AI during conversations.
• Instruct — Defines how the AI should behave and respond. You can customize it to make Pokémon more serious, funny, emotional, roleplay-focused, or anything else you prefer.
• Personality Editor — Customize each Pokémon's Traits, Quirks, Likes, Dislikes, and other personality attributes through an intuitive in-game editor.

All the settings include tooltips explaining what they do!

Advanced users can still edit the generated configuration files in the /config folder if needed.
For the full list of variables and explanations, please check the CobbleBrain README on GitHub.
