About this Mod

Player2NPC - Your AI Companion in Minecraft!

Powered by Player2

Ever wished you had a friend in Minecraft who could actually help you? Not just a pet that follows you around, but a true companion who can chop wood, mine ores, and even defend you from monsters?

Welcome to Player2NPC! This mod brings AI to life in your Minecraft world like never before. Powered by the groundbreaking Player2 AI and the PlayerEngine framework, these aren't your average villagers. These are fully embodied AI companions that listen to you, talk back, and interact with the world just like a real player.

This mod is an entry for the Player2 AI Game Jam, created by Goodbird.

Features

  • 🗣️ Natural Language Commands: Simply talk to your companion in chat. No clunky commands! Say "I need some wood for a chest" or "can you deal with that zombie?" and watch them spring into action.
  • 🤖 Embodied AI Agents: Your companions aren't just chatbots. They have bodies, inventories, and the ability to break and place blocks, use tools, and fight. They truly exist and act within your world.
  • Plug-and-Play: It just works! Once installed, you're ready to join the world and meet with your first AI friend. No complicated in-game setup required.
  • 🎭 Select Your Companions: Browse a cast of unique AI characters in, each with their own personality, appearance, and voice, provided by the Player2 platform. Press the 'H' key (configurable) to open the Character Selection screen and summon/dismiss your favourite characters.
  • 🤝 A True Companion: Need help crafting a shield? Ask them. Low on food? Send them hunting. Exploring a dark cave? They'll watch your back. Your companion is a dynamic part of your adventure.

Quick Start & Installation

Getting your AI companion into your world is easy! Just follow these two steps.

Step 1: Install the Player2 App

The AI that powers your companions runs through the Player2 desktop application. It acts as a secure gateway to the AI models and is required for the mod to work.

  1. Download the Player2 App HERE
  2. Install and launch the app. It will run in the background.
  3. That's it! The app handles everything else automatically.

The Player2 app provides the AI "brain" for your NPC. The mod provides the "body" in-game.

Step 2: Install the Mod

This works like any other Fabric mod.

  1. Install Fabric and the Fabric API.
  2. Install Cardinal Components and PlayerEngine.
  3. Download the latest version of the Player2NPC mod from the Files tab.
  4. Drop the JAR file into your mods folder.
  5. Launch Minecraft!

How to Play

  1. Launch Minecraft with the mod installed and the Player2 app running.
  2. Join a single-player world.
  3. Select your favourite character in the Player2 app (Optional)
  4. Your new AI companion will appear nearby!
  5. Open the chat and start talking to them. Try saying hello, or ask them to do something for you!
