A lightweight, fully asynchronous Fabric mod that brings a friendly AI player named Little Whale into your Minecraft server. Powered by any OpenAI-compatible API, it can chat with players in private or public, understand context, and speak their language.

✨ Features

  • 3 Chat Modes – Switch between private, public, or mixed mode:
    • Private (mode 1): Players use @ai <message> to talk to the AI. Only the sender sees the reply.
    • Public (mode 2): Every public chat message is treated as conversation with the AI. The AI replies publicly to everyone. Context is globally shared.
    • Mixed (mode 3): @ai triggers private conversation, while normal chat triggers public AI replies. Private and public contexts are kept separate.
  • Player-aware AI – In public/mixed modes, the AI sees who said what via [PlayerName]: message format. It can address players by name naturally.
  • Multilingual – The AI automatically replies in the same language the player used (Chinese, English, etc.).
  • Plain Text Only – The AI is instructed never to use Markdown, code blocks, or special formatting, keeping output clean for the in-game chat.
  • Safe & Non‑blocking – All HTTP requests run on background threads; the server main thread is never blocked.
  • Context Management – Auto-clears conversation history after a configurable interval or manually via commands.
  • Fully Configurable – Change the API endpoint, model, temperature, system prompt, prefix, and more through config/aichat.json.
  • Admin Commands – Powerful /aichat commands to clear contexts, reload config, and view status.

📦 Installation

  1. Install Fabric for Minecraft 1.21.8.
