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):
@aitriggers private conversation, while normal chat triggers public AI replies. Private and public contexts are kept separate.
- Private (mode 1): Players use
- Player-aware AI – In public/mixed modes, the AI sees who said what via
[PlayerName]: messageformat. 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
/aichatcommands to clear contexts, reload config, and view status.
