GamesAI

Features

• /ask command — Ask AI questions directly from the Minecraft chat
• Multi-model support — Switch between AI models via -m / --model flags
• Multi-profile configuration — Define multiple AI backends (OpenAI, custom endpoints, etc.) with independent API keys, prompts, and base URLs
• Async execution — AI requests run off the main thread, never freezing the server
• Compatible with any OpenAI-compatible API — Works with OpenAI, local LLMs (Ollama / LM Studio), or self-hosted endpoints
• Auto-generated config — First run creates a default config/games_ai/config.json, no manual setup needed
• Multi-language support — Server-wide language switching (en_us / zh_cn), live reload without restart
• Conversation history — Per-player, per-model history with configurable length and auto-trimming
• Context-sensitive help — /gamesai help adapts to your current command context
• Debug mode — Toggle request logging for troubleshooting API issues

Building

Prerequisites

• JDK 21 (or newer)
• Gradle Wrapper (included — use gradlew / gradlew.bat)

Build

# Clone the repository
git clone https://github.com/pengzixuan30/GamesAI.git
cd GamesAI

# Build the mod
./gradlew build

The compiled .jar will be at: build/libs/games_ai-0.1.1-Fabric-xxx.jar

Run in Dev Environment

./gradlew runClient    # Launch Minecraft client with the mod
./gradlew runServer    # Launch a local test server

Quick Version Migration

For minor patch upgrades within 1.21.x, edit gradle.properties:

minecraft_version=<new_version>
yarn_mappings=<new_version>+build.X
fabric_version=<api_version>+<new_version>

Then rebuild and test. Check fabricmc.net/develop for recommended version combinations.

Server Notes

• History is in-memory only — server restart clears all conversations
• API costs — each /ask makes one HTTP request to the configured endpoint

Version Compatibility

More versions coming soon.
