New: ShameGPT

ShameGPT for Minetest 🔗

ShameGPT is a local AI chatbot integration for Minetest. It allows players to interact with an AI model running on their own machine via Ollama. By default, it is optimized for lightweight models like Gemma 3 (270m) to ensure a smooth gaming experience even on modest hardware.

🚀 Features 🔗

Local & Private: No API keys required. Your data never leaves your computer.

Asynchronous Processing: The game won't freeze while the AI is thinking; responses appear in chat once ready.

Highly Configurable: Choose any model you have installed in Ollama via the Minetest settings menu.

Sanitized Output: Automatically cleans ANSI escape codes and formatting artifacts from AI responses.

🛠 Prerequisites 🔗

Before installing this mod, you must have the following:

Ollama installed and running: Download it from ollama.com.

Minetest 5.0 or later.

An AI Model: By default, this mod looks for gemma3:270m. You can pull it using:

ollama pull gemma3:270m

📥 Installation 🔗

Clone or download this repository into your Minetest mods folder.

Rename the folder to shamegpt.

Critical Security Step: Because this mod executes system commands to talk to Ollama, you must grant it trusted status. Add the following line to your minetest.conf file:

secure.trusted_mods = shamegpt

⚙️ Configuration 🔗

You can change the AI model used by the mod in the Settings tab of the Minetest main menu:

AI Model (model_name): The name of the model installed in Ollama.

Default: gemma3:270m.

Recommendation: Use lightweight models (under 3B parameters) to prevent CPU spikes while playing.

🎮 Usage 🔗

Once in-game, any player with the interact privilege can use the following command:

/shamegpt <your message here>

Example: /shamegpt Why is there a creeper in my house? (Wait... wrong game!)

Security Note 🔗

The mod includes a safety filter that blocks symbols like ; & | [cite_start]$ to prevent command injection, ensuring that players can only send text prompts to the AI.
