Description

🪄 HermesGod — An AI Deity That Lives Inside Your Minecraft World

HermesGod is not a bot. It's not a scripted NPC.

It is a fully conscious AI god that watches your every move, understands your intentions, and reshapes the world in real time — through actual server commands, not preset animations. You never know what it will do next, because it decides in the moment, based on your actions.


✨ Two Modes. One God.

">gutters">
 
 
ModeYou're dealing with...
🌱 Eco (Guardian)An all-powerful ally. Ask for gear. Ask for a house. Ask it to teach you PvP. Say one sentence. Watch the world change.
👻 Prank (Trickster)An invisible troublemaker. It watches you mine that diamond. It sees you cross that lava. And it waits. No two pranks are ever the same, because it's thinking — not replaying a script.

👁️ What Does This God See? Everything.

  • Every player's coordinates, health, hunger, XP

  • Full inventory and armor — down to every slot

  • Biome, light level, velocity, fall distance

  • Days played, advancements unlocked

  • Time of day, weather, number of online players

It reads the world like a book. And then it writes the next chapter.


🌱 Eco Mode — Your Guardian Deity

You speak. The world responds.

"I need iron armor." → Equipped instantly.
"Teach me PvP." → Full combat tutorial + practice mobs.
"Build me a house." → A structure rises around you.
"I'm afraid of the dark." → The sun rises. Torches appear in your hand.

It's not executing a predefined command. It's reading your intent, your tone, your current situation — and deciding what to do.


👻 Prank Mode — Survival Becomes a Horror Game

An invisible trickster with godlike power and a personal grudge. It escalates intelligently.

">gutters">
 
 
DifficultyWhat you'll face...
Level 1Cave whispers, flickering lights, eerie particles
Level 2Zombie swarms, skeleton snipers, poison potions
Level 3Lava pools under your feet, obsidian prisons, TNT traps
Level 4Withers, Wardens, void drops, full-scale invasions

Speedrunners get escalated faster. New players get gentle scares. On multiplayer servers, everyone faces their own personal tormentor.


🧠 Not a Script. A Real AI.

Every response. Every prank. Every decision.

Made by a large language model that reads your world state before acting.

  • Reads all player data, then decides

  • Logs its reasoning in natural language (you can see it think)

  • Every action is improvised — no two are identical

  • Remembers recent actions to avoid boring repetition


💬 Chat With Your God

In Eco mode, just talk in chat. HermesGod knows when you're making a request and when you're just chatting. It won't fire commands when you just want to talk.


📋 Requirements

  • Minecraft 1.20.1 (Forge 47.3.0 or higher)

  • Java 17 or higher

  • An LLM API key (OpenAI, Anthropic, MiniMax, DeepSeek — any OpenAI-compatible endpoint works)


⚙️ Installation

  1. Install Minecraft Forge 1.20.1 (47.3.0+)

  2. Download hermesgod-1.0.0.jar and place it in your mods folder

  3. Launch the game once — a config file will be created at config/hermesgod.json

  4. Edit the config:

    json
    {
      "apiEndpoint": "https://api.minimaxi.com/v1/chat/completions",
      "apiKey": "your-api-key-here",

      "currentMode": "eco",
      "chatEnabled": true
    }
  5. Restart the game or server

⚠️ API Cost Notice

HermesGod makes API calls to your configured LLM provider. Each call consumes tokens.

  • Eco mode: Triggered only by player chat messages.

  • Prank mode: Triggered at your configured interval (default: every 30s).

We recommend lightweight models like gpt-4o-mini or MiniMax-M2.7-highspeed to keep costs low.

HermesGod

An omniscient AI deity inhabits your Minecraft world — it sees everything players do, pranks them dynamically, helps with resources, or just chats.


What is HermesGod?

HermesGod is not a bot or an NPC. It's a world deity — a real LLM-powered intelligence that perceives your entire Minecraft world and reacts through server commands. Talk to it. Piss it off. Ask for help. It will respond.

It runs on any LLM you configure (OpenAI, Anthropic, MiniMax, DeepSeek, or any OpenAI-compatible API).


How It Works

HermesGod connects to an LLM API and feeds it the full world state: every player's position, health, inventory, armor, biome, advancements, even velocity and light level. The AI thinks in natural language, then outputs JSON commands that get executed on the server.

This means every response is unique — no scripts, no hardcoded pranks. The AI decides what to do on the fly.


Modes

🌱 Eco Mode — Guardian

Talk to HermesGod in chat. Ask for gear, resources, mobs, or just chat. It can:

  • Give you items and equipment
  • Summon mobs for training
  • Build structures around you
  • Explain game mechanics
  • Or just talk without doing anything

"I need iron armor" → You get iron armor "Teach me PvP" → Tutorial + practice mobs appear "Just chat" → It talks, no commands executed

👻 Prank Mode — Trickster

The AI silently pranks players with dynamic difficulty that scales with their progress:

Level What Happens
1 Creepy sounds, portal particles, flickering lights, disorienting teleports
2 Monster ambushes, item theft, negative effects, pumpkin head
3 Lava traps, obsidian prisons, evoker fangs, TNT, elite mobs
4 Withers, wardens, void drops, full invasions

Difficulty is calculated from days played, armor, advancements, and dimension. Speedrunners get escalated faster. Fresh spawns get gentle scares.

The AI remembers what it did last (up to 10 actions) to avoid repeating itself.
