A virtual environment roleplaying game where a user-created NPC (non-playable character) roams about to achieve a given objective:

• Similar to traditional video games-- but way more AI-heavy. User is in "copilot" mode.

LLMs have the power to behave as NPCs whch taken on states, personalities, character-like qualities, and most importantly-- develop heuristics to pursue (modeled by one or many heuristic functions often). I use gpt-3-turbo to explore these capabilties.

This is an open-source project I am building and adding to over time. Feedback and contributions are welcome, see Contributions .

• Agent is the NPC exploring the world, currently a pixelated 2D plot of land
• Impassable tiles: cannot be passed
• Plantable (passable) tiles: a Plant layer with Plantable tiles and plants but not currently in use by Agent
• Commands for Plantable tiles:
  • Press S to plant 1u food
  • Press D to harvest 1u food

• gpt-3.5-turbo via OpenAI API
• List of Actions it can perform (up, down, L, R)
• Copilot style: AI Agent by default, but user interjections take precedent
• Ability to evaluate Surroundings
• Actions fluctuate based on Sleepiness values (which it self-assigns)

• Agent contains all Agent-related code
• ui-admin contains all environemnt-related code
• Used OpenAI API for (1) decision-making, (2) interacting with frontend (via wss)
• Tiled is the map editor. See ui-admin/src/assets
• Phaser and Grid Engine Plugin used for rendering environment

Meant as a proof of concept and is a work in progress. Errors may occur.

Designed to run locally. Follow steps here to run:

1. Update the agent/env.json file with your OPENAI_API_KEY
2. I've only tested with `Node.js 16.19.0``
3. From the gptrpg folder, run npm install to install dependencies for everything
4. Run npm start in the main folder. This will start up the agent and front-end. The front-end will be at http://localhost:3000

• Heuristic goal-setting
• More agent actions (eat, harvest some shit, sing, vibe, etc.)
• More states of being (emotions)
• Web UI

Contributions are welcome. Creativity is welcome. Please make a pull request at the project repo.
