Step by step

The workflow

Follow the sequence once, then adapt the prompts, checks, and handoffs to your own setup.

5 steps

Step01

Build the Base Game

Start by creating the initial 3D game on a ChatGPT Site. This could be a simple dungeon crawler with a player character, enemies, and a basic environment.

Step02

Create a Custom 'Skill'

Develop a custom skill, like the 'dungeon site' skill, that provides a set of instructions and rules for a model like Codex. This skill defines what a 'room' is, including its properties, dimensions, and player controls.

Step03

Enable User Creation with the Skill

Allow other users to install your custom skill. This empowers them to contribute to your game world using the framework you defined.

Step04

Generate New Content with Natural Language

Once the skill is installed, users can generate new game rooms or levels simply by describing their vision in a prompt to a model like Astra.

Example prompt
Create a new dungeon room with a Stranger Things theme. I want to be on the moon surface. I want to be in a volcano.

The skill guides the model to translate these creative, high-level descriptions into a functional game level that adheres to the established rules.

Step05

Link the Community Content

Establish a method for discovering and linking user-created rooms, such as using a specific hashtag on social media. This allows you to build a massive, interconnected game world over time.
