Guides

Game creation, multiplayer, AI assets and browser workflows, step by step.

Start here

Make your first game with AI

Describe your idea, build its world and rules, then test and share it. Start with the AI creation guide or follow a first-game project step by step.

Level 1

Create models, textures and audio

Give your game its own look and sound. Generate the assets you need and refine them in the world you are building.

Level 2

Play with friends

Build a game around something friends can do together. Use Gessa’s multiplayer engine, test the shared rules and publish a game link to share.

Level 3

Go deeper

Once you are comfortable building and sharing, understand what sits underneath: the engine around Three.js, what an AI game engine is, and how the field compares.

Switching or stuck

Migrate and troubleshoot

Coming from another engine, or hitting a wall? Move your assets across from Unity, Roblox or Three.js, and fix the common problems by cause and fix.

Common questions
