Build World is a Claude Code plugin and skill that pairs your coding agent with Thrixel-generated 3D assets to build interactive worlds in Three.js, Roblox, Unity or Unreal Engine.

This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL.

## How to build an interactive 3D web world with your agent with Build World

Repo: [thrixel/build-world](https://github.com/thrixel/build-world) | Difficulty: Intermediate | Time: 1 hour | Basis: From the README

Install the plugin so Claude Code writes the Three.js logic while Thrixel generates the 3D assets.

**Who it is for:** A web developer who wants a playable 3D scene but cannot model assets.

**The problem:** Making good 3D assets by hand or with a coding agent alone is slow.

**The outcome:** A Three.js world with generated assets that the agent iterates on.

### Steps

1. Check tools with `claude --version` and `uv --version`
2. Log in with `uvx thrixel-mcp@latest login`
3. Run `claude plugin marketplace add thrixel/build-world` then `claude plugin install thrixel@thrixel`
4. Ask Claude Code to build a Three.js world from your idea

### Prompt to paste into your agent

```text
Using the thrixel/build-world plugin, build a small Three.js scene of <idea> with generated assets. Confirm `claude mcp list` shows the Thrixel connector as Connected before starting.
```

### Caveat

Asset generation runs on Thrixel's service, so you need a Thrixel account and its terms apply.

Risk, remote script: The prerequisite installs pipe scripts from claude.ai and astral.sh into your shell.

## How to prototype a game level in Roblox, Unity or Unreal with Build World

Repo: [thrixel/build-world](https://github.com/thrixel/build-world) | Difficulty: Advanced | Time: 2 hours | Basis: From the README

Use the same skill with a game engine target so the agent sets up scenes and Thrixel supplies assets.

**Who it is for:** An indie developer testing a level idea before committing art budget.

**The problem:** Placeholder art makes prototypes hard to judge.

**The outcome:** An engine project with generated assets placed by the agent.

### Steps

1. Install the plugin and log in to Thrixel
2. Open your Roblox, Unity or Unreal project folder
3. Describe the level and target engine to the agent
4. Let the loop build, evaluate and refine

### Prompt to paste into your agent

```text
With build-world, prototype a <engine> level for <game idea> using Thrixel assets. List the assets generated and confirm they are imported into the project.
```

### Caveat

The README walks through Claude Code; other agents work but need their own setup.

## How to create an educational or historical 3D recreation with Build World

Repo: [thrixel/build-world](https://github.com/thrixel/build-world) | Difficulty: Intermediate | Time: 1 hour 30 minutes | Basis: From the README

Use Build World beyond games for simulations, virtual tourism or historical recreations.

**Who it is for:** A teacher who wants students to explore a historical site interactively.

**The problem:** Interactive 3D lessons usually need a dedicated studio.

**The outcome:** An explorable 3D experience built by the agent with generated assets.

### Steps

1. Install the plugin and log in
2. Describe the place, era and interactions you want
3. Review each iteration and give feedback
4. Remove the plugin later with `claude mcp remove thrixel` if needed

### Prompt to paste into your agent

```text
Using build-world, create an explorable Three.js recreation of <place and era> with clickable info points. Confirm every info point opens and the scene loads in a browser.
```

### Caveat

Historical accuracy depends on your brief; the tool generates assets, not research.
