[Absolute Beginner's Edition] No programming experience needed. Start from sample projects and breeze along with the AI. You don't write the code. Ask the AI, and build your own world inside your Meta Quest. You put on your Meta Quest and stand inside a world you made. A character you called up is sitting on the floor of your room. This book shows people who are new to programming how to build experiences like that together with AI. You'll build WebXR projects, which you can play just by opening their address in the Meta Quest browser. There are no app store applications and no difficult development tools. The AI writes the program. You decide what you want to build, ask the AI, and check the result on your Quest. What you learn in this book isn't how to write code. It's how to make things with AI. ■ The four projects you'll build - A Planet in Space (VR): A moon circles a planet floating in space - Balloon Pop (VR): A 60-second game where you aim a beam at balloons and pop them - Nekobi in Your Room (MR): Nekobi sits on the floor or desk in your room - Ball Play in Your Room (MR): The ball you throw bounces off your real walls and floor In the last chapter, you'll publish your project on the internet, hand it out with a QR code, and have your friends and family play it. ■ Who this book is for - People who have a Meta Quest 3 / 3S and a Mac and want to build their own VR or MR projects - People who have never programmed, or have only tried it a little - People who want to try using AI (Claude Code or Codex) to build projects ■ What you'll learn - How to ask the AI so it builds what you had in mind - How 3D worlds work (placing things, light, motion, and detecting collisions) - How VR and MR work (finding the surfaces of your room and reading your hands) - How to find the cause of a problem and fix it together with the AI - How to publish your project on the internet and have people play it ■ Contents - Chapter 0: Play on Your Quest First - Chapter 1: Get Ready to Build - Chapter 2: Get Good at Asking the AI - Chapter 3: A Planet in Space - Chapter 4: Balloon Pop - Chapter 5: Nekobi in Your Room - Chapter 6: Ball Play in Your Room - Chapter 7: Publish It and Let Others Play - Appendices: Prompt Index, Troubleshooting, Glossary, Test Environment ■ Bonus downloads You can download the template, each chapter's start and final versions, the 3D model of Nekobi, and a prompt collection from the bonus page. The same page has a sample gallery where you can play all four projects on your Quest right away. You can reach the bonus page from the QR code or the address in the book. The code is under the MIT License (the 3D model of Nekobi has its own terms). ■ Let the AI read this book You're free to load this book into an AI you use yourself.
