Hey creators! We’ve released a comprehensive technical reference for Meta Horizon Worlds that should make your dev life much easier.
What is it?
The Meta Horizon Creator Manual is a community-sourced, Meta-endorsed, guide that documents core systems including gizmos, scripting, physics, entities, networking, grabbables, attachables, and more. It's a go-to reference when you want to know how parts of Meta Horizon work or what some of the TypeScript does (the guide focuses on horizon/core).
Note: the Creator Manual is not a tutorial; it is a technical manual focused on answering technical questions about Horizon and its "engine". For tutorials and introductory content, visit the creator documentation site.
When you'll want it and how to use it
Any time you are wondering "how does this system work?" or "what does this property do?" or "how do these APIs interact?" then you should open up this doc. It has a thorough table of contents at the top you can use to jump around. And at the bottom of the doc there is a list of every CodeBlockEvent and every TypeScript symbol in horizon/core; you can use those sections to jump around the doc as well.
Forum posts
If you find an error in the guide, want to recommend an edit, have a question, or feel that there is information missing, create a post in this forum including the relevant details. Please be specific about the section you are referring to and the edits you would make; if you are suggesting a new section, please describe where it would go, what it would cover, and why it isn’t covered by other existing resources. Be sure to include the Creator Manuallabel any time you post in the forum about the guide. Thanks!
