# Unity SDK

This guide is used to guide developers to use RayNeo OpenXR Unity ARDK (hereinafter referred to as ARDK) in the Unity engine to create a basic AR scene, and publish the scene as an application that can run on RayNeo glasses.The Unity versions used in this guide are as follows:

* The Unity Editor version for X2 SDK is 2021.3.6f1c1.
* The Unity Editor version for X3Pro SDK is 2022.3.36f1.

If you are not familiar with the development of RayNeo ARDK applications, you can follow this guide to take the first step into the AR world. If you already have a certain level of knowledge about RayNeo ARDK application development and Unity engine development, you can also use this guide as an independent reference.For details of the glasses, please check: [Device Introduction](/rayneo-devdoc/x-series/device-introduction.md)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://rayneo-en.gitbook.io/rayneo-devdoc/x-series/unity-sdk.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
