查找包文档

The Unity Manual provides documentation for a specific version of Unity. For package documentation, each package has its own version, so each package provides documentation for a specific version of that package. For this reason, the package documentation isn’t part of the main Unity Manual documentation. Instead, documentation for each package lives on its own website on Unity’s documentation server.

要访问特定包的文档，您有两个选择：

• 获取最新版本的文档（从 Unity 手册）。
• 获取特定包版本的文档（从 Package Manager 窗口）。

When the package page opens, the top of the page has four links (A) and a drop-down menu (B) where you can select a different version:

Use the links at the top of the page to view the documentation for the package’s core usage (Manual), the package’s Scripting API documentation, the Changelog for the package, and the License information for the package.

获取最新版本的文档

Each version of the Unity Manual documentation provides a list of released and pre-release packages, a list of built-in packages, and a list of packages by keyword. Each list has links to the matching package documentation which you can use with that version of Unity. Note: Only packages that are compatible with the version of Unity matching the documentation appear in these lists.

You can expand the entries in the sidebar navigation (A) to access specific information about each package. Information includes the list of compatible versions, a brief description of the package, and any associated keywords. Or you can click the link on the list pages (B) to directly open the most compatible version of that package documentation that matches the documentation version.

如果在此列表中找不到所需的包，可能有以下几种原因：

• 这个包与此 Unity 版本不兼容。
• It’s an experimental or private package. Some packages aren’t available to everyone because someone outside of Unity is developing them or because they’re under a special license.

You might be able to access the documentation through the Package Manager window for packages released in another version of Unity. For private packages, try to contact the developer directly to request access.

获取特定包版本的文档

You can find out more about a package that comes from a registry (not Asset Store) by viewing its documentation, changelog, or license information.

To access any of these pages, you can click the Documentation, Changelog, or Licenses links from inside the Package Manager window.

要访问特定包版本的文档，请执行以下操作：

1. Open the Package Manager window in Unity.

2. 遵循查找包中的准则找到您想要的特定包和版本号。

3. Click the Documentation link to open the documentation for the selected version of the package.

   Note: If the package is installed, you can right-click the Documentation, Changelog, or Licenses links and select Open Locally. The Package Manager opens your file browser at the appropriate folder.

You can follow this procedure for any version of a package that comes from a registry (not Asset Store). Note that the documentation isn’t necessarily different for each package version release, because some version updates (patches) involve only bug fixes or trivial changes.
