Finding packages and feature sets

The Package Manager window provides several ways to help you find a specific package or feature set:

在 Package Manager 窗口的顶部，有几个控件可帮助您缩小包列表的范围


(A)	Packages 列表上下文	Choose the “context” that determines what appears in the list. The context might be the source of the package, such as a registry server, the Asset Store, or the Unity Editor itself (for built-in packages). However, the In Project context displays only those packages and feature sets that are already installed in the current project, regardless of their origin. For example, you can choose the My Assets context to display only Asset Store packages available to you in the list, or choose the In Project context to display only Unity packages and feature sets that are already installed in your project.
(B)	Sort	Sort the list in either ascending or descending order by name, published date (Unity Registry, My Registries, In Project only), purchased date (Asset Store packages only), or recently updated (In Project and My Assets only). For example, if you want to find a Unity package that had a recent update but you can’t remember the name of it, try sorting by Recently updated in descending order and browse the list from the top down to find it. Sorting affects the items under each expander, but leaves the expanders in place. If you sort from Z-A, the Package Manager reorders all the feature sets from Z- A inside its expander, and all the packages under each expander but doesn’t mix the content in the list.
(C)	Filters	Select options to narrow down the packages listed. Packages listed in My Assets have enhanced filtering options: - Status (Downloaded, Update available, Unlabeled, Hidden, Deprecated) - Categories (2D, 3D, Audio, Templates, Tools, etc.) - Labels (Custom labels you define in the Asset Store)
(D)	搜索	使用搜索框按名称查找 Unity 包或 Asset Store 资源包。

These controls help narrow down which packages and feature sets appear in the list view and in what order. This makes it easier to find what you are looking for or help you browse when you don’t know exactly what you want.

当您同时使用多个控件时，可以缩小列表中显示的匹配集。

After you find the Unity package you need, you can select it, then potentially locate a specific version in the details view. For feature sets, there is always only one version available, so you can either install it or remove it.

查找特定版本

要查找某个特定的包版本，请执行以下操作：

在 Unity 中，打开 Package Manager 窗口（导航到 Unity 的主菜单，然后选择 Window > Package Manager）。
If you are looking for a pre-release package, follow these steps:
- Select Project Settings under the Advanced menu.
  
  Project Settings opens the Package Manager project settings window
  
  The Package Manager Project Settings window appears.
- Under the Advanced Settings group, enable the Enable Pre-release Packages option.
- Close the Project Settings window. Any pre-release packages now appear in the list with the indicator.
您可以浏览包列表或使用以下方法之一查找特定包：
- 按名称或关键字搜索包。
- 对列表进行排序（例如，按上次更新时间降序排序，以查找最近更新的包）。
- Apply filters to the list.
Select a package from the list of packages.
In the details view, select the Version History tab. If multiple versions are available, expand the entries to see information specific to each version.

Version numbers for installed packages display in multiple places and the recommended version appears on the Update button
You can perform a variety of actions when you expand a specific version in the Version History tab:
- You can view the changelog for that version and click See changelog to see the full list of changes across versions.
- If you don’t already have this package installed in your project, you can install this version.
- If another version of this package is already installed in your project, you can update the package to this version.
- If you installed this package in your project but don’t want it anymore, you can remove the package from your project.
