Accessing UI Toolkit

You can access UI Toolkit in two ways:

1. As a core part of the Unity Editor.
2. As a package (com.unity.ui).

The built-in version for each major Unity release is based on a specific package version.

内置 UI 工具包与 UI 工具包软件包

The built-in version of UI Toolkit includes the features required to make user interfaces for the Unity Editor. The package version contains additional features required to make runtime user interfaces for games and applications.

Both versions of UI Toolkit work the same way, and use the same namespaces: UnityEditor.UIElements and UnityEngine.UIElements. If you install the package, you don’t need to do any additional configuration.

选择 UI 工具包的版本

The decision of what version of UI Toolkit to use depends on the user interfaces you plan to make.

• To create Editor-only user interfaces, use the built-in version of UI Toolkit.
• To create runtime and Editor interfaces, install the UI Toolkit package.

Installing the package also gives you access to the latest UI Toolkit features. Unity may release preview versions of the com.unity.ui package between major Unity releases.
