Unity Compatibility

Minimum Unity: 2021.3

Package Dependencies

  • com.unity.modules.androidjni (1.0.0)
  • com.unity.modules.physics (1.0.0)
  • com.unity.modules.screencapture (1.0.0)
  • com.unity.modules.uielements (1.0.0)

📈 Improvements

  • Color related components, such as `ColorSlider` or `ColorSwatch`, support now a value of type `UnityEngine.Gradient` instead of `UnityEngine.Color` for more flexibility.
  • Removed the `disabled` boolean property on App UI components from the public C# API. The `disabled` attribute in UXML has been replaced by `enabled` UXML attribute. This change has been made in order to be more consistent with Unity 2023.3, where `enabled` UXML attribute is provided by UI Toolkit on any VisualElement.
  • Replaced `Nullable` properties in components by a custom serializable implementation called `Optional`
  • Renamed `Panel.dir` property with `Panel.layoutDirection`.
  • Replaced the `Divider.vertical` property by `Divider.direction` enum property.
  • Removed the `ApplicationContext` class and `VisualElementExtensions.GetContext()` method, replaced by the ne `ProvideContext` and `RegisterContextChangedCallback` API.
  • Replaced `ActionGroup.vertical` property by `ActionGroup.direction` enum property.

✨ Features

  • Added support of new UI Toolkit Runtime Bindings feature through bindable properties in each App UI components. More than 420 properties can now be bound (2023.2+).
  • Added support to new UI Toolkit Uxml Serialization using source code generators.
  • Added `BaseVisualElement` and `BaseTextElement` classes which are used as base class for mostly every App UI component
  • Added numerous custom PropertyDrawers for a better experience in UIBuilder (2023.3+)
  • Added the support of `Fixed` gradient blend mode in ColorSwatch shader.
  • Added `.appui-row` USS classes which support current layout direction context.

⚡ API Changes

  • Starting Unity 2023.3, App UI will not provide any `UxmlFactory` or `UxmlTraits` implementation, as they become obsolete and replaced by the new UITK Uxml serialization system.
