Luna UI Documentation

Luna UI provides utilities to automatically disable unrelated interactable elements using the LunaUIManager, enabling Unity's auto navigation to function without manual setup.

See the Disable Other Views On FadeIn field in UIView or UIViewComponent.

Each UI Toolkit panel features a focus ring that determines the focus order of elements. You can learn more about this feature here:

Change what element is focused next

You can manually determine what element is focused next.

csharp

myVisualElement.RegisterCallback<NavigationMoveEvent>(e =>
{
    switch(e.direction)
    {
        case NavigationMoveEvent.Direction.Up: U.Focus(); break;
        case NavigationMoveEvent.Direction.Down: D.Focus(); break;
        case NavigationMoveEvent.Direction.Left: L.Focus(); break;
        case NavigationMoveEvent.Direction.Right: R.Focus(); break;
    }
    e.StopPropagation(); // Prevent further processing of the event
    myVisualElement.focusController.IgnoreEvent(e); // Prevent default navigation
});
