NoesisGUI Unreal Engine Localization Demo

Introduction

This demo shows one way to localize your user interface to multiple languages. The main focus points of this demo are:

• Shows how to use ResourceDictionarys to map from labels to the actual text to display in the various languages supported.

• Shows how to use the LoadXaml function in a Blueprint to load the dictionaries.

Demo Breakdown

C++ Code

• LevelToColorConverter.h: Implements an IValueConverter used to convert the SoundLevel and MusicLevel properties exposed by the view model to colors.

• MainWindow.h: Implements a minimal code-behind for MainWindow.xaml.

• LocalizationGame.cpp: Implements a minimal game module that registers the NoesisGUI native components.

Blueprint

• NoesisBlueprint'/Game/MainWindowView.MainWindowView': It's a NoesisView for NoesisXaml'/Game/MainWindow.MainWindow' (MainWindow.xaml).

• Blueprint'/Game/Language.Language': This Object derived Blueprint represents a language for the UI. It exposes two properties, the Name of the language and the Resources, which are loaded from a NoesisXaml using the LoadXaml function from the NoesisFunctionLibrary.

• Blueprint'/Game/ViewModel.ViewModel': An Object that is used as the DataContext for NoesisBlueprint'/Game/MainWindowView.MainWindowView'. It exposes the list of supported Languages and the currently SelectedLanguage, as well as the previously mentioned SoundLevel and MusicLevel.

• TestLevel - Level Blueprint: Creates a Widget from NoesisBlueprint'/Game/MainWindowView.MainWindowView', adds it to the viewport and captures mouse input. It also creates several instances of Blueprint'/Game/Language.Language' and an instance of Blueprint'/Game/ViewModel.ViewModel' that it sets as the DataContext of the Widget.

Project Settings

• NoesisGUI Project Settings: Sets the NoesisXaml NoesisXaml'/Game/Resources.Resources' as the global application ResourceDictionary.
