Getting Start NoesisGUI for Unreal Engine

Just do it first, came back to ask why.

There is one video tutorial based on this text tutorial, here is the link:

link:https://www.bilibili.com/video/av47290316

Before you start:

1.Install Unreal Engine 4.21 from https://www.unrealengine.com/en-US/what-is-unreal-engine-4

2.DownLoad NoesisGUI 2.2.0 Unreal 4 Plugin from https://noesisengine.com/developers/downloads.php

3.Install Microsoft Visual Studio 2017 include blend from https://docs.microsoft.com/en-us/visualstudio/releasenotes/vs2017-relnotes

Let's get started:

Blend Project section:

1.Create one WPF Project using Visual Studio 2017

2.Find and modify the MainWindow.xaml file from Window To UserControl.

3.Modify MainWindow.xaml.cs, also Window To UserControl.

4.Add new file name it ElementToVisibility.cs and add code below:

using System;
using System.Globalization;
using System.Windows.Data;
using System.Windows;

namespace DemoUI
{
    public class ElementToVisibility : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            bool isVisible = (bool)value;

            Visibility visibility = (Visibility)parameter;

            if (isVisible)
            {
                visibility = Visibility.Visible;
            }
            else
            {
                visibility = Visibility.Hidden;
            }
            return visibility;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }
}

5.Add one three button and three label to MainWindow.xaml. the finish code is like this.

<UserControl x:Class="DemoUI.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:DemoUI"
        mc:Ignorable="d"
         Height="1080" Width="1920">

    <UserControl.Resources>
        <local:ElementToVisibility x:Key="ElementToVisibility"/>
    </UserControl.Resources>

    <Grid Background="#FF7350D1">
        <Button Content="ClickToShowMessage" HorizontalAlignment="Left" Margin="350,100,0,0" VerticalAlignment="Top" Width="200" Height="100" Command="{Binding ClickToShowMessage}"/>
        <Button Content="ToggleVisibility" HorizontalAlignment="Left" Margin="350,300,0,0" VerticalAlignment="Top" Width="200" Height="100" Command="{Binding ToggleVisibility}"/>
        <Label Content="{Binding Message, Mode=TwoWay}" HorizontalAlignment="Left" Margin="600,100,0,0" VerticalAlignment="Top" FontSize="20"/>
        <Label Content="Toggle Visibility" Visibility="{Binding ElementToVisibility, Converter={StaticResource ElementToVisibility}}"  HorizontalAlignment="Left" Margin="600,300,0,0" VerticalAlignment="Top" FontSize="20"/>
    </Grid>
</UserControl>

Blueprint section:

There is two file under Blueprint folder,these two files are the blueprint function for easy to follow up,you can copy the content of these files when create them.

1.Create Unreal Engine 4 Blank Project named DemoUI ( though this name is up to you,mine is this one, recommand using the name for easy to follow up)

2.Copy the downloaded NoesisGUI Plugin to Project Location.

3.Close the unreal engine editor,reopen the editor,click yes when it show the dialogue to intall the plugins.

4.Copy the whole WPF project to the folder under Unreal Project Content folder.

5.Right Click on the content browser, choose NoesisView to create one blueprint,name it MainWindowView

6.Open blueprint MainWindowView under class setting, under Inspctor >> Noesis View, choose MainWindow.xaml,click Enable PPAA.see picture below:

  • Create one varible name Message, type String show as below picture

  • Create one varible name MessageCount, type integer show as below picture

  • Create one varible name ElementToVisibility, type Boolean show as below picture

  • Create one function name ClickToShowMessage,copy the code below:

8.Drag the SpawnNoesis blueprint to map, run the game, but the toggleVisiblity does not work. stop the game, let's do the last section to make the toggleVisiblity work.

Coding section:

1.Open Unreal Project if it has not been opened.

2.Create one c++ file from Files to generate the build files. see picture below.

3.Find and open DemoUI.build.cs in visualstudio 2017. replace code

PrivateDependencyModuleNames.AddRange(new string[] {  });

To the code below.

 PrivateDependencyModuleNames.AddRange(new string[] { "Noesis", "NoesisRuntime" }); 

Please refer to assosiate source code file named DemoUI.build.cs for the final result.

4.Add code to DemoUI.h

#include "NoesisRuntime.h"

5.Add new file MainWindow.h to project.

6.Add the below code to MainWindow.h,

#pragma once
#include"DemoUI.h"
namespace DemoUI
{
////////////////////////////////////////////////////////////////////////////////////////////////////
class MainWindow : public Noesis::UserControl
{
private:
    NS_IMPLEMENT_INLINE_REFLECTION(MainWindow, Noesis::UserControl)
    {
        NsMeta<Noesis::TypeId>("DemoUI.MainWindow");
    }
};
}

7.Create new file named ElementToVisibility.h to project.

8.Add below code to ElementToVisibility.h :

#pragma once
#include "DemoUI.h"

namespace DemoUI
{
	class ElementToVisibility : public Noesis::BaseValueConverter
	{
	public:
		bool TryConvert(Noesis::BaseComponent* value, const Noesis::Type* targetType, Noesis::BaseComponent*,
			Noesis::Ptr<Noesis::BaseComponent>& result)
		{
			if (targetType == Noesis::TypeOf<Noesis::Visibility>() && Noesis::Boxing::CanUnbox<bool>(value))
			{
				bool isVisible = Noesis::Boxing::Unbox<bool>(value);
				Noesis::Visibility resultValue = Noesis::Visibility::Visibility_Visible;
				resultValue = isVisible ? Noesis::Visibility::Visibility_Visible : Noesis::Visibility::Visibility_Hidden;
				result = Noesis::Boxing::Box(Noesis::Visibility(resultValue));
				return true;
			}
			return false;
		}

	private:
		NS_IMPLEMENT_INLINE_REFLECTION(ElementToVisibility, Noesis::BaseValueConverter)
		{
			NsMeta<Noesis::TypeId>("DemoUI.ElementToVisibility");
		}
	};
}

  1. replace below code to Demo.cpp
#include "DemoUI.h"
#include "Modules/ModuleManager.h"
#include "MainWindow.h"
#include "ElementToVisibility.h"

class DemoUIGameModule : public FDefaultGameModuleImpl
{
	virtual void StartupModule() override
	{
		NsRegisterComponent<DemoUI::ElementToVisibility>();
		NsRegisterComponent<DemoUI::MainWindow>();
	}

	virtual void ShutdownModule() override
	{
		NsUnregisterComponent<DemoUI::ElementToVisibility>();
		NsUnregisterComponent<DemoUI::MainWindow>();
	}
};
IMPLEMENT_PRIMARY_GAME_MODULE(DemoUIGameModule, DemoUI, "DemoUI" );

  1. Close Unreal Engine Editor to rebuild the code project, reopen Unreal Engine editor after complete rebuild to run the demo.

Now you know how to bring Noesis power to Unreal Engine 4

You can’t perform that action at this time.
