Csharp testing on Windows 11 version 26052 with Dot net 8.0.100 and Godot engine 4.2.1 : signals
Dot net 8 Csharp testing with Godot : signals
In this article, i will explain what is a signal used in godot engine to connect to a C# method.
About the author...
since 2001, Insider since 2014.
Thanks to Microsoft EMEA GBS to let me participate in the year 2014 to the Insider project during my work. Then, This Windows test project, here in version 11, is based on the cycle of the insider Preview Builds, now in the Dev Channel: it is fun to test the new features. I can learn new features, validate them and share them with you :-)
This tutorial is made in a test environment, for pleasure and not to earn money. It is a non-profit project. It shows that the concept is possible, for a demontration, artistic, or educational purposes, school learning course. Don't test in a real environment in production.
Csharp testing on Windows 11 version 26052 with Dot net 8.0.100 and Godot engine 4.2.1 : signals, os testing in the last article
The Windows 11 Operating System version 23606 was tested in the last article. Check article version 26502 here . Now that operating system is ready, i can test an application.
Csharp testing on Windows 11 version 26052 with Dot net 8.0.100 and Godot engine 4.2.1 : signals, application testing
Now, OS Windows 11 version 23606 is ready, so i can test the middleware apps, frameworks...
Recently, i saw a cool session by Michael Hawker at .NET Conf 2023 about creating a game with C# and a middleware called "Godot engine".
And i said to myself : that’s could be interesting to test this godot engine. it’s an application to test if this new version of the Windows operating system works like a charm. And, with Godo we can create C# programs to do funny things, animations, instead of creating « business » applications less funy.
The idea is simple: you buy a Windows 11 PC at the supermarket, you plug it, and you can create cool things like this :-)
Csharp testing on Windows 11 version 23606 with Dot net 8.0.100 and Godot engine 4.2.1: signals, last articles
Read this article to see how to install Godot engine
Last time i didn’t explain very well how i built the scene with the bouncing ball. I received messages asking me to explain with more details how i’ve done this. So this time i will explain step by step how to build the scene.
Csharp testing on Windows 11 version 26052 with Dot net 8.0.100 and Godot engine 4.2.1: signals, the red ball scene
I launch the Godot engine application by double clicking the Godot_v4.2.1-stable_mono_win64.exe.
The Godot project manager is launching. I clic « new » to create a new project.
By default, the renderer is « mobile » : it’s nice for this C# test godot signal project.
I choose the name « BouncingBallSignal » . Be carefull when choosing the name of your project, beacause last time i included a # , C# , and there was a failure at the compilation, so now i ovoid specials caracters.
I hit the « Create and edit » button.
The Godot game engine user interface launchs. I get the user interface of the godot application engine. The application is ready now. good job!
I see the label: "Create a root node".
There is three categories of nodes: blue for 2D scene, red node for 3D scene, green node for UI user interface.
I click on the red node to create a 3D Scene. I understand that it is my first object who will contain child objects.
So i create a child node by left clicking on the Node3D and +Add Child Node.
I double click « Node3D » and rename it « Node3D Scene RedBall »
I create a child node by calling it "MeshInstance3D".
In this new node, in the inspector, mesh section, i attached a new sphereMesh.
I can edit the new sphere object with the inspector. by opening the surface material override, on the <empty> section i add New and StandardMaterial3D. I click on this new StandardMaterial3D and in the inspector secion albedo, i change his color to red by using HEX ff0000 for example.
I save this scene and i call it « redball ». the « redball.tscn » file appreas in the FileSystem.
Now, i create a New scene : in the scene menu, i clic « new scene ».
I select 3D Node, i double click the Node3D and rename it « Scene Root ».
I create the ground. New child object, MeshInstance3D. And in his inspector mesh section, i choose « PlaneMesh ». I rename it « MeshInstance3D Ground »
MeshInstance3D ground > inspector > scale : x=2 y=2 z=2
MeshInstance3D ground > inspector > transform : y=0
Now, i add in this new scene the ball i created : i drag’n drop it from the FileSystem dock in thisnew scene.
The « Node3D » (redball) appears in the scene. I rename « Node3D » in « RedBall »
I move the ball position y=2m
I click the « play icon » in the upper left corner (Run the project, play the project).
Godot ask me « No main scene has been defined, select one ? (You can change it later in « Project Settings »under the « application » category) ». I click « Select current », and root.tscn.
I see a pop up and a blanck screen, because, there is no camera and no light.
I close this pop up.
In the Root scene, i add a child node, « Camera3D »
I move this « Camera3D » for a translation of Z=8 by dragging the object ad moving it with Shift down.
I move this « Camera3D » for a translation of y=1, in the inspector/Transform.
In the Root scene, i add a child node, « DirectionalLight3D »
I move this « DirectionalLight3D » for a translation of Z=2 by dragging the object ad moving it with Shift down. Or inspector. Rotation X=-45.
Now i’ll show the Camera3D view.
I click the « view » button and select « 2 viewports ». I select the Camera3D node, and in the bottow view, and click the « preview » button.
In the inspector (Camera3D selected) i change the FOV 75 to 30.
I want to add gravity to the ball.
Now i edit the RedBall scene by clicking the little triangle icon in the same line of the RedBall object.
I add a child node to the Node3D RedBall:
-The rigid body, RigiBody3D (to have forces applied to this object)
I add a child node to the RigiBody3D :
-The collider, CollisionShape3D (So that this object can interact with other objects). This CollisionShape3D need to be a child of the RigiBody3D.
In the CollisionShape3D, Inspector, shape, i choose « NewSphereShape3D »
I adjust the NewShpereShape3D to match the MeshInstance3D RedBall object
I go back to the main scene by clicking the « root » in the viewport.
I want to see the hierarchy of the ball scene. So i rightclick on the « Redball » node, and select the « editable children » option.
To enable gravity, the MeshInstance3D node must be a child of the RigidBody3D. We can do that by editing the Redball scene.
I click the « play icon » in the upper left corner (Run the project, play the project).
Now i see that the ball is falling because of the gravity.
The ground needs physics too in order to see the ball bouncing on it.
I add a StaticBody3D to be the parent of the MeshInstance3D ground object (to be static, not be moved by the gravity).
I add the CollisionShape3D as a child of the StaticBody3D.
I choose the shape BoxShape3D of the CollisionShape3D in the inspector, physics material override.
I adjust the Boxshape 3D to match the MeshInstance3D ground object
(transform, position, y=-05m)
I click the « play icon » in the upper left corner (Run the project, play the project).
The ball is stopped by the ground.
Now, i need to make the ground type « bouncy ».
On FileSystem, res://, right click and create new, resource. Select : PhysicsMaterial and i name it bouncy.tres .
On FileSystem, i select bouncy.tres file, and in the inspector, i assign bounce=0.9
I select the groung StaticBody3D and in physics_mateial_oveide i click <empty> and load : bouncy.tres
I click the « play icon » in the upper left corner (Run the project, play the project).
The ball now fall on the ground and bounces a few times and stops.
Now i want to add a signal, so that, each time the Red Sphere touch the ground, it write the message « Boing it bounces ! » in the console.
I will choose to use the signal _on_body_entered() of AREA3D.
I add a child node object Area3D to the RigidBody3D RedBall.
I add a child node object CollisionShape3D to this Area3D object.
I select this Area3D of the RedBall. Right clic, attach script
Language : C#
Path : res://Area3D.cs
Note : the class you wish to attach to your node should have the same name as the .cs file.
->Keep in mind that the class you wish to attach to your node should have the same name as the .cs file. Otherwise, you will get the following error:
"Cannot find class XXX for script res://XXX.cs"
https://docs.godotengine.org/en/stable/tutorials/scripting/c_sharp/c_sharp_basics.html
The script opens in visual studio code. A question comes : « Do you trust the authors of the files in this folder ? » I must trust the author and i click this button.
The Godot engine automatically create the *.sln et the *.csproj , nice!
Now i see this code :
using Godot;
using System;
public partial class Area3D : Godot.Area3D
{
// Called when the node enters the scene tree for the first time.
public override void _Ready()
{
}
// Called every frame. 'delta' is the elapsed time since the previous frame.
public override void _Process(double delta)
{
}
}
Now, the node contains a C# script, so i can add my signal method.
I create the callback method (called Slot) so, when the signal is emitted, the slot method is called.
I add the method « _on_body_entered() » : my C# script looks like that now :
using Godot;
using System;
public partial class Area3D : Godot.Area3D
{
// Called when the node enters the scene tree for the first time.
public override void _Ready()
{
GD.Print("ConsultingIT.fr is starting the simulation");
}
void _on_body_entered(Node root)
{
GD.Print("Boing it bounces!");
}
// Called every frame. 'delta' is the elapsed time since the previous frame.
public override void _Process(double delta)
{
}
}
I add this line to see when the script starts :
GD.Print("ConsultingIT.fr is starting the simulation");
I select RigidBody3D RedBall / Area3D. In Inspector, i switch to node, and select the signals tab.
I right click the body_entered signal and « connect » and this window pop up :
G:\teamviewer\Windows-11-Csharp-godot\signals\Csharp testing on Windows 11 version 23620 with Dot net 8.0.100 and Godot engine 4.2.1 godot engine attach signal body_entered.JPG
I notice the receiver method is « _on_body_entered » ( that’s why i inserted it in my C# script.)
I click « connect »
I run the scene and each time the ball hits the ground, the signal is emited and a line « Boing it bounces ! » arrives in the console.
Csharp testing on Windows 11 version 26052 with Dot net 8.0.100 and Godot engine 4.2.1: add a pause in the game
I need to add a pause before the scene plays.
I try to add a readResult to read a key from the keyboard :
string? readResult;
bool validEntry = false;
Console.WriteLine("Press a key to start the demo");
do
{
readResult = Console.ReadLine();
if (readResult != null)
{
GD.Print("ConsultingIT.fr is starting the simulation");
}
} while (validEntry == false);
I compile, run the scene, and the debug screen freezes…
What’s wrong?
So i decide to ask Copilot « in godot engine how to add a pause before scene rendering »
Csharp testing on Windows 11 version 26052 with Dot net 8.0.100 and Godot engine 4.2.1: asking Copilot
AI-generated code. Review and use! Awesome!
Copilot answers me with a C# script sample
To pause the game, you need to set the pause mode. This is done by calling SceneTree.set_pause(true) with a true argument. Here’s an example of how you can do it in your script:
// In your script (e.g., attached to a Node or a RigidBody3D):
var tree = GetTree();
tree.SetPause(true);
Next, in copilot, i read :
« Remember that pausing the game affects all processing, including rendering. Adjust the pause mode according to your specific requirements. For more details, you can refer to the official Godot documentation on pausing games1. Happy game development! »
So i can browse the official Godot documentation
https://docs.godotengine.org/en/stable/tutorials/scripting/pausing_games.html
I read the better way is to create a menu with a pause/unpause button
In my Root scene i create a new Node : Control
In this Control node, i create a child node : Button.
I rename It Button Pause
In the inspector, i add the text property: Pause
In the signals node, i attach the button_down() signal with the Receiver Method : _on_button_pause_button_down
On the button node, i attach the script ButtonPause.cs
I add the method _on_button_down with
var tree = GetTree();
tree.SetPause(true);
In this Control node, i create a child node : Button.
I rename It Button Play
In the inspector, i add the text property: Play
In the inspector, i add the text property: Transform/Position X=100, and the Node process mode to « When Pause » (Because when the Pause Button is pressed, all nodes are freezed);
In the signals node, i attach the button_down() signal with the Receiver Method : _on_button_play_button_down
On the button node, i attach the script ButtonPlay.cs
I add the method _on_button_down with
var tree = GetTree();
tree.SetPause(true);
Now i want the game be paused as soon as it starts.
In the ButtonPlay.cs i add a tree.Paused=true ;
Done
Csharp testing on Windows 11 version 26052 with Dot net 8.0.100 and Godot engine 4.2.1: resize debug window
i ask Copilot and it answers me that :
To resize the debug window in Godot Engine, follow these steps:
Open your project in the Godot editor.
Go to Project Settings (usually found under the “Scene” menu or by pressing F8).
In the Display section, navigate to Window.
Adjust the Size settings by specifying the desired width and height for the debug screen.
Save your changes.
This will modify the resolution of the debug screen within the IDE without affecting your project layout size. Now you can better match your target resolution while testing your game! 🎮
Default :1152x648
I put 640x480
Csharp testing on Windows 11 version 26052 with Dot net 8.0.100 and Godot engine 4.2.1: signals,done
Done! We can use C# in Godot 4.2.1 on windows 11 version 23606 to create a scene with a signal. A signal is a method called by the godot scene in the C# script when an action is detected. We call that a "callback" pattern like in javascript.
Csharp testing on Windows 11 version 26052 with Dot net 8.0.100 and Godot engine 4.2.1: signals, need help ?
Need help to use godot engine on Windows 11 or write C# code?

Windows Server version 25379 les nouveautés: AD DS et DNS ok
Dans le cadre de la configuration du rôle AD DS, on doit fournir des réponses aux questions:
Installez-vous une nouvelle forêt, une nouvelle arborescence ou un contrôleur de domaine supplémentaire pour un domaine existant ?
La réponse à cette question détermine les informations supplémentaires dont vous pouvez avoir besoin, telles que le nom de domaine parent.
Quel est le nom DNS (Domain Name System) du domaine AD DS ?
Lorsque vous créez le premier contrôleur de domaine pour un domaine, vous devez spécifier le nom de domaine complet (FQDN). Lorsque vous ajoutez un contrôleur de domaine à un
domaine ou une forêt existants, vous utilisez le nom de domaine existant.
Quel niveau choisirez-vous pour le niveau fonctionnel de forêt ?
Le niveau fonctionnel de forêt détermine les fonctionnalités de forêt disponibles ainsi que le système d’exploitation (OS) de contrôleur de domaine pris en charge. Cela définit également le niveau fonctionnel de domaine minimal pour les domaines de la forêt.
Quel niveau choisirez-vous pour le niveau fonctionnel de domaine ?
Le niveau fonctionnel de domaine détermine les fonctionnalités de domaine qui seront disponibles et les systèmes d’exploitation de contrôleur de domaine pris en charge.
Le contrôleur de domaine sera-t-il un serveur DNS ?
Vous pouvez installer le rôle DNS dans le cadre du déploiement du contrôleur de domaine.
Le contrôleur de domaine hébergera-t-il le catalogue global ?
Cette option est activée par défaut.
Le contrôleur de domaine sera-t-il un contrôleur de domaine en lecture seule (RODC) ?
Cette option n’est pas disponible pour le premier contrôleur de domaine d’une forêt.
Quel sera le mot de passe du mode de restauration des services d’annuaire (DSRM) ?
Ce mot de passe est nécessaire pour restaurer des objets de base de données AD DS à partir d’une sauvegarde.
Quel est le nom NetBIOS du domaine AD DS ?
Lorsque vous créez le premier contrôleur de domaine pour un domaine, vous devez spécifier le nom NetBIOS du domaine.
Où seront créés la base de données, les fichiers journaux et les dossiers SYSVOL ?
Par défaut, le dossier de la base de données et des fichiers journaux se trouve dans C:\Windows\NTDS. Par défaut, le dossier SYSVOL se trouve dans C:\Windows\SYSVOL.
Besoin d'aide avec Windows Server ?
Windows Server version 25379 les nouveautés: Conclusion
La création d'une forêt et d'un domaine Active Directory fonctionne bien sur la version 25379
Windows Serveur 2022, oui mais en réalité, c’est la version Vnext 25379.zn_release.230525-1407 comme on le voit marqué en bas à droite
