Fedora 35 : Roblox Player and Roblox Studio with Grapejuice.

In today's tutorial, I will show you how to install and play Roblox on the Linux Fedora 35 distribution using Grapejuice software.

The Grapejuice software installs protocol handlers to open games from the Roblox website and file handlers to open place files. It also provides a management interface for installing and launching Roblox.

For this, you will need to have a computer with the necessary hardware requirements for this online game.

I tested it on the old HP Compaq 6710b laptop on which I installed Fedora version 35 and it worked very hard.

Here are the Linux commands I used to install.

[mythcat@fedora ~]$ git clone https://gitlab.com/brinkervii/grapejuice

Fedora 33 : Create a simple GUI Button on Unity 3D.

It is very useful to create applications in the Fedora 33 Linux distribution with the Unity 3D game engine.

In today's tutorial, I will show you how to build the simplest GUI with C# and a dynamic button.

To create a button dynamically you need to use GUI.Button.

Open Unity 3D new project in your Fedora 33 distro.

Add a new Game Object by right click and select Create Empty.

Select Game Object use Add Component to add a New script and name it create_button.

Open it and add this source code:

using UnityEngine;
using UnityEngine.UI;
using System.Collections;
 
public class create_button : MonoBehaviour {
   
    
    void OnGUI() 
        {    
            if (GUI.Button(new Rect(10, 10, 300, 20), "Test - Dynamically button")) 
            {    
                Debug.Log("Test button");
            }
            
        }
}

If you run the Unity project you will see a basic Unity 3D button, see the next image:

Fedora 33 : Create a simple AvaloniaUI window.

This tutorial is about Avalonia UI.

Avalonia is a cross-platform XAML-based UI framework providing a flexible styling system and supporting a wide range of Operating Systems such as Windows via .NET Framework and .NET Core, Linux via Xorg, macOS.

I install avalonia dotnet templates from here:

[mythcat@desk CSharpProjects]$ git clone https://github.com/AvaloniaUI/avalonia-dotnet-templates --recursive

[mythcat@desk CSharpProjects]$ dotnet new --install avalonia-dotnet-templates 
...

Create a default window example with AvaloniaUI:

[mythcat@desk CSharpProjects]$ dotnet new avalonia.app -o MyAppAvalonia
The template "Avalonia .NET Core App" was created successfully.
[mythcat@desk CSharpProjects]$ cd MyAppAvalonia/
[mythcat@desk MyAppAvalonia]$ dotnet add package Avalonia

[mythcat@desk MyAppAvalonia]$ dotnet add package Avalonia.Desktop
...
[mythcat@desk MyAppAvalonia]$ ls

The last step is the run:

This will open a window build with AvaloniaUI.

Fedora 33 : Build and publish with .NET Core SDK .

In this tutorial I will show you how can use .NET Core SDK to build and run a simple MyGame001 application from the last tutorial.
Let's go to the project and get some infos:

[mythcat@desk ~]$ cd CSharpProjects/
[mythcat@desk CSharpProjects]$ cd MyGame001/
[mythcat@desk MyGame001]$ dotnet --info

  Microsoft.NETCore.App 3.1.9 [/usr/lib64/dotnet/shared/Microsoft.NETCore.App]

To install additional .NET Core runtimes or SDKs:
  https://aka.ms/dotnet-download

The next command will create MyGame001.dll.

[mythcat@desk MyGame001]$ dotnet publish --configuration Release --runtime fedora.33-x64 --self-contained false

  MyGame001 -> /home/mythcat/CSharpProjects/MyGame001/bin/Release/netcoreapp3.1/fedora.33-x64/publish/

Now you can run it with dotnet command:

[mythcat@desk MyGame001]$ dotnet /home/mythcat/CSharpProjects/MyGame001/bin/Release/netcoreapp3.1/fedora.33-x64/MyGame001.dll

You can simply run it like an Linux application:

Extension 'ms-dotnettools.csharp' is already installed.

The next step is to create new MonoGame projects:

[mythcat@desk ~]$ cd CSharpProjects/
[mythcat@desk CSharpProjects]$ dotnet new mgdesktopgl -o MyGame001
The template "MonoGame Cross-Platform Desktop Application (OpenGL)" was created successfully.

An update for template pack MonoGame.Templates.CSharp::3.8.0.1641 is available.
    install command: dotnet new -i MonoGame.Templates.CSharp::3.8.0.1641 

I run the default template and working well:

[mythcat@desk CSharpProjects]$ cd MyGame001
[mythcat@desk MyGame001]$ ls
app.manifest  Content  Game1.cs  Icon.bmp  Icon.ico  MyGame001.csproj  Program.cs
[mythcat@desk MyGame001]$ dotnet run Program.cs 

The default source code from Program.cs file is this:

using System;

namespace MyGame001
{
    public static class Program
    {
        [STAThread]
        static void Main()
        {
            using (var game = new Game1())
                game.Run();
        }
    }

Fedora 31 : Install Unity 3D on Fedora Linux.

If you want to install the Unity 3D software on Fedora 31 Linux distro then you can read my tutorial from this webpage.
To run Unity software you need to have one good hardware.
This install require to upload the license file even you use a free or pro license.

Fedora 28 : Strife another golang game framework.

Today I tested this 2D game framework named Strife.
You can read more about this from the official website.
The development team tells us:
  "This a work in progress. It provides a very minimal toolset for rendering shapes, images, and text as well as capturing user input."
This game framework uses SDL2 libraries.
Strife is open source and available under the MIT license.
Let's start with installation into Fedora 28 distro.

[root@desk mythcat]# dnf install SDL2-devel.x86_64
[root@desk mythcat]# dnf install SDL2_ttf-devel.x86_64 
[root@desk mythcat]# dnf install SDL2_image-devel.x86_64 
[mythcat@desk ~]$ go get github.com/felixangell/strife
[mythcat@desk ~]$ cd $GOPATH/src/github.com/felixangell/strife

I test one example from installation folder with particles:

[mythcat@desk strife]$ cd example/particles
[mythcat@desk particles]$ go run particles.go

Fedora 28 : Godot example with linux .

Today I tested a simple example with the game engine named Godot version 3.0.6.
It was created on a Windows 8.1 operating system and exported as a linux application.
I moved the two files to the Fedora 28 operating system.

Fedora 27 : load81 simple lua game engine .

Today I tested something simple with Fedora 27 and scheduling in.
This is a SDL based Lua programming environment for children called load81.

The author teel us:

The name Load81 originates from the fact that in popular Commodore home computers the command LOAD "*",8,1 would load the first program on the disk starting from the file-specified memory location.

Load81 is written in ANSI C and uses SDL and SDL_gfx and SDL_image libraries.
I installed all these libraries and everything worked very well.
Once taken from github with clones I tested the examples in the examples folder and worked well from the first time.
The examples folder come with simple examples and some simple games.
Create your lua script and use this command to run it:

./load81 example.lua

All running scripts require a graphical display account.
They worked very well on my normal account and I got a run-time error on my root account.
From examples, I took the triangles.lua script to illustrate how this game engine looks and works.

function setup()
    background(0,0,0);
end

function draw()
    fill(math.random(255),math.random(255),math.random(255),math.random())
    triangle(math.random(WIDTH),math.random(HEIGHT),
             math.random(WIDTH),math.random(HEIGHT),
             math.random(WIDTH),math.random(HEIGHT))
end

This is screenshot of triangles.lua script:

News: Godot - This new game engine working with Linux .

The last version of Godot Engine Reaches 1.0 come with new features:

• working simple, flexible and feature-rich editor, with tools under multi-platform editor: Linux, Windows and OSX;
• the game result work for your multi-platform: iOS, Android, Desktop Platforms: Windows, OSX, Linux, Web Platforms: PNaCL and consoles: PlayStation 3 and PlayStation Vita (only with a license from Sony); 
• 2D and 3D game development;
• GUI library for UI Game Interfaces;
• A python-based scripting language, designed to make games with C++ API to optimize parts of the game or extend any part of the engine;
• you can animate 2D or 3D. - simulate 2D and 3D physics engines;

First look: I run it, working well.
You need to make some settings to export the game.
Working with .obj to import objects.
Not working with tff fonts.
Seam to be a lite dizzy, but I saw some good youtube tutorials.

download the templates for exporting, see the next image:

and export your game ...
I use Linux and great I have the .bin file.
I don't test it under Linux OS.
