Fedora 33 : Roblox and Wine.

Because I tried to install this platform, I will show you what works and what doesn't. 

At this moment Roblox Player cannot be run with Wine. 

I tested two ways to run it.

First is the roblox-linux-wrapper and the second is the direct way to install RobloxPlayerLauncher.exe.

The roblox-linux-wrapper works but you will get this error. 

The install process is simple:

[mythcat@desk ~]$ git clone https://github.com/roblox-linux-wrapper/roblox-linux-wrapper.git

[mythcat@desk ~]$ whereis wine
wine: /usr/bin/wine /usr/lib/wine /usr/lib64/wine /usr/share/wine /usr/share/man/man1/wine.1.gz

[mythcat@desk ~]$ roblox-linux-wrapper/rlw
> main: Sourcing /home/mythcat/roblox-linux-wrapper/data/rlw-core.sh
> wineinitialize: sourcing /home/mythcat/.rlw/wine_choice

Another way is to download the EXE file and run it with Wine.

[mythcat@desk ~]$ wget http://setup.rbxcdn.com/RobloxPlayerLauncher.exe
wine RobloxPlayerLauncher.exe 
...

You can try to start a game on browser , select the Roblox Player and will get the same error. A good news is about Roblox Studio, this works very well:

[mythcat@desk ~]$ wget https://setup.rbxcdn.com/RobloxStudioLauncherBeta.exe
[mythcat@desk ~]$ wine RobloxStudioLauncherBeta.exe

My video card NVIDIA Corporation GT218 [GeForce 210] (rev a2) is not very good with this application , but works.

Fedora 33 : The new Wine 6.0.

The new released of Wine 6.0 comes with this intro:

The Wine team is proud to announce that the stable release of Wine 6.0 is now available. This release represents a year of development effort and over 8,300 individual changes. It contains a large number of improvements that are listed in the release notes below. The areas of major changes are:

- Core modules in PE format.

- Vulkan backend for WineD3D.

- DirectShow and Media Foundation support.

- Text console redesign. ...

About Wine:

Wine (originally an acronym for "Wine Is Not an Emulator") is a compatibility layer capable of running Windows applications on several POSIX-compliant operating systems, such as Linux, macOS, BSD. Instead of simulating internal Windows logic like a virtual machine or emulator, Wine translates Windows API calls into POSIX calls on-the-fly, eliminating the performance and memory penalties of other methods and allowing you to cleanly integrate Windows applications into your desktop.

I used the Wine repo to install easily this software:

[root@desk mythcat]# dnf config-manager --add-repo https://dl.winehq.org/wine-builds/fedora/33/winehq.repo

Complete! 

You can build it from source code:

[mythcat@desk ~]$ cd wine-6.0/
[mythcat@desk wine-6.0]$ ls
aclocal.m4  configure.ac   fonts    LICENSE.OLD  nls	   server
ANNOUNCE    COPYING.LIB    include  loader	 po	   tools

Wine uses a virtual C: drive and you need to configure it with this command:

[mythcat@desk ~]$ winecfg
wine: created the configuration directory '/home/mythcat/.wine'
002c:fixme:winediag:LdrInitializeThunk wine-staging 6.0 is a testing version containing experimental patches.
...

This starts a new window where you can set the wine software.

Also, you can locate the virtual C: drive at:

[mythcat@desk ~]$ ls -la .wine/drive_c/

I tested with my favorite old game Dune 2000 from this webpage

Just unzip it and run wine with right-click on DUNE2000.EXE and select Open With and Wine Windows Program Loader.

The game runs it well:

You can read about Fedora Linux distro and Wine software on this official MediaWiki page.

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 : Using the finch chat program.

Finch is a TUI (text user interface) IM client for Linux which uses libpurple.

This is very useful when you want to chat and don't have an environment to install Fedora on.

Finch is built using the ncurses toolkit, which is a library designed especially to built text user interfaces.

This program lets you sign on to Jabber, GoogleTalk, IRC, and other IM networks. 

After this was built the Pidgin application.

Let's install it with the DNF tool:

[root@desk mythcat]# dnf install finch.x86_64
...
Installed:
  finch-2.14.1-2.fc33.x86_64                             libgnt-2.14.0-3.fc33.x86_64                            

Complete!

You can find all information using the man command:

[mythcat@desk ~]$ man finch 

You can run it easy with this command:

[mythcat@desk ~]$ finch

After that, you can see the windows form for your account.

You can see one example with my IRC account:

If not you can select it by pressing the keys: Alt+A and select Accounts.

Use the Tab key and select Modify.

The new window form lets you set your account.

In the next image, you can see some settings for my IRC account.

Another important element is that this interface can be customized using the file named .gntrc.

Open it with your editor, I used vi editor:

[mythcat@desk ~]$ vi ~/.gntrc

I make these changes to use the mouse:

[general]
mouse = 1

Although the manual page says the mouse support is still experimental.

I install the GPM - a cut and paste utility and mouse server for virtual consoles.

[root@desk mythcat]# dnf install gpm.x86_64 
...
[root@desk mythcat]# systemctl status gpm
● gpm.service - Console Mouse manager
     Loaded: loaded (/usr/lib/systemd/system/gpm.service; enabled; vendor prese>

[root@desk mythcat]# systemctl status gpm 
● gpm.service - Console Mouse manager
     Loaded: loaded (/usr/lib/systemd/system/gpm.service; enabled; vendor prese>

Jan 15 15:35:32 desk /usr/sbin/gpm[15314]: gpm is already running as pid 15241

The GPM can be configureted to set your mouse settings.

I restart my Fedora 33 Linux distro and works very well with the mouse.
