Dedicated servers

Hello so it is simple I want to clarify that I do not know anything was Unreal and I wonder if it’s possible with Unreal engine to create a MyServer.exe 4 with a configuration files editable by the host or find in the interior
and that following the launch of MyServer.exe it loads the configuration file
and automatically adds the server in the list of game server

In short Yes, UE4 is open source and you can do anything.

You can check out this tutorial about how to build your own dedicated server.exe in UE4:

Nonetheless, since you know nothing about unreal, it will take you a while to actually learn how to use it, how to make a game, how to make a multiplayer game, and eventually you to make your dedicated server.

It’s doable, and you will have the community to support you.
