After a few requests, here is a tutorial on how to create dedicated servers with Godot Engine. In this tutorial I show how to obtain that through a single Godot project, instead of using one project for server and another project for client.
Note that there is a little bit of the synchronization code to showcase the proposed code architecture in practice, although this part of the tutorial uses my Network Addon .
The dedicated server tutorial can be found here .
Happy forging!
