in devast you can use the map editor. Basically this is just build for fun or for a user who has his own private server, build his structure in a map editor and then copy it to his private server. So it will be faster for the owner to build his desired building.
Save[]
When you have built something, you save it by pressing the button "copied to clipboard" (left button). You copied the codes and now you need to paste them somewhere in your computer, for example, in the txt. file.
Load[]
To load your buildings into the map editor, you need to copy the code that you saved into the txt. file and paste it. Click the insert "right" button.
If you are the owner and want to put this building in a private server, then paste this code into the chat
