The signaling server should not be pasted into godot but into vscode or anything and the run it on a raspberry pi or anything, the project don't work without it.
I have used vs code in the past for unity development, but are you implying that the game I make must be set up with C# in mind? how do I connect the scripts so that the multiplayer works? (does it matter what I name the vs code project or anything, or does the code just need to be somewhere?)
It's not C# its javascript, which vscode handles very well too ;) And the javascript just starts a server so just make it keep running and then run your cool project with the signaling code and the web rtc stuff and you'll get a multiplayer connection after a second or two.
