I'd like to make a Godot software to make static websites.
First, is it possible to use FTP in a Godot software ?
P.S. I'd like to use the same system for my games and my other projects :)
It is not possible, I think.
But you can send network request and write a separate server app for handling these requests.
Well, for this I'm going to use Python, I think !!! (I don't know how to do this for now !)
You can get the python plugin for Godot and use that?
It's possible. You can send packets in Godot, but then you would have to write a whole FTP client from scratch. More likely you can create a plugin, which includes an FTP library (for example, one written in C or C++) and then call functions from there.
