Could you link me to the config.ini and language wiki section? Anyway, if it can be controlled through actions, now for example I have an interface in english. My interface has a basic background inactive image which is made by all the verbs + inventory slots. And then the active verbs images. For the italian interface I load background and images directly in the main interface or I create a new one and then use "set interface" in the button where I want to switch language? And with actions part how to load all the text in new language? If possible I would like to avoid scripting...
(I've figured out how to make the whole thing, but it's normal that I have a big list of Unnamed under text section?!)
EDIT:
There is this big problem: I've noticed that adding new elements, like another duplicate of the main interface, all hotspots/items, commands are bound to linked commands in the interface, even if it's a duplicate... so I cannot use 2 interfaces. But I can load only 1 image for active buttons in the interface, so how to load a new one?!
