Update 2:
Got rid of the issue I was having with the LUA script. I’ve got a working dummy menu now, which for testing purposes printed messages for every possible selection (browse the web, browse files, play a game and shutdown).
Keep in mind that the figures below don’t represent the final mod, for reasons I’ll specify soon.
Here is the “common laptop” item examine menu:
And here is the laptop’s use menu, along with some test message prints on the log (as expected):
As you can see, for now all the menu does is print messages according to the selected option, for testing purposes.
I made the laptop work like a flashlight (off and on version), so that it would only work (and have the tool qualities for researching and so on) when powered on, and it is also only rechargeable through an UPS - which might have been a bad idea - so I might end up just making it into a single version to work like a hotplate instead (consuming charges per use and per recipes).
I’ll keep on working on the LUA to make the menu useable on the side. If I end up making it work as intended, the recipe format will be obsolete. But for now, it seems fair enough.
