It depends on what you're trying to add, check ModDocs.zip if you haven't already
oh thanks! I was stupid enough to read the custom item documentation only without reading mod header documentation so I got confused on where to code and where to put what files and stuff. I’ll now work on the mysterious device :)
(also sorry for not replying I am at so many places online now at once that sometimes I just completely forget the existence of a platform like itch)
forget it my mod crashes the game lol (at least i got to see my mod in the mod page before adding the item that crashes the game)
You could join the Discord server and send the mod, so I could check why it crashes and help
