I have been trying to make a custom codex that will be purchasable at the Terramart, but the codex isn't at the Terramart and I can't seem to spawn it in, so I don't think I have even implemented it into the game. What is wrong with my code? farmguide-codex.codex File Code: { "id" : "farmguide-codex", "title" : "Encyclopedia Plantae", "description" : "A guide to plants across the universe and where to find them. Published by BC Corp.", "icon" : "farmguide.png", "contentPages" : [ "Enyclopedia Plantae A guide to plants across the universe and where to find them. Published by BC Corp", "Table Of Contents Page 1 - Tree Fruits", "Tree Fruits Apples - Lush Planets Green Apples - Lush Planets" ], "itemConfig" : { "rarity" : "Common", "price" : 25 } } terramart.object.patch File Code: [ { "op" : "add", "path" : "/interactData/items/-", "value" : {"item" : "farmguide-codex"} } ] EDIT: I have tried looking at other mods and guides but I have found nothing yet. .codexitems are nonexistent, so how do I make the game register the codex as an item?
