JEI
CraftTweaker comes with support for JustEnoughItems (JEI). You can add or hide items or fluids in JEI or add a Descriptions page for them.
Remove
You can either just remove the item from JEI or remove it and all of it’s crafting table recipes.
//hide(IItemStack item);mods.jei.JEI.hide(<minecraft:diamond>);
//hide(ILiquidStack item);mods.jei.JEI.hide(<liquid:water>);mods.jei.JEI.hide(<fluid:lava>);
//removeAndHide(IIngredient output, @optional boolean NBT-Match)mods.jei.JEI.removeAndHide(<minecraft:iron_leggings>);mods.jei.JEI.removeAndHide(<ore:planks>, false);Hide Categories
You can use this to hide entire JEI Categories (e.g. crafting recipes, furnace recipes, machine X recipes, …).
It accepts the category as string, you can get all registered categories by running /ct jeiCategories ingame.
//hideCategory(category)mods.jei.JEI.hideCategory("minecraft.smelting");Add Item
You can also add an IItemStack to JEI to add Items that weren’t added or to add an item with NBT-Tag to JEI
//addItem(item);mods.jei.JEI.addItem(<minecraft:stone>.withTag({display:{Name: "Pickle",Lore:["What once was stone", "Is stone no more"]}}));Add Description
A JEI Description is an extra page shown when looking up an ingredient’s recipe/usages in JEI which contains information on that ingredient.
You can add a JEI Description to an IItemStack, an IItemStack[], an ILiquidStack or an IOreDictEntry.
If your strings are too long to be written to one line (or page) it will automatically create line/page breaks.
Each string parameter will have at least one line and wrap around the end of the window if too long.
//addDescription(IItemStack item, string... desc);mods.jei.JEI.addDescription(<minecraft:iron_ingot>,"TEST");
//addDescription(IItemStack[] item, string... desc);mods.jei.JEI.addDescription([<minecraft:music_disc>, <minecraft:music_disc>],["Never","Gonna","Give","You","Up","Never","Gonna","Let","You","Down"]);
//addDescription(IOreDictEntry dict, string... desc);mods.jei.JEI.addDescription(<ore:ingotIron>, "You can use these to create things", "", "things like Armor","","","Yes...","That as well...");
//addDescription(ILiquidStack stack, string... desc);mods.jei.JEI.addDescription(<liquid:lava>, ["LAVA"]);The desc parameter is a varArg, which means you can either give one string[] containing all description strings or many single strings, whatever you prefer. Just don’t mix them!
