Recipes & Ingredients
Palladium adds several recipe types and two custom ingredient types on top of the vanilla recipe system. All of them are regular datapack recipes, so they go into the usual folder:
data/<namespace>/recipe/<id>.json
Everything vanilla recipes support works here too: tags in ingredients, NeoForge conditions, overriding recipes from other packs by using the same file path, and so on.
Tailoring Recipes
palladium:item_tailoring
Used by the Tailoring Bench. A tailoring recipe consumes ingredients straight from the player's inventory (no crafting grid), damages the tool in the bench's tool slot, and produces up to four armor pieces at once.
| Field | Type | Required | Fallback | Description |
|---|---|---|---|---|
title | Text Component | Yes | / | Name shown in the recipe list. Plain strings work, as do translatable components. |
results | Object | Yes | / | Map of armor slot (helmet, chestplate, leggings, boots) to the resulting item stack. You can fill any subset of the four slots. |
ingredients | List | Yes | / | The materials taken from the player's inventory. Each entry is a sized ingredient. A single entry can also be given directly without the surrounding list. |
tool | Ingredient | Yes | / | What counts as a valid tool in the bench's tool slot. The tool takes 1 damage per produced piece. |
tool_icon | ID | No | / | Sprite drawn in the empty tool slot as a hint, e.g. palladium:container/slot/shears. |
category | ID | No | / | Groups recipes in the recipe list under a shared headline. The headline text comes from the lang key palladium.tailoring_recipe.category.<namespace>.<path>. |
requires_unlocking | Boolean | No | true | If true, the recipe only shows up once the player has it unlocked in their recipe book (via advancements or /recipe give). Set to false for recipes that should always be available. |
show_notification | Boolean | No | true | Whether unlocking the recipe shows the vanilla toast. |
Sized Ingredients
An ingredient plus an amount:
{
"ingredient": "minecraft:iron_ingot",
"count": 24
}
count defaults to 1 and can be higher than a stack size; the amount is collected across the whole inventory.
Item Stacks
Wherever a recipe produces an item, you can either write a plain item ID or an object with components:
"minecraft:iron_helmet"
{
"id": "mypack:cool_helmet",
"components": {
"palladium:multiversal_variant": "mypack:cool_armor_classic"
}
}
Item Upgrade Recipes
palladium:item_upgrade
Applied at the vanilla smithing table, in the same template + base + addition layout as netherite upgrades. Instead of producing a fixed item, it installs an item upgrade (an entry of the data/<namespace>/palladium/item_upgrade/ registry) onto the base item, keeping all of its existing data.
| Field | Type | Required | Description |
|---|---|---|---|
template | Ingredient | Yes | The item in the template slot. |
base | Ingredient | Yes | The item receiving the upgrade. |
addition | Ingredient | No | Optional third slot. Leave it out and the slot stays empty. |
upgrade | ID | Yes | The item upgrade to install. |
The recipe automatically refuses to match if the base item already has the upgrade, if the upgrade is not applicable to the item, or if it is incompatible with an already installed upgrade.
Multiversal Iterator Recipes
Both menus of the Multiversal Iterator (the anvil-style menu and the suit stand menu) are fully recipe-driven. They look up all recipes of the palladium:multiversal_iterator recipe type and offer every conversion that matches the inserted extrapolator and item. You can add as many of these recipes as you like; the results of all matching recipes are merged.
palladium:multiversal_variants
The recipe behind the standard variant switching. It has no settings at all:
{
"type": "palladium:multiversal_variants"
}
It offers every item with a palladium:multiversal_category component for conversion into each variant of the extrapolator's universe that covers that category. The result keeps all data of the input item and only swaps the variant component.
Palladium ships this recipe by default as palladium:multiversal_variants. If you want the iterator to only ever use your own concrete recipes, you can disable it by overriding the file with a never-loading recipe:
{
"neoforge:conditions": [
{ "type": "neoforge:false" }
],
"type": "palladium:multiversal_variants"
}
palladium:multiversal_conversion
A concrete conversion: turn a specific input into a specific output in a specific universe.
| Field | Type | Required | Description |
|---|---|---|---|
input | Ingredient | Yes | What can be placed in the iterator (tags and custom ingredients work). |
result | Item Stack | Yes | What comes out. Same format as tailoring results. |
universe | ID | Yes | The extrapolator must be designated to this universe. |
Unlike multiversal_variants, the result is a fresh stack built from the recipe. It does not copy any data from the input.
In the suit stand menu, all equipped items matching the input are converted together on a single page.
Ingredient Types
Palladium registers two custom ingredient types. They work anywhere an Ingredient is accepted, in Palladium recipes as well as vanilla crafting, smelting, smithing and recipes from other mods.
palladium:universe
Matches any item stack whose current multiversal variant belongs to the given universe.
{
"type": "palladium:universe",
"universe": "mypack:earth-1234"
}
| Field | Type | Required | Description |
|---|---|---|---|
universe | ID | Yes | The universe the item's variant must be from. |
palladium:multiversal_category
Matches any item stack with the given palladium:multiversal_category component.
{
"type": "palladium:multiversal_category",
"category": "mypack:cool_armor_chestplate"
}
| Field | Type | Required | Description |
|---|---|---|---|
category | ID | Yes | The category the item must have. |
Examples
Basic: Tailoring Recipe
Iron armor tailored from 24 iron ingots with any shears, always visible:
{
"type": "palladium:item_tailoring",
"title": "Iron Armor",
"results": {
"helmet": "minecraft:iron_helmet",
"chestplate": "minecraft:iron_chestplate",
"leggings": "minecraft:iron_leggings",
"boots": "minecraft:iron_boots"
},
"ingredients": {
"ingredient": "minecraft:iron_ingot",
"count": 24
},
"tool": "#c:tools/shear",
"tool_icon": "palladium:container/slot/shears",
"requires_unlocking": false
}
Basic: Multiversal Conversion
A stick becomes bread, but only in Earth-12345:
{
"type": "palladium:multiversal_conversion",
"input": "minecraft:stick",
"result": "minecraft:bread",
"universe": "mypack:earth-12345"
}
Advanced: Universe-Exclusive Crafting
Since the ingredients work in vanilla recipe types too, you can gate regular crafting behind variant state. A shapeless recipe that only works with an Earth-1234 variant item:
{
"type": "minecraft:crafting_shapeless",
"ingredients": [
{ "type": "palladium:universe", "universe": "mypack:earth-1234" },
"minecraft:redstone_block"
],
"result": {
"id": "mypack:multiversal_battery"
}
}
