Fletching recipes

Fletching recipes are datapack JSON files, so a datapack can add new ones or replace the built-in ones without code.

Generator

Fill in the slots and copy the result. Use the buttons to start from a built-in recipe.

Start from:

Save asdata/mypack/recipe/fletching/arrow_from_bone.json

{
  "type": "fletchingrecipe:fletching",
  "top": {
    "ingredient": "minecraft:bone",
    "count": 1
  },
  "middle": {
    "ingredient": "minecraft:stick",
    "count": 1
  },
  "bottom": {
    "ingredient": "minecraft:feather",
    "count": 1
  },
  "output": {
    "id": "minecraft:arrow",
    "count": 4
  }
}

Put it in a datapack and run /reload. A file at the same path as a built-in recipe replaces it.

Where the file goes

my_pack/
├── pack.mcmeta
└── data/
    └── <namespace>/
        └── recipe/
            └── <name>.json

Any namespace and name work. Subfolders are allowed, so data/mypack/recipe/fletching/bone_arrow.json has the id mypack:fletching/bone_arrow.

Put the datapack in the world's datapacks folder and run /reload. Players' JEI updates straight away.

Format

{
  "type": "fletchingrecipe:fletching",
  "top": {
    "ingredient": "minecraft:flint",
    "count": 1
  },
  "middle": {
    "ingredient": "minecraft:stick",
    "count": 1
  },
  "bottom": {
    "ingredient": "minecraft:feather",
    "count": 1
  },
  "output": {
    "id": "minecraft:arrow",
    "count": 8
  }
}

Field	Required	Meaning
type	Yes	Always fletchingrecipe:fletching
top	Yes	Ingredient for the top slot
middle	Yes	Ingredient for the middle slot
bottom	No	Ingredient for the bottom slot. Leave it out and the recipe only matches when the bottom slot is empty.
output	Yes	The item stack the recipe makes

Slot ingredients

Field	Type	Meaning
ingredient	Ingredient	What the slot accepts. See below.
count	Positive integer, optional (default 1)	How many items the slot needs, and how many one craft takes

An ingredient can be written three ways:

One item

"ingredient": "minecraft:feather"

Any of several items

"ingredient": ["minecraft:feather", "minecraft:phantom_membrane"]

Item tag

"ingredient": "#minecraft:planks"

Output

Field	Type	Meaning
id	Item id	The item made
count	Positive integer, optional (default 1)	How many one craft makes
components	Object, optional	Data components on the item, such as a potion

For example, a recipe that makes Arrows of Poison:

"output": {
  "id": "minecraft:tipped_arrow",
  "count": 8,
  "components": {
    "minecraft:potion_contents": {
      "potion": "minecraft:poison"
    }
  }
}

Replacing a built-in recipe

Add a file with the same id to your datapack. The built-in recipes are:

Recipe	File
Arrow	data/fletchingrecipe/recipe/fletching/arrow.json
Spectral arrow	data/fletchingrecipe/recipe/fletching/spectral_arrow.json

Things to know

• Recipes are checked before tipped and explosive arrows. A recipe that matches the same items takes their place.
• If two recipes match the same items, the game picks one of them. Give each recipe a distinct combination.
• Plain ingredients ignore components: "minecraft:lingering_potion" accepts every lingering potion.
• The output is always the same item. It does not copy anything from the ingredients.
