Ingredients¶

Basic Usage¶

The data property of each ingredient splits into a require and a deny section.

Like the results, these are JSON objects representing the NBT tag of the item. As always the json data is passed through the JSON Preprocessor.

All properties with their values referenced in require must be present with the exact values on the item.

All properties and values referenced in deny must not be present on the item.

There's also a remainder property which is described here.

Example:

{
    "type": "crafting_shapeless",
    "ingredients": [
        {
            "item": "minecraft:diamond_sword",
            "data": {
                "require": {
                    "Damage": 2
                },
                "deny": {
                    "happy": "yes"
                }
            }
        }
    ],
    ...
}

This would require a diamond sword with damage 2 which seams to be unhappy 😢

Advanced Matching¶

Wildcards¶

If you use an empty string ("") as a value this is a wildcard and will match all possible values. So this means requiring/denying will match if the given property even exists.

Number ranges¶

If you want to apply a recipe if a numeric nbt value is in a specific range, you can do this by using a value of the form "$a..b". Where a is the lower value and b the upper value. You can leave out either of it if you'd like to use infinity at its position.

Example:

"require": {
    "Damage": "$..40"
}

This will match all items with a Damage value of 40 or less.

Potions¶

Potions are annoying to clarify especially when working with brewing recipes. Therefore Nbt Crafting introduces a special shorthand for it.

You can now use potion instead of the item key in all ingredients, remainders and results. An example brewing recipe using this feature could look like this:

{
    "type": "nbtcrafting:brewing",
    "base": {
        "potion": "minecraft:regeneration"
    },
    "ingredient": {
        "item": "minecraft:stick"   
    },
    "result": {
        "potion": "minecraft:swiftness"
    }
}
