So I have a crafting recipe that uses water bottles, which are technically a potion with only an NBT tag to separate them from other potions. Is it possible to check for this NBT tag in the new JSON format for making crafting recipes? If so, what's the syntax? I don't really want players to be able to craft the item with any potion...

Here's what my JSON file looks like so far:

 

{
	"type": "minecraft:crafting_shaped",
	"pattern": [
		"iIw",
		"Db ",
		" Bi"
	],
	"key": {
		"i": {
			"item": "minecraft:iron_ingot",
			"data": 0
		},
		"I": {
			"item": "minecraft:iron_block",
			"data": 0
		},
		"w": {
			"item": "minecraft:potion",
			"data": 0,
			"tag": {"Potion":"minecraft:water"} #<------ This is what isn't working, because I don't know the syntax (if at all possible)
		},
		"D": {
			"item": "minecraft:dispenser",
			"data": 0
		},
		"b": {
			"item": "minecraft:bucket",
			"data": 0
		},
		"B": {
			"item": "minecraft:stone_button",
			"data": 0
		}
	},
	"result": {
		"item": "gadgetsngoodies:water_gun",
		"data": 0,
		"count": 1
	}
}

 

Use the minecraft:item_nbt ingredient type. Set the nbt property to the NBT data you want.

 

I don't have any examples of the minecraft:item_nbt ingredient type, but you can see an example of a recipe output with NBT (which uses the same properties) here.

Ah, thanks very much!
