Minecraft:Tag (item)

Template:Joke feature Template:Infobox item Tags and Bits are items exclusive to the 23w13a_or_b April Fools' joke snapshot from 2023. They are used to craft in-game representations of NBT tags.

Obtaining

A Minecraft:stonecutter can be used to cut a Minecraft:name tag into either 16 "Name" or 16 "Tag" items. These can be cut into 16 Bit items each.

To be able to proceed from here the nbt_crafting vote must be approved. Bits can be used in a crafting table to craft Left Curly, Right Curly, Left Square, and Right Square.

A Minecraft:crafting table can be used to convert a "Tag" item into a "Byte Tag." The amount of Minecraft:sticks added to the crafting recipe specifies the value of the Byte, as a signed 8-bit value. For example, a "Tag" and a full stack of sticks make a Byte with the value 64b, while 255 sticks result in -1b. Only one of the sticks is consumed. Two Bytes can be crafted into a "Short Tag" (equivalent to 16 bit), two Shorts into an "Int Tag" (equivalent to 32 bit), and two Ints into a "Long Tag" (equivalent to 64 bit). Many other combinations that form either 16, 32, or 64 bit are possible. For example, two Shorts and an Int make a Long. When combining values, their digits are stuck together in the given order, e.g. 1b and 0b make 256s (equivalent to 0100₁₆ in hexadecimal). Undoing any of these crafting actions in e.g. a stonecutter is not possible.

"Float" and "Double Tags" can be crafted by adding one or two Minecraft:boats to any numeric tag. A "String Tag" is crafted with a "Tag" and a piece of Minecraft:string.

"Name" and "String Tags" must be named in an Minecraft:anvil before they can be used. Unnamed Names and Strings always produce a "Sssyntax Error". None of the other tag items can be named.

All these items can be combined in a crafting table to form a short sequence of NBT data, as long as the resulting syntax is valid. For example:

• A pair of Curlies that enclose a named "Name" item and some value, e.g. a Byte, create a "Compound Tag" with the content {Example:0b}.
  • Because of the limited size of the crafting table only 3 name-value pairs can be put between Curlies at a time. Compound Tags of any length can be created by concatenating two or more Compound Tags.
  • An empty pair of Curlies produces an empty Compound Tag with the content {}.
• A pair of Square brackets that enclose any number of values, e.g. 7 Bytes, create a "List Tag" with the content [0b,0b,0b,0b,0b,0b,0b].
  • Because of the limited size of the crafting table only 7 values can be put between Square brackets at a time. List Tags of any length can be created by concatenating two or more List Tags.
  • An empty pair of Square brackets produces an empty List with the content [].
  • "Name" items cannot be used in a List.

The resulting Compound and List Tags can be used as values in other Compound and List Tags, as deeply nested as you want.

Usage

Compound Tags with Minecraft:enchantment data will exhibit the traits of that enchantment.<ref>https://www.reddit.com/r/Minecraft/comments/129xdyl/i_figure_out_how_the_nbtcrafting_in_the_vote/</ref>

Trivia

• This implies that a Minecraft:name tag is 256 bit.
• Compound and list tags are special in so far that the value they show in their Minecraft:tooltip is not merely a property of the item, but their actual NBT data. This is also the reason why naming them is disabled as that would mess up the NBT data.
• The snapshot also contains an unused texture for an Template:ItemLink.

Issues

Issues relating to "Tag" and "Bit" are not maintained on the Minecraft:bug tracker because they're Minecraft:April Fools' jokes, and are therefore not in the newest stable version or snapshot. Issues reported there are closed as "Invalid".
