The Named Binary Tag (also known as NBT) is a very simple file format that use binary tags to store data. This file format was created by Markus Persson for storing game data MineCraft. Unfortunately, the NBT format is present in several compression formats: Compressed with GZIP. Compressed with ZLIB.
Who made NBT?
Markus
There are two defacto example files used for testing your implementation ( test. nbt & bigtest. nbt ), originally provided by Markus.
What is a TAG_Compound?
Named Binary Tag specification. NBT (Named Binary Tag) is a tag based binary format designed to carry large amounts of binary data with smaller amounts of additional data. An NBT file consists of a single GZIPped Named Tag of type TAG_Compound. A Named Tag has the following format: byte tagType.
How do I use NBT tags?
NBT tags are used in game commands such as: /summon, /data, /give, /fill, /setblock. The NBT tag is always surrounded in {} such as {NoAI:1}. If there is more than one NBT tag used in a command, the NBT tags are separated by a comma such as {NoAI:1, IsBaby:1}. Each entity (or mob) has its own unique set of NBT tags.
How do I separate NBT tags?
NBT tags are used in game commands such as: /summon, /data, /give, /fill, /setblock. The NBT tag is always surrounded in {} such as {NoAI:1}. If there is more than one NBT tag used in a command, the NBT tags are separated by a comma such as {NoAI:1, IsBaby:1}.
Which is the first tag in a NBT file?
First of all, first tag in an NBT file can sometimes be a TAG_List instead of a TAG_Compound. Additionally, NBT data is encoded in one of two different formats, a little-endian version intended for writing to disk, and a VarInt version intended for transport over the network.
What does NBT stand for in Minecraft?
An NBT file is a zipped Compound tag, with the name and tag ID included. The file in the zip must contain the Compound tag that it is as the first bytes. Some of the files utilized by Minecraft may be uncompressed, but in most cases, the files follow Notch’s original specification and are compressed with GZip.
How is the binary tag format used in Minecraft?
The Named Binary Tag ( NBT) format is used by Minecraft for the various files in which it saves data. The format is described by Notch in a brief specification. The format is designed to store data in a tree structure made up of various tags. All tags have an ID and a name.
How is the NBT format different from JSON?
This format is referred to as SNBT, short for stringified NBT. It is different from the JSON format; hence, any JSON used in NBT, such as raw JSON text, must be enclosed within a string tag. A tag is an individual part of the data tree.
