NBT

Data Type

A string or object that defines a named binary tag (NBT) for storing arbitrary data. It consists of key-value pairs (the key being the name of the tag) separated by a comma.

Note

See Minecraft Wiki: NBT format for more information about named binary tags (NBTs).

Examples

"nbt": "{example: {is_special: true, numbers: [100, 3, -56]}}"

This example defines an object NBT that contains an object NBT named example. The example object NBT then contains two NBTs: is_special, which is a boolean that will be converted into a byte NBT (1b), and numbers, which is an integer array NBT.

"nbt": {
    "example": {
        "is_special": true,
        "numbers": [
            100,
            3,
            -56
        ]
    }
}

This is the same example as above, but formatted as an actual object.
