# NBT [](https://pkg.go.dev/github.com/Tnze/go-mc/nbt)
|
|
|
|
This package implement the [Named Binary Tag](https://wiki.vg/NBT) format of Minecraft.
|
|
|
|
The API is very similar to the standard library `encoding/json`. If you (high probability) have used that, it is easy to
|
|
use this.
|
|
|
|
## Basic Usage
|
|
|
|
For the following NBT tag:
|
|
|
|
```
|
|
TAG_Compound("hello world") {
|
|
TAG_String("name"): "Bananrama"
|
|
}
|
|
```
|
|
|
|
To read and write would look like:
|
|
|
|
```go
|
|
package main
|
|
|
|
import "github.com/Tnze/go-mc/nbt"
|
|
|
|
type Compound struct {
|
|
Name string `nbt:"name"` // The field must be started with the capital letter
|
|
}
|
|
|
|
func main() {
|
|
banana := Compound{Name: "Bananrama"}
|
|
data, _ := nbt.Marshal(banana)
|
|
|
|
var rama Compound
|
|
_ = nbt.Unmarshal(data, &rama)
|
|
}
|
|
```
|
|
|
|
## Struct field tags
|
|
|
|
There are two tags supported:
|
|
|
|
- nbt
|
|
- nbt_type
|
|
|
|
The `nbt` tag is used to change the name of the NBT Tag field, whereas the `nbt_type`
|
|
tag is used to enforce a certain NBT Tag type when it is ambiguous.
|
|
|
|
For example:
|
|
|
|
```go
|
|
type Compound struct {
|
|
LongArray []int64
|
|
LongList []int64 `nbt_type:"list"` // forces a long list instead of a long array
|
|
}
|
|
```
|
|
|
|
## Stringified NBT
|
|
|
|
You can transform SNBT string into binary NBT by using go-mc, which could be useful when parsing command, but the
|
|
reverse conversion is not supported at the moment.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"bytes"
|
|
"github.com/Tnze/go-mc/nbt"
|
|
)
|
|
|
|
func main() {
|
|
var buf bytes.Buffer
|
|
e := nbt.NewEncoder(&buf)
|
|
err := e.WriteSNBT(`{Tnze: 1, 'sp ace': [I;1,2,3]}`)
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
}
|
|
``` |
