# NBT
|
||||
This package implement the Named Binary Tag format of Minecraft.
|
||||
This package implement the Named Binary Tag format of Minecraft. It supports all formats
|
||||
of NBT including compact arrays for longs.
|
||||
|
||||
# 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 "bytes"
|
||||
import "github.com/Tnze/go-mc/nbt"
|
||||
|
||||
type Compound struct {
|
||||
Name string `nbt:"name"` // Note that if name is private (name), the field will not be used
|
||||
}
|
||||
|
||||
func main() {
|
||||
var out bytes.Buffer
|
||||
banana := Compound{Name: "Bananrama"}
|
||||
_ = nbt.Marshal(&out, banana)
|
||||
|
||||
var rama Compound
|
||||
_ = nbt.Unmarshal(out.Bytes(), &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
|
||||
}
|
||||
```

||||
