Functions

func ChunkToSave added in v1.18.2 

func ChunkToSave(c *Chunk, dst *save.Chunk) (err error)

ChunkToSave convert level.Chunk to save.Chunk

Types

type BiomesState added in v1.18.2 

type BiomesState = biome.Type

type BitStorage 

type BitStorage struct {
	// contains filtered or unexported fields
}

BitStorage implement the compacted data array used in chunk storage and heightmaps. You can think of this as a []intN whose N is indicated by "bits". For more info, see: https://wiki.vg/Chunk_Format This implementation is compatible with the format since Minecraft 1.16

func NewBitStorage 

func NewBitStorage(bits, length int, data []uint64) (b *BitStorage)

NewBitStorage create a new BitStorage.

The "bits" is the number of bits per value, which can be calculated by math/bits.Len() The "length" is the number of values. The "data" is optional for initializing. It will panic if data != nil && len(data) != calcBitStorageSize(bits, length).

Example (Heightmaps) 
// Create a BitStorage
bs := NewBitStorage(bits.Len(256), 16*16, nil)
// Fill your data
for i := 0; i < 16; i++ {
	for j := 0; j < 16; j++ {
		bs.Set(i*16+j, 0)
	}
}
// Encode as NBT, and this is ready for packet.Marshal
type HeightMaps struct {
	MotionBlocking []uint64 `nbt:"MOTION_BLOCKING"`
}
_ = pk.NBT(HeightMaps{bs.Raw()})

func (*BitStorage) Fix added in v1.19.0

Get gets [i] value.

func (*BitStorage) Len 

func (b *BitStorage) Len() int

Len is the number of stored values.

func (*BitStorage) Raw 

func (b *BitStorage) Raw() []uint64

Raw return the underling array of uint64 for encoding/decoding.

func (*BitStorage) ReadFrom 

func (b *BitStorage) ReadFrom(r io.Reader) (int64, error)

func (*BitStorage) Set 

func (b *BitStorage) Set(i, v int)

Set sets v into [i].

func (*BitStorage) Swap 

func (b *BitStorage) Swap(i, v int) (old int)

Swap sets v into [i], and return the previous [i] value.

func (*BitStorage) WriteTo 

func (b *BitStorage) WriteTo(w io.Writer) (int64, error)
