Types

type Chunk

type Chunk struct {
	X, Z int
	// contains filtered or unexported fields
}

func NewChunk

func NewChunk(x, z int) *Chunk

func (*Chunk) GetBlockLight

func (c *Chunk) GetBlockLight(x, y, z int) int

func (*Chunk) GetBlockState

func (c *Chunk) GetBlockState(x, y, z int) uint16

func (*Chunk) GetSkyLight

func (c *Chunk) GetSkyLight(x, y, z int) int

func (*Chunk) MakeChunkDataPacket

func (c *Chunk) MakeChunkDataPacket(writer *minecraft.Writer)

Write the chunk data into the given writer in the Chunk Data format

NOTE: This does not include block entities! these are managed by the world

so they need to be written by the world as well!

func (*Chunk) MakeUpdateLightPacket

func (c *Chunk) MakeUpdateLightPacket(writer *minecraft.Writer)

TODO: maybe cache this

func (*Chunk) SetBlockLight

func (c *Chunk) SetBlockLight(x, y, z int, light int)

func (*Chunk) SetBlockState

func (c *Chunk) SetBlockState(x, y, z int, state uint16)

func (*Chunk) SetSkyLight

func (c *Chunk) SetSkyLight(x, y, z int, light int)
