Types

type Provider

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

Provider implements a world provider for the Minecraft world format, which is based on a leveldb database.

func New

func New(dir string, d world.Dimension) (*Provider, error)

New creates a new provider reading and writing from/to files under the path passed. If a world is present at the path, New will parse its data and initialise the world with it. If the data cannot be parsed, an error is returned.

func (*Provider) Close

func (p *Provider) Close() error

Close closes the provider, saving any file that might need to be saved, such as the level.dat.

func (*Provider) LoadBlockNBT

func (p *Provider) LoadBlockNBT(position world.ChunkPos) ([]map[string]interface{}, error)

LoadBlockNBT loads all block entities from the chunk position passed.

func (*Provider) LoadChunk

func (p *Provider) LoadChunk(position world.ChunkPos) (c *chunk.Chunk, exists bool, err error)

LoadChunk loads a chunk at the position passed from the leveldb database. If it doesn't exist, exists is false. If an error is returned, exists is always assumed to be true.

func (*Provider) LoadEntities

func (p *Provider) LoadEntities(pos world.ChunkPos) ([]world.SaveableEntity, error)

LoadEntities loads all entities from the chunk position passed.

func (*Provider) SaveBlockNBT

func (p *Provider) SaveBlockNBT(position world.ChunkPos, data []map[string]interface{}) error

SaveBlockNBT saves all block NBT data to the chunk position passed.

func (*Provider) SaveChunk

func (p *Provider) SaveChunk(position world.ChunkPos, c *chunk.Chunk) error

SaveChunk saves a chunk at the position passed to the leveldb database. Its version is written as the version in the chunkVersion constant.

func (*Provider) SaveEntities

func (p *Provider) SaveEntities(pos world.ChunkPos, entities []world.SaveableEntity) error

SaveEntities saves all entities to the chunk position passed.

func (*Provider) SaveSettings

func (p *Provider) SaveSettings(s *world.Settings)

SaveSettings saves the world.Settings passed to the level.dat.

func (*Provider) Settings

func (p *Provider) Settings(s *world.Settings)

Settings returns the world.Settings of the world loaded by the Provider.
