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) (*Provider, error)

New creates a new provider reading and writing files 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) LoadDefaultGameMode

func (p *Provider) LoadDefaultGameMode() world.GameMode

func (*Provider) LoadDifficulty

func (p *Provider) LoadDifficulty() world.Difficulty

func (*Provider) LoadEntities

func (p *Provider) LoadEntities(world.ChunkPos) ([]world.Entity, 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) SaveDefaultGameMode

func (p *Provider) SaveDefaultGameMode(mode world.GameMode)

SaveDefaultGameMode changes the default game mode in the level.dat.

func (*Provider) SaveDifficulty

func (p *Provider) SaveDifficulty(d world.Difficulty)

SaveDifficulty saves the difficulty passed to the level.dat.

func (*Provider) SaveEntities

func (p *Provider) SaveEntities(world.ChunkPos, []world.Entity) error

SaveEntities saves all entities to the chunk position passed.

func (*Provider) SaveSettings

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