本页面包含了自1.2.5至今的世界信息。有关Alpha信息，另见Alpha地图格式。

一般信息
世界以一连串区域表示，其中包含了许多纵列和区块。每个区域是32x1x32的纵列，每个纵列是1x16x1的区块，而每个区块是16x16x16的方块。一个纵列的总高度是256。每个区块存储4（或5）个东西——方块ID（8位）、方块元信息（4位）、方块光照（4位）和天空光照（4位）。可选的第五个值为“add”数据，它是要加到方块ID的四位来支持额外的方块ID（不用于原版Minecraft）。方块光照是由如火把和萤石投射的光照，并使用3DFlood Fill算法计算。天空光照是由天空投射的光照，并使用从上而下计算。当透过半透明方块时会降低亮度值直至遇上不透明方块。不透明方块是天空光照拥有非零值的最后一个方块。亮度从0xF（最亮）开始，一直到0x0（最暗）。纵列存储生物群系信息。每1x256x1长方体的方块拥有相同的生物群系值，每个区块（16x16）拥有共256种可能的生物群系值。生物群系以字节存储。

Storage
This section documents the Anvil format for servers.
Maps are stored as a specific directory structure with several NBT files within. For the sake of examples, the world we'll be working with is stored in a folder called "/world".
Directory Structure
- /world/data: Unused
- /world/DIM-1: Nether world
- /world/DIM-1/region: Nether world regions
- /world/DIM1: End world
- /world/DIM1/region: End world regions
- /world/players: Player data
- /world/region: Overworld regions
level.dat
In the root directory is a level.dat file. The structure of that file is this:
- NBTCompound(Data)
- NBTByte(hardcore)
- NBTByte(MapFeatures): Set to 1 if structures are generated, such as villages
- NBTByte(raining): Set to 1 if currently raining
- NBTByte(thundering): Set to 1 if currently thundering (only if there is potential for thunder, not if a thunderbolt is currently in progress)
- NBTInt(GameType)
- NBTInt(generatorVersion): 0 for 1.2.5
- NBTInt(rainTime): The ticks remaining until rain stops?
- NBTInt(SpawnX)
- NBTInt(SpawnY)
- NBTInt(SpawnZ)
- NBTInt(thunderTime)
- NBTInt(version): 19133 for 1.2.5
- NBTLong(LastPlayed)
- NBTLong(RandomSeed)
- NBTLong(SizeOnDisk): Always 0 for 1.2.5
- NBTLong(Time)
- NBTString(generatorName)
- NBTString(LevelName)
[playeruuid].dat
Each player that has ever connected is given a [playeruuid].dat file.
- NBTCompound
- NBTByte(OnGround)
- NBTByte(Sleeping)
- NBTShort(Air)
- NBTShort(AttackTime)
- NBTShort(DeathTime)
- NBTShort(Fire): Ticks until the player is no longer on fire, or zero
- NBTShort(Health)
- NBTShort(HurtTime)
- NBTShort(SleepTimer)
- NBTInt(Dimension)
- NBTInt(foodLevel)
- NBTInt(foodTickTimer)
- NBTInt(playerGameType)
- NBTInt(XpLevel)
- NBTInt(XpTotal)
- NBTFloat(FallDistance)
- NBTFloat(foodExhastionLevel)
- NBTFloat(foodSaturationLevel)
- NBTFloat(XpP)
- NBTCompound(Inventory)
- NBTCompound
- NBTByte(Count)
- NBTByte(Slot)
- NBTShort(Damage): Damage -or- metadata
- NBTShort(id)
- NBTCompound
- NBTList(Motion)
- NBTDouble
- NBTDouble
- NBTDouble
- NBTList(Pos)
- NBTDouble
- NBTDouble
- NBTDouble
- NBTList(Rotation)
- NBTFloat
- NBTFloat
[region].mca
Each region file is named "r.x.z.mca", where x and z are the coordinates. These coordinates are relative to each region. Given column coordinates, divide them by 32 to get the region coordinates.
- NBTCompound
- NBTCompound(Chunk [x,z]): x and z are region column coordinates, not relative to the overall world. The compound name is a misnomer, it actually represents column.
- NBTCompound(Level)
- NBTByte(TerrainPopulated): 1 if this column has been generated
- NBTInt(xPos): In global, world-relative chunk coordinates
- NBTInt(yPos): In global, world-relative chunk coordinates
- NBTLong(LastUpdate): The last time a block changed in this column
- NBTByteArray(Biomes)
- NBTList(Entities)
- NBTCompound
- NBTByte(OnGround)
- NBTShort(Air)
- NBTShort(AttackTime)
- NBTShort(DeathTime)
- NBTShort(Fire)
- NBTShort(Health)
- NBTShort(HurtTime)
- NBTFloat(FallDistance)
- NBTString(id): Example: "Skeleton"
- NBTList(Motion)
- NBTDouble
- NBTDouble
- NBTDouble
- NBTList(Pos)
- NBTDouble
- NBTDouble
- NBTDouble
- NBTList(Rotation)
- NBTFloat
- NBTFloat
- NBTCompound
- NBTList(Sections): Chunks
- NBTCompound
- NBTByte(Y): 0-16
- NBTByteArray(BlockLight)
- NBTByteArray(Blocks)
- NBTByteArray(Data)
- NBTByteArray(SkyLight)
- NBTCompound
- NBTList(TileEntities)
- NBTIntArray(HeightMap)
- NBTCompound(Level)
- NBTCompound(Chunk [x,z]): x and z are region column coordinates, not relative to the overall world. The compound name is a misnomer, it actually represents column.
