Resurrection!

New page

This is a resurrection of the original page at [http://www.minecraft.net/docs/levelformat.jsp http://www.minecraft.net/docs/levelformat.jsp].

==Level File Format==
Minecraft levels uses a custom tagged binary format I've chosen to call Named Binary Tag (or NBT for short).<br>
To be able to load and save Minecraft levels in a future proof way, please implement support for NBT.<br>
You can read the specification [[NBT|here]] (includes an example of how to parse the format).

Minecraft level files have the file extension <tt>mclevel</tt>, and Internet media type ("MIME type") <tt>application/x-minecraft-level</tt>

Here's the layout of a minecraft level NBT file:<br>
([http://www.minecraft.net/docs/test.mclevel Download sample file]) ''(dead)''

<pre>
TAG_Compound "MinecraftLevel"
{
TAG_Compound "Environment"
{
TAG_Short "SurroundingGroundHeight"// Height of surrounding ground (in blocks)
TAG_Byte "SurroundingGroundType" // Block ID of surrounding ground
TAG_Short "SurroundingWaterHeight" // Height of surrounding water (in blocks)
TAG_Byte "SurroundingWaterType" // Block ID of surrounding water
TAG_Short "CloudHeight" // Height of the cloud layer (in blocks)
TAG_Int "CloudColor" // Hexadecimal value for the color of the clouds
TAG_Int "SkyColor" // Hexadecimal value for the color of the sky
TAG_Int "FogColor" // Hexadecimal value for the color of the fog
TAG_Byte "SkyBrightness" // The brightness of the sky, from 0 to 100
}

TAG_List "Entities"
{
TAG_Compound
{
// One of these per entity on the map.
// These can change a lot, and are undocumented.
// Feel free to play around with them, though.
// The most interesting one might be the one with ID "LocalPlayer", which contains the player inventory
}
}

TAG_Compound "Map"
{
// To access a specific block from either byte array, use the following algorithm:
// Index = x + (y * Depth + z) * Width

TAG_Short "Width" // Width of the level (along X)
TAG_Short "Height" // Height of the level (along Y)
TAG_Short "Length" // Length of the level (along Z)
TAG_Byte_Array "Blocks" // An array of Length*Height*Width bytes specifying the block types
TAG_Byte_Array "Data" // An array of Length*Height*Width bytes with data for each blocks

TAG_List "Spawn" // Default spawn position
{
TAG_Short x // These values are multiplied by 32 before being saved
TAG_Short y // That means that the actual values are x/32.0, y/32.0, z/32.0
TAG_Short z
}
}

TAG_Compound "About"
{
TAG_String "Name" // Level name
TAG_String "Author" // Name of the player who made the level
TAG_Long "CreatedOn" // Timestamp when the level was first created
}
}
</pre>

And here are the currently implemented block ids:
<pre>
0: Air
1: Rock
2: Grass
3: Dirt
4: Cobblestone
5: Wood
6: Sapling
7: Adminium

20: Glass
21 through 36: Cloth tiles of various colors
37: Flower
38: Rose
39: Red mushroom

41: Gold
42: Iron (honestly!)
43: Double stone slab

45: Red brick tile
46: TNT
47: Bookshelf
48: Moss covered cobblestone
49: Obsidian
