Block ID Registry

Every block (called a “Tile” internally) is registered in Tile::staticCtor() in Minecraft.World/Tile.cpp. The ID passed to each tile constructor is the numeric block ID used on the wire and in save data.

The LCEMP repo covers blocks up to ID 171 (TU12-era). The MinecraftConsoles repo goes further, adding blocks up through ID 173 (TU19-era content like stained clay, hoppers, and hay blocks).

Note

In the LCEMP source, IDs 137-138, 146-152, 154, 157-170 are unassigned. IDs 34 and 36 (pistonExtension, pistonMovingPiece) are technical blocks with no collectible item form.

Additional Blocks (MinecraftConsoles)

The MinecraftConsoles repo has a newer codebase (roughly TU19). It renames some fields and adds a bunch of new blocks. Here is every block that was added or changed compared to the LCEMP source.

Renamed Fields

Several fields got renamed between the two repos:

ID	LCEMP Field	MinecraftConsoles Field	Notes
1	rock	stone	Same StoneTile class
4	stoneBrick	cobblestone	Texture changed to cobblestone
25	musicBlock	noteblock	Class changed to NoteBlockTile (was MusicTile)
35	cloth	wool	Class changed to ColoredTile (was ClothTile)
48	mossStone	mossyCobblestone	Texture changed to cobblestone_mossy
59	crops	wheat	Same CropTile class
75	notGate_off	redstoneTorch_off	Same NotGateTile class
76	notGate_on	redstoneTorch_on	Same NotGateTile class

173	coalBlock	Tile	coal_block

Note

The RailTile class was refactored into BaseRailTile in MinecraftConsoles. RailTile (ID 66) still exists but now extends BaseRailTile, and PoweredRailTile replaces the old RailTile(id, true) pattern for powered/activator rails. DetectorRailTile also extends BaseRailTile instead of RailTile.

The EntityTile base class was supplemented with BaseEntityTile. New tile entity blocks like BeaconTile, HopperTile, DaylightDetectorTile, NoteBlockTile, and EnchantmentTableTile extend BaseEntityTile instead of the older EntityTile.

Data Values

Several blocks use auxiliary data bits to store sub-types:

Block	Data Meaning
sapling (6)	0 = Oak, 1 = Spruce, 2 = Birch, 3 = Jungle
treeTrunk (17)	0 = Oak, 1 = Spruce, 2 = Birch, 3 = Jungle
leaves (18)	Low 2 bits: 0 = Oak, 1 = Spruce, 2 = Birch, 3 = Jungle
sandStone (24)	0 = Normal, 1 = Chiseled, 2 = Smooth
cloth/wool (35)	0 = White … 15 = Black (standard wool colors)
stoneSlab / stoneSlabHalf (43/44)	0 = Stone, 1 = Sandstone, 2 = Wooden, 3 = Cobblestone, 4 = Brick, 5 = Stone Brick
woodSlab / woodSlabHalf (125/126)	0 = Oak, 1 = Spruce, 2 = Birch, 3 = Jungle
wood (5)	0 = Oak, 1 = Spruce, 2 = Birch, 3 = Jungle
stoneBrickSmooth/stoneBrick (98)	0 = Normal, 1 = Mossy, 2 = Cracked, 3 = Chiseled
monsterStoneEgg (97)	0 = Stone, 1 = Cobblestone, 2 = Stone Brick
cobbleWall (139)	0 = Cobblestone, 1 = Mossy Cobblestone
