Java Edition 1.13/Flattening

This feature is exclusive to Java Edition.

1.13 modified the IDs of many blocks, items, biomes, particles, paintings, entities, statistics and sound events, removed numeric IDs, added and removed some block states, and changed NBT tags and display names.^[1] This change is known as "The Flattening". The contents of this page serve as a comparison between the identifiers of versions 1.12.2 and 1.13. This was not done to Bedrock Edition, keeping most Bedrock item IDs the same.

Block and item IDs

Blocks and items that change their ID in any way also affect their statistics.

Killed by entities	`stat.entityKilledBy.<argument>`	`minecraft.killed_by:<namespace>.<entity_id>`	<argument> was the pre-1.11 entity ID Now exists for all entities, not just entities with spawn eggs

NBT data

Damage in the root of the item data removed.
Damage added in the tag tag, only used for durability.
map integer added in the tag tag, for maps.
Base of Shields has the colors in the opposite order for consistency.
ench for enchantments got renamed to Enchantments.
Enchantment Ids in Enchantments and StoredEnchantments now use the string ids.

Entities

Changes to entity format:

CollarColor of Wolves has the colors in the opposite order for consistency.
carried and carriedData of Endermen merged into carriedBlockState.^{[NBT note 1]}
inTile and inData of Arrows and Spectral Arrows merged into inBlockState.^{[NBT note 1]}

Prior specifications

Note Block

Block entity data
- Tags common to all block entities
- note: Pitch (number of uses).
- powered: 1 or 0 (true/false) - if true, the noteblock is being provided a redstone signal.

Flower Pot

Block entity data
- Tags common to all block entities
- Item: The Block ID of the plant in the pot. Known valid blocks are minecraft:sapling (6), minecraft:tallgrass (31), minecraft:deadbush (32), minecraft:yellow_flower (37), minecraft:red_flower (38), minecraft:brown_mushroom (39), minecraft:red_mushroom (40), minecraft:cactus (81). Other block and item IDs may be used, but not all will render. Together with Data, this determines the item dropped by the pot when destroyed.
- Data: The data value to use in conjunction with the above Block ID. For example if Item is 6 (a sapling block), the Data is used to indicate the type of sapling.

↑ ^a ^b ^c ^d ^e This tag will change to a compound format with {Name:"block_id",Properties:{state:"value"}}

Commands

Some commands were changed.

/clear [<data>] argument removed.^{[command note 1]}
/clone [<data>] argument merged with ID and no longer allows metadata.^{[command note 2]}
/execute detect (now /execute if|unless block) [<data>] argument merged with ID and no longer allows metadata.^{[command note 2]}
