This feature is exclusive to Java Edition.
 

In Java Edition 1.13, the change known as "The Flattening" was performed, which 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] The contents of this page serve as a comparison between the identifiers of versions 1.12.2 and 1.13.

Later changes to IDs and display names, e.g. water cauldrons being split from cauldrons in 1.17, are not counted here.

Prior specifications[edit | edit source]

Note block
  • [NBT Compound / JSON Object] Block entity data
    • Tags common to all block entities see Template:Nbt inherit/blockentity/template[show]
    • [Byte] note: Pitch (number of uses).
    • [Byte] powered: 1 or 0 (true/false) - if true, the noteblock is being provided a redstone signal.
Flower pot
  • [NBT Compound / JSON Object] Block entity data
    • Tags common to all block entities see Template:Nbt inherit/blockentity/template[show]
    • [String] 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.
    • [Int] 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.
