Living block types are an internal classification that controls the § Behavior, § Collision, § Interactions (response to interact and hurt), § Movement, and § Fire immunety of the living block.

Almost all of these properties are uniquely defined (each block has only one of each) with the exception of behavior, where the same type can have more than one behavior or none.

Each living block has only one type, and this type is uniquely defined by the ID of the item associated with the living block. Each item in the game can correspond to a maximum of one type. Some types are shared by more than one item.

Blocks whose item does not correspond to a type, receives the type default block or default item.

Types

Bucket type Default item

On Interact: Empty bucket interaction

On hurt: Empty content on upon death

If a property is not defined for a block type, it uses its default value, that is:

  • Behavior: Empty list
  • Collision: Block
  • On interact: Consume item
  • On hurt: Do nothing
  • Movement: Rolling
  • Fire immune: False

Register

The living blocks of an item in the list below always receive the type associated with the item. For other living blocks, it depends. If the item is associated with a block (i.e., it is an instance of BlockItem) and is not in the #block_placers tag, it receives the type default block; otherwise, it receives the type default item.

Behavior

Behavior controls certain actions of living blocks, such as when they will perform and stop performing the action, what happens when they die, and other things.

Below is a summary of the living block behaviors, using the class name in the code[note 1]:


Absorb snow

If the living block don't have 8 layers of snow, passing over a snow increases its layer by one and decreases the block's layer by one (transforming the block into air if it only has one layer). Passing over a snow block transforms it into snow with seven layers. With some additional conditions:

  • The distance from the last absorbed block must be greater than one in some horizontal axis.
    • When the internal data from the living block is loaded, for example when it is summoned or loaded into the world, consider that the last block absorbed was at position 0, 0, 0.
  • The last absorbed block must have been more than 20 ticks away.

Annoying click clack

Within a 10-tick interval, A random number between 0 and 1 is generated:

  • If the number is lass to 0.25 (25%) and the living block is powered, it producing a particle dust{color:16711680,scale:0.5}
    • The particle's position is the same as a lever block in that block and has the same facing and face. Since the living block rarely goes to this same position as the block, the particle ends up appearing in a random place. However, unmoved living floor levers regularly produce particles.
  • If the number is lass to 0.10 (10%) living block changing its powered state.
    • Note that whenever a powered living block changing, it will emit a particle first, and whenever a living block producing a particle, it has a 40% chance of changing its powered status.
