{{distinguish|Entity}}
|
||
|
||
A '''block entity''' (also known as a '''tile entity''') is an additional object associated with certain [[block]]s.
|
||
|
||
== Usage ==
|
||
Block entities can store additional information about their block, beyond the finite set of [[block states]] that block may have. For example, all blocks that can store items use a block entity for this purpose.
|
||
Block entities can also tick, running code regularly while loaded, even when not interacted with directly.
|
||
Complex rendering not available to normal [[block model]]s is also achieved with block entities.
|
||
Blocks with block entities can be moved by [[piston]]s {{in|be}}, but not {{in|je}}.
|
||
|
||
== List of block entities ==
|
||
These are the current blocks that hold block entities.

== Render limits ==
|
||
{{Exclusive|java|section=1}}
|
||
|
||
Block entity rendering stops beyond a hard-coded block limit which is modeled after the radius of a sphere. This limit is ''not'' affected by the Render Distance nor the Entity Distance scale in the [[Video Settings]].
|
||
|
||
Some effects related to block entities stop rendering beyond a different number of blocks:
|
||
* The [[beacon]] and [[End Gateway (block)|end gateway]] beams stop rendering beyond 256 blocks {{in|JE}} or 64 blocks {{in|BE}} or when the end gateway is out of frame.
|
||
* The outlines created by a [[structure block]] stop rendering beyond 96 blocks.
|
||
|
||

||
* [[Chunk format#Block entity format|Chunk format § Block entity format]] – describes the save format for block entities
|
||
* [[Entities]], which are all the dynamic, moving objects throughout the ''Minecraft'' world, plus several non-moving objects that resemble blocks.
|
||
* [[Block states]], which are, like block entities, extra pieces of data that further define a block.
