Structure Void.png

The structure void item is normally unobtainable in survival. The item is obtainable from asynchronous exploits, 22w13oneBlockAtATime, and 23w13a_or_b. The structure void item can be placed in survival to create structure void blocks anywhere in the world.

Obtaining

Word Tearing and Any Falling Block via Asynchronous Threads

From 14w32a (1.8 snapshot) to 17w46a (1.13 snapshot), asynchronous block updates allow for block palette corruption, and this corruption, when combined with the registry palette type, can allow for the creation of any block that can exist, such as structure voids. Asynchronous block updates also allow for usage of the "generic method" to create a falling block entity of any existing block in your world.

These falling blocks may also be used to obtain their respective item, if it exists in item form, such as end portal frames. Blocks such as end gateways cannot be obtained as items with this method, as they have no corresponding item. Falling blocks also allow for the placement of both blocks that cannot normally be placed, either due to operator restrictions (e.g. command blocks) or not having an item form (e.g. end gateways).


22w13oneBlockAtATime Endermen Spawning

Warning: April Fools' 
This feature requires the usage of April Fools' versions, often requiring file renaming or file deletion to load. See the help page for information on loading these versions.

Endermen in the April Fools' version 22w13oneBlockAtATime spawn carrying random blocks. One of these blocks they can spawn with is structure void. There are 902 different blocks that are equally likely for them to spawn with and so there is a 1/902 = 0.11% chance of the enderman spawning with this block specifically. If the enderman spawns holding a generic_item_block (1/902) there's also a 1/1105 chance it will be this block as its block state, but there's only a 0.0001% chance of this occurring.[1]

In the version, the block can be received from the enderman by angering it then letting it attack the player with an open hand. This will cause the block to transfer into the player's hand. Also, if the enderman dies and the falling block launches from the enderman, this can be picked up by the player. The items can be stored in 22w13oneBlockAtATime by switching the block from carrying to the offhand, shift right-clicking onto a donkey/mule with a chest, and then swapping the item into a slot. Additionally, the enderman carrying the block can be updated and then killed in a later version to obtain the item.


23w13a_or_b Votes

Warning: April Fools' 
This feature requires the usage of April Fools' versions, often requiring file renaming or file deletion to load. See the help page for information on loading these versions.

The April Fool's snapshot 23w13a_or_b introduces a plethora of ways to obtain every block and item in the game, including structure voids. These include:

  1. The egg_free vote, when applied, will allow chickens to lay any block or item in the game (without NBT). This means all chickens have the chance of laying structure voids.
  2. The fish_anything vote, when applied, will allow any item from the creative menu (not the operator tab, with NBT) to be fished (combine with the buff_fishing vote to greatly increase fishing speed). What this means is that there is a chance that structure voids can be randomly fished.
  3. The give_item vote, when applied, will give every online player a random amount of any block or item in the game (without NBT), meaning that you could have structure voids randomly given to you.
  4. The replace_items vote, when applied, will replace all items in online players' inventories with any block or item in the game (NBT of the original replaced item is preserved). This allows for structure voids with Any NBT.
  5. The replace_loot_drop vote, when applied, will replace all loot drops of a random block or item with any block or item in the game (if the original item that is being dropped has NBT, it will be preserved). This is also another method for structure voids with Any NBT.
  6. The replace_recipe_output vote, when applied, will replace all recipes for the given item with any block or item in the game (NBT is preserved if the original output item is supposed to have NBT.) This is yet another method for structure voids with Any NBT.
  7. The villager_gem vote, when applied, will replace all emeralds in all loaded villager's trades with any block or item in the game (without NBT). This means that you can get a villager that trades structure voids, allowing for infinite amounts of structure voids.
  8. The basalt_gen_replace, cobblestone_gen_replace, obsidian_gen_replace, and stone_gen_replace votes, when applied, replace the block of their respective fluid interaction with any block in the game, allowing for blocks in invalid positions and the placement of operator-only blocks such as the Command Block.
