What is Structure Void in Minecraft?

A structure void is a unique block in Minecraft that is invisible, allowing existing blocks to remain unchanged instead of being overridden when using the structure block to load a structure. It is not to be confused with the structure block, which is a block that can save and load structures, allowing players to move them around in the game world.

Structure voids are not readily available in the game's creative inventory, but they can be obtained using various commands, such as the /setblock, /fill, or /give commands. In Java Edition, they are available in the creative inventory if cheats are enabled.

Structure voids can be placed as part of a structure and ignored when the structure file is saved, resulting in the blocks at the location where the structure is placed being maintained and not overridden. For instance, if a player saves a two-block high structure with air at the top and a structure void at the bottom and loads it into a two-block high area of stone, the top block becomes air, but the bottom stays stone.

In Java Edition, structure void blocks have no collision box, but they have a small hitbox. Additionally, they are invisible, but they are displayed as red cubes when "Show invisible blocks" is turned on in Save mode inside a Structure Block. Blocks can replace structure voids, similar to snow and grass. A piston can move a structure void, but the structure void pushed by the piston will turn into air.

In Bedrock Edition, structure void block hitboxes are the same as a full block and appear when held by the player, similar to barriers. Unlike Java Edition, they can support blocks such as signs, torches, rails, and redstone wire. A piston cannot move a structure void. As there is no collision box, entities can pass through structure voids, although liquids cannot.

The structure void block has different data values, depending on the Minecraft version. In Java Edition, the structure void's identifier and translation key are "structure_void" and "block.minecraft.structure_void," respectively. In Bedrock Edition, the structure void's identifier and numeric ID are "structure_void" and "217," respectively.

The structure void block has no sound when broken, placed, or being hit in Java Edition. In Bedrock Edition, it has a sound when broken, placed, being hit, falling on it, walking on it, jumping from it, or falling on it without fall damage.

The structure void block was added to Minecraft in version 1.10, and it was originally intended to be used with the barrier block, but it was eventually created as a separate block. In pre1, structure voids were no longer indestructible, and their blast resistance was reduced to 0 from 18,000,003.

A structure void block is a powerful tool for Minecraft builders as it allows them to create and move structures without affecting the existing blocks in the game world. It can be used to create a variety of buildings, landscapes, and other creations, making it a versatile and essential block for Minecraft players. With its unique properties, the structure void is an excellent addition to Minecraft's building capabilities.

In Bedrock Edition, the structure void has one block state, "structure_void_type," which can take on two values: "void" and "structure air."

In conclusion, structure voids are a unique and useful addition to Minecraft's building capabilities. They allow players to maintain the integrity of existing blocks when loading a structure and provide new opportunities for creativity in building. Understanding the properties and uses of structure voids can help players improve their building skills and make their Minecraft worlds more interesting and functional.
