This feature is exclusive to Java Edition, Bedrock Edition and Education Edition.

	“	It's a block for map makers, similar to the command blocks. But this one can [take] a structure that you build in the world, for example a house, and save it. It is then possible to place it in the world multiple times. So it's basically saving templates and then copying them back into the world at any position. The nice feature is that every structure can be rotated or mirrored when it's placed.	„
		— Searge on structure blocks^[1]

Structure blocks are blocks that are used to manually generate structures. They can also be used to save and load structures, alongside structure void blocks.

Obtaining[edit]

Structure blocks and structure voids are available only using the /setblock, /fill, or /give commands. Structure blocks when placed are unbreakable in survival and have the same blast resistance as bedrock. This is similar to the command block.

Usage[edit]

When placed, use the structure block to open the structure block GUI. The GUI opens only if the player is in Creative mode, and has the proper permissions. Once a structure is named, its name appears above the structure block when highlighted, preceded by the block mode (e.g. "Save:House").

Before being placed, the structure block uses a "blank" texture in the inventory, a texture that is not used when on a placed block.

A piston cannot move a structure block, but can move a structure void.

Structures saved only to memory have a higher priority than structures of the same name that were saved to disk. To remove a structure from active memory, players need to quit and reload their current game.

Switching between modes preserves the settings of the structure block wherever possible.

Save[edit]

Save Mode GUI for Java Edition

Save Mode GUI for Bedrock Edition

Save mode allows the player to highlight a structure in the world and save it to a file.

Structure Name: The name of the structure is entered into this text box. Capital letters and special characters are not allowed. Underscores (_) and hyphens (-) are allowed. It has "mystructure:" prefix on default.

Relative Position: Enter the X, Y, and Z values for the structure here, based on the position of the structure block. Sets the origin of the structure outline.; Maximum allowed distance from the structure block is 32‌^{[JE only]}/64‌^{[BE only]} blocks in any direction.

Show invisible blocks: Displays air and structure void blocks as small colored cubes. Red cubes signify structure void, while blue cubes signify air. Off by default.

Structure Size: Enter the X, Y, and Z values to set the distance from the Relative Position coordinates. This sets the opposite corner of the structure, and defines its size.; Maximum structure size is 32×32×32.‌^{[JE only]} or 64x64x64.‌^{[BE only]}; When successful, generates a white outline surrounding the structure.

Detect structure size and position: Automatically calculates the size and position of the structure using a corner block placed on the opposite corner of the structure.; The name of the structure in the save block must match the name within the corner block, or the size calculation fails.

Remove blocks: While saving the structure, doesn't include any blocks within structure.

Include entities: While saving the structure, saves any entities within the structure as well

Save: When all coordinates and a structure name have been entered, press this button to save the structure to a file. The name of the structure is the name of the file.; This process may also be automated with the use of redstone, but saves triggered by redstone are saved only to memory, not to disk.; Structures are saved in .minecraft/saves/(WorldName)/generated/minecraft/structures. ^{[note 1]}

↑ Structures created in versions before Java Edition 1.13 are saved in .minecraft/saves/(WorldName)/structures.

Load[edit]

Load Mode GUI for Java Edition

Load Mode GUI for Bedrock Edition

Load mode‌^{[JE only]} ‌^{[BE only]} allows the player to load and rotate saved structure files.

Structure Name

The path and name of the structure file to load from.

Name is case sensitive; it must match exactly with the name of the saved structure.

This may be a file found in the /data/minecraft/structures/<folder_name> folders in minecraft.jar. To load from a folder, simply type <folder_name>/<structure_name>. The following folders exist:

Relative Position: The X, Y, and Z coordinates of the corner in which to generate the structure, based on the position of the structure block, as long as the coordinates are within -32 and 32‌^{[JE only]}/-64 and 64‌^{[BE only]}.

Show bounding box: Highlights the outline of the structure; on by default.

Structure Integrity and Seed: Removes random blocks that compose the structure based on a user-defined seed.

Lower integrity values result in more blocks being removed. The integrity value must be between 0.0 and 1.0.

Include entities: Include any entities saved in the structure file when loading the structure. Off by default.

Rotation (0, 90, 180, 270): Sets the rotation of the structure to 0° (no rotation), 90° clockwise, 180° clockwise, and 270° clockwise (or 90° counter-clockwise).

Mirror (¦, <>, ^v): Sets the mirroring of the structure to none (¦), left to right (<>), or front to back (^v).

Load: Press this button once to prepare the outline preview of the structure. When satisfied with the position, press again to generate the structure.; This process may also be automated with the use of redstone.

Corner[edit]

Corner Mode GUI

Corner mode‌^{[Java Edition only]} allows for an easier and automatic size calculation while saving or loading structures.

To use, place on the opposite corner of a save structure block or a second corner structure block. Then, using a save block, press "detect".

When successful, a white outline appears.

Structure Name: The name of the structure on which to calculate the size and position.; Name is case sensitive; it must match exactly with the name provided by the complementary save or corner structure block.

Data[edit]

Data Mode GUI

Data mode‌^{[Java Edition only]} can only be used during natural generation. They mark the location to run a function specified by its metadata input, which can be used only for relevant structures. The structure block is removed afterwards. This mode is the default mode when a structure block is first placed.

Custom Data Tag Name

The name of the function to run.

Igloo: "chest" - sets the loot table for a chest beneath the structure block to "chests/igloo_chest" and sets the loot table seed dependent on the world seed.
End city: "Chest" - Sets the loot table for a chest beneath the structure block to "chests/end_city_treasure" and sets the loot table seed dependent on the world seed.; "Sentry" - Creates a shulker at the location of the structure block.; "Elytra" - Creates an item frame entity with an elytra item inside it at the location of the structure block.
Woodland mansion: "ChestSouth" - Sets the loot table for a chest that replaces the structure block to "chests/woodland_mansion" and sets the loot table seed dependent on the world seed.; "ChestNorth" - Sets the loot table for a chest that replaces the structure block to "chests/woodland_mansion" and sets the loot table seed dependent on the world seed.; "ChestEast" - Sets the loot table for a chest that replaces the structure block to "chests/woodland_mansion" and sets the loot table seed dependent on the world seed.; "ChestWest" - Sets the loot table for a chest that replaces the structure block to "chests/woodland_mansion" and sets the loot table seed dependent on the world seed.; "Mage" - Creates an evoker at the location of the structure block.; "Warrior" - Creates a vindicator at the location of the structure block.

3D Export[edit]

Export Mode GUI

3D Export mode‌^{[Bedrock Edition only]} is similar to save mode, but the structure is saved as a 3D render rather than as an actual structure.^[2] Therefore, structures saved this way can be viewed, but cannot be generated via load mode.

Structure Name: Enter the name of the structure. Case sensitive. You must enter a file name in order to export.

Relative Position: Enter the X, Y, and Z values for the structure here, based on the position of the structure block. Sets the origin of the structure outline.; Maximum allowed distance from the structure block is 32 blocks in any direction.

Structure Size: Enter the X, Y, and Z values to set the distance from the Relative Position coordinates. This sets the opposite corner of the structure, and defines its size.; Maximum structure size is 32×32×32.

Detect structure size and position: Automatically calculates the size and position of the structure using a corner block placed on the opposite corner of the structure.; The name of the structure in the save block must match the name within the corner block, or the size calculation fails.

Include entities: While saving the structure, saves any entities within the structure as well.

Include players: While saving the structure, saves any players within the structure as well.

Structure void[edit]

The difference between air (left) and structure void (right) when "show invisible blocks" is enabled.

Structure void can be placed as part of a structure and are ignored when the structure file is saved.

This results in the blocks at the location where the structure is placed being maintained and not being overriden. For example, if a player saves a 2 block high structure with air at the top and a structure void at the bottom, and loads it into a 2 block high area of stone, the top block becomes air but the bottom stays stone.

Structure void blocks have no collision box but have a small hitbox. Additionally, they are invisible, but are displayed as red cubes when "Show invisible blocks" is turned on in Save mode. As there is no collision box, entities can pass through, although liquids cannot. Similar to barriers, they are visible only when the player equips the item in their hand (or offhand).

Blocks can replace structure voids as they would do with snow layers or grass.
