A structure block is used to manually generate structures. They can also be used to save and load structures, alongside structure void blocks.

Obtaining[edit]

Structure blocks are available only using the /setblock, /fill, or /give commands, meanwhile it can be obtained in the creative inventory in Education Edition. Structure blocks when placed are unbreakable in survival and have the same blast resistance as bedrock. This is similar to the command block. In Bedrock Edition, all structure block types are obtainable through commands with data values, including corner‌^{[Java Edition only]} and data‌^{[Java Edition only]} modes and the inventory model, although those three will default to save mode when placed.

UI[edit]

In Bedrock Edition, the UI includes a visual of the structure within the structure border, which makes up for the lack of the corner mode. In Java Edition, however, because there is no visual, a corner block can be used to assist in getting a structure properly within the structure border.

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").‌^{[Java Edition only]}

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.

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^{[JE only]} 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 in Java Edition is 48 blocks in any direction and 64 on horizontal direction and 256 on vertical direction in Bedrock Edition.

Show invisible blocks ‌^{[JE only]}: 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 48x48x48 In Java Edition and 64x256x64 In Bedrock Edition.; When successful, generates a white outline surrounding the structure.‌^{[JE only]} In Bedrock Edition, the outline is green, blue, or red (depending on the axis) and the preview design can be used to see every layer of fragmented structure and to change the structure size to be saved.

Detect structure size and position ‌^{[JE only]}: 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.; Two corner blocks can also be used. It will use the second corner block instead of the structure block.

Remove blocks ‌^{[BE only]}: 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.; Structures can be saved to a file on disk only by manually pressing this button. If a structure block in Save mode is instead powered by redstone, the structure is saved only in memory by default. This is the case even if a file for that structure already exists on disk. Reloading the world clears any structures stored in memory. In Bedrock Edition, the player can set up the structure block so that it saves to the disk even when automated with redstone.; By default, structure blocks are saved in the minecraft namespace. This can be changed by prefixing the structure name with <namespace>: in the structure block.; In Java Edition, structures are saved in .minecraft/saves/(WorldName)/generated/(namespace)/structures. ^{[note 1]}

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

In Bedrock Edition, structures are saved together with other world data rather than a standalone file.

Export ‌^{[BE only]}: Used to export a structure into a .mcstructure file, which can be used to load from the structures folder of a behavior pack. If the structure contains a custom block from a behavior pack, then the block is also saved on the structure block.

Load[edit]

Load Mode GUI for Java Edition

Load Mode GUI for Bedrock Edition

Load mode allows the player to load and rotate saved structure files.

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

Structure files may be found in two locations - in /data/minecraft/structures/ in minecraft.jar for default structures, and in .minecraft/saves/<World Name>/generated/minecraft/structures/ for user-created structures.

The following folders exist in minecraft.jar:

bastion
end_city
fossil
igloo
nether_fossils
pillager_outpost
ruined_portal
shipwreck
underwater_ruin
village
woodland_mansion
coral_crust‌^{[BE only]}^{[more information needed]}

To load a structure from a folder, simply type minecraft:<folder_name>/<structure_name> or if stored at the top level of the structures folder (such as those created in the Save mode) type minecraft:<structure_name>.

Example 1: minecraft:shipwreck/with_mast
Example 2: minecraft:village/snowy/houses/snowy_tannery_1
Example 3: minecraft:my_redstone_contraption

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. Coordinates may be defined as numbers between -48 and 48 In Java Edition, or between -64 and 64 In Bedrock Edition.

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). At 0° rotation < > mirrors across the X-axis and ^ v mirrors across the Z-axis.

Load: Type in the name of the structure and 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 be used only 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 afterward. 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.
Ocean Ruin: "chest" - Creates a chest at the location of the structure block, setting its loot table to either "chests/underwater_ruin_big" or "chests/underwater_ruin_small", with seed dependent on the world seed.; "drowned" - Creates a drowned 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.^[1] 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. The player 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 64 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 64×256×64.

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.

Ender Dragon[edit]

Structure block cannot be destroyed by the ender dragon.
