Talk:Structure Block

Speculating that the structure block's blast resistance is the same as bedrock or obsidian
The structure block's blast resistance is probably the same thing as bedrock or obsidian. It's just a speculation, I'm not really sure that it is but it might be. RosalinaFan573 (talk) 18:41, 31 July 2015 (UTC)
 * Blew up one with some TNT. It's still there. Dittoslash (talk) 13:06, 12 August 2015 (UTC)
 * New (more reliable) test: ~300 TNT minecarts (in this) failed to blow up the new(?) Structure Block, obsidian, and bedrock. Dittoslash (talk) 06:25, 21 May 2016 (UTC)
 * Multiple explosions aren't cumulative; if one TNT isn't able to break a block, it can't be broken with any amount of TNT. -- Orthotopetalk 06:38, 21 May 2016 (UTC)
 * Use the command /summon Fireball ~ ~ ~ {ExplosionPower:100}} (or more than 100) to create a fire ball with a high explosion power and punch it into the direction of the structure block. Only that can destroy it. I didn't look at any wiki page (online with phone) to create the command, could please someone check if it's correct? Fabian42 (talk) 07:54, 21 May 2016 (UTC)
 * There's no point to continuing to speculate when people have looked at the code and determined the exact value. Anomie x (talk) 14:43, 21 May 2016 (UTC)

Where do structures save?
I have created (and saved) several structures, but I can't seem to find the file. I heard once that they would save in the "structures" folder in the world files, but I can't seem to find this folder. I have even searched the entire minecraft directory for one of my structures (using the search function), but still no luck. -- Luke18033 (talk) 00:31, 19 May 2016 (UTC)


 * Saving doesn't work on windows. See mcbug:102052. –Majr ᐸ Talk Contribs 07:31, 20 May 2016 (UTC)


 * Then why am I still able to load the structures in the same world, even after I quit and re-enter? The structures are saving somewhere, probably in the world folder, I just can't find it. -- Luke18033 (talk) 20:35, 20 May 2016 (UTC)


 * It's saved in memory until you close the game entirely; it will remain in memory if you only exit the world. Skylinerw (talk) 19:22, 20 May 2016 (UTC)


 * I'm pretty sure I've exited the game too, but idk. I'll have to test it later. -- Luke18033 (talk) 20:34, 20 May 2016 (UTC)


 * Just found that the structures aren't saved on relaunch. What was happening before is I was saving the structure again every time I opened the world. -- Luke18033 (talk) 22:55, 20 May 2016 (UTC)

"Blank" structure block?
The gallery, fourth from last image, says it shows a 'blank' structure block from 1.9 and then 1.10. Are these unused textures or something, or are they used in some circumstances? – Sealbudsman talk/contr 21:12, 21 May 2016 (UTC)


 * These are just the textures of structure blocks that are still in the Player's inventory but haven't been placed and assigned a mode yet. There currently isn't a way to place these "blank" structure blocks without using a custom resource pack, since it doesn't have a known data value. Superspace (talk) 07:19, 23 May 2016 (UTC)

Huge Discovery for Map Makers
So I just figured something out in the game, and I don't know if anyone else knows as well, but as far as I know I am the first to find out. The structure block can be activated by redstone. This means it can be used to create automated structures in custom maps. –Preceding unsigned comment was added by 121.217.2.180 (talk) at 3:07, 08 July 2016 (UTC). Please sign your posts with

Structure Blocks Save feature
In a lot of youtube videos I've seen, it's stated that only the Load option of structure blocks work with redstone. I have discovered that you can also Save structures with redstone, but only if the structure file already exists. There doesn't seem to be a good section to add this, so I'm just dropping this here. This is as of 1.10.2 72.224.250.183 10:10, 10 August 2016 (UTC)


 * Slight correction: saving via redstone signal only saves the structure to memory. It doesn't matter whether or not a file existed prior. Structures are only saved to file when using the interface. Skylinerw (talk) 10:32, 10 August 2016 (UTC)

Self-loading/Recursive Structures
Using redstone it is possible, with slight difficulty, to create self loading and even recursive structures. In other words, you can have a Load structure 'A' inside of structure 'A' and auto-load it via auto activated redstone. The cavit is that structures are loaded when their powered state switches from off to on. In other words, if you save it with redstone powering the load block, it will not auto-load itself.

The easiest solution is to use a observer block. the observer block always sends a pulse when it's initially loaded. Note however, that the observer block will not send another pulse after that even if you push load again, It must be replaced or updated.

Using this approach you can load several different structures from within your structure. This is useful when your structure has alot of a custom structure in it, such as a statue or red stone timings. And especially useful for oversized structures(larger than 32x32x32) since it allows you to load all the associated structures in one click.

Potential Pitfalls and Workarounds

Attempting to load many structures simultaneously may freeze low end PCs. Instead of calling a large group of load blocks at once from within one load block, try creating a load block chain or tree.

Most redstone triggers must be destroyed in order to reload contained structures. The best solution is to have the structure replace its trigger, command blocks erase the trigger, or use self replacing command blocks as the trigger. I prefer using a self replacing command block. Create by placing a command block down away from your structure and set it to chain, unconditional, always active (chain stops it from running now). Then type 'setblock ~ ~0 ~ minecraft:redstone_block'. cntrl + middle click it and place it next to all your load blocks, preferably (though not required) inside the region it will load into. Set the newly placed command blocks to impulse.

Embedded Load Block's structures will not be rotated/mirrored with the containing load block.

Self Recursive Structure

Be extra careful when creating recursive structures, it is very easy to make a runaway recursive structure loader which will recursively load the structure over 1,000 blocks per second (depending on computer speed/structure size). And once done its very hard to stop it. I recommend using command block triggers with a testfor condition, such as 'testfor @p[r=10]'. You can then follow the generated structure to generate more, You could also use the scoreboard and control the generation that way. (eg. testfor @p[r=30,gen_struct_min=1])

This works reasonably well when the load area and save area do not overlap. When they do overlap, I have had instances where the structure doesn't fully load. This can be used for recursive structures, useful for building staircases and towers spanning from the top to the bottom of the world. Multiple repeaters can be used to slow down generation, and you can break the load block before it is called to stop it. The torch can be replaced with a pressure plate or tripwire to make an trigger based expanding structure, for instance generating a bridge by flying through the tripwire. Similar method can be used for a piston-less/soundless moving path. With additional effort, the structure blocks and redstone can be auto-removed. For instance by loading the structure over it, or by deleting it with command blocks

This can probably be used in conjunction with command blocks and/or hoppers to create chunk loaders, load chunks dynamically, or (although its a really bad idea) even load chunks unconditionally with little effort.

Loading structures from minecraft.jar
When this block is in load mode, how do I load structures from that folder, more specifically, rooms that are found in Woodland mansions? What am I supposed to type? VeenM64 (talk) 21:01, 9 March 2017 (UTC)


 * Structure blocks will only grab files that exist in that specific world's "structures" folder. You have to copy it from the jar into your world folder, naming it whatever you want. Skylinerw (talk) 01:39, 10 March 2017 (UTC)


 * I don't get what you're saying. And you haven't told me what to type into the structure block's input. VeenM64 (talk) 20:19, 16 March 2017 (UTC)


 * Default structures are found in the version jar . However, for some reason I was under the impression that they cannot be accessed without extracting (likely because I tried to use a namespace, which isn't the proper format for structure blocks). You would start from the "structures" folder and type the filepath as it appears in the jar. For example, to load the top of an igloo, you would insert "igloo/igloo_top" into the structure block to load it. Skylinerw (talk) 20:54, 16 March 2017 (UTC)

Trivia section?
After reading this page, testing things and verifying my idea with the Trivia section of the Style guide I can't help wonder if we shouldn't add one? I think these items could definitely be interesting to add but they don't really fit in the current page:
 * Players can't use 'pick block' on a structure block to pick it up with its set definitions.
 * After loading a structure the structure block can be switched to save mode which will automatically fill in the correct structure size. This allows players to load, edit and then update a saved structure.
 * Structure load and save blocks can be triggered by redstone:
 * When a structure load block gets triggered it will try to load the specified structure.
 * When a structure save block gets triggered it will save any defined region to memory.
 * Note that structures saved to memory have a higher priority than structures of the same name which were saved to disk.
 * In order to remove a structure from active memory a player needs to quit and reload their current game.

Food for thought? - ShelLuser (talk) 17:15, 22 August 2017 (UTC)
 * They don't seem trivial to me, that's stuff that should normally be in the usage section, although this usage section is a bit crowded already. I'm adamant about having it included in the article, so if it doesn't fit anywhere else I'll make do with a trivia section.
 * Putting the saving to memory-vs-disk as a sub-subpoint to something about redstone doesn't seem right. Give it its own bullet. 86.82.30.109 17:48, 22 August 2017 (UTC)


 * All these points are either incorrect (you can "pick block" on a structure block and preserve its settings), already mentioned (redstone activation) or something that should just be added to the main page. So I removed the Trivia section 86.82.30.109 added. --Pepijn (talk) 20:57, 23 August 2017 (UTC)

Structure block in Windows 10 Edition
What software can I use to open the  file after exporting? —— Lxazl5770 zh.patroller （ 论 • 功 00:11, 28 October 2017 (UTC)

3D export mode
This article states, in subsection 2.5 ("3D export"), that 3D export mode has the following option;
 * "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 size calculation will fail."

But it also says that corner mode is only available on java edition, "Corner mode [C]". I deleted the above subsection "Detect structure size and position", but it was reverted. Can someone explain to me why my edit got reverted? Robbob (talk) 17:44, 27 August 2018 (UTC)


 * Looks like reverted the edit in Special:Diff/1247677. I just pinged him to the discussion. It is considered good practice to leave an edit summary when making major changes to pages or removing sections - otherwise the edit may be mistaken as vandalism when it's really not, such as this case..-- Madminecrafter12 Orange Glazed Terracotta.png to meLight Blue Glazed Terracotta.png 17:49, 27 August 2018 (UTC)

Configuring structure block to save using redstone
AFAIK there is not way in the Java version of the game to allow users to save a structure to disk using redstone. Even if you first save the structure manually, and then trigger the structure block, it will not write to disk. There is no option in settings, no tag in the level.dat and no gamerule (as far as I can tell) that changes this.

I recently edited the page to reflect this. No explanation had been previously provided as to how you could save to disk using redstone, so I assumed it was a mistake.

Only a few hours ago someone changed the page to say that, yes, you can in fact save to disk using redstone. Again, with absolutely no explanation. Could someone who actually knows how please add a sentence or two to the 'Save' section on the Wiki? –Preceding unsigned comment was added by Otoomey (talk • contribs) at 21:27, 27 April 2020 (UTC) (UTC).
