Simple Schematics

Schematic Printer

Craft the printer with four iron ingots at the corners, four redstone dust at the edge centres and a crafting table in the centre. Place it yourself, choose a schematic and bind it. It builds from nearby containers under its owner's control, with Start, Pause, Resume and Stop buttons and redstone triggering. Choose one print, repeat at one target, or advance by X/Y/Z spacing. Batch 0 is unlimited; 1 to 9,999 sets a finite limit. A comparator reports ready, active, paused/blocked and complete states.

Preview schematics in the world, paste them in Creative, or build them in Survival from your chests.

Fabric needs Fabric API, and that's it. Modded blocks work too.

Simple Schematics is a mod for loading schematics into your world. A schematic is a saved copy of a build, such as a house, a farm or a castle, that can be placed in any world.

Pick a schematic and it appears as a see-through preview, showing exactly where every block will go. Move it, turn it and flip it until it sits where it should. Then:

• In Creative, paste the whole build at once. If it's wrong, undo it.
• In Survival, the mod builds it for you, block by block, using materials from nearby chests and your inventory. A Materials list shows what the build needs and what is still missing.

It reads the common schematic formats, including Litematica and WorldEdit files, and works with blocks from other mods.

Put your .litematic, .schem, .schematic or structure .nbt files in the schematics folder, hit V and pick one. It shows up in the world as see-through blocks, using the real models, so signs, banners, heads, item frames, water and so on all look like they should.

You move it around in the world rather than typing in coordinates. G cycles between position, move, height, rotate and mirror, and Ctrl + scroll (or the arrow keys) nudges it one step at a time. You can view it layer by layer and turn the opacity up or down.

Million-block schematics have been tested; import and server work still have resource limits. It also remembers where you put each schematic in each world, so you don't have to line it up again.

In Creative it's one button. You choose whether to include air, entities, mobs and container contents.

Undo works on your last ten pastes. You can undo the whole thing, or only the blocks nobody has touched since you pasted.

Big pastes go in chunks with a progress bar, so the server doesn't freeze up.

The Materials screen shows what the build needs, what you've got, and what you're short on. There's a "missing only" filter, and a button to copy the missing list.

It pulls from containers within 10 blocks of the build, your inventory, or both. You can lock inventory slots and leave out any chest you don't want touched. Blocks that are already in the right place cost nothing, and if you don't have something you can swap in a substitute.

Then you watch it go up, anywhere from 1 to 200 groups a second, with sounds and particles if you want them. You can pause or cancel whenever you like. Cancelling gives back anything that wasn't used.

It builds item frames, paintings, armor stands, boats and minecarts too, items included. Living mobs end up on a "Manual work" list for you to sort out yourself.

Builds carry on across restarts. When you come back, it waits for you to hit Resume and checks its progress before carrying on, so nothing gets placed or paid for twice.

Some modded machines store data in ways the mod can't make sense of by itself. Rather than guess and break something, it marks the block as needing a rule, and an operator can write one in game.

Open Rules from Settings or the Library, or press Add rule next to the problem on the Materials screen to start from a rule filled in from your schematic. You mark which saved fields are settings (always copied) and which are contents like items, energy or fuel (only copied if you ask). You can also set exact material costs and decide what happens to links like pet owners.

Rules take effect right away. Server owners and modpacks can also ship them in a datapack.

It needs to be installed on the client and the server. Singleplayer just works.

Everyone's pastes, undo history and builds are their own, so nobody else can undo or control them. It goes through the normal break and place permission checks, so protection mods that use those still work.

Schematics from older Minecraft versions get converted. If there's something it can't read safely, it tells you what and where instead of quietly getting it wrong.

Blocks from any mod you have installed can be previewed, pasted and built. There's no allowlist. If a block's mod isn't installed, you can swap it for something else or leave it for manual work.

Tested on NeoForge 1.21.1:

• Create and Copycats+: machine settings and material costs carry over.
• LittleTiles: plain tile groups keep their shape.

It reads schematics from Litematica, Forgematica and WorldEdit, but you don't need any of them installed.

Grab the file for your Minecraft version and loader, and put it on both the client and the server.

You can rebind all of these in Minecraft's Controls menu.

More screenshots are in the Gallery tab.

Is Litematica or WorldEdit needed? No, it reads their files itself.

Where do schematic files go? In the schematics folder in your game folder, next to mods and saves. There's an Open folder button in the browser if you can't find it.

Can it go in a modpack? Yes. It's licensed LGPL-3.0.

Does it need to be on the server? Yes. The server does the actual pasting and building, which is what stops anyone from duplicating items with it.

A block says it "needs a rule". What now? That block stores data the mod can't copy safely yet. You can place it with default settings, leave it for manual work, or get an operator to add a rule (see Rules above).
