Litematica Printer

Note

The 1.21 version of litematica-printer only works on 2b if the client connects using any 1.20 version (1.20.4, 1.20.6 etc). The 1.21 printer currently flags a specific 1.21 movement check in GrimAC preventing your from moving while placing blocks.

This extension adds printing functionality for Litematica fabric 1.21, 1.20.4, 1.20.0 ,1.19, 1.18 and 1.17 versions. Printer allows players to build big structures more quickly by automatically placing the correct blocks around you.

Warning Minecraft Version 1.21

Since there is no official release of Litematica for 1.21, the printer uses a update fork of it and MaliLib.
This fork is not official and may contain bugs or issues. If you encounter any issues with the printer, please report them to the fork's repository.
This fork is not guaranteed secure as it isn't an official release.
1.21 Litematica repository: Litematica
1.21 MaliLib repository: MaliLib
USE AT YOUR OWN RISK

Download

Check the GitHub release page for the latest version of the printer for your Minecraft version: Releases

Installation

1. Download and install Fabric if you haven't already.
2. Download the latest Litematica Printer release for your Minecraft version from the releases page (The files can be found under "assets").
3. Download Litematica + MaLiLib and Fabric API (≠ Fabric).
4. Place the downloaded .jar files in your mods/ folder.

If this is the first fabric mod you are installing, here's an informative video on how to install Fabric mods.

How To Use

Using the printer is straightforward: You can toggle the feature by pressing CAPS_LOCK by default. To configure variables such as printing speed and range, open Litematica's settings by pressing M + C and navigate to "Generic" tab. Printer's configuration can be found at the bottom of the page. You can also rebind the printing toggle under "Hotkeys" tab. Holding down V by default will also print regardless if the printer is toggled on or off.

2b2t Grim bypass

This printer is Grim compatible if the printerRotatePlayer option is enabled in the printer settings. This option is enabled by default.

I recommend to use the FreeLook option when printer as you will be able to look around while the player rotates to place blocks. To do this go to Litematica Settings > Generic > printerFreeLookToggle and set it to a keybind. Before printing press it to activate FreeLook. There is also printerFreeLookThirdPerson which will auto switch to third person view when FreeLook is active. Both togglePrintingMode and printerFreeLookToggle can be set to the same keybind to activate them at the same time. The FreeLook is programmed to attempt to move you in the direction you are looking at even if the player is rotated.

Issues

If you have issues with the printer, do not bother the original creator of Litematica (maruohon) or the original creator of litematica-printer (aleksilassila) with them. Contact me instead. Feature requests or bugs for this Fork can be reported via GitHub issues, or via Discord (@IceTank).

Before creating an issue, make sure you are using the latest version of the mod. To make fixing bugs easier, include the following information in your issue:

• Minecraft version
• Litematica version
• Printer version
• Detailed description of how to reproduce the issue
• If you can, any additional information, such as error logs, screenshots or the incorrectly printed schematics.

List of know issues

Currently, the following features are still broken or missing:

• Placing liquids (printing in liquids works though)
• Current algorithm for placing rails isn't perfect, sometimes it can't place all the rails (to avoid placing anything incorrectly).

Also, I have decided that features that fix existing builds, such as automatic excavation or correcting incorrectly placed blocks are out of the scope of this mod.

Building and Contributing

Each Minecraft version has its own submodule, that has the default fabric mod development tasks and contains the version-specific code. To reduce the amount of work I have to do to make it work for multiple Minecraft versions, I created this hacky gradle script that copies the common code over to the other version implementations. Currently, the script copies everything, except implementation/ folder, which should therefore be the only places containing any version specific code.

If you want to make changes to the mod, I would recommend you to first implement them for the latest Minecraft version (1.19), and then running the syncImplementations gradle task, found in the same subproject as your changes, to copy the common code of that submodule to the other implementations. After that you will only have to write / copy manually the version-specific code (found in the implementation folder) to the other versions and do some testing to ensure everything works.

Contributions are welcome and appreciated! I have recently rewritten the whole project, so that it would be much easier to work with.

Also, if you know a better way to develop for multiple Minecraft versions that doesn't involve multiple git branches or hacky gradle scripts (perhaps a way to share common code between the implementations?), please let me know.

Useful gradle tasks:

• [v1_19/v1_18/v1_17]:syncImplementations
  • Copy over common code to other implementations
• buildAll
  • Build all implementations and copy their jars to build/ directory for easy distribution.
• [v1_19/v1_18/v1_17]:runClient
  • Start the target Minecraft version
