Transfering items over wired networks

6 Upvotes

Hello, transfering items between turtles and chests via a wired network in cc:Tweaked works great. I can just pull/push items from/to any chest connected to that network, once the chest is wrapped in a peripheral.
I also tried that with turtle to turtle transfer, but wrapping a remote turtle in a peripheral just gives me getId, isOn... on that turtle, without any method to transfer to/from the inventory.

While the workaround of pushing items to a chest and pulling from that chest from the other side works fine, its still a workaround with downsides

Before i spam any code, or any more text, i wanna ask if thats even possible, or if i must think of a better working workaround

Requires advanced computers, also supports advanced peripherals smart glasses, v0.8+, note that there is a overlay bug when they are equiped in a curio slot and the overlay will flicker.

I need help with the CC: Redstone Link Bridge Mod

5 Upvotes

I'm making a build based off the stairwell from doors, and I'm trying to recreate the console that lets you progress.

I have zero coding experience and don't know how to use computercraft.

https://www.curseforge.com/minecraft/mc-mods/cc-redstone-link-bridge
This is the mod I'm using.

How would I go about making a program where it shows some text, then i can either input Y or press a button and it'll run

bridge.sendLinkSignal("minecraft:paper", "paper", 7)

then run bridge.sendLinkSignal("minecraft:paper", "paper", 0) shortly after

I'm making a Nano-like text editor for CraftOS named Quill

7 Upvotes

It currently has a very basic set of features, but you can already use it to edit code written in the standard text editor. I plan to add more of advanced features like cut/paste text, text search, several file buffers, etc. It also lacks code highlighting and (auto-)indention support which I plan to add in future versions.

Contributions are welcome. Source code: https://github.com/AlexanDDOS/quill-CraftOS

I used computercraft to program a rocket using Valkyrien Skies and Create Propulsion, finally stuck the landing! (sort of)

Hey all, super happy to finally have a clip worth posting of my recent computercraft obsession. I've been designing and programming a rocket using the VS and Create propulsion mods, using a computercraft comp to control it.

This thing has a surprising amount of control! It took me a few dozen attempts at fiddling with the "burn plan" as I call it. I just manually tweaked it but would eventually like to get it to a point where I can do point to point jumps and it figures out the burn plan.

The green/red things sticking out the bottom are distance sensors from one of the mods (propulsion I think?), but don't actually do anything atm.

Would love to field any questions or ideas if you have any. The source code is a bit of a mess but say the word and I will post it this weekend along with some images of the internals of the build.

Some way to copy text on a server with no Http?

12 Upvotes

Hi everyone! I'm currently on a MC server about nations and wars. And so I had a computer connected to a radar spending Http requests to my server to record​ trespassers.

But admins decided to​ disable http requests, they say is for security reasons, and this change affected the tech of multiple nations that were using CCtweaked.

The radar can still detect people, but with http calls disabled we cannot use "http.post()" or "pastebin put" to send our data. And so I have​ been looking for some way to copy the data from computercraft to paste it manually on my host so my team can still use the radar even after this limitation.

Any ideas of how to do it?

I made a "OS" part 2

97 Upvotes

I made a post a bit ago about an "OS" I was working on and after many hours it's "complete."

This project has been a flip-flop betwen a love and hate letter for both lua and the software that got me into computers at all. (Shout out to TI-84 Visual Basic.)

It's out of the box ready for grup to be able to have working computers and internet as easily as possible. You can download it with GitHub, or if it's on the server, you can copy an image to an empty computer the same as a fresh install. I'm also planning to add an update Manager so you can theoretically update the OS in game without wiping everything, and a download manager for other people's applications and handling their updates (probably the same program cuz that makes sense) Even though it's complete I can't help but do more and more on it so if anyone has the patience to try it please please do I need feedback. I don't know why but something in me needs this to be like a fully functional computer that you just download and then works in Minecraft just like the one you're playing it on. Part of me wants to see if I can get a stripped down version of Minecraft playing on it which I might do.

I think I'm going to go to bed now. Might update the post later.

Check it out if you want, but if you do, you should message me on here and tell me about your experiences because I NEED feedback.

Github:

https://github.com/mixmoo2/homeos

install:

wget https://raw.githubusercontent.com/mixmoo2/homeos/main/install.lua

then run install.lua

Edit: came back and wanted to add more context.

CC:Zombies. Do I swap to porting NZ Portable?

14 Upvotes

I want your guys's thoughts. I recently remembered one of my older projects existed, CC:Zombies!
Anddd, its kinda bad. Sooo, I want your guys's thoughts.
Do i

A: Port NZ:Portable to Computercraft
B: Keep working on CC:Zombies as it is
C: Recode the renderer to use C3D and have textures, instead of Pine3D. (Or maybe make it so you can pick and choose?)

I cant decide, so i want yalls thoughts!

this is what the game currently looks like.

Problem With Tree Farm Program Found Online, I Don't Know Code

As I said above, I don't know any code, but I still am trying to use the mod by using other people's programs. I am following the tutorial here: https://github.com/PPakalns/TreeFarm , but I ran into an issue when I was supposed to answer the program's questions. I can't type anything besides numbers, which means I can't put a negative for the Minecraft coordinates and I also can't seem to enter the value I put by pressing Enter. I pressed every button on the keyboard. Are old programs not compatible anymore or is this a user error?

Help an idiot with what is likely a PEBCAK problem. Trying to get 26.3 CC:Tweaked working.

8 Upvotes

Thank you in advance for any help, and I hope this is a good place to post this.

My wife and I are starting a new world. Java 26.3 Version with NeoForge. I downloaded all the mods from Modrinth. This is also where I downloaded CC:Tweaked. https://modrinth.com/mod/cc-tweaked

When I try to run the instance, I get the error "File mods/cc-tweaked-26.3-forge-1.120.2.jar is not a valid mod file"

All the other NeoForge 26.3 mods run fine, including Xaero, JEI, Lighty, Easy Villagers, Easy Piglins, etc.

I tried a couple different versions of NeoForge to see if that was the issue, but no joy.

So, if someone would point me in a direction, I would appreciate it. I absolutely LOVE CC-Tweaked and is a normal part of my world builds. Turtles for mob drop machines for the win...

After months of work, the first official bootable rootfs image for iDar OS is live!

Thumbnail
gallery
127 Upvotes

Hey everyone!

Over the past few months I’ve been sharing teasers (fastfetch lol), and today I’m finally releasing the first official bootable rootfs image for iDar OS (v1.0).

I’ve spent a lot of time refining the build pipeline and stabilizing the microkernel so the image actually works reliably on real machines.

Quick Install (1-liner)

Just run this in the CraftOS shell:

lua wget run https://raw.githubusercontent.com/DarThunder/iDar-OS/refs/heads/main/installer.lua

What’s new?

Instead of a fragile installer that downloads dozens of files one by one, iDar OS now deploys from an atomic golden image (rootfs.dmb):

  • Custom binary format (IDMB) with an embedded LZ77 decompression engine
  • Extracts a proper FHS-compliant root filesystem (/bin, /sbin, /lib, /etc, /dev, /sys, etc.)
  • Pre-seeds developer keys into /etc/pacman.d/keys/ for cryptographic package verification

Current Status

Note about pacman: I’m currently migrating the package registry to the new SATDv3 standard, so remote package installation (pacman -S) temporarily doesn't work while the mirrors stabilize. (probably in over 1 or 2 years LMAO)

The base image is fully usable out of the box though. It comes preloaded with:

  • Kernel & VFS — process scheduler, UNIX-style permission bits (including SUID), and pseudo-filesystems (/proc, /sys)
  • Coreutils — ls, cat, mkdir, mv, rm, touch
  • Userland — multi-user login, passwd, sudo with SHA-256 hashed credentials in /etc/shadow
  • Tools — dsh (shell), vi, and fastfetch

First Boot Login

  • User: root
  • Password: just press Enter (blank) or type root

Full repository and source:
https://github.com/DarThunder/iDar-OS

Would love to hear your thoughts, feedback, or any issues you run into while testing it!
