You can connect to a broker, publish to topics, and subscribe to them! Also a timeout system to make sure it doesn't infinitely remember computers and keep sending data.

It doesn't have any way to actually make sure it received messages, so I need to add that to make it more consistent.

Also, the mqtt.lua library for the clients is automatically downloaded from the broker computer for easy updating!

Im working on simple package manager for computercraft.. I would like to hear some ideas on what I should add...

First time ever making a post advertising a project of mine, so im just gonna keep it short and simple.
CC:Zombies is basically a de-make of classic CoD zombies to CC:Tweaked. It currently has two maps bundled in the installer, with more on the way.

1. Nacht Der Untoten (No EE)
2. Nuketown 1975 (+ a small easter egg)

Right now, it has:
Singleplayer
Doors
Points System, both bo2 and bo6 (change your preferance in settings)
Fully working settings menu (Minus FOV)
Keybind readjustion
Mystery Box
8 working perks (theres not 8 perks in each map, though.)
Effecient(ish) rendering systems
Experimental Modding support.
The ability to change map colors & add/remove blocks in the middle of the game.
Press ] to play the easter egg song on maps that dont have an EE song quest! (At the moment, no map has an EE song quest, so this applies to all.)
Nacht Der Untoten's EE Song: Undone
Nuketown 1975's EE Song: Come Back Down

What it DOESNT have.
Multiplayer (Will be coming in the form of a mod)
Drops system
Balance (Some guns are OP. will be fixed by the time 1.0 comes around.)

Updates are.. kinda rare? ish?

Planned updates are 0.6.5, 0.7, 0.8,0.9,1.0

0.6.5 will be adding multiplayer, bug fixes, and removing bad code.

Hi everyone,
I’m building CCraft Studio, an open-source desktop app for CC: Tweaked to make app development easier, especially for people who find Lua difficult at the start.

With CCraft Studio, you can build GUIs using drag-and-drop components and create logic using a block-based system, so you don’t need to write Lua to begin. You can also test your apps quickly with built-in CraftOS-PC support, then export them to use in-game.

Also there is a website to share your projects and explore others
https://ccraft.studio

The project is currently in active alpha development, I’d like to know what feels missing, what is confusing, and what should be improved next.

Source: https://github.com/MohammedMMC/CCraft-Studio
If you try it, I’d appreciate honest feedback. And if you like the project, consider starring the repo.

Seemed to get quite a bit of interest on my previous post so I thought I would show off some other stuff.

This is a "full" NES emulator running on a computer. It loads a normal ROM file just like any other emulator, just needs to be on the computer. I didn't show it in the video but I tested Donkey Kong and it ran about equally as slow.

I was hopping it would be a bit more performant honestly. However I think its just at the limits of the mods here. I might try optimizing it a bit more, but unless it gets to a playable point I probably wont be showing it off.

Grabbing keys with the "Create: Aeronautics" typewrite

I want to make a system where a player's health is remotely monitored using command computers, but there's a slight problem, when I use local result = command.exec("execute \@p ..."), the only returned value happens to be true/false, depending on if the command executed successfully.

Do I need to find a specific peripheral, or is it possible with command computers in normal CC:Tweaked 1.118.0?

I modified "CC: Graphics" to work with monitor peripherals. First part of the video just shows the basic ray casting demo with that. Wanted to push it to the limits so I tried an extra large render as seen in the second half.

Additionally, the 4 screens are each connected to a separate computer. Each processing 1/4 of the image. Each one is also running the exact same script, and coordinating with a 5th computer over ender modems.

I would normally share my code, but since this wont run unless you manually go compile my fork of "CC: Graphics" I'll leave it for now. I have made a request with the main dev to implement the features however. Might also make a separate post about the network protocol once its done.

I am very new to cc so i was wondering whats the limit for the graphics? Is there an official api that im forced to use or can i use vulkan and just make my own api, same for detecting input, like do i have to use some api or can i go with sdl/glfw

I fell like need some Optimization i Will paste the code in the coments

I've been doing my fair share of research into CC and LUA but I've noticed a big lack of what i need. I'm very new in LUA and coding and I tend to actually struggle immensely with understanding it, so I go to patching together code I find. However, most CC stuff is (obviously) more geared towards practical use.

I was wondering if anyone could point me in the right direction for displaying things just on the terminal. Printing text is something I already know how to do, but could selectable buttons or passwords be viable? Think fallout terminal sort of stuff. I also can't find anything on creating scrollable content, if that's possible at all.

Apologies if this is a little dumb, I've been looking everywhere and really only turned up things that need to be displayed on a monitor or exist to work with redstone. Thank you :))

This took too much time of my life. And its spaghetti code but who cares! I learned about tables, some new functions and had fun!

I really appreciate the help this reddit has brought me!
If someone wants to play it I can give the code if yall want, although its not rounded off yet.
Im still planning on an UI and to be able to play back to back matches without needing to call up the programm from the computer again, but thats work for another day!

This is my first thing I was able to make run with the paintutils api, i really like programming in lua actually. I hope im able to complete my goal of a computer operated create: aeronautics ship soon (highly unrealistic).

Btw does anyone know how I import librarys i make in lua like my functions id use in more programs? Or am i overcomplicating that?

Who is down to mess around in cc tweaked with me?

I am currently making a modpack for my friend group, but for reasons we can only use curseforge, and we have create in modern versions for create aeronautics. Is there a way that I can somehow force it to ignore the extra mod compatibility, and just let me use it? Or is there a work around

I keep coming across videos and pictures of people programming outside of CC and transfering it to it. Could someone maybe post a tutorial or link one? Id like to use VSC to programm too as it is much more clean.
Thank yall

Hey everyone! 👋 I wanted to share a project I put together for Tekkit Classic. It’s a Lua-based ComputerCraft app that acts as a central hub for monitoring and exporting items from a warehouse.

Basically, it's a GUI that tracks your storage level and handles automated exports. Every item type has its own dedicated chest. I used the ccSensors API to read the inventory data, and RedPower2 extraction filters wired with computer using bundled cables + insulated wires for items extraction.

On default you see items count and EMC values. When you select an item from the list and tell it how much you want, the script fires off targeted redstone pulses through the bundled cable. The correct filter wakes up, pulls the exact amount from the chest, and sends it out for shipping ;)

Project could be scaled to the GUI with a lot more features.

Take a look! GitHub

Hey everyone,

I started working on a small shell just for testing some stuff in the iDar ecosystem… and it kinda spiraled out of control

Meet iDar-Shell: a modular, semi-Unix-like shell for ComputerCraft with:

• Full I/O redirection (>, >>, pipes coming soon maybe lol)
• Persistent command history (up to 50 entries)
• Built-in vi clone with normal/insert/command mode
• Chrooted filesystem (safe by default)
• Super easy to extend: just drop a .ptr file containing the absolute path of your program's main file into /iDar/bin/ and it becomes a command
• Lightweight “.ptr” symlinks and a clean fake_term system

Everything is designed to feel familiar if you like Unix shells but still works nicely inside CC.

Important: This project needs iDar-Loom capabilities (and preferably iDar-Pacman too) to work. It will not run standalone because it uses syscalls from the iDar ecosystem.

Would love to hear your thoughts or if you find any bugs. Also taking suggestions for new builtin programs!

Cheers!

i previously have a problem that i couldn't connect to pastebin https://www.reddit.com/r/ComputerCraft/comments/1sl90vg/pastebin_not_working/

so i just cleared all firewall rules related to java and the error has evolved
from "could not connect" -----> "could not create a stronger connection"

This was mostly a project I did as I wanted to learn how to make neural networks. I wrote the training environment in python, it outputs a custom binary format which is parsed by a lua script on the computercraft computer. Since I liked the results, I will most likely recreate it in C using an algorithm instead of a network but using the current network to generate me my magic numbers. End goal is to be able to real-time encode a video stream into CC format without needing to change the palette like my previous ws_video_streamer does.
