How do I even make a lua obfuscator?

I know someone already ask this but im asking like how does it work tbh I dont mind if it was fully made using lua like that prometheus obfuscator or using c or java of whatever type of programing language you know

Any simple ways a 13-year-old could earn money with Lua?

I’ve been learning Lua for about a year, mostly with Luau, and recently I’ve started using the LÖVE framework to make games. I’m 13 (in 8th grade), so I know I’m still pretty young, but I was curious: are there any simple or realistic ways for someone my age to make a bit of money with Lua coding?

Best Lua IDE?

Usually I just use Notepad++, but I have tried using Intellij with the Lua plugin and that was so-so.

Do any of you guys have suggestions?

setmetatable and index

I'm doing more on classes - and I'm making a class


MyClass = {}
function MyClass:new()
o = {}

setmetatable(o, MyClass)
self.index = MyClass


return o
end

function MyClass:myfunc()
print("myfunc called")
end


c = MyClass:new()

I realise the manual example uses 'self' rather than MyClass - but I'm not looking for inheritance yet.

And I'm wondering why I need both to set the metatable and index to MyClass. Just setting the metatable fills the metatable of c with fields named after the MyClass functions (eg myfunc) that point to the metamethods - so they should be callable? Yet calling them is calling nil. Why do I require index to be set as well?
I've read the manual on the index metamethod and I see how setting index to the MyClass table and the index metamethod is called if there is no field in the metatable - yet the metatable of c has the field myfunc in even if I miss setting index.

How to install a package in luajit?

I have tried to install packages in luajit using luarocks but it fails due to luajit’s maximum 65536 constants limitation.

1. Is there a way to install packages in luajit using luarocks?
2. What are other available alternatives?

Save system in Roblox Studio

Hi everyone,

I'm currently developing a multiplayer tycoon-style game in Roblox Studio where players manage animal mutant merger plots where they can build pens, hatch eggs, and merge animals.

Here’s the core design:

\- There are 5 unique plots in the world.

\- Players can scroll through and claim a plot they like.

\- Once claimed, they can build, place items, and interact with the world only within their plot boundaries.

\- There’s a central area with NPC shops where players can buy/sell items using an in-game currency.

What I Need Help With:

I’m trying to build a save system that:

\- Persists player progress across sessions (plot ownership, structures, inventory, currency, etc.)

\- Restores placed items on their plot when they rejoin and claim it

\- Supports respawning without losing plot ownership

\- Enforces build restrictions so players can only build inside their own plots

\- Is scalable, so I can add new features (animals, currency types, items) in the future without rewriting everything

I’m still very new to noscripting, so obviously I have been using GPT but have arrived at a dead end, what's the best way to go about this?

First time defining parameters of a custom function to create hexagon grid in TIC-80

So I want to make a civ-like game (eventually).

Today I decided to try and make just a grid and it was more complicated than I thought it would be.

First, I had to refresh my geometry knowledge. I confused hexagon with octagon, which was silly. But then I assumed diagonal lines are tilted at 45 degrees leading to me making very ugly hexagons. I went searching what angles do regular hexagons have and just to make sure, I double checked 30-60-90 triangle rules lol

So this is the final product and exactly what I was planning to achieve.

In the code I started with defining all points of the first hexagon and putting them into a list. I picked the length of each side equal to 8, starting with the top left diagonal line.
If you cut the upper part of a hexagon off, you'll get a triangle with 30-30-120 angles. You can then divide that triangle into two 30-60-90 triangles and calculate the distance between points as shorter sides of those triangles.

One is twice as short as hypotenuse. (8/2=4 which is the value of y1)

For the other I just used Pythagorean theorem.

Figuring out shift values was the most painful process and ngl a lot of it was guessing and intuition.

To actually draw a hexagon I used "for" loop of "line" function and added parameters to shift coordinates.

Then I created function to execute previous function in a loop while shifting it's x coordinates to create a row.

I added the same function, but with half of the x shift and full y shift. Hexagons aren't squares and can't just be stacked right on top of each other, but in between. Now it creates pair of rows which can be stacked without an x shift.

And finally... I just stack em.

I know it's not the clearest code, but it's 3am and I'm just happy it actually works despite me never setting parameters for a function before.

Sentry SDK for Lua

This week is hackweek at Sentry (crash reporting service) and I wanted to try building an SDK for Lua:


https://github.com/getsentry/sentry-lua


The idea was to get a core set of Lua libraries (written in Teal) that are platform agnostic (aka: can run on standard Lua, LuaJIT, sandboxed in Roblox, etc) and then a set of platform specific libraries that could be used to have the SDK work on those platforms. For example, sending network requests.


It's very early days, but I got some CI that runs tests on Mac and Linux on different versions of Lua and LuaJIT. Some examples, including LÖVE (love2d framework) and Roblox. And I got it working on Xbox a minute ago but it's too duck taped to push so far, but I'll try to push this if not on the public repo, on a sentry-xbox private repo we can send invites to if folks want access.

LPEG and luajit: Lua is Awesome

This post may not be constructive or interesting, but I need to share my enthusiasm.

I started writing a VM entirely in Lua for my Plume language.

The idea was that "the VM will be horribly slow (inevitably, since it's an interpreted language running an interpreted language), but it's a prototype that can be ported to C later."

For parsing, instead of my "clean and serious" code, I thought, “Well, LPEG seems pretty solid, I'll do something quick and dirty just to get the AST out in one pass.”

In short, "quick and dirty" for prototyping. How wrong I was!

LPEG is monstrous. Very demanding in terms of abstraction, but once you understand the principle, it allows you to parse complex grammars with ease.

But parsing isn't everything: you can arbitrarily modify the capture flow in a simple and transparent way.

In the end, my "quick and dirty" code was shorter, more efficient, and easier to read than the old "clean code".

As for performance... Remember, a VM written in Lua isn't going to be lightning fast, right?

Well, thanks to the black magic of luajit, on the few benchmarks I wrote, Plume outperformed Lua 5.1 by 30%. Yes, on a 1-week dirty VM.



Lua is awesome.

From a stupid old man ready to scream in anguish, aka a summer ruined by Microsoft

Apologies in advance for the novel.

Background.

I spent my summer taking a break from Fortnite after Chapter 6 season 3. I ended up trying a game in my Epic Library, Kingdom Come Deliverance - 2018, not KCD 2. It is a great game. The mod bug bit me. It always does.

Long story short, I started modding, using Basic Notepad++ and luanoscript from github
[https://github.com/dail8859/LuaScript](https://github.com/dail8859/LuaScript)

I am rather simple. On unix I grew up on pico and then nano on later BSD versions (dont get me started on how much I hate Vi/Vim. It worked, so I didnt bother with anything. I know a bunch of languages, but not xml or lua, so I learned slow, I learn through failure, needless to say I learned a LOT. By early July I got done what I wanted modding wise - I mod through the Nexus. I had set 4 goals when I started. 3 were done. The last, final and most difficult was making the physics engine actually a physics engine, and ripping out the IK - Inverse Kinetic Animation system, I had quit it 3 different times since late May when I started, honestly I thought it was a fools errand.

But I hate to lose, quit or otherwise fail, so like a fool I kept at it. Eventually I did actually start seeing ragdolls and other forms of actual physics in play. My goal was to have it done by now. Classes started last Monday - I am a Linguistics major, even though I know like 8 languages now.

Now, as they say, it is always darkest before the dawn, and I was almost done. Murphy has laws about that

8.13.25 hit like a fucking freight train. I actually didn't install the update for a couple of days, until 8.17.25

Microsoft update nuked me.

Everything stopped functioning properly I pretty much pulled my hair out in frustration

In what little time I have had this week, I actually worked with an AI, and lemme say I hate AI. I figure if I cant do something myself I shouldn't do it. But, I gotta say that JDroid, that is a cool little fella. Lemme say I am also not one for asking for help, but, pride is a bitch and I know when to get rid of it when applicable. Now, we worked out a semi-tenable solution, and learned what happened, though it took me a couple days to figure that out.

We ended up creating a virtual environment, system, network, etc. And it mostly worked, mostly. except for basicactor.lua which I have turned into my main file and it has grown a LOT since I have had to reverse engineer the entire physics, hit reaction, recoil, combat and death system in order to do all of this. But now, as soon as I touch it, it breaks.

CryEngine uses its own self contained lua environment and mini network for its client and server system. Since it is originally a single player system, made to run as a multiplayer environment. KCD runs on simple local server and the game client actually runs through that. Previously locals were called as such. It was simple, easy, it was easy, i didnt need a doctorate in programming to get that far, did I mention all my learning has been pretty much self taught since the late 80s? yea. I dont claim to be good, but I can work my way around gdb and a compiler really easy. turbo Pascal, c/c++/objc/java/javanoscript

How did I get nuked? Well. The last security update tossed a luaapi.dll into system32.dll

This shattered the self contained Cryengine lua local like a hammer and crystal. It also made luanoscript fairly useless. Luanoscript also utilizes lua 5.3 Now, you probably know where this is going right now.

File:951: attempt to index a nil value (global 'BasicEntity') any type of local dependency is gone, as luaapi.dll turns the entire system upside down. Now, using what is below I can get everything else to function, but if I even touch basicactor.lua it breaks, it is currently broken again and I am pulling my hair out.

In a nutshell, I want my global environment or my self contained lua noscript extension to function. I tried vs code. I am not making heads of tails of it and I do not have all summer

now to learn a new system. I just want this done so I can focus on my classes and move on from this.

Uninstalling the update does not yield any results, on a reboot it will just reinstall it.

I am at my wits end here

\-- Original

\-- CryEngine's Lua Environment
\-- Controlled, embedded Lua interpreter
\-- Direct access to engine functions
\-- All noscripts running in the same context
\-- Direct access to game globals

\-- After Windows Update: on 8.13.25

\-- Split Environment
\-- Standalone Lua interpreter (from Windows)
\-- Separate from CryEngine's Lua
\-- No direct engine access
\-- Missing game globals
\-- Different noscript loading paths

Unregistering and deleting luaapil.dll did nothing so I am at a loss.

Here is the basic use of this in pretty much any file which has a local dependency. As noted this works for pretty much everything, except the one file I depend on. I was only a day or two from being done. I also have no clue how any of the added code will function as a mod being added to other peoples games. For all I know Nexus could flag it bad content

local function LoadDependencies()

local success, error = pcall(function()

\-- Load in correct order

From here it is the normal actor data and parameters followed by all the functions
This is simply too much. I have been out of my depth of programming all summer using lua, cryengine and ripping apart the entire engine and putting it back together.

I would just like to go back and finish in my nice, simple fashion. I don't want to learn new stuff (I mean I do, but time is not on my side currently, so new stuff is not conducive to my college time).

So this is a "help me Obi-won Kenobi" moment.

Feel free to laugh :)

Trying to edit LUA of a UASSET file in Unreal Engine

I am trying to delete a block of code from a LUA noscript that's in an abandoned mod for Oblivion Remastered. It's causing a UI bug that results in the game crashing or locking up keyboard commands so you have to force close it. It's just for personal use I don't plan on uploading to Nexus or whatever.

I've unpacked the files (*.uasset), I looked at what I need to edit in FModel, I downloaded Epic Launcher / Unreal Engine and launched it, I downloaded the github version of LuaMachine. And that's about it, I have no idea what to do from here to get this thing open so I can delete what I need to then I can go repack it and use it finally.

Is there way to perform calculations on GPU ?

I recently watch video "Simulating Black Hole using C++" and near the end of the video author started to use .comp files to perform movement calculations of rays. I know that you can use .glsl and .vert with love2d, but those are for displaying graphics. So my question is can you use Lua with GPU for calculation purpose ?

I'm using Windows 11, VSCode, and MSYS2 UCRT64. I tried downloading the compiled Win64_mingw6 library version and added the following lines to my CMakeLists.txt file:

targetincludedirectories(test-bg PRIVATE
${CMAKESOURCEDIR}/liblua35/include
)
targetlinklibraries(test-bg PRIVATE
${CMAKESOURCEDIR}/liblua35/liblua53.a
