How to learn Lua

I know the basics of Lua but don't know how to proceed. Any tips?

Wanted to share my Lua game engine with VS Code breakpoint debugging (Made in C++)

The Editor

The engine could be used as learning material for the beginners on this forum. If you're doing a C++/OpenGL/Lua engine, feel free to have a look. It should be fairly straight-forward to compile and run a template project.

Feature Set, TL;DR

Editor with all kinds of tools.
Works on all desktop platforms (Win, Linux, Mac) and browsers (WebGL 2 / WebAssembly).
PBR Renderer (OpenGL ES 3.0), point lights, sun light, skybox, MSAA, material editor...
Lua Scripting for systems or components, with breakpoint debugging in VS Code.
Object/Component System (like Unity), support C++ components or Lua components.
Serialization (save/load) of all the things (scene, materials, prefabs...)
In-Game User Interface
Multi-threaded animation system, root motion, etc
Audio
Multi-threaded job system
3D physics (bullet3): rigidbodies, raycasts, etc
Networking: scene sync, events, client/server architecture, multiplayer debug tools, UDP, etc

If anyone has questions, please reach out :D

Lua 5.3.0, os.time(), and year 2038

I'm using Lua 5.3.0 for a project and someone on my team raised concerns about the year 2038 issue. If I set the date to Jan 19.2038 22:30:00, I get the following error when I run os.time() from Lua: "time result cannot be represented in this Lua instalation" (the misspelling of 'installation' was apparently fixed in 5.3.1).
os.date() seems to work correctly, though.
Does a newer version of Lua have a fix for os.time(), or do I need to rework my code to utilize os.date() instead?

What would be the most optimized way to add commas to big numbers?

I'm doing a mod for a game and for more dynamic score display I have a function that makes it quickly catch up to the real hidden score over 5 seconds and is called 20 times/s, but since the number eventually reaches up to 10mil I want to add commas for better readability. Solutions I've found on the internet run too slow and it takes 15 or more seconds to catch up instead.

Majordome v4 released

Majordome is an events based automation tool using timers and MQTT messages arrival. Your application itself is a galaxy of small Lua tasks (as AWS' Lambda is doing).

Technically, Majordome is a C++ massive multitasking/multithreading framework, providing all the tools needed to orchestrate those tasks in an efficient and resources conservative way. Tasks are running in stateless environments, but data can be shared among them using MQTT messaging, data collection and shared variable.

This new version provides :
- ability to extend using loadable module
- a comprehensive documentation
- migration to Séléné v7

Using the LuaSocket library inside DeSmuME

Hi, I'm trying to use the LuaSocket library ([docs](https://lunarmodules.github.io/luasocket/), [repo](https://github.com/lunarmodules/luasocket)). Since I'm working within the DeSmuME Lua noscripting environment, I'm restricted to the following:

* Can't use LuaRocks installer
* Lua 5.1
* 32-bit libraries

I found [this discussion](https://github.com/lunarmodules/luasocket/issues/283), the guy has the same use case as me (but for 64-bit) but didn't explain exactly what he did. I'm on Windows 11. I have to use 32-bit (x86) DeSmuME as my noscript uses another library that requires it.

I found [this repo](https://luarocks.org/modules/luasocket/luasocket/2.0.2-1) containing a 32-bit LuaSocket source. The 'win32-x86' link on that page downloads a file that extracts to a collection of .lua files and some .dll files. Previously when I've needed to import a library I just 'require' something in my Lua noscript but I don't know what I should do here. Probably there are some other steps too, but I barely know anything about this so I'm a bit stuck! :(

Screenshot of contents of the above

[File directory of the win32-x86 folder in the above link](https://preview.redd.it/pzfm3ulwhl5d1.png?width=263&format=png&auto=webp&s=d5f834746f91f3dfb711b12708c10ba052ba3a95)

Would anyone be able to explain how I can install this library for my situation? Thanks for any guidance.

Rotating a Drone Blade

Hi there, I'm trying to program a drone blade to rotate (around the z-axis) in Visionary Render using Lua, but I have no experience in how to code a rotating assembly. The blade is locked in all position directions and in x and y rotation directions. I need help writing a noscript to execute when a button is pressed that then starts turning the blades (doesn't have to be fast, just has to look like they're turning).

Any help would be greatly appreciated :)

Need Help with FiveM Script - AI Responds in Console but Not in UI

Hi everyone,

I'm working on a FiveM noscript that integrates an AI-powered NPC chat system using QBCore. The goal is for players to be able to approach NPCs, press "E" to interact, and have a conversation where both the player's messages and the NPC's AI-generated responses appear in a UI chat window.

The issue I'm facing is that while the AI responses are correctly generated and logged in the console, they do not appear in the UI in the game. The player's messages show up in the UI chat window, but the NPC's responses are missing.

Here's a brief overview of my setup:

1. **Server Script (**`server.lua`**):** Handles the AI API request and sends the response back to the client.
2. **Client Script (**`client.lua`**):** Sends the player's message to the server, receives the AI response, and sends it to the NUI.
3. **UI Scripts (**`index.html`**,** `style.css`**,** `noscript.js`**):** Manages the chat window and displays messages.

I tried everything but nothing worked.

If you wanna test it guys, just create an access token on huggingface and add it to the config.lua.

here is my Code:

Could someone help me out with patching this mod?

I am new to lua coding, and I'm stuck on patching this mod. I'd like to patch "targetLevel = 0.0 + targetLevel - ((UKO.randomDecimal(maxToLose / 10)) / 10 \* targetLevel)" to make it remove a consistent percentage value. Instead of removing a random value like it does currently!

 
  if hasConfig then
        local oldTargetLevel = 0.0 + targetLevel
        if chanceToLose ~= 0 and UKO.random(chanceToLose) then
            targetLevel = 0.0 + targetLevel - ((UKO.randomDecimal(maxToLose / 10)) / 10 * targetLevel)
            if targetLevel == oldTargetLevel and oldTargetLevel ~= 0 then --if we somehow rolled no change, not even a fractional loss, and we're not at zero..
                targetLevel = targetLevel - UKO.randomDecimal(1) --you're not getting away that easily..
            end
            print("UKO: Randomized loss has left the new target at "..targetLevel)
            if (oldTargetLevel - targetLevel > 0) then
                if affectedPerks ~= "" then
                    affectedPerks = affectedPerks..", "
                end
                affectedPerks = affectedPerks..perkName
            end
        end

It's so hard to implement a shooting feature for the player, probably 'cause it will share a touch with the movement and move and shoot where you clicked. It's really hard to explain LOL, but I just want to be able to implement a move and shoot independently feature. Any suggestions? Thanks in advance.

Edit: I just realised how butchered the code looks on reddit, I don't know how to properly write code snippets though :(
