Just started learning - could use some help explaining some things

I have little experience in languages like Python and Java but wanted to learn Lua to make Roblox noscripts along with 2D games. I want to start off by just learning Lua as a whole. I've been learning for the past 3 days now (7 hours coding, and about 2 hours watching videos). Something that I'm struggling to get is the for and repeat loop, along with tables.

for a for loop the only thing I can do/make is:

for i = 1, 10 do
print("Hi.")
end

for tables, I try to make word-guessing games, or guess the length of a word but always have issues calling it from the table

local words = {
    "Dog", "Wire", "Mountian", "Tree", "House", "Car", "Bike", "Plane", "Boat",
    "Train", "Donkey", "Cat", "Fish", "Bird", "Lion", "Tiger", "Bear", "Wolf", "Fox", "Rabbit", "Horse",
    "Cow", "Pig", "Sheep", "Goat", "Chicken", "Duck", "Goose", "Turkey", "Penguin", "Ostrich", "Eagle", "Hawk",
    "Falcon", "Owl", "Parrot", "Crow", "Raven", "Seagull", "Dove", "Sparrow", "Robin", "Bluejay", "Cardinal", "Woodpecker",
    "Hummingbird", "Swan", "Pelican", "Flamingo", "Stork", "Crane", "Heron", "Ibis", "Vulture", "Condor", "Albatross", "Puffin", "Pigeon", "Starling", "Nigger"
}

io.write("Select a letter: ")
local userLetter = io.read():upper()

local matchingWords = {}
for , word in ipairs(words) do
    if word:sub(1, 1) == userLetter then
        table.insert(matchingWords, word)
    end
end

if #matchingWords > 0 then
    print("Words starting with '" .. userLetter .. "':")
    for , word in ipairs(matchingWords) do
        print(word)
    end
else
    print("No words found starting with '" .. userLetter .. "'.")
end

Lua ressources for intermediate programmers

Hello,

I am a hobbyist programmer with an background in math and an interest in computer science.

I worked myself through "COMMON LISP: A Gentle Introduction to Symbolic Computation" which was great. The exercises were trickey but also great fun and I learned a lot .

Now I developed an interest in Lua and I am allmost through "Programming in Lua". It is a great book about lua, but not a programming course.

Can you recommand good didactic ressources about programming/computer science on an intermediate to advanced level, that use lua as an prgramming language?

So far I found

\- Lua programming gems

\- https://github.com/a327ex/blog/issues/30



That should keep me busy for a while, but I am wondering, if there are other interesting options.

Thanks in advance!

What are things lua is missing or needs to change that you'd like to see?

Currently, I'm working on a small project that transpiles a custom version of lua's syntax to original lua. I plan to make an extension for it to use in my projects.

Here's an overview of it. This is what the transpiler sees in terms of types.

Let me know, I'll gladly take suggestions! Specially on classes, I'm not sure how built in class would look.

Terminal don't print anything of my lua code. Where did i go wrong?

Hi! I'm here again. I'm checking my learn on lua making a code. This code verify if talent (TLT) and efforce (EFT) are true, and then change the variables to make then have the same level, hp, and xp, even though they work by different ways. Buut, i guess something is wrong, since terminal don't print nothing. Someone can help me? Thanks for attention :)

HP = 0
XP = 0
LV = 0
EFT = false
TLT = true
TT = 0

if EFT == true then
HP = HP + 20
TTpoints = 10
XPproductionVR = 2
elseif TLT == true then
HP = HP + 5
TTpoints = 5
XPproductionVR = 8
elseif EFT == true and TLT == true then
HP = HP + 25
TTpoints = 10
XPproductionVR = 4
end

function TTproduction()
TT = TT + TTpoints
end
function XPproduction()
XP = TT * XPproductionVR
end

if TLT == true then
LevelUpVR1 = 20
LevelUpVR2 = 40
LevelUpVR3 = 60
elseif EFT == true then
LevelUpVR1 = 40
LevelUpVR2 = 80
LevelUpVR3 = 120
elseif TLT == true and EFT == true then
LevelUpVR1 = 40
LevelUpVR2 = 80
LevelUpVR3 = 120
end

if XP < LevelUpVR1 then
LV = 0
elseif XP >= LevelUpVR1 then
LV = 1
elseif XP >= LevelUpVR2 then
LV = 2
elseif XP == LevelUpVR3 then
LV = 3
end

while LV < 3 do
TTproduction()
XPproduction()
end

if LV == 0 then
HP = 5
elseif LV == 1 then
HP = 10
elseif LV == 2 then
HP = 20
elseif LV == 3 then
HP = 30
end

print(HP, XP, LV)

Can someone please help me with my noscript?

I made a noscript for a game with chatgpt, it's basically 3 noscripts in one.

1-Caps Lock + Right Mouse Button + Left Mouse Button Rapid-Fire: This functionality is only activated when Caps Lock is on. It allows for rapid clicking when the right mouse button is held and the left mouse button is also held.

2-Right Mouse Button Toggles Right Shift: This noscript presses the Right Shift key when the right mouse button is pressed and releases it when the right mouse button is released. It operates independently of the other noscript's conditions.

3-Mouse Button Interactions: It handles mouse movements when the right mouse button is held, and the left mouse button is also held.

The issue is that when I press capslock so number 1 can work, the other two functions stop working. I need nr2 and 3 to always be active, but as soon as I turn on capslock for the rapid fire then only rapid fire works.

Here is the noscript but pasting it here messes up the formatting for some reason so here is also a screenshot how it looks like in the logitech ghub software: https://i.imgur.com/PiiaGfB.png

EnablePrimaryMouseButtonEvents(true)

function OnEvent(event, arg)
-- First Script: Caps Lock + Right Mouse Button + Left Mouse Button Rapid-Fire
if IsKeyLockOn("capslock") then -- Check if Caps Lock is enabled
if IsMouseButtonPressed(3) then -- If the right mouse button is held
repeat
if IsMouseButtonPressed(1) then -- If the left mouse button is held
repeat
PressMouseButton(1) -- Press left mouse button
Sleep(50) -- Speed of rapid-fire, adjust as needed
ReleaseMouseButton(1) -- Immediately release after pressing
until not IsMouseButtonPressed(1) -- Stop when left mouse button is released
end
until not IsMouseButtonPressed(3) -- Stop when the right mouse button is released
end
end

-- Second Script: Right Mouse Button toggles Right Shift (always active)
if event == "MOUSEBUTTONPRESSED" and arg == 2 then -- Right mouse button
PressKey("RSHIFT") -- Press Right Shift
return -- Exit here to avoid interference
elseif event == "MOUSEBUTTONRELEASED" and arg == 2 then
ReleaseKey("RSHIFT") -- Release Right Shift
return -- Exit here to avoid interference
end

-- Second Script: Mouse button interactions (always active)
if IsMouseButtonPressed(3) then
repeat
if IsMouseButtonPressed(1) then
repeat
MoveMouseRelative(0, 2)
Sleep(90)
until not IsMouseButtonPressed(1)
end
until not IsMouseButtonPressed(3)
end
end



Really hope someone can help me with this because chatgpt is messing it up.

How to write code to add a specific number to an existing value

This might be a very basic query, but I've gotta learn somehow. So let's say I have an address with a value of 1000, which in hex is 3E8. And I want to add 200 to it, which would be C8. Is it possible to write code that makes that happen? Something like :

BlobHP = 0x8086963

If ReadShort BlobGainsItem
add (C8) to BlobHP.

That probably hurt to read if you're actually good at this and I wouldn't actually write it like that, but I'm just trying to get the idea of what I mean across. Pls help if you know how.

hi, i am a complete beginner in both lua and programming in general. i was just wondering if there is a way to make a variable using for loops (as you can see i'm repeating the same loop multiple times)

sorry if this has been asked before, i didn't really know what to search for on google for my question, thanks!

Matching markdown tables (regex)

I have a Lua noscript that parses MediaWiki markdown tables. It works great for "flat" tables where the elements in a row are all inline and separated with double pipes, but I'm having trouble making a separate noscript to deal with tables with each field on a different line such as this:

|-
| Game ABC
|{{untested}} <!-- xefu -->
|{{untested}} <!-- xefu2 -->
|{{untested}} <!-- xefu3 -->
|{{untested}} <!-- xefu5 -->
|{{untested}} <!-- xefu11 -->
|{{untested}} <!-- xefu6 -->
|{{playable}} <!-- xefu7 -->
|{{untested}} <!-- xefu7b -->
|{{untested}} <!-- xefu2019 -->
|{{untested}} <!-- xefu2021a -->
|{{untested}} <!-- xefu2021b -->
|{{untested}} <!-- xefu2021c -->
| Name Here
| Notes Here
|-
| Another Game
|{{menus}} <!-- xefu -->
|{{untested}} <!-- xefu2 -->
|{{menus}} <!-- xefu3 -->
|{{untested}} <!-- xefu5 -->
|{{untested}} <!-- xefu11 -->
|{{menus}} <!-- xefu6 -->
|{{menus}} <!-- xefu7 -->
|{{menus}} <!-- xefu7b -->

|{{untested}} <!-- xefu2021a -->
|{{untested}} <!-- xefu2021b -->
|{{untested}} <!-- xefu2021c -->
| Names Here

|-

I'm interested in taking the info between two different |- as one entry.

I feel like I'm close, but having trouble since Lua doesn't seem to support lookahead or non-capture groups:

how to install luarocks on windows

I have done it before with the use of this installer, but I want to do it manually so I can customize stuff. The installer works, but it creates problems with my C++ installation.

Few requirements for the install:
Must be on a different hard drive with the packages also on that drive
Must not come with lua install as well. I want to use one I already have installed
Must like work or whatever

so how can i install it?


(also side note does it work with luau?)

[SOLVED] "legacy sigalg disallowed or unsupported" error when emailing with LuaSocket

I have been emailing from Lua for a long with with the code on [this page](https://stackoverflow.com/questions/11070623/lua-send-mail-with-gmail-account/11070674). After updating Debian to Bullseye I got the error in the noscript, which was not at all helpful. After a lot of digging, it turned out that it is related to newer versions of OpenSSL.

The fix is to change the line:

`sock = ssl.wrap(sock, {mode='client', protocol='tlsv1'})`

to

sock = ssl.wrap(sock, {mode='client', protocol='tlsv1_2'})

I’m posting this for people to find later.
