Code issues (LUA 5.1)

Using an old macro program in WoW. Having issues with this code, and i'm not a coder. It seems to be complaining about the random() and randomseed() commands. Plus it doesn;t like building indicies. I didn't write this, I pared down someone else's free macro code just to get something working to learn from.

I am limited to LUA 5.1 unfortunately. I'm guessing this code is much newer.

Any help would be appreciated. Thanks!

-- Initialize random seed for Lua 5.1
math.randomseed(os.time())

mountListGround = {
"Black War Bear",
"Purple Hawkstrider",
"Black War Wolf",
"Summon Charger",
"Traveler's Tundra Mammoth"
}

mountListFlying = {
"Green Proto-Drake",
"Blue Wind Rider",
"Albino Drake"
}

-- First run after reloading - getting indices
if not builtIndices then

mountListGroundIndices = {}
mountListFlyingIndices = {}
mountListWintergraspIndices = {}

for i = 1, GetNumCompanions("MOUNT") do
local id, name = GetCompanionInfo("MOUNT", i)
if tContains(mountListGround, name) then
tinsert(mountListGroundIndices, i)
if name ~= "Purple Hawkstrider" then
tinsert(mountListWintergraspIndices, i)
end
end
if tContains(mountListFlying, name) then
tinsert(mountListFlyingIndices, i)
end
if name == "Traveler's Tundra Mammoth" then
tundraIndex = i
end
end
builtIndices = true
end

-- Random CallCompanion alias

CallCompanion("MOUNT", indexTablemath.random(#indexTable))
end

What's the best way to learn Lua?

I'm new to Lua and I'd like to learn it. I have almost no experience with coding except for a bit that I learned from Roblox coding tutorials on Lua. I'd like to learn Lua 5.3, since I heard that Lua 5.4 has some drawbacks that are not good. I'd like to know the best way to learn Lua. I want to learn Lua, to where I can use it professionally and have the deepest understanding of it. I'm thinking after I'm done; I want to build games. I would appreciate any help with this. I'm thinking of learning it from YouTube tutorials like this one: (55) Crash Courses - YouTube, but I'd like to know what would work the best.

My new project: LuAssembly

I want to make machine code writing accessible and enjoyable for everyone. My idea is to create a "language" based on Lua's syntax, which will then be converted into an assembly (.asm) file using C++. Afterward, the NASM assembler will turn it into a binary (.bin) file. Does this sound like a good idea?

YMT FILES

Hello,

I'm seeking help with modifying .ymt files in Red Dead Redemption 2, specifically for RedM compatibility. Below is a portion of the binary code from a functional .ymt file that works in both story mode and RedM:

PSIN..RP.................".".............c+¡....................ëÁ᛬#.Ú................?€......................?€......ÿÿ................................

I successfully modified the player_three.ymt file, and while it works perfectly in story mode, the character becomes invisible in RedM. I suspect the file is likely becoming corrupted because it's not encrypted as RedM requires. Even OpenIV cannot open the corrupted version, flagging it as a corrupted file.

Any help or insight on how to properly encrypt .ymt files or make them compatible with RedM would be greatly appreciated.

Updates about my project: LuAssembly

I started making the lexer and the parser (On python, because I felt more comfortable to do it with), and I thought and realized that the language wasn't as "Lua-Like" as I initially intended. So I decided to rebrand i'ts name. Unfortunately, because of the subreddit rules, I won't be able to keep updating everyone here. The new name is... .FAST (Fast Assembly Source Translator). I'll post the Github link soon to keep everyone updated.

Is Lua stil used for ML

As a data scientist I knew at the back of my head that one of the most popular Python libraries in ML, PyTorch, started as a Lua package named Torch. It seems that since then the field left Lua completely and turned to Python, a bit of Julia and R, maybe Matlab and C/C++ for embedded stuff.

I came to Lua via Neovim a year ago. Using it, and enjoying it, made me wonder - are there any ML/DS people using Lua these days?

Where can I learn how to make a text based game?

I noscript in Roblox Studio, and I want to try to make a text based RPG in a Lua IDE, problem is that the only Lua stuff I know is purely from Roblox Studio, and thus I have no idea what to do.

JSON library for Reddit?

I'm experimenting with API on Reddit and used dkjson, but I got parsing errors. I don't get any errors with Go's native equivalent, so I assume that the very long/complex Reddit response might trigger a bug in dkjson. What alternative do you recommend? (luarocks has tons of them)

How to deobfuscate an MLO mod from FiveM?

I recently purchased an MLO mod and tried to make it work in GTA V singleplayer (it is a house mod) And after doing research, found out that it is being obfuscated and encrypted.

these are the contents of the folder:

fxmanifest.lua

.fxap

-tream

From my research, i would want to decrypt the manifest.lua? But when i open it with notepad or visual code, it just says this:

fx\_version 'cerulean'

game "gta5"

author 'brofx'

denoscription 'brofx\_mansion\_20'

version '1.1.2'

this\_is\_a\_map "yes"

dependency '/assetpacks'

Visual code will open the .fxap into this:

# FXAP �����6����� ڝA� ��6ӵ Q^Iq� �B)�� �<���8U�~�T�œ}X���⚗U%1��A ,�    n_�S���|w�k�U52 �~��.���v [0�C�3��C� �� �mO _� ��׌'�?��ӽ���Y٫ �4

# M�� � l\�T ��Qs�"�����{󓧵ߤn<



any way i can decrypt this to work in singleplayer?

i really want to play this in singleplayer and it cost a lot so i would be bummed out that i would not be able to get this to work. thank you all.



UPDATE: I found out that in order to decrypt, i must decrypt the .YDR files, im not certain where i would start or how different it would be to decrypt these .YDR files.

Need advice for Windows + Busted + GitHub workflows

I'm trying to setup a test matrix for Windows + Linux + MacOS for lua unitests, using busted

My best attempt so far is viewable here, I got lua + luarocks installed, I'm installing the test dependencies from my .rockspec file. But it fails to build. The only error I see in the log is Error: test suite failed. The line is in the middle of a bunch of logs and the noscript keeps running but ultimately fails with exit code 1.

I have some questions about this

1. Which dependency failed to run the test suite? From the log it looks like it's a package called say. Just want to make sure I'm reading this correctly.
2. Is an error like that generally ignorable? I could completely silence the error because I could silence something important later.
3. If you know of a working "(Windows + Linux + MacOS) * Busted * GitHub" I would love to see a link to it!
