- Lua is a high level, cross-platform programming language that can be embedded in various software products. For example, Lua is used as a scripting language inside of popular networking software tools including Wireshark and nmap. Lua has also been used to script actions inside of games such as Roblox.
Similar to other high level languages, Lua uses a "virtual machine" layer to interpret instructions, and handle memory management (garbage collection).
In this video, we will be taking a look at how to write Lua code completely from scratch. After watching this video, and practicing some of the code samples, you should be equipped to write Lua code yourself. You should install the development tools that we present in this video, including Microsoft Visual Studio Code, and the Lua and Code Runner extensions for VSCode.
Lua probably isn't the best choice for general purpose programming, although it could be used for that purpose if you chose to. Even though Lua doesn't support the notion of structs and classes, you can still construct custom types of objects by using the "table" data type.

Crazy..
yoo
Its only 2 Months ago (the vid)
I watched the whole video. Great and Smooth! Keep up the good work :))
The quality of your video is amazing, and you are such a good teacher.
i'm still at half of the course but i hope there will be more of lua !
thanks alot !
this video was such a great finding!
I've been learning lua myself by trial and error, and I got stuck not knowing how to structure my code properly.
(ah, so that's how Lua modules work!)
thanks a lot for your time and valuable info. you are an amazing teacher.
Hi Trevor ! It's a very awesome topic, because I'm going to learn Lua to configure NeoVim😆
Dawg same it’s been about two weeks since I started my nvim config ☠️
Same here :) need to improve my config
Good to see you back ;)
Thanks! Glad to be back. I've been posting AWS + Rust videos over on the StratusGrid RUclips channel. Make sure to follow that! 🦀🦀
Thank you for this, it would be nice if you could do Luau also, its like a Typescript version of Lua that is being use by Roblox
I feel there's not many informative, in-depth videos on YT about Lua; specially for OOP.
(I know that's not Lua's strongest suit but, in the environment I'm currently working in, it's either Lua or C)
if you ever have the time to tackle more advanced concepts like how to use Lua modules to do composition or how to make use of mixins with Lua, that would be wonderful.
either way, you've got a new subscriber!
This is great!
I use Lua in an audio/visual/control system called QSYS by the audio company QSC. Lua is used to control automation, build plugins to connect to other devices or extend stock functionality of the system.
This video is helpful for me to fill in some gaps, where I sometimes find it difficult to read the manual, having someone explain it in a different way is awesome. Much appreciated!
That's exactly why I created this video! To help round out people's knowledge of the language in an easy to understand video form. I'm so happy that this helped you! That's a really interesting use case for Lua as well. Thanks for sharing the software package name that you are using!
12:29 you are able to install Lua through Homebrew with `brew install lua`
Огромное спасибо!
Пожалуйста! Спасибо, что смотрите мой канал!
Hi Trevor, which theme are you using in the video? I like your purple theme.
Hey there! It's the Outrun theme by "samrapdev" in the VSCode Marketplace.
@@TrevorSullivan great, thanks!!
Hey, Just learning lua (programming in general as im trying to make a FiveM server) and my output says :
'lua' is not recognized as an internal or external command, operable program or batch file."
every time I CTRL + Alt + N sorry if this is a stupid question to ask but would you know why this is happening??
just to add onto this my:
"local" is dark blue instead of purple like yours
"last_name" is light blue instead of white
*name* is orange instead of blueish/purple
""print" is light yellow instead of orange
@@JMiiahYT the colors can be customized to whatever you want in your terminal. Those don't matter at all.
Usually you'll get the error about Lua missing because it's not in your PATH environment variable. There's tons of videos and articles that talk about this fundamental concept, so I'd recommend checking those out. The alternative to adding the Lua directory to "PATH" is to call it using the full filesystem path (ie. C:/Lua/lua.exe)
when i use the run code command in the promt and execute it it says "lua' is not recognized as an internal or external command,
operable program or batch file.
That's usually because it's not in your shell's PATH. How did you install it? You'll need to find the Lua binary and specify the full or relative path to it.
can you make Advance lua tut sir?

And various entirely non useful things like my game mods 😂
And it is like Java imo. It and HTML are the only languages of any kind even had passing knowledge of before picked up Lua to mod the total wars games beyond texture swapping etc. It felt familiar to me, and wasn’t until dipping my toes into other programming languages, let’s say more mature languages, that I realized how they differ.
Time stamps please
Make more videos on rust
I will!
