Courses, Training, and Other Resources


Are you interested in game development, or using a scripting language to make changes to a program without affecting its infrastructure? Lua, a scripting language born in Brazil (“Lua” is the Portuguese word for “moon”), may just be the technology for you.

If you are interested in working in game development or making changes to web pages, you should seriously consider learning Lua.

What is Lua?

Lua is a

scripting language

designed primarily for embedded use in applications and not meant to be used as a stand-alone language. Lua was designed in 1993 as a language for extending software applications to meet the increasing demand for customization at the time.

A scripting language like Lua, Python, and JavaScript can automate the execution of common tasks. Lua is cross-platform, which means that it can run on Windows, Mac, Linux, and iOS/Android operating systems.

Lua is often used for making games with the Love 2D Game Engine. Lua is used in popular games such as

Roblox

,

World of Warcraft

,

Angry Birds

, and

Civilization

. Lua has also been widely used by editors to make changes to Wikipedia pages.

What is Lua Used for?

Lua is lighter and smaller than other scripting languages like Python, which makes Lua attractive to developers. Being “light” and “small” refers to how much memory something takes up in your application. Generally, Lua adds less than 100 kilobytes to your application. Rather than working as a stand-alone language, Lua can be embedded into applications.

Lua is used in game development, including in games such as

World of Warcraft

. In

Warcraft

, you can use Lua to customize the game’s interface. There are even hackers in the game’s community that teach each other Lua. Lua is also used for building games in conjunction with game engines such as Love 2D and Corona.

But that’s not all. Lua is used in the Apache HTTP Server, a web server software; Celestia, which provides real-time 3D visualization of space; MySQL Workbench (the development environment used for the MySQL database); and Torch, a machine learning library based on Lua.

In 2013, Wikipedia announced that anyone can use Lua to build material on Wikipedia, Wikiquote, and Wiktionary. They created Scribunto, a MediaWiki extension to

allow editors to embed Lua scripts

to use with their templates. Templates include common elements like the infoboxes on many Wikipedia pages that include biographical information about a page’s subject.

Lua runs in a sandbox, which means that it is designed to not interfere with other code in the application. With Lua, you can limit how much CPU process time any one script can use. Both of these elements were factors in Wikimedia Foundation’s decision to use Lua.

Lua is also used in software such as Adobe Lightroom. You can

enhance and extend Lightroom’s capabilities

by building plug-ins with Lua with the Adobe Lightroom software development kit (SDK).

Learning Lua

Lua is a valuable skill to learn if you are interested in game development, but it is also useful in other cases where an embeddable scripting language is needed. Companies such as Shopify, Venmo, and Thumbtack

use Lua as part of their tech stack

.

As of this writing, there are over

500 job listings on LinkedIn

that mention Lua. These include jobs such as Performance Model Development and Analysis Engineer, Software Engineer-Rendering, and AR Tools Engineer.

Other popular languages for game development include C++, C#, Java, and Python. If you’re interested in a career in game development, combining Lua with these other programming languages can make you a competitive job candidate.

How Long Does It Take to Learn Lua?

It takes 2–3 days to learn the basics of Lua, and 3–4 weeks to know enough to use it professionally. Lua’s syntax is simple and fairly easy to learn. Lua is “strongly typed”, which means that it is consistent and predictable.

Lua has its own libraries (a library is a collection of pre-built code), and

you can extend Lua with libraries from other languages

, such as C.

How to Learn Lua: Step-by-Step

There are different approaches you can take when learning any new technology. Here are some steps we recommend for learning Lua:


  1. Discover how Lua is used.

    Research some of the companies and industries Lua is used, such as game development.

  2. Read about Lua.

    There are books available to help you learn this scripting language, such as the free

    Programming in Lua

    , written by Lua’s creators and available on the

    official Lua website

    .

  3. Try out the



    Lua Demo



    .

    Before you decide whether you want to install Lua on your computer, you can see what the syntax looks like with this demo.


  4. Install Lua



    .

    When you’re ready to download Lua on your computer, you can do so on the official Lua website. You can use an IDE (integrated development environment) such as

    ZeroBrane Studio

    to code with Lua.

  5. Practice your skills.

    Check out tutorials such as

    “Getting Started with Lua”

    from Game Dev Geek.

  6. Get involved in the



    Lua community



    .

    On the official Lua website you can learn about the Lua community’s Discord room, forum, and StackOverflow tag.
