Course description

This is a comprehensive course dedicated to the language Lua, one of the world's favorite scripting languages. Lua is fast, small, and super easy to integrate with C and C++, which makes Lua an excellent choice to extend and script compiled C and C++ applications.

This course is divided in three parts:

lua language tutorial

1. The first part is a beginner-friendly journey into the building blocks of the Lua language. We'll start from the very beginning and look at things like variables, expressions, conditionals, loops, functions, tables, object-oriented programming, functional programming, and other popular tools and modules of Lua.

lua language c api

2. The second part is aimed at intermediate-experienced developers that want to learn how to integrate Lua with their native C or C++ projects. We'll put our C-programmer's hat on and review how to embed the Lua programming language inside a compiled application using the powerful Lua C API.

3. The third and last part is a series of short bonus lectures. These lectures will explain how the Lua language is used inside Roblox Studio. Roblox is an example of a popular game engine that uses a dialect of Lua as its main scripting language.

The tools you'll need

All you need is a Lua interpreter. The official Lua tools are all cross-platform, which means you'll be able to code along on either Windows, macOS, or Linux!

Is this course for you?

This course has no prerequisites. We'll cover the official Lua language from the ground up, so even beginners with no prior experience in coding are welcome to join!

This is not a course about creating Roblox games! Our main focus is Lua, the programming language.

How is this course different?

This is a complete immersion in the world of Lua! We'll learn how to think like Lua programmers, carefully covering the syntax and the most popular modules from Lua.

lua game scripting

Differently than most Lua resources out there, this course also covers the integration of Lua with native C and C++ code! We'll learn to work with the Lua C API to embed the Lua language inside a C project, exposing Lua to be used as a proper scripting language.

"AMAZING. I'm not games programmer, but I'm really impressed about the concepts explained and also the power of LUA Scripting Language. I think that Roblox topic demands some experience playing Roblox and also concepts of games programming."
