Lua Learning - Roblox Basics

Lesson 1: Introduction to Lua Syntax

In this lesson, we'll cover the basics of Lua, the scripting language used in Roblox Studio. Lua is simple and powerful, making it perfect for game development!

Key Concepts:

Variables: Used to store data.
Functions: Reusable blocks of code that can perform actions.
Conditionals: Making decisions in your code.
Loops: Repeating actions multiple times.

Example: Below is a simple Lua script that prints a message:


-- Simple Lua Script Example

local message = "Hello, Roblox!" -- Define a variable
print(message)  -- Output the message

Lesson 2: Variables

In Lua, variables are used to store values that you can reuse in your code.

Example: Below is a simple script that defines a variable and outputs its value:


-- Variables in Lua

local myName = "Max"  -- Store a name in a variable
print(myName)  -- Output the value of myName

Lesson 3: Functions

Functions are blocks of code that you can call to perform an action. They allow you to reuse code and keep things organized.

Example: Below is a function that prints a greeting message:


-- Functions in Lua

local function greet(name)
    print("Hello, " .. name)  -- Concatenate the greeting with the name
end

greet("Max")  -- Call the function

Lesson 4: Conditionals

Conditionals allow you to make decisions in your code, such as checking if a condition is true or false.

Example: Below is a conditional that checks if a player’s health is above a certain value:


-- Conditionals in Lua

local health = 50

if health > 40 then
    print("You are in good health!")
else
    print("You need to heal!")
end

Lesson 5: Loops

Loops allow you to repeat an action multiple times. You can use them for tasks like iterating over items or repeating a block of code.

Example: Below is a loop that prints numbers from 1 to 5:


-- Loops in Lua

for i = 1, 5 do
    print(i)
end
