Watching for possible gotchas while creating script files in Unity Fixing synchronization if it isn't working properly Adding our script to GameObject Lots of files can create a mess Why does my Project tab look different?

Instance? What is this? Summary

Introducing the Building Blocks for Unity Scripts

Understanding what a variable is and what it does

Naming a variable A variable name is just a substitute for a value Creating a variable and seeing how it works

Declaration Assignment

Click Play! Changing variables Watching for a possible gotcha when using public variables

What is a method?

Using the term "method" instead of "function" Method names are substitutes, too

Introducing the class

Inheritance

The Start(), Update(), and Awake() methods, and the execution order Components that communicate using dot syntax

What's with the dots?

Making decisions in code

Using the NOT operator to change the condition Checking many conditions in an if statement Using else if to make complex decisions Making decisions based on user input

Pencil and paper are powerful tools Summary

Getting into the Details of Variables

Writing C# statements properly Understanding component properties in Unity's Inspector

Variables become component properties Unity changes script and variable names slightly

Changing a property's value in the Inspector panel

Displaying public variables in the Inspector panel

Private variables Naming your variables properly Beginning variable names with lowercase Using multiword variable names Declaring a variable and its type

The most common built-in variable types

Assigning values while declaring a variable Where you declare a variable is important Variable scope - determining where a variable can be used Summary

Getting into the Details of Methods

Using methods in a script Naming methods properly

Beginning method names with an uppercase letter Using multiword names for a method Parentheses are part of the method's name

Defining a method the right way

The minimum requirements for defining a method

Understanding parentheses - why are they there? Specifying a method's parameters

How many parameters can a method have?

Returning a value from a method

Returning the value

Example

Summary

Lists, Arrays, and Dictionaries

What is an array?

Declaring an array

Storing items in the List

Common operations with Lists

List <T> versus arrays Retrieving the data from the Array or List<T>

Checking the size

ArrayList Dictionaries

Accessing values How do I know what's inside my Hashtable?

Summary

Loops

Introduction to loops The foreach loop The for loop

An example

The while loop while versus for loops Loops in statements Modulo Searching for data inside an array Breaking the loop Summary

Object, a Container with Variables and Methods

Working with objects is a class act

A few facts Example

Instantiating an object Bored yet? Using methods with objects Custom constructors Overloading Summary
