Howdy and welcome! Take a seat and grab a drink. There you go. So, you say you want to learn all about this old-fashioned 2D stuff in that new-fangled Unity game engine? Well, you've come to the right place. Er, book. This here book? It's all about using those awesome 2D updates that Unity added in v4.3 to make an entire game. Yup, a whole, basic platformer, complete with parallax scrolling, enemy logic, UI, and a boss battle. Pretty sweet deal, eh?
Chapter 1, Introduction to the 2D World of Unity, covers the basics of getting Unity up and running for 2D games and setting up a simple, animated, sprite-based player character.
Chapter 2, It Lives!, is all about camera control, 2D triggers, player death and resurrection, firing a weapon, and a bit about state machines for good measure.
Chapter 3, No Longer Alone, adds enemies! Shoot them, get killed by them, and watch them patrol. It's a party where everyone wants to kill you!
Chapter 4, Give It Some Sugar, shows you how to build dynamic, endless enemy generation and a bigger game world, introduces parallax scrolling, and adds a scoring system.
Chapter 5, The Ultimate Battle of Ultimate Destiny, lets you know that the enemies have a friend, and he's angry! In this chapter, you will build an entire boss battle.
Chapter 6, The Finishing Touches, is exactly what it sounds like—the final gravy on this awesome mountain of 2D goodness. You'll be adding in game rounds and a start screen.
This book is intentionally developed for only those who need one piece of software—Unity 4.3 or newer. That's it. Don't have Unity? No worries, you can nab a free version of this most excellent game engine from www.Unity3D.com.
This book is ideal for anyone who wants to learn how to build 2D video games or wants to expand their knowledge of the Unity game engine. To get the most from this book, having knowledge of C# and Unity is important, however, if you are less experienced in these areas, this book still gives you all the necessary tools to create your own game.
In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.
Code words in text are shown as follows: "Import the image labeled Platform.png."
A block of code is set as follows:
case PlayerStateController.playerStates.idle:
playerAnimator.SetBool("Walking", false);
break;
case PlayerStateController.playerStates.left:
playerAnimator.SetBool("Walking", true);
break;
New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "To do this, select playerSpriteSheet in the Project tab and look over at the inspector."
