Unity 4.x Game Development by Example: Beginner's Guide - Third Edition

By: Ryan Henson Creighton

Overview of this book

Unity is one of the biggest game engines in the world, providing the user with a range of important tools that they need to bring their ideas into reality. Beginner game developers are optimistic, passionate, and ambitious, but that ambition can be dangerous! Too often, budding indie developers and hobbyists bite off more than they can chew. Games like Angry Birds, Cut the Rope, and Fruit Ninja are fun, simple games that have delighted players and delivered big profits to their creators. This is the perfect climate for new game developers to succeed by creating simple games with Unity, starting today. This book teaches you the ins and outs of the unique Unity game engine interface. Clear and concise code examples written in both Unity Javascript and C# take you through the step-by-step process of building five small, functional games. With this understanding you can start making your own mark on the game industry! With absolutely no programming or game development experience, you will learn how to build five simple games in Unity by following step-by-step instructions, peppered with amusing analogies and anecdotes from an experienced indie developer. Following a primer on simplifying your game ideas to that single “something” that keeps players coming back for more, dive into the Unity game engine by creating a simple bat-and-ball game. From there, you'll build a complete memory game using only the Unity GUI system. After building a 2.5D mouse avoider game, you'll learn how to re-skin the project to completely change the game's theme. Incorporating everything you've learned, you'll return to complete the bat-and-ball game by adding scoring, replay flow, sound effects, and animations. Finally, in the new bonus chapter, you'll program some simple AI (Artificial Intelligence) for a tic tac toe game. "Unity 4.x Game Development by Example" is a fun and light-hearted exploration of one of the most powerful game engines on the market today. Find out what all the fuss is about by getting up to speed using this book!

Time for action – the point of impact


We're finished tweaking the explosion, so you should delete the instance of the Explosion Prefab from the Scene view. The original stays safe and sound in the Prefab container in your Project panel. Naturally, we want this explosion to appear whenever we detect that the bomb has hit the ground. We've already put the logic in place to detect a ground hit—remember that we're moving the bomb back up into the sky as soon as it drops below ground level. So it should be a reasonable hop, skip, and jump towards making that explosion happen. And luckily, it is!

  1. Open up your Bomb Script and add the following variable at the very top:

    var prefab:GameObject;
    
  2. Then, just after the code where we detect a ground hit, add this line:

    if(transform.position.y < 0)
    {
      Instantiate(prefab, transform.position, Quaternion.identity);
    

We created a variable called prefab at the top of the script to store some sort of GameObject. Note that small-p "prefab" is not a Unity keyword...
