Chapter 1, Core UI – Messages, Menus, Scores, and Timers, is filled with UI (User Interface) recipes to help you increase the entertainment and enjoyment value of your games through the quality of the interactive visual elements. You'll learn a wide range of UI techniques, including updatable text and images, directional radars, countdown timers, and custom mouse cursors.

Chapter 2, Inventory GUIs, shows you how many games involve the player-collecting items, such as keys to open doors, ammo for weapons, or choosing from a selection of items, such as from a collection of spells to cast. The recipes in this chapter offer a range of text and graphical solutions for displaying inventory status to the player, including whether they are carrying an item or not, or the maximum number of items they are able to collect.

Chapter 3, 2D Animation, includes powerful 2D animation and physics features. In this chapter, we present recipes to help you understand the relationships between the different animation elements in Unity, exploring both the movement of different parts of the body and the use of sprite-sheet image files that contain sequences of sprite frames pictures.

Chapter 4, Creating Maps and Materials, contains recipes that will give you a better understanding of how to use maps and materials with Unity 5's new Physically Based Shaders, whether you are a game artist or not. It is a great resource for exercising your image editing skills.

Chapter 5, Using Cameras, explains recipes covering techniques for controlling and enhancing your game's camera. This chapter will present interesting solutions to work with both single and multiple cameras.

Chapter 6, Lights and Effects, offers a hands-on approach to a number Unity's lighting system features, such as cookie textures, Reflection maps, Lightmaps, Light and Reflection probes, and Procedural Skyboxes. Also, it demonstrates the use of Projectors.

Chapter 7, Controlling 3D Animations, focuses on character animation, and demonstrates how to take advantage of Unity's animation system — Mecanim. It covers a range of subjects from basic character setup to procedural animation and ragdoll physics.

Chapter 8, Positions, Movement and Navigation for Character GameObjects, presents a range of directional recipes for computer-controlled objects and characters, which can lead to games with a richer and more exciting user experience. Examples of these recipes include spawn points, checkpoints, and waypoints. It also includes examples that make groups of objects flock together, and the use of Unity NavMeshes for automated path-finding over terrains and around obstacles.

Chapter 9, Playing and Manipulating Sounds, is dedicated to making sound effects and soundtrack music in your game more interesting. The chapter demonstrates how to manipulate sound during runtime through the use of scripts, Reverb Zones, and Unity's new Audio Mixer.

Chapter 10, Working with External Resource Files and Devices, throws light on how external data can enhance your game in ways such as adding renewable content and communicating with websites. The chapter also includes recipes on automating your builds with Unity Cloud, and how to structure your projects, so they can be easily backed up using online version control systems such as GitHub.

Chapter 11, Improving Games with Extra Features and Optimization, provides several recipes with ideas for adding extra features to your game (such as adding slow motion and securing online games). Many other recipes in this chapter provide examples of how to investigate and potentially improve the efficiency and performance of your game's code.

Chapter 12, Editor Extensions, provides several recipes for enhancing design-time work in the Unity Editor. Editor Extensions are scripting and multimedia components, that allows working with custom text, UI presentation of the game parameters, data in the Inspector and Scene panels, and custom menus and menu items. These can facilitate workflow improvements, thus allowing game developers to achieve their goals quicker and easier.

All you need is a copy of Unity 5.x, which can be downloaded for free from http://www.unity3d.com.

If you wish to create your own image files for the recipes in Chapter 4, Creating Maps and Materials, you will also need an image editor, such as Adobe Photoshop, which can be found at http://www.photoshop.com, or GIMP, which is free and can be found at http://www.gimp.org.

This book is for anyone who wants to explore a wide range of Unity scripting and multimedia features, and find ready-to-use solutions for many game features. Programmers can explore multimedia features, and multimedia developers can try their hand at scripting.

From intermediate to advanced users, from artists to coders, this book is for you, and everyone on your team!

It is intended for everyone who has the basics of using Unity, and a little programming knowledge in C#.

In this book, you will find several headings that appear frequently.

To give clear instructions on how to complete a recipe, we use these sections as follows:

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, folder names, filenames, file extensions, pathnames, and user input are shown as follows: " For this recipe, we have prepared the font that you need in a folder named Fonts in the 1362_01_01 folder."

URLs are shown as follows: Learn more about the Unity UI on their manual pages at http://docs.unity3d.com/Manual/UISystem.html.

A block of code is set as follows:

  void Start (){
    textClock = GetComponent<Text>();
  }

  void Update (){
    DateTime time = DateTime.Now;
    string hour = LeadingZero( time.Hour );
    string minute = LeadingZero( time.Minute );
    string second = LeadingZero( time.Second );

    textClock.text = hour + ":" + minute + ":" + second;
  }

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "In the Hierarchy panel, add a UI | Text GameObject to the scene – choose menu: GameObject | UI | Text."
