Unity UI Cookbook

Overview of this book

With the increasing interest in game development, it's essential to design and implement a UI that reflects the game settings and shows the right information to the player. The Unity system is used to create complex and aesthetically pleasing user interfaces in order to give a professional look and feel to a game. Although the new Unity UI system is powerful and quite easy to use, by integrating it with C# scripts, it's possible to realize the potential of this system and bring an impressive UI to games. This guide is an invaluable collection of recipes if you are planning to use Unity to develop a game. Starting with the basic concepts of the UI components, we’ll take you all the way through to creating complex interfaces by including animations and dynamics elements. Based on real-world problems, these recipes will start by showing you how to make common UI elements such as counters and healthbars. You will then get a walkthrough of how to manage time using timers, and will learn how to format them. You will move on to decorating and animating the UI elements to vivify them and give them a professional touch. Furthermore, you will be guided into the 3D UI world and into HUD scripting. Finally, you will discover how to implement complex minimaps in the interface.

Creating a health bar with armor


In this recipe, we are going to create a health bar, similar to the one in Implementing a linear health bar recipe, but there is an armor that protects the player. In fact, if the player is attacked, he or she will first lose the armor, then the health. To achieve this, we will use multiple Image (Script) components, both for the health bar and for the pieces of armor, and develop a script to manage the entire logic.

How to do it...

  1. To begin, let's create an image, so right-click on the Hierarchy panel and then UI | Image, and rename it HealthBar with Armor.

  2. Let's change Fill Method into Horizontal and Fill Origin into Left. Of course, we need to add the Healthbar that we have just created to Source Image. Finally, we can place the Healthbar with Armor everywhere we want, always using the Rect Tool.

  3. In order to keep its original proportion, you can click on the Set Native Size button in the Inspector.

  4. Next, right-click on Healthbar with Armor and add a new image...
