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 slide shower using a discrete slider


Here, we can go further in providing additional customization for the player. In this case, we are going to implement a slide shower. The player will be able to scroll between pictures using a slider. To achieve this, we will see how to write a script to run this system. Again, we will use the events from the Slider (Script) component.

How to do it...

  1. To begin, we need to create our slider, which will be the controller of the player, so let's right-click on the Hierarchy panel and then go to UI | Slider. Finally, rename it to SlideShowerSlider.

  2. Then, select the slider and, in the Inspector, navigate to Add Component | New Script. Name it to SlideShowerScript and then click on Create and Add.

  3. Now, double-click on the script in order to edit it. Like every other time when we deal with the UI, we have to add the using UnityEngine.UI; statement at the beginning of the script, since we are going to use some UI classes.

  4. We need two public variables, one...
