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.

Showing the slider value as a percentage


Sliders are used a lot in video games. As a result, we have to display some percentage of the slider to give the player a better visual idea of what he is changing. For example, when the player is tweaking an ability parameter, it could be useful if the amount remaining is displayed as a percentage. The goal of this recipe is to create a script that shows the value of the slider in percentage. As such, we will develop a script that will use both the Slider (Script) and Text (Script) components.

How to do it...

  1. First of all, we need to create a new UI text to display the value of our slider in percentage. Therefore, we can right-click on the Hierarchy panel and then click on UI | Text. Rename it to Slider Shower. Furthermore, to customize the look or suit our needs, we can change Font and Font Size as well.

  2. Now, we need a script that receives the value of the slider, as data, which we will learn how to do later, and then show it as a number in percentage...
