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.

For instance, when we want to display the proximity of an object or a character, a visual displayer or even an auditory distance displayer can give us a better indication of how far or close we are from a particular thing. This is done in order to assist us during gameplay, for example, to avoid a particular enemy, or not enter a dangerous region of a game.

How to do it...

  1. To begin, we have to create a UI image that will be our distance displayer. Right-click on the Hierarchy panel, then go to UI | Image, and rename it DistanceDisplayer. Of course, it is possible to resize the image, change Source Image, and then place it as we wish in Canvas.

    Tip

    We are going to change the color of the Image (Script) component. However, in order to avoid color distortion on our HUD component, we should make Source Image completely white, with the form of the part we want to change...
