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.

Developing a well-formatted countdown that changes


In this recipe, we are going to create a countdown that displays the time on the screen as minutes and seconds. However, to take this display a step further, as the time elapses, it will change color. Just as the radial timer graphically represents the time that passes, a colored numeric timer provides a similar function. For example, in moments during gameplay when there is intense action, a player may not necessarily have the time to focus on the timer, or he may actually lose track of the time that has elapsed. Whatever the case may be, another good way to indicate to the player the time as it is decreasing is through color. Therefore, as the player is engaged in gameplay, the color of the time can provide a quick indication of how close he is to running out of time. We will use the Text (Script) component and develop a script to achieve our goal.

How to do it...

  1. First of all, we need to create a new UI text to display our timer. To do...
