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.

Implementing a linear health bar

In this recipe, we are going to create a linear health bar. The health of the player will be displayed as a bar that shortens when the player's health decreases, and extends with the player's health increases. To achieve this, we will use the Image (Script) component in a different way than what we have in previous recipes, and develop a script to manage the length of the bar.

How to do it...

First of all, we need to create our health bar, so let's open a graphic program and create it. We can create something that should looks like the following:
Then, import it in to our project. If the project isn't set to 2D, remember to set the Texture Type of the imported image to Sprite (2D and UI), and then click on Apply.
Next, create a new Image. Right-click on the Hierarchy panel and then UI | Image, and rename it to Linear Healthbar.
Inside the Image (Script) component, we have to change Image Type into Filled. The component should change a little bit in the Inspector...
