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 linear timer


In this recipe, we are going to create a linear timer. In this instance, the timer is shown as a long bar that shortens over time. An example of this would be when we want a player to make a decision within a short period of time, such as during a dialog choice to progress the narrative. In this case, the timer may feature above or even below the choices to indicate the amount of time that the player has left to decide. To achieve this, we will use the Image (Script) component and develop a script to manage the length of the bar according to the time remaining.

How to do it...

  1. First of all, we need to create a bar for our timer. To do this, we can open a graphics program to create it. Alternatively, we can just use the bar that we created in the Implementing a linear heath bar recipe in the previous chapter.

  2. Next, we need to import the bar into our project and set Texture Type to Sprite (2D and UI) so that it can be set as Source Image in our UI components. Then click...
