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.

Changing the cursor at runtime


The cursor is another important UI element that is not directly controlled by UI classes. This is the case since they are new in Unity, while the cursor was already implemented earlier. However, changing the cursor at runtime could be very useful for the player to distinguish different actions, and it can also be graphically nicer. For instance, in a Real-Time Strategy (RTS) game, the cursor can change when the player decides to move units or orders them to attack enemies.

At this stage, you are also ready to learn other techniques to deal with UI events, directly inside your scripts, instead of setting them through the Inspector, maybe also using the Event Trigger component. In fact, here you will learn how to use event handlers to triggers events in your script.

In this example, we will see how to change the cursor when it enters or overlaps another UI element. This is the most common case of cursor changing, and you will come across different games that have...
