Learning C# by Developing Games with Unity 5.x - Second Edition

Overview of this book

Unity is a cross-platform game engine that is used to develop 2D and 3D video games. Unity 5 is the latest version, released in March 2015, and adds a real-time global illumination to the games, and its powerful new features help to improve a game’s efficiency. This book will get you started with programming behaviors in C# so you can create 2D games in Unity. You will begin by installing Unity and learning about its features, followed by creating a C# script. We will then deal with topics such as unity scripting for you to understand how codes work so you can create and use C# variables and methods. Moving forward, you will find out how to create, store, and retrieve data from collection of objects. You will also develop an understanding of loops and their use, and you’ll perform object-oriented programming. This will help you to turn your idea into a ready-to-code project and set up a Unity project for production. Finally, you will discover how to create the GameManager class to manage the game play loop, generate game levels, and develop a simple UI for the game. By the end of this book, you will have mastered the art of applying C# in Unity.

Hiding and showing the Canvas


We have decided that the UI in our game will be made up of three simple views:

  • MenuView

  • InGameView

  • GameOverView

We have created most of the MenuView. I am using two terms here, View and Canvas. In our simple game, both of them will mean the same thing. MenuCanvas is just the visible part of MenuView. Keep that in mind.

The simplest way to toggle the view's visibility is by enabling and disabling the Canvas component. Let's test how it works without the code for now:

  1. Press Play in Unity.

  2. Select the MenuCanvas game object in the Hierarchy window.

  3. Disable the Canvas element, marked here:

  4. As the Canvas component is responsible for rendering the UI in the scene, disabling it will hide the content of all UI elements within the canvas.

    Note

    Note once again that disabling the Canvas component will hide all UI elements within the canvas. It will also disable all events handled by the Event System.

It's been a while since we wrote some code. Let's implement the same behavior in the...
