Unity 3.x Game Development Essentials

By: Will Goldstone

Overview of this book

Game Engines such as Unity are the power-tools behind the games we know and love. Unity is one of the most widely-used and best loved packages for game development and is used by everyone, from hobbyists to large studios, to create games and interactive experiences for the web, desktop, mobile, and console. With Unity’s intuitive, easy to learn toolset and this book – it’s never been easier to become a game developer. Taking a practical approach, this book will introduce you to the concepts of developing 3D games, before getting to grips with development in Unity itself – prototyping a simple scenario, and then creating a larger game. From creating 3D worlds to scripting and creating game mechanics you will learn everything you’ll need to get started with game development. This book is designed to cover a set of easy-to-follow examples, which culminate in the production of a First Person 3D game, complete with an interactive island environment. All of the concepts taught in this book are applicable to other types of game, however, by introducing common concepts of game and 3D production, you'll explore Unity to make a character interact with the game world, and build puzzles for the player to solve, in order to complete the game. At the end of the book, you will have a fully working 3D game and all the skills required to extend the game further, giving your end-user, the player, the best experience possible. Soon you will be creating your own 3D games with ease!

Understanding Translate


To actually use these variables to move an object, we will use the Translate command. When implementing any piece of scripting, you should make sure you know how to use it first.

Translate is a command which is part of the Transform class: http://unity3d.com/support/documentation/ScriptReference/Transform.html.

This is a class of information that stores the position, rotation, and scale properties of an object, and also functions that can be used to move and rotate the object.

The expected usage of Translate is as follows:

Transform.Translate(Vector3);

The use of Vector3 here means that Translate is expecting a piece of Vector3 data as it's the main argument—Vector3 data is simply information that contains a value for the X, Y, and Z coordinates; in this case coordinates to move the object by.

Implementing Translate

Now let's implement the Translate command by taking the h and v input values that we have established, placing them into Vector3 within the command.

C# and...
