Unity Game Development Essentials

Overview of this book

Game engines are central to the video games we know and love. From the artwork to the mathematics that underpin the frames onscreen, the engine calls the shots. Aside from offering one of the leading 3D game engines, Unity also provides a superlative development tool ñ a tool that can produce professional standard games for Mac, PC, and the Unity Web Player. This book is a complete exercise in game development covering environments, physics, sound, particles, and much more, to get you up and working with Unity quickly. 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. From creating 3D worlds to scripting and creating simple game elements you will learn everything you'll need to get started with game development for the PC, Mac, and Web. 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. 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!

Opening the outpost


In this section, we will look at the two differing approaches for triggering the animation giving you an overview of the two techniques that will both become useful in many other game development situations. In the first approach, we'll use collision — detection a crucial concept to get to grips with as you begin to work on games in Unity. In the second approach, we'll implement a simple ray cast forward from the player.

Approach 1—Collision detection

To begin writing the script that will trigger the door-opening animation and thereby grant access to the outpost, we need to consider which object to write a script for.

In game development, it is often more efficient to write a single script for an object that will interact with many other objects, rather than writing many individual scripts that check for a single object. With this in mind, when writing scripts for a game such as this, we will write a script to be applied to the player character in order to check for...
