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!

The player is the best object upon which to store this information, as it will allow other objects to query this Inventory script for information—for example, later we will add a 3D model of a generator, which will display the current charge state of the door based upon information in this script.

Select the Scripts folder in the Project panel and click the Create button, then choose the relevant scripting language you have been working in. Rename your new script Inventory, and launch it in the script editor.

Saving the charge value

As we are establishing an inventory of collected items, we should make particular values of the inventory available to all scripts. The amount of power cells collected...
