If you are an enthusiastic gamer who is ready to seriously get into game development, this book will give you a great head start for your journey. We will guide you through the step-by-step process of creating your first playable game prototype, which you will be able to further extend into a full-scale game. This book contains examples of the most important features that can be found in games, and much more; it will help you to understand Unity better, and increase your programming skills.

Unity is a powerful tool for anyone who aspires to build interesting and sellable games. One of the exciting aspects of Unity is how easily it can be extended to build custom characters and game environments. Scripting is the key to accomplish all this, but it comes with a steep learning curve.

This book will teach you everything you need to know about scripting in Unity. It will take you through creating, including and tweaking scripts for achieving various tasks. Some of these tasks include controlling characters, animations, controlling objects, handling game data and enemy AI.

The book will begin by building scripts for simple tasks and continue to develop them for increasing level of difficulty. The first few chapters include scripting to build a custom game environment and creating characters and controlling them. Arranging camera views, controlling and creating animations are covered in the next set of chapters.

The book then moves on to build objects, animate them and code character interaction with them and create inventories where the characters can pick ammo, health and other such objects. Towards the end, the book teaches how to add background sound and discusses basic enemy AI scripting.

What will you learn from this book

• Use available scripts that readers can use to create default character controller
• Attach default character controller scripts to an existing game object
• Set-up your own camera and character controller rigs through code
• Code dynamic and static objects like bio gun, ammo, health, character stat augmentation, treasure chests and make your character interact with them
• Create character item slots along with inventories, where players will be able to drag and drop different item icons in the inventory slots
• Attach existing animation scripts to characters and objects and create new ones
• Assign and equip selected items on a player or object, making them active and useable like adding fire functionality to a bio gun
• Create and maintain scores to control character objectives and save game data
• Setup a system to control transition between scenes and transferring objects from one scene to another along with instantiation for characters
• Deal with 2D and 3D parallax backgrounds
• Create an audio game controller to fix sound overlapping and create background audio stems
• Basics of enemy AI, such as path-finding and creating distinct enemy behavior and their awareness

Approach

The book is written in an easy to understand step-by-step style. It covers real-world examples for every topic, so that you gain most out of the book and are able to apply these techniques straight into your game.
