Learn everything you need to know to use the powerful Unity engine to its full potential for 3D and 2D game development, simulation, artificial intelligence, and beyond. From the basics of scripting to techniques for interactivity, AI and behavior, animation, narrative, and networking, this flexible, mind-bogglingly popular engine is useful for anything that needs visuals and real-time simulation. With this thoroughly updated problem-solving cookbook, beginner and intermediate Unity developers will learn about the Unity engine through brief recipes that teach specific features of the software and scripting systems. You'll apply a collection of snippets of code to address common scenarios such as properly keeping score, accepting input, and sharing state over the network. In this book, we’ve assembled a selection of recipes to solve common problems that we’ve found ourselves solving over and over as we build using Unity. This book won’t cover every single tiny thing you want to know about Unity, but it hopefully covers the majority of things you’d be doing day-to-day in video game development.
