Overview of this book

If you are a Unity developer looking to explore the newest features of Unity 2021 and recipes for advanced challenges, then this fourth edition of Unity Cookbook is here to help you. With this cookbook, you’ll work through a wide variety of recipes that will help you use the essential features of the Unity game engine to their fullest potential. You familiarize yourself with shaders and Shader Graph before exploring animation features to enhance your skills in building games. As you progress, you will gain insights into Unity's latest editor, which will help you in laying out scenes, tweaking existing apps, and building custom tools for augmented reality and virtual reality (AR/VR) experiences. The book will also guide you through many Unity C# gameplay scripting techniques, teaching you how to communicate with database-driven websites and process XML and JSON data files. By the end of this Unity book, you will have gained a comprehensive understanding of Unity game development and built your development skills.

Saving screenshots and RenderTextures to files

At each point in time, a RenderTexture contains an image – a screenshot from the point of view of the Camera rendering to that RenderTexture. Games can have features such as snapshots at exciting points in time, such as crossing a finish line, landing a difficult jump, or taking the lead in a race. Through scripting we can take the picture data from the RenderTexture and save it as an image file.

Also, if you simply want to be able to take a snapshot of the Game screen (Main Camera view) at any point during the game as a PNG file, this is something Unity has made really easy too. We’ll explore both these features in this recipe.
