In Detail
Scratch 2.0 is an easy to use programming language that allows you to animate stories and create interactive games. Scratch also gives you the capability of using programming to calculate complicated calculations for you.
Scratch Cookbook will lead you through easy-to-follow recipes that give you everything you need to become a more advanced programmer.
Scratch Cookbook will take you through the essential features of Scratch. You'll then work through simple recipes to gain an understanding of the more advanced features of Scratch.
You will learn how to create animations using Scratch. Sensory board integration (getting input from the outside environment) will also be covered, along with using Scratch to solve complicated and tedious calculations for you. You'll also learn how to work through the exciting process of project remixing where you build on the work of others.
Scratch Cookbook will give you everything you need to get started with building your own programs in Scratch that involve sounds, animations, and user interaction.
Approach
A practical approach with hands-on recipes to learn more about Scratch and its features.
Who this book is for
Scratch Cookbook is great for people who are still relatively new to programming but wish to learn more. It assumes you know the basics of computer operation. The methods of using Scratch are worked through quickly with a focus on more advanced topics, though readers can move at their own pace to learn all the techniques they need.
