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.

Keyboard input to a program


There are many cases where you may want to get your user to input some text or numbers into a program you are creating. For instance, you may want to get your program to get a value to change something from the user. You may also be playing a game and need input from the user to answer a question.

In this recipe, we'll explore how we can use a Sensing block that will accomplish all of this for us.

Getting ready

To prepare, let's create a new program. We'll create a program that creates a bit of user interaction and incorporates some of what we've learned already. Import a sprite of your choice, as well as a background of your choice, before we get going.

Note

We are using Tera (from Fantasy) as our sprite with bedroom2 (from Indoors) as our background. The rest of this section of the recipe is preparing for a couple of the optional things we'll do in this recipe.
