Preface

Scratch 2.0 (released May 9, 2013) is the second major version of Scratch to be released during the life of the product. Among other things, it features a redesigned editor andwebsite, and allows you to edit projects directly from your web browser.

This module (tutorial) is one in a collection of modules designed to help beginners of all ages (8 and up) learn how to create the code for computer programs using Scratch 2.0 . Information is provided not only for the beginners themselves but also for theirparents and teachers where appropriate.

The purpose of this module is to highlight a few Scratch projects.

Viewing tip

I recommend that you open another copy of this module in a separate browser window and use the following links to easily find and view the imageswhile you are reading about them.

Discussion and sample projects

Fireworks by cloning

One of the very interesting new features of Scratch 2.0 is cloning. You will find some instructions for using this feature at Clone Blocks . According to the material on that web page, the use of clone blocks:

Creates a clone of the specified sprite. (The clone is a duplicate that only lasts while the project is running.)

Image A shows a screen shot of a project named FireWorks by Illusionist .

This screen shot doesn't begin to do justice to this project. Click here to run the project online. Press the spacebar to fire a single rocket. Hold the spacebar down for agrand finale.

You may notice that I remixed this project. However, I made no changes to the original project by Illusionist . My purpose in remixing the project under my user name was simply to ensure thatthe project will continue to be available in its current form. In the past, some of the Scratch projects that I have referred to have later been removed from theScratch website resulting in broken links in my documents.

StarDoors01

Click here to run the project named StarDoors01 by dbal . A screen shot from the project is shown in Image B .

While the screen shot in Image B isn't all that impressive, the project illustrates several important Scratch programming concepts including frameanimation, scaling, communication among sprites, etc.

Perspective03

Click here to run the project named Perspective03 by dbal . A screen shot of the project is shown in Image C .

This project continues the theme of frame animation. In this case, however, there is also the illusion of perspective. The animated sprite follows the mouse andappears to move further away from the viewer as it approaches the horizon.
