In this two-part article by Michael Badger, we will get comfortable working with Scratch by covering some basic concepts. Each Scratch project contains sprites with costumes, scripts, blocks, and a stage with backgrounds. In the first part, we built a couple of sample scripts to demonstrate how we can control the sprites in a project. For example, we used motion to move the sprites and forever loops to keep the sprite moving.
In this part of the article, we will use broadcast messages to coordinate the actions of multiple sprites. We will conclude this article by sampling and remixing projects from Scratch's sample projects and from the Scratch web site.Read Getting Started with Scratch 1.4 (Part 2) in full
