Hello, this is a tutorial to start explain how to use speed variables to move a ball. I intend to build this up to the 3D bouncing ball, but judging from comments and other Scratch sites, I ought to start here. About the photos used: the speaker is among the people in the Scratch package, and there were lots of images, so thank you Cassy, wherever you are :-) The ball also comes from the samples, added the eyes at the request of my wife (also Cassie). Enjoy, and keep scratching!
