Before Pong we had to do a nursery rhyme. With animation, not simply a storyboard with text. In Snap, the main way to animate is to change the sprite’s costume. There are two costume-switching blocks. These are in the Looks section. One is which changes to the next costume in the set of costumes loaded for that particular sprite. The other iswhich allows the coder to choose which of the loaded costumes to switch to at that point in the code.
Animation also often involves movement from one position on the screen to another and there are two blocks for that, too. (well, several actually, but two that are useful in animation). These are found in the Motion section and are and Both of these take numbers or variables as parameters in the little ovals that I left blank.
There was a rubric for the nursery rhyme. Students can earn up to 20 points for their project. Here is a screenshot of my nursery rhyme.You can see it here. Assets are from clker.com except the background (included with Snap) and the waterspout (created in GIMP). The text sprite was also done in GIMP. Most assets were modded in some way—either to make a second costume or (in the case of the sun) to make the text sprite more readable.
Apparently, Unit 3 is a “platform game” and I don’t even like those (except maybe Cosmo’s Cosmic Adventure). Watch this space for more exciting Snap stuff as I figure out what kind of platform game I’m going to create and how it will work.
