September Valentine

Hearts, particularly valentine hearts, tend to be a feature of February rather than September. Fortunately, my valentine isn’t crammed full of them. I’ll share it with you, below, as it’s a Snap project.  This school year, I’m providing what TEALS refers to as “lab support” for students in the morning class at DeKalb High School of Technology—South (DHSTS) in Decatur, Georgia.  And, as part of that, I’m working the projects, same as last year, although now, Snap, is not a stranger to me.

DHSTS is a magnet school.  Students are bused in from other high schools to spend half a school day (four periods) in my class, five days a week. This means we cover a lot of material in a short time. In fact, they’re doing an intro to tech first quarter,‘s Computer Science Principles during the second quarter and AP Computer Science (with Java and a test), third and fourth quarters.

Which brings me back to the valentine.  As part of the intro, we’re doing a little Snap and we’ve chosen what TEALS calls the Animated Storytelling Project.  Last year, I did a nursery rhyme, “Itsy Bitsy Spider” and all of my students did nursery rhymes as well. This year, it’s expanded. It does have to (loosely) tell a story/narrative and fulfill the rubric.

And so, I present to you.  Carol Ann Duffy’s poem “Valentine” in Snap.

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 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.
