Have you noticed that Gentoo and the Yeti face forward rather than left or right? That helps you
because, as you saw in the Hungry Spider app, if you want sprites that can face left and right, you
have to produce two sets of images and write blocks of code that can switch between them depending
on which direction the sprite is travelling. Having the characters face the player means you cut down
on a lot of coding! If you’re familiar with MIT’s Scratch programming interface
(http://scratch.mit.edu/), you know there are sprite controls to do this hard work automatically—
hopefully we’ll see something similar in App Inventor very soon.
