Yeah, this is a stretch... an example of how you might use the glide block. Not very useful, to be honest. I have used it myself only a few times, in animations. As illustrated in this example, you can have sprites/clones deviate from the glide trajectory, and then return them (as in the "message1" broadcast handler in this example). However, there's no easy way to stop individual sprites/clones, once you've set them gliding. Anyways, I thought this example looked fun, that's the real reason I shared it. All code by me (@kriblo).
