Implement glide #1062

Open halatmit opened 6 years ago

halatmit commented 6 years ago

Implement glide for sprites, similar to Scratch. This might done using Evan's idea for a blocks thread, but it might be simpler and better to just do the glide on a separate thread, similar to how sprites move under setSpeed.

Note that Scratch's Glide command is a blocking command, so we would do presumably do this using Evan's blocks thread.

Implementing a non-blocking guide was trivial but would probably confuse the user. Should we offer a non-blocking option or just make it always blocking? A pro argument is so someone can have multiple glides take place at the same time. A con argument is that it's confusing to have multiple options. Let me know what you think and if I should post to the list.

In either case, we have to figure out what to do with collisions while gliding.

@ewpatton could you please point me to your blocks thread or other relevant technology?

Just off the top of my head, I think glide should block. But I could be convinced otherwise.
