I'd love it if anyone could give a good head to head on Scratch 2.0 vs. Snap! 4.0[1] (the new name for BYOB, Berkley's Scratch spin-off). I realize that Snap is aimed more teaching high school/college CS, but they're seeming to converge a bit. I don't have a CS class this year, so I haven't set aside enough time to dig into the latest versions of Snap or Scratch. If anyone has any insight to share, it'd be greatly ap…

Since Snap doesn't rely on Flash, it nominally works on an iPad.

2.0 may have been a long time in the making, but I just bought the Scratch Adventure book for my kids last week, which uses 1.4, unaware of the pending update. When I went to the site to download Scratch, it was down while preparing for the 2.0 release. I thought it was a pretty ironic introduction to programming, always new shiny objects.

Anyone know more about how the social features are moderated? Thats my first thought these days, sad I know but...

I don't know how they do it. I have seen some pretty freaky games on their webpage, and I have seen a lot of games uploaded from game-programming events that I have hosted.

My son is finally make his space shooter the way he envisioned because of the new clone sprite action. Exciting times ahead, here is a pic of him getting down last night: https://pbs.twimg.com/media/BJ3OudQCQAALZCc.jpg:large

He already has the programmer lean. I see many good things in his future.

I had to implement some unsatisfying hacks to make my Scratch shooter work as well! If I remember correctly I was manually duplicating the master projectile and I had to register each projectile against each enemy.

It does, kind of, didn't try it our extensively but I got things to happen.

One important thing that's new in Scratch 2.0 under the hood is the transition from the .SB file format (a rather complex SmallTalk object store) to a ZIP based bundle containing all required media along with JSON encoded scripts. The upshot of this is that consuming Scratch files in other apps should be a lot easier. That said, one downside of Scratch 2.0 (at least in my view) is the migration to a Flash based edito…

Actually, there is at least one web-standards-based playback engine - http://wiki.scratch.mit.edu/wiki/Sb2.js

Although the content-creation tool sadly remains in Flash.

Im not sure if clone works as expected though. He has a laser beam and it listens for a 'shoot' broadcast. When it hears it, a clone of 'myself' is made, it is placed behind the ship, and a loop moves it to the left. However, if 'shoot' is broadcasted multiple times, new clones are not made and the same laser beam is placed behind the ship. Maybe we'll put the clone logic on the broadcast portion and not on the laser itself. Programming is fun, I can't wait to nudge him to try that approach
