I dont see any buttons next to it. 

The "blue" check mark button is not blue in the most recent version of Snap!

The checkmark on the right, adjacent to the input field and inside the blue border is a button. You can click on it or simply enter text in the field and then hit the enter key on your keyboard.

I'm not exactly sure. I thought (quote (1 2 3 (4 5) ) ) was like an abbreviation of (list (1 2 3 (list 4 5) ), where (quote +) became a new data type "symbol" '+.

I guess it's true that if your atomic data are only numbers, which are self-evaluating, then you can always use LIST to assemble lists instead of quoting them.  But I wouldn't say that QUOTE abbreviates LIST; in fact QUOTE is simpler, taking whatever value it's given as argument and returning that value without further evaluation.  But it only really matters once you introduce symbols.

PS You have an extra open paren, in "list (1 2 3" above.

My bad. I was trying to avoid the two-brackets-green-crescent thing (why don't they disable that already?!). I found out (with a quick Wiki search) you do it by selecting "never show smilies as icons for this post" under "options", but then you can use actual smilies. Oh well.

"if on edge bounce" is probably the most controversial primitive in all of Scratch. You don't have to use it (in Snap it also is still buggy and doesn't behave right), instead you can check using the TOUCHING ? predicate from the sensors category, whether a sprite is touching the edge of the stage, and disambiguify which one it is touching using the sprite's coordinates yourself.

Snap! dev update

Check out presentation mode (called "app mode" in Snap) and small-stage-mode in the new Snap! alpha

Enjoy!

Eh? Snap in Chrome on Mac Lion is about 10x faster than BYOB 3 or Scratch 1.4 for me!

It's not just the running of the code, the dragging of blocks, and trying to type numbers and letters has about a 1-10 second delay.

Hi tjbrady,

I had to take project summaries out of BYOB. But in the new version (Snap!) the projects themselves are stored in a readable XML format. Some instructors have already been examining these XML files for analyses and found them to be useful. we'd be very insterested if the new project format helps you.

Thanks!

the project version attribute refers to the project format version, so we can stay backwards compatible if - at some future time - we need to restructure the XML tree.

But, to answer your question, yes, we'll be adding more attributes to the project format, and there will be a way to track remixes etc., because we'll also be working on a Snap website with cloud storage etc.

Stay tuned!

while playing in BYOB3, i noticed that the distance to dropdown doesn't show the sprite which you program in, making it difficult to use it as a lambda and execute in another sprite ((distance to sprite1)) of (sprite2)). fix it?

(also in touching, point towards, go to)

Ooh... sounds like fun!

Question: In BYOB 3.0, when you do ((the script {code}) of [sprite 2 v]) in sprite 1, if code refers to (object [myself v]), does that mean sprite 1 or sprite 2?
