Scratch 2.0 and Raspberry Pi (and linux in general)
If you've ever used linux you might have noticed how difficult it it to install flash(especially on ARM). And even if you do it tends to be very slow and unreliable in my experience meaning it doesn't work on RasPi well (if it loads at all). To me this seems a bit of a shame beacause a lot of RasPi users use scratch on their Pi and the BYOB, along with other new features is very useful.
My solution. Since it doesn't seem the scratch team have started on the offline version, mabye us, the AT community could begin to code this ourselves modelling it on Scratch 2.0 Flash. C++ seems to be the best language to use for this because we can easily compile it for ARM and it should be nice and quick.
Does anyone like this idea? have any suggestions?

Re: Scratch 2.0 and Raspberry Pi (and linux in general)
We could port gnash to play only 2.0, as opposed to swfs in general.
(wait nvm, gnash is slower than flash apparently)

C++ could be used 100s of times faster than the flash version.

Re: Scratch 2.0 and Raspberry Pi (and linux in general)
That's a good point. Perhaps we could write a framework simulating all of ActionScript using AS3's function names, then write a compiler that would modify the syntax to use our "language" (along with a good amount of macros)

0.o
That would be harder than writing Scratch in C++...

i guess we could, but if we do we are essentially rewriting flash (which adobe has stopped supporting).
and as MathWhizz says it would be harder than just rewriting scratch.

Yes, but it's not limited to 2.0. It would apply to any AS3 app.

Uh, no? That's only for mobile devices.

yes, but adobe have never been good at having a flash implementation for linux(let alone strange architectures like ARM) and flash on a 700Mhz 128Mb chip doesn't sound too quick...

Flash player keeps flickering a lot on Linux. Especially on Everybody Edits.

Uh, no? also for linux, except for chrome (which is also stuck behind at 11.2)

Re: Scratch 2.0 and Raspberry Pi (and linux in general)
just seen http://www.raspberrypi.org/phpBB3/viewt … mp;t=12522 on the RasPi forums... it seems the Pi can't even handle 1.x that well either.

Re: Scratch 2.0 and Raspberry Pi (and linux in general)
I hope you guys get Scratch to work on ARM because I'm dying to get it installed on my Android tablet with ARM Ubuntu on it 
I don't know why you say goodbye, I say hello!

Re: Scratch 2.0 and Raspberry Pi (and linux in general)
Hi All!
Of course you are welcome to make your own mod of Scratch - we love to see remixes! But please don't call it Scratch or use the cat or gobo. We want to avoid confusion, especially for new users.
As for offline - probably we'll end up using something like air, so the application looks / works the same online as it does off. It's *really* hard to get consistent performance and behavior with implementations written in different languages, so that's why we wouldn't try to make it in C or anything. But you are welcome to use the ideas from Scratch to make your own app!
Help Scratchers make the leap to 2.0!

cool, thanks! would scratch++ be ok?
also, if you didn't know Adobe has stopped supporting AIR on Linux

Re: Scratch 2.0 and Raspberry Pi (and linux in general)
Scratch++ is too similar, in my opinion. Why would you use pascal for coding?
Wouldn't it be better to add the features of 2.0 to the 1.4 squeak version?

Re: Scratch 2.0 and Raspberry Pi (and linux in general)
So has anyone made a version of Scratch for ARM linux yet?
