I'll start testing it out for #ScratchGPIO compatibility and working over VNC

Hello,

I looked for a nice feature in scratch: animated gifs. It Works in win-1.4 and legacy-1.4: import costume, it will load each frame as a separate costume then.
Unfortunately, it does not work with nuscratch5-1.4: the import first runs on a breakpoint (ok, it is beta) and then after selecting the file it simply does nothing.

See a working sample in http://wiki.scratch.mit.edu/w/images/Popular_GIF.gif
Instructions in http://wiki.scratch.mit.edu/wiki/Animated_GIF

Regards,
Gerhard

Hah! Oddly enough I just dealt with that a couple of weeks ago; it's in the upcoming beta release. Which is being kept back while we try to get a handle on the sound lock-up problem. Which looks like a possible kernel fix is needed, since apparently there is some clash between the timer interrupt I'm using and some other important vector that ... whatever.

Just tested NuScratch5 for compatibility wit ScratchGPIO and it seems fine - sends out broadcasts and variable changes and receives sensor updates from Python :)

Simon
PS Any reason for font change from standard 1.4? Obviously makes it easy to see what version is being used but on the other hand it makes it look strange/different and that might not be best idea for young scratchers moving between PC/Mac/Pi

Excellent. Thanks for testing it out.

Yup. The deeply technical and important one of "I didn't get around to doing anything about it." I've done something about it for the beta release. Which should be out soon... if the sound nonsense can be solved.

... and the beta release is now official. I had to fiddle with the VM a bit to avoid using a timer interrupt that ALSA also uses and uses incorrectly. Fortunately the current Raspbian kernel allows thread priority munging and so the alternative timer handling regime was practical. The upshot is that sound no longer seems to cause any lockups, which is nice.

We should consider this forum thread locked though and move to a new one for the Beta release(s).

I am new to Scratch & Squeak, but listening to Tim at http://smalltalkinspect.podspot.de/post ... -rowledge/ I would assume that the software is faster under RISC OS than Raspbian as the RISC OS Wimp is much faster than X-Windows. Are these new versions available for RISC OS

is NuScratch now 'standard' on Raspian .img ?? Or do you have to use the prescribed installer on this page to get it ??

Hello,

nuscratch is standard since raspbian 2014-12-24, the xmas-release. There have been some hickups with this distribution, but with current raspbian these are corrected, especially the startup script.

'old' scratch is still available, start it with sratch.old from a terminal window.

nuscratch is starting with title line 'scratch 1.4 of 14-Jan-15'.

Regards,
Gerhard

So how do you folks feel about running Asteroids fast enough that it gets throttled to 'only' 50 fps?

Coming soon...

oh, and without throttling it now does around 200fps on a pi2.

Hello,
do you already have plans when this release is delivered to the public ?
And what is progress on bug fixes ? Kids in school complained a lot about the "sudden crashes".

Gerhard

Pretty soon; and I'll be back at the bug-fixing mines very soon. Some stuff to do with AstroPi etc first.
