Scratch

I'm able to create projects online. Does this mean the offline version will be terminated?

I'm not sure if it is good the different color of shift-click menus on blocks of different categories. It could be visually nice, but, as I don't see any relevant information conveyed by the color of each menu, it could also be confusing. People are used to white menus, so, if the color is not meaningful, I think the new GUI should also stick to white menus.

One big concern as a teacher:  Will the ability to remix blocks of code still be recorded in the new projects so that you can tell when someone just copies code versus implementing it themselves?  Really like that students have to recreate code rather than just copying it if they don't want to indicate that the project is remixed.  Otherwise, it looks great, especially the ability to add Scratch blocks to posts.  WIll the comment size limit be increased to accommodate this addition?

It is nice to see when sprite variables are set "For this sprite only" that cloning creates instance variables. It would be a shame however to be required to clone a sprite with all of its overhead just to get instance variables for each recursion of a custom block. This would also causes a bottleneck because your sprite code could not directly access the instance parameters and your block code could not directly access the sprite variables. Being forced to resort to a list would be a huge let down. Is there anyway you could add instance variables to make your own block or is it already too late?

Edit: My mistake. The block code is part of the sprite code. Still seems a shame to clone just for variables.

BUG REPORT
When cloning, all the values for the clone should be taken from the same source. The prototype takes some from the master sprite and others from the calling sprite. I favor the later but ether is better than chaos.

No full screen in edit mode!!!!!! i need this to test my projects!

Theres a glitch where the up arrow key scrolls the page up when you mean to do it in the project.

Just click on the project and press the up arrow again.

The Scratch 2.0 Prototype is no longer open for public trial so I'll close this topic.  Thanks a lot for all your great feedback!  It is very helpful to the development team

1) What will the music file size be on Scratch 2? I'm worried that if everything is online than there will be no compressor and there won't be enough music space.

Haven't yet decided, but the limit will probably be somewhat higher than in Scratch 1.4. We may add compression in a future release.

2) An actual suggestion: Is there are a way you could speed up the creator? I did a test with Panther 1.0, and although it is a glitchy mod it can make just over 300 clones before it slows down. I did the same test with Scratch 2.0 on google chrome and found it could only make around 60 before it started to lag. I really want to make a city game with clones, as my last one failed without clones, but with a 60 clone limit before it lags I don't think it will be possible.

Clone creation is slower than it should be. I'm working on that.

How many clones you can create before things slow down depends on many factors, including your computer, the costume type (SVG costumes are currently slower than bitmap ones), costumes size, and what the clones do. If the clones don't do anything you can have more of them than if they do expensive operations such as graphic effects. You'll need to experiment to find good limits. There's also a built-in limit on the number of clones to prevent run-away projects from locking up Scratch. The limit for Scratch Day was 1000 clones, but it will be lower for the release version, probably around 300.
