will you still be able to create studios in scratch 3

…

how many times has this kind of question been answered?

Scratch 3.0 is an update for the EDITOR and the website will not update drastically.

Hi all,
we want to run Scratch 3 on a standalone server pc for network availability problems.
We've cloned the Github repo, installed nodejs on the server and the clients connect and run the gui correctly, except for one problem: they can't see any resource in the catalogs (sprites, costumes, sounds, backgrounds).
Is there a way to load resources into the server so that the clients can see and use them?

Thanks in advance!

what risks would it pose? Please Respond

Its hard to collab since we cant really chat and its never real time. And whenever we save sometimes updates go through and some don't.

I don't think there is an automatic tool to do this for you, but you may want to take a look at the entries in src/lib/libraries. The ST has a private (I think) tool for generating this list from a project ID, but I've never heard of one to download every entry automagically. One option is to add a lot of sprites and costumes to one project, then download (either as an SB2 or SB3) and unzip it, then put all the image assets somewhere on your server. (I know the ST used this project at one point – be warned it'll take a little while to load in the 3.0 editor, though.

)

You would also have to modify src/lib/storage.js, which has the code for the actual downloading of assets. Particularly, you'll want to change the “addWebSource” lines – get rid of the ones for the Scratch site, and add some for the URLs on your standalone server.

It was showing an error around the closing tag.

Risks to what?

No significant changes will come to the site, other than making the style look more like the homepage. Scratch 3.0 is an update to the editor and player.

Oh, good! I grow more and more insane by the second seeing new navbar on the homepage and other “new” pages, but nowhere else. Looking forward to it!

I’ve been running some tests with Scratch 3.0 in iOS 11.4.1 on an iPhone 7 Plus. It does work, but there are a few steps you have to perform first.

This is what I got when I first opened the editor (in landscape mode):

I had to put it into portrait mode to continue, but I put it back into landscape mode after. This is what I got when I zoomed out:

See that empty space on the side? I can scroll the page using that blank space, and once I scrolled the (currently useless) navbar out of view, I got this:

So it’s very usable. The HTML5 and WebGL work great on iOS, and I imagine they can only get better.

Nice! Thanks for the report!
It looks like it would be quite usable on a tablet.

Thanks for the hint _nix. I successfully opened the project, but it seems that I'm unable to save it on my PC (Windows 10, Chrome). Any advice?

UPDATE: ignore this. After several minutes I had clicked the menu I got the save file dialog

You might've had that problem, but i can't even start the project! Any advice?

If you mean that the project page stays empty, just wait. As for saving, loading the project takes several minutes.

Yeah!

I actually never realized that the resolution of the iPhone 7+ was so big.

Yeah, I don't think that project actually has any scripts. It's just a big bunch of costumes and sprites that don't do anything

Have the WebGL problems for Raspberry Pi been resolved?
I still can't run it.

My browser / operating system: Linux (Raspbian 9.3 "Stretch"), Chrome (actually Chromium) 60.0.3112.89, Flash 29.0 (release 0)

Do I need an update?

I suppose this is wanted. the project has been created just to allow people to have a project will all the Scratch sprites.

UPDATE: I noticed now that this has been already answered by _nix
