So there IS a way to mod 2.0!

It's not modding, it's just extensions. Like plugins.

I made a node.js framework for Scratch extensions. You can check it out on Github.

I followed the step-by-step HelloWorl tutorial. I got the “say hello” block. When I click it I don't see “Connected to Scratch as ”HelloWorld“, port 12345 Hello, world!” in the node.js command prompt (I'm using Windows 7). Is there where I'm supposed to see the extension output?
You should see “Connected to Scratch…” in command prompt as soon as you import the extension into Scratch. Do you see any output when you run node extension.js?
For me it never says connected to scratch but it still works, apart from reporters.

Same… I still have no idea why it does that. Also I like the AttackScratch.php link in your sig.

AAARGH!!! Reporter blocks don't work. Please fix this.
Thanks.

Should be fixed. Sorry, for some reason I couldn't reproduce this one until recently.

Cool! I'll try it when I get home (watch my siggy)

Just FYI: After seeing @technoboy10's demonstrations today, johnm hinted that he might try replacing Scratch 2.0's experimental extension system with something more like Snap!'s HTTP-based plugin system.

Oh, interesting. @johnm: what benefits do you see in switching to HTTP? I like the socket-based protocol because it allows two-way communication; e.g., it could allow custom event hat blocks, blocks that halt execution until they finish running, and reporters which perform a calculation rather than return a polled value (without long-running HTTP requests for the latter two).

I don't want to misquote him – he can answer himself! – but I think just because it's so simple.

WebSockets are faster than HTTP, and Sockets are faster than WebSockets…
For web apps WebSockets are the easiest…

Oh and nXIII is there a javascript API in the actual page (ASLoadProject?)

EDIT: Nvm I found it!

EDIT: It would be nice to have documentation though

What data is sent to and from the node.js program?

*sigh* BBB…

So how does your node.js thing work? I want to use extensions without needing to cope with JavaScript. How do you get the blocks to work without hacking the website and modifying the scratch.swf?

I've been playing around with this for far longer than I care to admit (I could be doing so much more useful stuff, like going outside…) and this is obviously very touchy - but I finally placed all my missing commas and such and this is working more than beautifully for me. A few things I'd like to do rely on an existing variable. Is there a place that I can define it (and do anything else I want on initialization) where it can be accessed in extension.js? I've stuck it most of the places I could think of and it hasn't worked. I'd like to avoid defining it in every block definition or needing to create an block.
Thanks!

Can I have the name of the API?

A variable in Scratch, an extension reporter block, or a JS variable?
