Sir,
I have created js file extension for scratch 2.0. But, I can't able to import .js file in Scratch 2 offline editor. I kindly request you to send me how to import .js file in Scratch 2 offline.
Regards,
Robotics

Open up the browser console while in the editor and paste in the extension code to load the extension.

hi!

The extension name should be an alphanumeric string in CamelCase, e.g., SensorBoard.

That's not camel case. Camel case starts with a lower letter, you were using Pascal Case.

You can't.

The offline editor doesn't support js extensions

$(".box-head")[0].textContent = "committing AT crimes since $whenever"

I'm afraid as MegaApuTurkUltra said the offline editor doesn't support js extensions. Why exactly do you need to use extensions in the offline editor as opposed to the online editor?

Offline extensions allow you to write extensions in whatever programming language you prefer, rather than being forced to use JS.

@technoboy10 That is “sort of true”. If you use websockets, you can also use any language you wish if you want to run a “server” instead of everything being contained in the browser. Since the JS extensions do not support Linux, there is no other way currently to do this for Linux. It also means you can address any device you like via IP address. See xi for an example.

Ah, that's true. I forgot about websockets!

@comp09
websocketd.com looks cool. Here is something you should checkout: http://crossbar.io/. I am hoping to make this the basis for my next Scratch extension.

Hi there.

I'm a newbie to Scratsch and WeDo but a Pro into LEGO building.

Wonder if you can help me with my LEGO Wedo hub problem?

I would like to connect this Touch sensor http://alpha.bricklink.com/pages/clone/catalogitem.page?P=879#T=C
from LEGO to the hub,via this extension cable from LEGO. http://alpha.bricklink.com/pages/clone/catalogitem.page?P=60656#T=C

But how on earth do I get Scratsch to read the touch sensor wenn it is pushed?

Can anyone please help me?

Yes, if you'd like to make a Scratch 3 extension see here.
