Also, the block uses jQuery to fetch the data, but jQuery isn't included with his extension

Ooops, completely forgot about jQuery when I made the 3.0 extension, I had written it to work through a chrome addon, and loaded jQuery through that. (it was originally an extension that loaded blocks directly into vanilla scratch)

I hope my post helped you in some way! Post count: 500+

thanks for your kind attention, your posts were really useful to understand I have to face with another route to try to do what I want! (I have to try to modify scratch-vm very little just to save locally some execution data, but I still don't know how to do this)

Try to code this:When red button pressed
If do not know, then

when green flag clicked
forever
reset timer
end
when [ timer] > (0.01)
next backdrop

that is unrelated

Hello,
after I create my own extension, is there a way to automatically load it's blocks just after launching Scratch? So as to skip clicking the lower left blue button and select the extension)? I'm using Github Pages to host the extension.

Yes, I did it in this way:

i do not know what the text editor is

two questions:
1.what file do you store the code on?
2. what language do you code the block?

I think there should be a speech to text extension.

recognize speech and wait for <> :: sensing
(recognized speech)
if <(recognized speech) = [type your words here]> then

Hello,

How can I load an extension in scratch-gui by launching

my_web_site/scratch-gui/?url=https://…

For example,

https://sheeptester.github.io/scratch-gui/?url=https://nitrocipher.github.io/ext2to3/ext-test.js

website loads the dynamic extension from another web page.

But when I build scratch-gui and run it, and give my url as a parameter,
it does not load the extension from the webpage.

this does not change also when I run the both the extension site and scratch-gui under https or http

do I need to run scratch-gui with some different parameter in order to load extensions from URL by giving it as a parameter?

Best Regards,

Sheep_maker

That is a modified version of Scratch made to load extensions from a URL.

Here are the changes that were made to make that possible:

Thank you very much. I've found your repository after I wrote the message.

I was able to compile your gui code and successfully integrated into my site with extension loading feature.

Best Regards,

i was wondering what is the: get info from www.google.com block because it doesn't seem to do anything

I have managed to port one of my extension to Scratch 3 (the blocks don't completely work yet, but I'm working on that, but they do load)

I followed the instructions to download the latest version of the scratch gui to work on it. I then copied the example extension, and rewrote my notifications extension in that format. Then, I uploaded it to github. I found the file that controls the list of extensions in the extensions button, and added mine. I set the URL to my github file, and it loaded in, and as you can see, the blocks appeared.

Official instructions for developing Scratch 3 extensions will be coming sometime between now and August (Scratch 3 release), according to The FAQ.

Update: I have everything working, except asking for notification permission. For some reason, that doesn't work.
Code can be found at https://github.com/JGames101/scratch-extensions/blob/master/notifications/3.js

To test your extension, add it to the index.js file located here: https://github.com/LLK/scratch-gui/tree/develop/src/lib/libraries/extensions
You can use actual URLs.
Then, if you open the page, you should see an extra Extension under the extensions popup thing. Clicking it will add your extension to the project, and you can test it.

So… testing your extensions currently requires downloading the source for scratch 3's GUI. No parts, like the VM or Renderer, are needed to be changed to test extensions, despite where default scratch extensions are stored (I went through the process of forking the VM for nothing…)

I will be making some simple demo extensions, that you'll be able to see below, and then I'll publish a fork of Scratch-GUI with some sample extensions.

do you know if you can make a project with all of those blocks?
