Hello

I would like to add a piece of JavaScript code to a sprite.
Heard about extensions but did not find anything that let me add this kind of code to a project.
or maybe I should do this another way..
Please put me on track.. thnks

AFAIK you will need to make an extension to do this. Read the official extension docs for info about this.

Try something like
(function(ext) {
    ext._shutdown = function() {};
    ext._getStatus = function() {
        return {status: 2, msg: 'Swag'};
    };
    ext.run_code= function() {
        // insert code here
    };
    var descriptor = {
        blocks: [
            [' ', 'Run Custom JavaScript Code', 'run_code'],
        ]
    };
    ScratchExtensions.register('JavaScript Code Runner', descriptor, ext);
})({});
Then use
Run Custom JavaScript Code::extension

Then use
Run Custom JavaScript Code::extension
keep in mind you wouldn't be able to share.

You don't. Make your extension be a userscript so it adds itself automatically, and it should work (note that sharing projects with extensions is probably not allowed, but you can put them on your own site if you want!)

@djdolphin and I asked to be in the developer group months ago, and while part of the ST acknowledged and forwarded our requests, the ST members who should have put us in the group haven't responded yet.

Now I am confused
Extension cannot be added, except for some Lego and what it was other if I am not a Dev
But a userscript can be somehow. But userscript is browser dependent. or what is this userscript? where is it stored?
Or does the Scratch add the userscripts that I make in a browser extension as an extension automaticly?

What comes to dev I am not that interested to have status like that in itself. But as I said in first place I want to add javascript to the program.
That it cannot be shared is not a big deal if it can be compiled to something that can be shared. Which I believe it can be. But belief is nothing testing is.

Userscripts are browser dependent, yes. It's basically a hack for automatically adding your extensions when you're not in the dev group. You need a userscript manager (browser add-on) such as Greasemonkey (FF), or Tampermonkey (Chrome, Opera), and then you'll need a javascript file ending in .user.js
Then you write code like this
// ==UserScript==
// @name		My amazing scratch extention
// @author		You
// @description	Your custom userscript
// @include		http://scratch.mit.edu/projects/*
// @version		0.0.1
// @grant		unsafeWindow
// ==/UserScript==
setTimeout(function(){
    (function(ext) {
        ext._shutdown = function() {};
        ext._getStatus = function() {
            return {status: 2, msg: 'Swag'};
        };
        ext.run_code= function() {
            // insert code here
        };
        var descriptor = {
            blocks: [
                [' ', 'Run Custom JavaScript Code', 'run_code'],
            ]
        };
        // unsafeWindow is important here!
        // it references the window of the actual page,
        // rather than the window of the sandbox this script runs in
        unsafeWindow.ScratchExtensions.register('JavaScript Code Runner', descriptor, ext);
    })({});
}, 10000); // set timeout to wait for flash to load
Name it myawesomescript.user.js and finally drag the file onto your browser to have it installed by your userscript manager

Thank you for clarifying.
I will try but this is only for evaluating or own fun.

at the moment it looks like I have to compile the scratch file to something else and add some code there.
But the compilers to be found are noy exatly to be found in abundace nor easy to use

Hello,

I installed Greasemonkey plugin in Firefox and added the userscript (myawesomescript.user.js) as you have already suggested but the Run Custom JavaScript Code Block doesn't appear in the More Blocks section. MegaApuTurkUltra do you have any ideas what is wrong?

Thanks in advance for the help

You're necroposting, I see this a lot from new scratchers on their first forum posts hehe..

I'd suggest using Google Chrome as it seems to work better on there (I can't get extensions running myself on FF).

There was a missing s in the includes
// @include https: //scratch.mit.edu/projects/*

Now it works in Chrome
