Requirements:

• Text Editor (Text Edit, Notepad, etc.)
  
• Web Browser with a console (Safari, Chrome, etc.)
  

Making The Extension:
You can either follow the directions at this awesome site or follow the directions below for how to make the Javascript extension.

1. Open up your text editor and paste this code in the editor:

   (function(ext) {
       // Code to be run when the user closes the window, reloads the page, etc.    
       ext._shutdown = function() {};
       
       // Shows the status of the extension 0 = red, 1 = yellow, and 2 = green
       ext._getStatus = function() {
           return {status: 2, msg: 'Ready'};
       };
       // Descriptions of the blocks and menus the extension adds
       var descriptor = {
           blocks: [
           ]
       };
       // Register the extension
       ScratchExtensions.register('Hello World', descriptor, ext);
   })({});
   

2. Lets add the simplest block (a block that does nothing) to make this block add this code

    [' ', 'hello world'] 
   

   into the part of the code in the editor that says var descriptor = [ blocks: ]; in between the brackets to the right of blocks: if done correctly it will add this block:
   

   hello world :: extension

3. Lets install this now! open up your Web Browser and create a new scratch project then open up the Javascript console and paste the code in your text editor into it then press enter (if it doesn't auto load). If the More Blocks pane contains Hello World then hooray you've made your first extension!
   

Moving On
Go to this site for more on extensions.

Nice tutorial!

Although it is giving me an error.

Sorry ChocolatePi keep trying to make your extension. The extension that I made threw an error just because I accidentally typed an r in an incorrect place . If you keep on having errors it could be that my tutorial was wrong if so try this site. If you figure the error out please post your extension I'd love to try it out.

Good Luck Iwotastic!

Please don't necropost.
The last post was on April 1st and that was a necropost on a year-old topic.
In the future, please try and check the date.
The javascript console is normally in a area accessed by pressing F12
April 1st was 8 months ago. The general rule (on most other forums) is after a month of innactivity, the topic is dead.
Just wanted to warn you as it can annoy some people.

Great! I actually am making a scratch extension that has radian trig. I'm guessing that that is what your extension does.
