Leopard: Edit Scratch projects as JavaScript code

godsparrow

why is this failing https://scratch.mit.edu/projects/1107128476/

POW_Boy1

For some reason I tried to convert this https://scratch.mit.edu/projects/1106616352 to java but it just, doesn't work. I tried all the options, The sandbox says I don't have any permission or it doesn't exist, another thing that it keeps on happening is this error thingy stating - "There was an error converting your project.

request to https://assets.scratch.mit.edu/internalapi/asset/2df77062fad7078aac7ba42fc7898db9.png/get/ failed, reason: connect EMFILE 151.101.42.133:443 - Local (undefined:undefined)

Leopard only supports new projects (created in Scratch 3.0). And the only supported extension is “pen”; all others will fail.

If you aren't sure why your project is failing, ask on the forums!"

please help me with this.

The website homepage is not blocked by my school but when I convert a project it gets blocked.

This project (https://scratch.mit.edu/projects/1120738178/) gives me this error (Cannot read properties of undefined (reading ‘value’)) when translating. unclear why its doing this so any help is good!

Is it possible to add a feature that converts JavaScript back into scratch code? This way we can copy-paste code from our Javascript and run it in scratch. This could also help people understand Javascript better when the scripts get broken down into scratch code, Sort of like how Code.org allows you to toggle blocks and written code.

The difference is that code.org actually attempts to have their code be compatible with JS- and vice versa. Scratch doesn't- and Scratch lacks many features of JS, like returning values, objects, the prototype chain (including classes), null, undefined, nested arrays, promises, regular expressions, multiple mathematical operators (and a decent chunk of the Math class), JSON parsing, and URL parsing. That's a non-exhaustive list, by the way.

With something like code.org, they have built-in ways to handle that, while in Scratch, much of that would have to be done using slow and large polyfills.

why is the limit less the the limit for scratch? can they update the website so the limit is the same so large projects can be converted?

set [ maxsize] to ([ maxsize] of [ scratch])

Issue: crashing
I try to load any project, like an sb3 file, but code sandbox crashes with 404. Any fixes?

This project runs really slowly so I am hoping that this helps it run faster. However, this project will not open and I am not sure why. Its trying to make a 4x4 square of letters where every row and column is a different word. My best guess is that the list is too long. Any ideas?

Never mind, I shortened the list and it worked

What does this mean: There was an error converting your project.
Cannot read properties of undefined (reading ‘name’)
Leopard only supports new projects (created in Scratch 3.0). And the only supported extension is “pen”; all others will fail.
