Leopard: Edit Scratch projects as JavaScript code

So wait(1); in leopard is setTimeout(myFunction, 1000); in Javascript?

Not necessarily since JavaScript's setTimeout is different from Scratch's wait _ seconds block. I believe with a wait time of zero, setTimeout waits ~4 ms while Scratch waits one frame, or ~1/30 seconds (~33 ms). Using native setTimeout might also be slightly unreliable when running other scripts at the same time. Also, using callbacks are a bit difficult to use inside loops; in a JavaScript async function, you might instead typically do “await new Promise(resolve => setTimeout(resolve, 1000))” (or write a helper function for this)

Use turbowarp packager by garbomuffin. It is better

you don't learn how javascript works from turbowarp packager

can someone tell me what this

{“error”:"This endpoint requires the params `files` or `parameters` in order to work. See https://codesandbox.io/docs/importing#create-wizard for more details.“}

means? after clicking on ”edit as javascript" I got redirected to https://codesandbox.io/api/v1/sandboxes/define where the message above appeared.
I was trying to convert this project https://scratch.mit.edu/projects/454347522/ if that helps anything.

As far as I can tell, that error appears when a project contains weird sprite or costume names. For example, your sprite “compressed file” has some strange symbols in its costume names.

Leopard should handle this gracefully, but it currently doesn't. If you want to make the translation work, you'll have to change those names.

Or you can use scratch packager. Also made by garbomufffin. But turbowrap packeger is better. I still prefer leopard though

Fun fact: garbomuffin made turbowarp

They're all real JavaScript, but some require Leopard's library.
This is correct. Leopard provides some built-in functions, which are a bit like “My Blocks” in Scratch. Essentially, we use regular JavaScript code to create some additional functionality for you, and then your project can use that.

So it's all real JavaScript code, but Leopard is doing a lot of the hard work for you.

What’s leopards library plug-in js?

how do I convert a project from my computer in leopard.js?

i guess you can upload it to an unshared project and link that

about that… my project exceeds the scratch size limit, so I can't.

There was an error converting your project.
Cannot read property ‘author’ of 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!

My project does not use pen nor any scratch extensions, but it's saying this error

Would be cool if people could learn js

Most ATers know JS, it's a simple programming language

That's just plain wrong. Even Scratch wouldn't be described as easy if/when you're trying to do extremely complex or performant things with it. When you've picked up one computer language, picking up more becomes easier but it still depends on how deep into the language you want to go and/or what you want to use the language for. Using JS for simple things is relatively easy. Using it for complex things isn't.

Good I think this is a awesome way for Scratcher's to improve in programing and learn other programing languages like java-script

I Love that!! Great!!

shonsh

great job

That would be nice,
If it will be possible to access variables, messages, … from outside the project.
(Assuming you know the names)

I will try it lol
