All right that is my simple talking engine But wait why is it not working It's because data cannot confirm That it is in the positive or the negatives So when they take those scripts to The Javascript If you make a simple mistake It will transport data into those errors so there

okay but how do I make it so the game works but i can convert it?

Argument sandboxId for data.sandboxId is missing.

https://scratch.mit.edu/projects/829354774/ why doesnt this work

hello.
I tried to convert my project to javascript but it didn't work.
the project is in scratch 3.0 and has no extentions.

what can I do?

project: https://scratch.mit.edu/projects/1000718832/

Hi, So I have a cool project i am making, and I wanted to make it on a different game engine without going through 18 hours of work, but whenever I try to convert it, the only way that has worked was an html convert, but then when I try to convert the HTML to java or javascript, it gives me an error, like everything else. I don't know whats wrong with it, because I think it's supposed to work with the web version of today. Could someone please tell me what I am doing wrong? Leopardjs gave me an error when i uploaded it and gave it the link and it said “Argument sandboxId for data.sandboxId is missing.”
Here is the project: https://scratch.mit.edu/projects/942467711

Also I really hope it's not because of blank values because this won't work without them

im just gonna bump this to encourage discussions

this one doesn't work for some reason:

the only extension if pen

when I receive [question v]
repeat until <(answer) = (correct answer)>

Good news! There is now a solution for the “Argument sandboxId for data.sandboxId is missing” message.

Have you ever tried converting a project and seen an error like this?


Well now there is a solution. This error appears when your converted project cannot be uploaded to CodeSandbox. Now, instead of converting on the cloud, there is a new feature: You can now convert Scratch projects to Leopard code locally, on your own computer. You don't need to use the leopard website and you don't need to use CodeSandbox.

Here's how it works. Under the hood, we've created a library called “sb-edit” that converts projects between different Scratch file formats. In this case, from a .sb3 Scratch project file into Leopard code. This tool now has a command-line option that lets you run it from your very own computer's terminal.

To run the terminal converter, there are just two steps.

First, use npm to install the sb-edit package globally (so it can be used from anywhere on your machine).
(If you don't have node/npm or haven't used it, it is a tool that helps you run JavaScript code, like sb-edit, from the terminal on your computer. To get npm, install node.js from the official website. When you install node, the npm package manager will come with it.)

Then, you can convert a .sb3 file (which you can download from the Scratch editor by clicking File > Save to your computer) to a Leopard project using the following command:
This command will take your input sb3 file and generate a folder full of Leopard code at the output directory you specify. Obviously, you should edit the input and output paths in the command above to match the actual locations of the input file and desired output folder on your computer.

If you want to generate a .zip file instead of a folder, you can do that as well. Just set –output to be a path with a .zip filename.

That's right! Translating Scratch to JavaScript is now possible! The tool is called Leopard, and it's available here:

Leopard Website – Go here to convert your projects!

Who needs this?
Scratch is amazing. This is the place where I learned to code almost 9 years ago. I love the Scratch community, and the fact that it's so easy to get started with Scratch. However, many of the features that make it easy to start using Scratch also make it underpowered for more experienced programmers.

With a different programming language like JavaScript, you get:

• More features: You can do cool tricks that simply aren't possible with Scratch.
  
• Speed: Your projects run faster and lag isn't as problematic.
  
• Publishing options: Run your projects on any website, not just Scratch.
  

If you want to try a different programming language but find it difficult to get started, Leopard can help.

How is this different than Phosphorus?
Phosphorus is awesome, but it's a little different than Leopard. With Leopard you can view and edit the translated JavaScript code yourself.

What if it doesn't work?
Not every project will translate perfectly.

• Only projects created using Scratch 3.0 can be translated. If you created your project using Scratch 2.0 or older, you'll need to open it up in the Scratch 3.0 editor, make a small change, and then try again.
  
• Some Scratch blocks are not yet supported. Check the translations page to see which blocks have JavaScript equivalents using Leopard. More blocks will be supported over time.
  
• Extension blocks won't work (except pen, which works great!)
  
• Sometimes there are little inconsistencies. We've done our best to make sure Leopard behaves exactly the same as Scratch, but there will always be little cases we haven't considered. It's possible that your scripts will run slightly out of order, be a little too fast, or some other issue. Fortunately, you can edit the JavaScript code to fix those issues, and I'm happy to help.
  

Thank you so much to the contributors who made Leopard possible!

you can also use turbo warp: https://turbowarp.org/

Non translated list:

when backdrop switches to [backdrop 1 v]
set drag mode [draggable v]::sensing 
set drag mode [undraggable v]::sensing 
([volume v] of [Sprite1 v])
(username)
(☁ cloud variables)

- extensions other than pen

I have translation for makey makey block:

when [space v] key pressed::pen

new Trigger(Trigger.KEY_PRESSED, { key: “space” }, this.myScript)

Translations of two hacked blocks:

while <> {}::control 

while ((/* condition */)) {
// do something fun here
yield;
}

loud::sensing boolean 

this.loudness > 10

New idea for username:

set username [user]::sensing 

javascript:
This.username = user
Default username: user
Scratch compatiblity idea:

leopard.set username [user] 

All custom blocks with this name are replaced with this javascript.

Does Leopard also convert the costumes/art into javascript, or just the code?

The costumes and sounds stay the same. In your converted project, they are just stored as files. And those files can be read and displayed using JavaScript code.

None of my projects work, idk why
