Good question indeed

My browser / operating system: Windows NT 10.0, Chrome 126.0.0.0, No Flash version detected

Hello, I have a project it am trying to convert to js but im not sure why it gets the error where “Cannot read properties of undefined (reading ‘value’)”
i am really not sure why this happens, and here is the link to the project i am trying to convert so maybe you can try to do it yourself. (if it works on our side somehow)

Link here!

According to forums that help in debugging JavaScript, “Cannot read properties of undefined (reading ‘value’)” means that a variable was not initialised, but I figured that there would be no reason why this will happen as I don't think that the converter will run a piece of code that will have a error in it, but I did not design leopardjs, so correct me if I am mistaken.
Please help!

If you create a project using the “Leopard Editor” option in the dropdown menu, the translations will be available at the bottom of the screen.

The canvas is 480x360 but you can scale it up or down using CSS by setting width: 100%. But if you take the small stage and scale it up to be way bigger it might become blurry. So you can also change the actual stage coordinates to be larger like this.

A Scratch to Python version of Leopard would be really cool. (suggestion)

okay ive posted on this topic a lot but i wanna say this is the most fun ive ever had with a javascript game engine. thank you pulljosh for making it

https://leopardjs.com/users/dumorando heres some projects i made with it

My project doesn't seem to work.

https://scratch.mit.edu/projects/1052429835/

I can't convert it from an sb3 file, and when I try to download it in zip format, I get the following error.

{“error”:“Cannot read properties of undefined (reading ‘value’)”}

What should I do?
(The assets are small, 3.5MB, and the json file is 2MB, with list data taking up about half of it.)

You should check out Patch! My friends at BX Coding are working on it.

That's a great question! If you're willing, it would be great if you would post this under “Cleanup Crew” for the Leopard mentors to investigate.

I am so glad to hear that!

I really love your localStorage project. That's a fantastic way to show off the features of JavaScript that are impossible to do in Scratch. There should really be a way to show off excellent projects like this to the community. I might work on adding some kind of “featured projects” area to the front page…

Apparently the block that specifies the pen color (saturation, brightness, transparency) was not converted properly, which caused the error…

I tried to transfer my project thirdly into JavaScript using leopard, but it lead to an error. This project only uses the one extension, which the error code said it supports. What is the reason for the error?
