Wow, awesome! I don't know any JavaScript so I'm using this to help me learn a bit. Quick question though, how would you make an “if on edge, bounce” function because I kind of need it.
Look below

DO this Script
if (/* this.touching(“edge”) */) {
//bounce (maybe)

I hope this helped and I don't know as much so sorry if it doesn't work

Mine wont convert, it keeps saying "Cannot read properties of undefined (reading ‘name’)"

Error:
There was an error converting your project.

Error occurred during query execution: ConnectorError(ConnectorError { user_facing_error: None, kind: QueryError(Error { kind: Db, cause: Some(DbError { severity: “ERROR”, parsed_severity: Some(Error), code: SqlState(E42P05), message: “prepared statement \”s0\“ already exists”, detail: None, hint: None, position: None, where_: None, schema: None, table: None, column: None, datatype: None, constraint: None, file: Some(“prepare.c”), line: Some(446), routine: Some(“StorePreparedStatement”) }) }) })

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!

here's my if on edge bounce block replacement
if (this.y > 180 || this.y < -180 || this.x > 240 || this.x < -240) {
this.direction += 180;

Why does it not support extensions other than pen! Scratch was coded with JavaScript! The extensions were coded with JavaScript!

Fun news! Thanks to some hard work from HanClinto, towerofnix, and adroitwhiz, we now support the “if on edge, bounce” block!

if on edge, bounce

This completes our support for the Scratch “motion” category! All motion blocks are now supported in Leopard.

Great job keeping this project active for all these years!

Scratch uses a JavaScript library called the Scratch VM. Extensions in Scratch are written to work with the Scratch VM. Leopard does not use the Scratch VM, at least to my knowledge

Leopard.js won't upload my project. It was made in 3.0, last week in fact. No idea what's wrong.

It's because there's no support for the "stop [other scripts in sprite v]" block

Followed your examples on the sb-edit github page. Was able to get code from .sb3 file using your call to project.toLeopard({ printWidth: 100 }).
Looking at the code for the toLeopard function, looks like there are options for extracting costumes, backdrops and sounds.
Is that possible and if so, how would I set the options for the call to toLeopard to do it?

What do you mean by “extracting” costumes, backdrops, and sounds?

It says sometimes it messes up converting when your game uses pen. Is this true?

Pen blocks shouldn't cause an issue. Other extensions might be a problem, but pen is fully supported. Are you seeing any pen-related errors when you try to convert your project?
