SB3 to SB2 Converter (working)

I've just finished writing an SB3 to SB2 converter in Python 3, which can be found here: https://github.com/RexScratch/sb3tosb2

If you find any bugs or issues, please tell me. This is also the first time I've written something like this, so I'd appreciate feedback on how to improve the code.

Just tried it on simple project and it worked

https://scratch.mit.edu/projects/287498438

Minor issue - script wasn't visible in scripting area until I'd done a right-click cleanup

WELL DONE

It was visible for me, although it was shifted to the right. (My screen is 1080p)

How do you handle blocks that don't exist in 2.0?

I hope my post helped you in some way! Post count: 500+

Current project: [s3Blocks: scratchblocks rewritten for Scratch 3.0] ::#4b4a60 //https://scratch.mit.edu/discuss/topic/290031/ Basically done!

It just creates an undefined block with the original inputs and fields.

Some blocks don’t exist but are converted by using a different block and modifying the input, such as
set pen [brightness v] to (input) :: pen stack
set pen shade to ((input) / (2))
...
go to [back v] layer :: looks stack
go back (1.79e+308) layers // ignore the variable reporter
...
go [forward v] (input) layers :: looks stack
go back ((-1) * (input)) layers

SVG fill issues have been fixed, although text still doesn't show up properly and the stroke width is often incorrect.

A major missing feature has been added: SVG text conversion. Text in vector images will no longer disappear when converted.

Hi. I tried to use your converter, but after it finished converting “successfully”, the SB2 file I got was blank. Do you know why this is? Is there an error on my behalf?

Could you share the sb3 file?

How would I do this? Even so, do you promise not to post it? I've been saving this particular project for a while…

Well, the before doing that, ensure that you've downloaded the latest version. Then run the py file and save the sb2 file to wherever you want using the file dialog. Make sure to open the correct sb2 file afterward. Also, it might help if I knew your Python version. Also, make sure you wait for the Scratch 2.0 editor to fully load, because it shows an empty project before the opened project is fully loaded.

1. I'm using Python Idle 3.7.2
2. I did let it fully load. The X,Y coordinates were moving (when my mouse moved) and only a default project displayed for over a half an hour.
3. I have now tried with multiple projects to get the same result of a blank project file.

What's the file size of your sb3 projects? The program works fine for me (I downloaded it just to test)…
Also, don't use IDLE. Right-click the py file and run it using python instead (or run it from the command line).

Opened in Python, same result occured. Now I've noticed that the file won't even load. Nothing is overwrited.
