Write scratch - with text?

jumpingtj

Hi! This might not be the right forum, but…

I've been looking into the sb3 format. It's just a zip with projects assest, but also a project.json file that contains the code.
Is it possible to write this project.json file using Python? And for the syntax, scratchblocks already exists - it could piggyback off that?
But at that point we could probably steal the parser for scratchblocks so could piviot to JS.

I'd be happy to write in Python, JS or Go - JS using scratchblocks syntax might be the way.

Any ideas?

Thanks,

There is a list of text-based Scratch applications, most of which are in beta (or haven't been updated to 3.0 yet), although all of them are usable.

So it's definitely possible.

Note that per section 4.4 of the Terms of Use, you cannot upload any projects created with a Python script. The projects must be user generated with an unmodified Scratch editor.

That doesn't mean creating Scratch projects in those ways isn't allowed, you just can't upload those projects.

4.4 You may only submit user-generated projects that were created with (1) the Scratch website editor or (2) an unmodified copy of the Scratch editor compiled from the source code described in Section 5.3. You may not upload any projects that were created, by you or by anyone else, with a modified version of the Scratch editor.

The Scratch Team is kind of lax enforcing this (especially if you count that 5.3 talks about the 1.4 editor…) but just be aware this is in the ToU.

although - this is not regularly enforced and it's probably only there because they want all projects hosted on the scratch website to be playable with vanilla scratch. (eg. they don't want you piggy backing off of scratch's hosting to make projects that only work elsewhere)

there's a project that sounds like something you're looking for: https://github.com/DavidBuchanan314/boiga. it lets you write scratch projects like this

from boiga import *
project = Project()
cat = project.new_sprite("Scratch Cat")
cat.add_costume("scratchcat", "examples/assets/scratchcat.svg", center=(48, 50))
cat.on_flag([
	Say("Hello, world!"),
])
project.save("examples/out/Boiga Examples: Hello World.sb3")
