How to make Scratch extensions whose projects can be opened in normal scratch?

50_scratch_tabs

How can I modify Scratch-GUI to make Scratch extensions whose blocks show up as custom blocks when a project is opened in regular scratch? Kind of like the

<Is TurboWarp? :: custom>

block… It can be imported into regular scratch, it just won't do anything.

If you have a signature that requires Shift+down, paste this at the bottom of it. If you actually read this far, you deserve my respect. -50_scratch_tabs

The is TurboWarp? block isn't actually an extension block, it's just a custom extension argument reporter.
For the vanilla palette, add something like this to src/lib/make-toolbox-xml.js:

<block type="argument_reporter_boolean"><field name="VALUE">boolean block name</field></block>

or

<block type="argument_reporter_string_number"><field name="VALUE">reporter block name</field></block>

You could also make stack blocks using custom block call blocks:

<block type="procedures_call"><mutation proccode="stack block name" argumentnames="[]" argumentids="[]"></mutation></block>

Then to implement the code, modify the code for the argument reporters/call blocks in scratch-vm. For example, you can look at TurboWarp's code:
implementation in the interpreter
implementation in the compiler

This is a signature. It's a piece of text that appears below every post I write. Click here to learn more, including how to make your own.

Getting survey popups that look like this? It's normal, and is a thing the ST is doing. Read this topic for more info.

Can I make this with a Javascript addon? I've never messed with Scratch's default blocks, only created new extensions.

I did in a Scratch-gui mod, not Turbowarp.

Nevermind, reread your post.
