Guide to Modding Scratch 3.0

You're telling me Scratch modding exists? But why?

I wanted to make a mod for making games easy.

I would like to individually address clones and iterate through a list of all clones of a certain sprite. Also, I would like some vector math blocks to make physics easier for younger students of math (ie, move toward or away from something by changing x and y rather than changing directions, also an “orbit” block so you can make circles around something.) Also, I would like to be able to store a sprite or specific clone as a value of a variable so sprites can keep a reference to other objects they may have a special relationship to.

With 2.0, I had added the ability to add “tags” to a sprite or clone and the ability to change the private variables of sprites and clones from another sprite or clone's scripts or from the background's. So you could tell the background to make all objects with tag “feels gravity” fall, and dynamically add or remove that tag from sprites or clones so they would fall or not fall depending on when they have the tag.

Another nice feature would be to have sprite lists so you treat some sprites as weapons and some as obstacles just based on which list they are in - an alternative to the “tag” thing. So some sprites could be in the “menu” list and some in the “world” list - so you could have separate scripts run through each list doing different things.

What do I do I run scratch on C++ how am I going to mod if I don't use JavaScript. I also don't know javaScript

I think they should just add a tab that says import files and you have a mod file rather than having to copy scratch code and go through all of the coding which I have no clue about and don't understand. That would just make a lot of sense if there was just a tab that said mod here. and you could import the correct type of file(s).

Edit: nvm

here from 6 years after this post (and 1 day after the last one)
two errors doing yarn prepublish on scratch-blocks:

Can't resolve ‘../blockly_compressed_vertical’ in ‘F:\snatchKit\scratch-blocks\shim’
Can't resolve ‘../blockly_compressed_horizontal’ in ‘F:\snatchKit\scratch-blocks\shim’

if anybody knows how to fix this, please say so

A question: Can I replace the python and JavaScript code with equivalent C++ code to make it faster?

I attempted to npm install the blocks, but all I get is:
