First, I need to understand what “null” is. I've seen it a lot in JavaScript, but I don't understand it.

Null in programming languages ​​(e.g. the above-mentioned Java Script) means nothingness.

This could be useful. Semi-support.
I don't feel like adding more to that because I'm too tired to think.

There is no such thing as necroposting in the suggestions forums

This is true, as long as it contributes to the topic. Lets stay on topic though.

After doing some research, it looks like it returns “true” all the time (I might be wrong). This looks like it could be useful. As I said, it returns true all the time, but couldn't it be replaced with this?:

<(foo) = (foo)>

Please tell me if I have the wrong definition. I will share more then.

what about this?

stop [ other scripts in sprite v]

This is meant to stop a currently running script; you're thinking of a reporter. Null is actually a falsy value; It returns ‘false’ (or, at least, is converted to that), not true.

So like this?:

if <> then
stop [this script v]
end

Null is actually a falsy value; It returns ‘false’ (or, at least, is converted to that), not true

So:

<not <(foo) = (foo)>>

Necroposting is not a thing in this forum.

I don't fully understand what this is supposed to even be or how it would be implemented. It's one of those that would be confusing for both new scratchers and the Scratch Team.

And Scratchers

All null blocks I know

say []
<<> and <>>
set pen color to []

Historic:

loud?
sensor (☁ score)

full code:

when green flag clicked
if <loud?> then
stop [all v]
end

when [. v] key pressed
go <sensor [hi]>

(there is a fake block! can you spot it!)

blocks:

. . . //describes that nothing is happening

[] //a custom block that is empty

all at once //this is useless however it can be used to delete clones instantly
null [] //this I think just turns the script null

“Null” isn't a very descriptive name for this block- I couldn't guess what it does without trying it out! I would name it “stop selected script” instead.

No other block requires you to select a specific script as input- this strikes me as potentially very confusing to new users.

In all the use cases I can think of, it would be better to use variables, or maybe a dedicated sprite running “stop other scripts in sprite”. Do you have a particular use in mind?

What would this do?

this is still possible
