So I am working on a huge project for school (512MB Scratch file). I need to have a random number generator assign a number to each “subscript”. How would this be possible.

I'm a bit confused about what's a subscript. Could you describe one? Also, more out of curiosity, how is your project 512 MB?

Really curious,

I'd suggest you make a list for all the numbers you need. that way when you hit that number, you can delete said number from the list so you can't hit it again.
Here is what I'm trying to say..

when green flag clicked
set [Number v] to (item (random v) of [list numbersv])
say (Number) for (2) secs
delete ((Number) v) of [list v]

Its a quiz for spanish and I was not very efficient and I don't want to change the source code right now

Ok. Just an idea.

Phht! Sorry, I was on my sister's account accidentally…

512MB! THIS IS SCRATCH, DO YOU KNOW HOW BIG 512MB IS (524288KB)?

 <(512MB)=(524288KB)> 

You're computer is probably going to crash considering it's scratch and it's 512MB. Do you mean 512 assets?

when green flag clicked
repeat (50)    
set [Numbers v] to (pick random (0) to (10000))
insert (Numbers) at (1 v) of [list hi v]
if <[hi v] contains (Number)> then
Repeat last step
    
end
end

Hope this helps

Above works, for really simple try

when green flag clicked
forever
repeat until <not <(output) = (prevoutput)>>
set (output) to (pick random (1) to (10))end
set (prevoutput) to (output)

This will never give the same number as the last one, but it can every 3rd number it gives.

do this to make a list of numbers in order:

set [counter] to [0]
repeat (however many random numbers you want)   
change [ counter] by (1)
add [counter] to [list of unused numbers]
end

then, you will have a list of numbers from one to whatever. Then, you do this to pick one that has not been used:

repeat until <not <[number you are currently using] = [used]>>
set [number you are currently using] to [(item ((pick random (1) to (length of [list of unused numbers]))v) of [list of unused numbers])]
end
replace item (number you are currently using) of [list v] with [used]

repeat that to pick numbers

OPTIONALLY, you can do this instead after you have your list of numbers:

repeat until <(length of (list of unused numbers)) = [0]>
    set [list item being used] to (pick random (1) to (length of (list of unused numbers)))
set [active number] to (item (list item being used) of [list of unused numbers])
delete (list item being used) of (list of unused numbers)
end

with this, you don't have to wait teh few seconds it would take to hit-and-miss for an unused number.

First, you need to create 2 lists. One called numbers and one called use. The numbers list contains numbers 1-9. We will leave the other list empty for now. Also a variable called last. Here is the script:

//put you trigger here
set (last) to (join (item (random) of [numbers]) (item (random) of [numbers]) )
say (last) for () secs
add [last] to [used]
forever
 set (last) to (join (item (random) of [numbers]) (item (random) of [numbers]) )
if <not <[used] contains [last]>> then
say (last) for () secs
add [last] to [numbers]
end   
end
//you will put as many seconds as you need
//also, you can put joins inside of each other, so put as many joins as you need digits. I just used 2 as example here

Hope this helped you. Tell me if it did.

I've seen bigger, and it works on my laptop.

I have a question! where are these red parts you guys used in your scripts?????

Red blocks are just things that Scratchblocks doesn't recognise so someone has entered something incorrectly or deliberately indicated the space where whoever wants to use the script should insert their own code.

what is the red piece?

It would be nice if you read through the whole topic before commenting! It's forum etiquette!

Literally the post above yours explains the red piece:

If you're posting because you didn't understand that explanation, a red piece is what happens when you make a Scratch block on the forums that doesn't actually exist in Scratch.

Like this:

obsolete!

It's best to make your own topic if you're going to ask something that has nothing to do with the title.
Finally, don't necropost! It means posting on an already resolved question, or one that hasn't seen active replies in a long while.

Try to follow these general rules as well as you can; they help make the forums run more smoothly!
