Even or Odd number sorter
I am working on a project where scratch generates ten random numbers and puts them in a list. Whenever you press s the numbers are supposed to be sorted into 2 different lists even and odd. How do i sort the numbers.
this is what i have so far

I made a “game” that does what I think you want, I couldn't look at your game because of time constraints.
Here is the link! I will explain this when I get home.

One way is to take the number and divide it by 2, then see whether the answer is a whole number.
So 3 divided by 2 is 1.5 (not whole) but 10 divided by 2 is 5 (whole)
Get Scratch to find whether it's whole by comparing the result with the rounded-down result. If they're the same, it was whole to start with.

Or use the mod function. N mod 2 is 0 if N is even and 1 if N is odd.

when green flag clicked
set [odd v] to [1]
set [even v] to [2]
repeat ([half v] of (...)::operators)
add (even) to [even2 v]
change [even v] by (2)
end
repeat (...)
add (odd) to [odd2 v]
change [odd v] by (1)
end

Doesn't match the question which was about 10 random numbers - otherwise a good method to create odd and even lists.when green flag clicked
set [odd v] to [1]
set [even v] to [2]
repeat ([half v] of (...)::operators)
add (even) to [even2 v]
change [even v] by (2)
end
repeat (...)
add (odd) to [odd2 v]
change [odd v] by (1)
end

Maybe change odd by 2.Good spot, I didn't check it that closely.
No real need for two variables either. Just increase one variable by 1 each time you save it and save once to odd and once to even each time through the loop.

How do you make the numbers touch the wrong bowl and it explodes???

I am working on a project where scratch generates ten random numbers and puts them in a list. Whenever you press s the numbers are supposed to be sorted into 2 different lists even and odd. How do i sort the numbers.You want to sort an existing list (list), and sort it into two lists, (odd), and (even).
this is what i have so far
https://scratch.mit.edu/projects/178918750/
when green flag clicked
repeat until <(length of [list v] :: list) < [1]>
if <((item (1 v) of [list v] :: list) mod (2)) = [0]> then
add (item (1 v) of [list v] :: list) to [even v]
else
add (item (1 v) of [list v] :: list) to [odd v]
end
delete (1 v) of [list v]
end
This basically repeats until the “list” is empty. Until it is, it checks if it’s odd or even. (Using modulo!) It then adds it to the even, or odd list. Finally, it deletes the number it just sorted. (That was a horrible explanation, I know.)

when I receive [ sort numbers]
repeat (10)
if <[(((item (1) of [numbers] :: list)) / (2))] contains [.] ?> then
add (item (1) of [numbers] :: list) to [odd numbers]
else
add (item (1) of [numbers] :: list) to [even numbers]
end
delete (1) of [numbers]
end
My way of doing it. I would normally use the operator contains though, not the list one (I couldn't find the green one).

Well I can't get the scratch blocks to work but what I normally do is divide the number by two, and if it contains a period/dot, then it must be odd. Then you just go from there

An even and odd number sorter can work like this(WARNING! THIS ONLY WORKS IN SCRATCH 3.0):
define Sort(numberList :: custom-arg)Because if you divide 3 by 2, you get a result of 1.5. 1.5 has a decimal point which this code is built to detect. This only works for strings though.
set [counter v] to [0]
delete (all v) of [odd v] :: list
delete (all v) of [even v] :: list
repeat (length of (numberList :: custom-arg))
change [counter v] by (1)
if <((letter (counter) of (numberList :: custom-arg))/(2)) contains [.]? :: operators> then
add (letter (counter) of (numberList :: custom-arg)) to [odd v]
else
add (letter (counter) of (numberList :: custom-arg)) to [even v]
end
end

try this if you want a simple boolen to find if it is even of odd. true=even false=odd. replace 3 with the number you want to find if it is even or odd:
