How do I find the number of words in an answer, like the:

ask [] and wait

block? like if the answer was “hello world”, how would I count the words?

Go through a string, adding every letter to the same line. When you encounter a space, add a new line and start adding to that instead. Remove all blank values in the list, and just use the length of the list.
Here's an example:

define wordCount = number of words in (input)
delete (all v) of [count v]
set [i v] to (0) // keeps track of what letter we're at
repeat (length of (input))
change [i v] by (1)
if <(letter (i) of (input)) = [ ]> then // that's a space (" ")
add [] to [count v] // this is blank, not a space
else 
replace item (last v) of [count v] with (join (item (last v) of [count v])(letter (i) of (input))) 
end
end
set [i v] to (1) 
repeat (length of [count v])
if <(item (i) of [count v]) = [ ]> then // that's a space
delete (i) of [count v]
end
change [i v] by (1)
end
set [wordCount v] to (length of [count v]

here's what I did

when green flag clicked
ask [What's your name?] and wait
set [word count v] to [0]
set [i v] to [1]
repeat until <<not <(letter (i) of (answer)) = [ ]>> or <(i) = (length of (answer))>> 
  change [i v] by (1)
end
repeat until <(i) = (length of (answer))> 
  repeat until <<(letter (i) of (answer)) = [ ]> or <(i) = (length of (answer))>> 
    change [i v] by (1)
  end
  change [word count v] by (1)
  repeat until <<not <(letter (i) of (answer)) = [ ]>> or <(i) = (length of (answer))>> 
    change [i v] by (1)
  end
end

it doesn't separate the words and put them in a list, just gives you a word count. It should work even if the answer has multiple spaces at the beginning, middle or end which I think might break the example above (although I haven't tested it)

Please

If you are using it to make noises for the amount of characters that there are in an answer, then, use this:

repeat (length of (answer))
play sound [pop]
end

Otherwise, use the other methods

and sorry, i never checked the time this was posted.
