I am new to coding and trying to do something relatively simple. I would like to make a game where random numbers are displayed. If the correct number is typed in, then I would like a new number to be shown. If the number typed in is wrong, I’d like the player to have to try again. I would like this process to repeat 6 times. Could someone explain what I’m doing wrong?
Also, eventually I would like to replace the dialog box with pictures that are clicked. I assume that I need to make an array delineating the pictures as variables and enable these pictures to receive clicks in xcode’s interface builder?
Thanks so much!
on run
set c to 0
try
repeat
play()
feedback()
set c to c + 1
if c = 6 then exit repeat
end repeat
end try
end run
on play()
set a to random number from 1 to 5
set r to run script (a as text)
set u to text returned of (display dialog (a as text) default answer "")
end play
on feedback()
repeat
if (u as string) is not (r as string) then
set u to text returned of (display dialog (“Try again” & space & a as text) default answer “”)
else
display dialog “Well done!” buttons {“Cancel”, “Continue”} cancel button 1 default button 2
end if
end repeat
end feedback
Your functions aren’t returning anything. You are making some assumptions about the scope of variables U and R that just don’t work, unless you declare them as global, which might be overkill here.
This works but gives a repeating loop once answered correctly. I could fix it, but it might be helpful for you to take a look and understand why that’s happening now.

hint: you might have to get the value of a button to exit…
Thanks. I think I have that part worked out, but now it doesn’t progress to show another number. I can’t seem to figure it out!

Hi. Here is an alternatively structured version, for learning purposes. I took out a couple things; the incremental counter at the beginning of the script can be a specified count, and the explicit “return” in the handlers isn’t needed, since the implied value is it. I also chose to nest the handler calls.
repeat 2 times
feedback(play(randNum()))
end repeat
on randNum()
random number from 1 to 5
end randNum
on play(aNum)
{(display dialog (aNum) default answer "")'s text returned} & aNum
end play
on feedback({this, |that|})
repeat
if not this = |that| as string then
display dialog "Try again" buttons {"OK"} default button 1
feedback(play(randNum()))
exit repeat
else
display dialog "Well done!" buttons {"Cancel", "Continue"} cancel button 1 default button 2
exit repeat
end if
end repeat
end feedback
Thanks! That makes a ton of sense. Now all I need to do is figure out how to link that to pictures so the kids can click on a picture and get feedback…I’ll keep chugging along!
Thanks!
