Guessing Games (Repeat, Exit, Random) (code - Guess)

You can make a number guessing game. You are going to pick a number and see if someone can guess it
(The finished Guess game is below under "files". It is a LiveCode file that you can download and use)

1. Open a new mainstack and add a button on it called "Guess"
2. Add the following code to the button:

           on mouseUp
                   local myNum
                   put 40 into myNum
                  ask "Guess my number"
                  if it = myNum then
               answer "Your Guessed it"
                  else
               answer "Wrong, that is not it"
                  end if
           end mouseUp

Now run it. We made our number 40 and put it into a variable that we named "myNum". The problem is they only have one guess to guess it. We want to fix it so they can keep guessing until they guess it. We also want to allow them to "cancel" or quit if they get tired guessing

We will add a variable called "guess" to save their guess into. We will also add a "repeat" statement to repeat everything until the guess the number.

Change the code to read: (Repeat)

on mouseUp
       local myNum,guess
      put 40 into myNum

      repeat until guess = myNum
       ask "Guess my number"
       if it is empty then exit repeat
       put it into guess

          if guess = myNum then
          answer "Your Guessed it"
       else
          answer "Wrong, that is not it"
       end if
      end repeat

end mouseUp

This is better but let's give them a little help by telling them if their guess is "high" or "Low". Let us also make sure they exit the repeat after they guess it. (Exit)

on mouseUp
   local myNum,guess
   put 40 into myNum

   repeat until guess = myNum
ask "Guess my number"
if it is empty then exit repeat
put it into guess

if guess < myNum then

answer "You are too low, guess higher"
end if

if guess > myNum then
answer "You are too high, guess lower"
end if

  if guess = myNum then
     answer "Your Guessed it"
         exit repeat
  end if

end repeat
end mouseUp

Now let us let the computer pick a random number for us to guess. We will tell it to pick a random number from 1 to 100. (Random)

on mouseUp
   local myNum,guess
   put Random(100) into myNum

   repeat until guess = myNum
ask "Guess my number"
if it is empty then exit repeat
put it into guess

  if guess < myNum then
   answer "You are too low, guess higher"
end if

if guess > myNum then
   answer "You are too high, guess lower"
end if

  if guess = myNum then
     answer "Your Guessed it"
     exit repeat
  end if

   end repeat
end mouseUp

It works but we have too many pop-up boxes. Let us change the 'answer' to 'ask' and get rid of the other ask.

(When you write a program, after you get it working you sometimes see a better way to do it).

on mouseUp
   local myNum,guess
   put Random(100) into myNum
ask "Guess my number"
put it into guess

   repeat until guess = myNum

         if guess < myNum then
        ask "You are too low, guess higher"
                 if it is empty then exit repeat
            put it into guess

end if

if guess > myNum then
ask "You are too high, guess lower"
if it is empty then exit repeat

end if

  if guess = myNum then
answer "Your Guessed it"
exit repeat
    end if
   end repeat
end mouseUp

Good work. We now have a fun guessing game
