adding conditions

pinochio · October 14, 2009

Hi guys,

I need to add a "colder/hotter" ( children game when you get closer = it is hotter and etc) condition into a guess number game. Any ideas how can I add this condition?

Thanks a lot !

  <BODY>

    <SCRIPT language = "javascript" type = "text/javascript">
   

      //Define script variables
      var randomNo = 0;
      var gameOver = false;
      var keepPlaying = false;
      var guess = "";
      var msg = "I am thinking of a number from 1 - 100. Try to guess it:"
      var reply = "";
    
      //This loop allows the player to play as many games as desired
      while (gameOver == false) {

        randomNo = 1 + Math.random() * 99; //Generate a random number
                                          //from 1 - 100
        randomNo = Math.round(randomNo);  //Turn the number into a integer

        keepPlaying = false;  //Set value to indicate that the current
                              //round of play should continue
   
        //Loop until the player guess the secret number
        while (keepPlaying == false) {

          //Prompt the player to guess the secret number
          guess = window.prompt(msg);

          //Analyze the players guess
          if (guess == randomNo) {   //See if the player guessed the number

            window.alert("Correct! You guessed the number.");
            reply = window.prompt("Would you like to play again? (y/n)");

            if (reply == "y") {  //See if the player wants to play again
              keepPlaying = true;
              gameOver = false;
            } else {             //Let the current round of play continue
              keepPlaying = true;
              gameOver = true;
            }
          } else {
            if (guess > randomNo) { //See if the player's guess is too high
              window.alert("Incorrect. You guess was too high.");
            } else {                //See if the player's guess is too low
              window.alert("Incorrect. Your guess was too low.");
            }
          }

        }
      
      }
   
      window.alert("Game over. Thanks for playing.");  //Thank the player

As well as the variable guess, create another variable previousGuess.

Just before you ask the user for their next guess assign guess to previousGuess, then when they have made the new guess compare the difference between their new guess and the target number with the difference between their previous guess and the target number.

Something like:

previousGuess=guess;
guess = window.prompt(msg);
var newDiff = randomNo-guess;
var previousDiff=randomNo-previousGuess;
if(newDiff < previousDiff){
    alert("warmer");
}
else{
    alert("getting cooler");
}

But then you need to put in another check to see if the guesses are higher or lower than the target

              gameOver = true;
            }

              window.alert("Incorrect. Your guess was too low.");
            } else {
           if( newDiff < previousDiff){
                          alert("warmer");
             } else {
                 alert("cooler");
            }
          }

        }
     
      }
   
      window.alert("Game over. Thanks for playing.");  //Thank the player

Because you have this at the top of your code.

var guess = "";
var previousGuess=guess;

Previous guess will always be equal to a blank value.
