Blackjack game is driving me crazy

24 Jul

I’ve been working on the blackjack name for codecademy all day today without luck.  The challenge / puzzle / assignment is to have a hand of cards generated and scored.

The hand is an object that includes two ‘card’ objects. each card is generated randomly with two features (number and suit*).The suit is defined by a random number 1-4 and defined by a method for matching this numeral to a suit. The number is defined as 1-13 and set to values such that 1 (ace) = 11, 1-10 =face value and 11-13 are face cards worth 10pts each.

 

I simply can’t do it. My code looks reasonable to me (but I don’t really feel comfortable with it at all), but I’m getting crazy results. Here’s what I have, try copying it into a javascript field and see if you can make heads or tails of it:

 

// Make your card constructor again here, but make sure to use private
// variables!
function Card(s,n){
this.number = n;
this.suit = s;

this.getSuit = function(suit){
//console.log(“I’m about to switch”);
switch (this.suit){
case 1:
this.suit = “clubs”;
break;
case 2:
this.suit = “diamonds”;
break;
case 3:
this.suit = “hearts”;
break;
case 4:
this.suit = “spades”;
break;
}
}

this.getValue = function(number){
if(this.number === 1){
//console.log(“value = 11”);
this.value = 11;
return 11;
}
else if (this.number >=11){
//console.log(“value = 10”);
this.value = 10;
return 10;
}
else{
//console.log(“value = “+ this.number);
this.value = number;
return this.number;
}
};
};

// Make a deal function here. It should return a new card with a suit
// that is a random number from 1 to 4, and a number that is a random
// number between 1 and 13
var deal = function(){
var suit = Math.floor(Math.random()*4)+1;
console.log(suit);
var number = Math.floor(Math.random()*13)+1;
console.log(number);
return new Card(suit,number);
};

var Hand = function(){
this.card1 = deal();
console.log(“card1 is “+card1.number+ ” of “+card1.suit);
this.card2 = deal();
console.log(“card2 is “+card2.number+ ” of “+card2.suit);
};

Hand();
console.log(Hand);

 

 

*by the way, it is clear that there is nothing that prevents the same card from being drawn twice from what presumably is a single deck.
