Card Game For Sphere

[Hero of Time Link³]

I found this tutorial off the internet for card games.

So you want to create a card game...
It's as easy as you want it to be.

You have a deck of cards in the middle of the table.

var card_deck = new Array();

Wow, now you have a deck (albeit empty) on the game table.

Now you need some cards.
This can be as simple or as difficult as you want it to be, for example:-

var card = 0; // the first card

Or:

function Card(suite, number) {
this.suite = suite;
this.number = number;
}

var card = new Card("Hearts", 0); // ace of hearts

The first method, you have to remember what card it actually is.
The second method, is probably easier, but we'll go for the first method for now.

So before we start the game, we need to place all the cards down in the deck...

function RandomSort(temp)
{
var sortedArray = new Array();

for(var i = 0; i < temp.length; ++i)
{
var n = Math.floor(Math.random() * temp.length);
sortedArray.push(temp[n]);
temp.splice(n, 1);
}

return sortedArray;
}

var card_deck = new Array();

function init_card_game() {
card_deck = new Array();
for (var i = 0; i < 52; ++i) {
card_deck.push(i);
}
card_deck = RandomSort(card_deck);
}

So now, how many players do we have in the game, how many cards do they get each?

var num_players = 2;
var num_cards_each = 7;

var players_hand = new Array();

function DealDeck() {
players_hand = new Array(num_players);

for (var i = 0; i < players_hand.length; ++i)
players_hand = new Array();

for (var i = 0; i < num_players * num_cards_each; ++i) {
players_hand[i % num_players] = card_deck;
card_deck.splice(i, 1);
}
}

So the deck has been delt.
Start the game, or the while loop, whichever you prefer to think of it as.

It'll look like this:

var done = false;
// var background = LoadImage("background.png");
var player_index = 0;

// player status values
var OK = 0;
var BUST = 1;

function GetPlayersHandValue(player_index) {
var total_cards = players_hand[player_index].length;
var total_card_value = 0;

for (var i = 0; i < total_cards; ++i)
total_card_value += (players_hand[player_index] + 1) % 12;

return total_card_value;
}

function GetPlayerStatus(player_index) {
var total_cards = players_hand[player_index].length;
if (total_cards > 5)
return BUST;

if (GetPlayersHandValue(player_index) <= 21)
return OK;

return BUST;
}

while (!done) {
var turn_over = false;
while (!turn_over) {
// draw a background
// background.blit(0,0);

// draw the cards
// we skip this step since we don't have images anyway

// give some kind of option
if (player_index == 0) // if it's your turn
{
// menu here, like "stick" or "twist"
}
else
{
// computer A.I. here
}

// check the status
switch(GetPlayerStatus(player_index)) {
case (BUST): turn_over = true; break;
case (OK): break;
}

FlipScreen();
}

// next player
player_index += 1;
if (player_index > num_players)
player_index = 0;

if (player_index == 0) // everyone has had a turn
{
var possible_winners = new Array();
for (var i = 0; i < num_players; ++i)
if (GetPlayerStatus(i) == OK)
possible_winners.push(i);

var winners = new Array();
var highest_value = 0;
for (var i = 0; i < possible_winners.length; ++i)
if (GetPlayersHandValue(possible_winners) > highest_value)
highest_value = GetPlayersHandValue(possible_winners);

for (var i = 0; i < possible_winners.length; ++i)
if (GetPlayersHandValue(possible_winners) == highest_value)
winners.push(possible_winners);

// winners is now an array of the winners

}
}
