gistlib - create a game of blackjack with betting and promopts in matlab

To create a game of blackjack with betting and prompts in MATLAB, we can follow the steps below:

Set up the basic game interface and rules using the command window:


main.m
clc
clear all

fprintf('Welcome to the game of Blackjack!\n\n')
fprintf('The goal is to draw cards and get as close to 21 as possible without going over. \n')
fprintf('You will start with $100 and can bet any amount you want each round. \n')
fprintf('If you beat the dealer, you win double your bet. If you lose, you lose your bet. \n')
fprintf('If you tie, you push and get your bet back. \n')
fprintf('Face cards are worth 10, Aces are worth 1 or 11, and all other cards are worth their numeric value.\n')

% set up the deck
card = 1:52;
card = mod(card-1, 13)+1;
card(card>10) = 10;
deck = repmat(card, 4, 1);

money = 100;

Create a function to calculate the value of the player's hand:


main.m
function value = hand_value(hand)
% find the number of aces
num_aces = sum(hand == 1);

% calculate the value of the hand
value = sum(hand(hand ~= 1)) + num_aces;

% adjust for aces
if num_aces > 0
    for i = 1:num_aces
        if value + 10 <= 21
            value = value + 10;
        end
    end
end
end

Create a function to deal cards to the player and dealer:


main.m
function [player_hand, dealer_hand, deck] = deal_cards(deck)
% deal player cards
player_hand = deck(randi(length(deck), 1, 2));
deck(ismember(deck, player_hand)) = [];

% deal dealer cards
dealer_hand = deck(randi(length(deck), 1, 2));
deck(ismember(deck, dealer_hand)) = [];

% return the updated deck
end

Create a function for the player's turn, allowing them to hit or stand:


main.m
function [player_hand, deck] = player_turn(player_hand, deck)
fprintf('Your current hand is: \n')
disp(player_hand)

% prompt for hit or stand
hit = input('Would you like to hit or stand? (h/s): ', 's');
while strcmpi(hit, 'h')
    % add another card to the player's hand
    new_card = deck(randi(length(deck)));
    player_hand(end+1) = new_card;
    deck(deck == new_card) = [];
    
    % check if the player busts
    if hand_value(player_hand) > 21
        disp('Bust! You lose this round!')
        return
    end
    
    % display updated hand and prompt again
    fprintf('Your current hand is: \n')
    disp(player_hand)
    hit = input('Would you like to hit or stand? (h/s): ', 's');
end
end

Create a function for the dealer's turn, allowing them to hit or stand:


main.m
function dealer_hand = dealer_turn(dealer_hand, deck)
% dealer hits until they reach 17 or higher
while hand_value(dealer_hand) < 17
    new_card = deck(randi(length(deck)));
    dealer_hand(end+1) = new_card;
    deck(deck == new_card) = [];
end

Put everything together in the main game loop, allowing the player to bet each round:


main.m
while money > 0
    % prompt for the player's bet
    bet = input(sprintf('You have $%d. What would you like to bet? ', money));
    
    % deal the cards
    [player_hand, dealer_hand, deck] = deal_cards(deck);
    
    % give the player their turn
    [player_hand, deck] = player_turn(player_hand, deck);
    
    % if the player busts, they lose their bet
    if hand_value(player_hand) > 21
        money = money - bet;
        fprintf('You lost $%d. Your new balance is $%d.\n', bet, money);
        continue
    end
    
    % give the dealer their turn
    dealer_hand = dealer_turn(dealer_hand, deck);
    
    % determine the winner
    player_value = hand_value(player_hand);
    dealer_value = hand_value(dealer_hand);
    if dealer_value > 21
        money = money + bet;
        fprintf('You won $%d! Your new balance is $%d.\n', bet, money);
    elseif player_value > dealer_value
        money = money + bet;
        fprintf('You won $%d! Your new balance is $%d.\n', bet, money);
    elseif player_value < dealer_value
        money = money - bet;
        fprintf('You lost $%d. Your new balance is $%d.\n', bet, money);
    else
        fprintf('Push! Your new balance is $%d.\n', money);
    end
    
    % check if the player is out of money
    if money <= 0
        fprintf('Game over! You are out of money.\n')
        break
    end
    
    % prompt for another round
    play_again = input('Would you like to play another round? (y/n): ', 's');
    if ~strcmpi(play_again, 'y')
        break
    end
