Image Array

[Drackeo]

Hey many of you have helped me with my other project the Black Jack game. This is an extension of that post. Im looking for a way to assign images to each card in a deck. 

 

In the code a deck goes from 0-51. 

0 = Ace of Spades

51 = King of Clubs

 

My images fallow the naming of:  "Suit"_"Rank".png

 

I know i need to do this in a loop as if i was stacking and initializing an array. In fact to create the deck i do just this. 

 

BlackJack

 

package Black_Jack;

 

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.control.Button;

import javafx.scene.control.Label;

import javafx.scene.image.ImageView;

import javafx.scene.layout.BorderPane;

import javafx.scene.layout.HBox;

import javafx.stage.Stage;

 

public class BlackJack extends Application {

 

public void start(Stage primaryStage) throws Exception{

 

Deck deck = new Deck(5);

 

HBox text = new HBox();

Label label1 = new Label("Let's play some black jack!");

text.getChildren().addAll(label1);

 

HBox cards = new HBox(); //this is just how im checking if everything works

        ImageView imgView = new ImageView("cards/Spade_3.png");

        ImageView imgView0 = new ImageView("cards/b1fv.png");

        ImageView imgView1 = new ImageView("cards/b1fv.png");

        ImageView imgView2 = new ImageView("cards/b1fv.png");

        ImageView imgView3 = new ImageView("cards/b1fv.png");

        cards.getChildren().addAll(imgView, imgView0, imgView1, imgView2,imgView3);

 

//HBox hand = new HBox();

 

HBox hb = new HBox(50);

 

Button btn1 = new Button("Shuffle");

Button btn2 = new Button("Deal");

hb.getChildren().addAll(btn1,btn2);

 

BorderPane pane = new BorderPane();

pane.setTop(text);

pane.setCenter(cards);

//pane.setCenter(hand);

pane.setBottom(hb);

 

btn2.setOnAction((clicked) -> {System.out.println("Hit me");});

btn1.setOnAction((clicked) -> {deck.shuffle();});

 

   Scene scene = new Scene(pane, 360, 150);

   primaryStage.setTitle("Card Game"); 

   primaryStage.setScene(scene); 

   primaryStage.show();

}

 

public static void main(String[] args){

Application.launch(args);

}

}

 

 

Deck

 

package Black_Jack;

 

public class Deck {

 

private int[] deck;

private int next_card = 0;

 

public static final int SIZE_OF_DECK = 52;

 

public Deck(){

this(1);

}

 

public Deck(int num_decks){

this.deck  = new int[num_decks*Deck.SIZE_OF_DECK];

System.out.println(num_decks);

for(int i = 0 ; i < this.deck.length; i++){

int k = i%Deck.SIZE_OF_DECK;

this.deck[i] = k;

//System.out.println(this.deck[i]);

} 

}

 

public void shuffle(){

 

for(int i = 0; i<this.deck.length; i++){

int j = (int)(Math.random()*this.deck.length);

int temp = this.deck[i];

this.deck[i] = this.deck[j];

this.deck[j] = temp;

System.out.println(this.deck[i]);

}

 

System.out.println("Shuffled");

this.next_card = 0;

}

 

public Card nextCard(){

return new Card(this.deck[this.next_card++]);

}

 

public boolean hasNext(){

return this.next_card<this.deck.length;

}

}

 

 

Card

 

package Black_Jack;

 

public class Card {

 

private static final String[] suits = {"Club", "Diamond","Heart", "Spade"};

private static final String[] ranks = {"0","1","2","3","4","5","6","7","8","9","10","11", "12"};

private int card;

 

public Card(int c){

             this.card = c;

     }

 

     private String getSuit(){

             return Card.suits[this.card/13];

     }

     

     private String getRank(){

             return Card.ranks[this.card%13];

     }

     

     public int compareTo(Card otherCard) {

             if(this.getSuit() == otherCard.getSuit()){

                 if(otherCard.getRank() == "Ace") return -1;

                     if(this.getRank() == "Ace") return 1;

             }

             if(this.card < otherCard.card) return -1;

             else if (this.card > otherCard.card) return 1;

             else return 0;

     }

     

     @[member=OverRide]

     public String toString(){

             return  this.getRank() + " of " + this.getSuit();

     }

 

}

 

 

Player

 

package Black_Jack;

 

import java.util.Scanner;

import java.util.ArrayList;

 

public class Player {

 

ArrayList<Card> player = new ArrayList<>();

}

You can create a getter for the image in your Card class. It can easily build the file name with the information it stores.

String imageFileName = getSuit() + "_" + getRank() + ".png";

Side note, I would use Enum types for the suit and ranks.

I was also going to make this comment but I wasn't sure if he had a valid reason for using string arrays...

There is, he's using a math trick to calculate the 1-51 number of every card. Enum would be better and clearer, though.

What is an Enum. Hvant learned about them yet
