How do i make a simple memory card game?
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot, and MouseInfo)
/**

public class MemoryGame extends World
{
Card[] cards = new Card[20];
private static Card firstPicked;
private static Card secondPicked;
private int timer;
public static int matchTries;
public static int matchCount;
private int match;
public MemoryGame()
{
super(4, 5, 100);
// load array
// shuffle
// deal
for (int i=0; i<cards.length; i++) cards[i] = new Card("g"+(i/2), i/2);
java.util.Collections.shuffle(java.util.Arrays.asList(cards));
for (int i=0; i<cards.length; i++) addObject(cards[i], i/5, i%5);
}
public void act()
{
if (timer > 0)
{
timer--;
if (timer > 0) return;
match();
}
mouseClicking();
}
private void mouseClicking()
{

I decided to do it this way as I know each image has an id. So I added a int field for the "image id" to the "Card" class, so I can compare the image ids of the 2 currently used ("flipped") cards.
for (int i=0; i<cards.length; i++) cards[i] = new Card("g"+(i/2), i/2);The line for the array.
Just continue with the original codes instead of the new ones.
I'm just stuck on the whole private void match method.

public Card(String fname, int val)
{
value= val;
front = new GreenfootImage(fname+".gif");
setImage(back);
}
I think I would find the value here, fname+".gif");
Although if im looking for the value that would be a int.
