El problema es el siguiente, yo estuve haciendo un programa en java que se intente parecer a la aplicación 2048(juego para smartphone) donde aparece un "tablero" y algunas "fichas", la meta es ir sumando los números que sean iguales hasta llegar a 2048.
El error es que al apretar para algún lado ('a' 's' 'd' o 'w') se mueve en mal, no asía la dirección que debería.
Les dejo el código:
Código PHP:
import java.awt.*;
import javax.swing.*;
import java.util.Random;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
/* Positions[][];
