import javax.swing.*; import java.awt.*; import java.awt.event.*; import javax.swing.JFrame;

public class DirectionPanel extends JPanel { public static void main (String[] args) {

JFrame frame = new JFrame ("Direction"); frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); frame.getContentPane().add (new DirectionPanel()); frame.pack(); frame.setVisible(true); } private final int WIDTH = 300, HEIGHT = 200; private final int JUMP = 10; // increment for image movement

private final int IMAGE_SIZE = 31;

private ImageIcon up, down, right, left, currentImage; private int x, y;

//----------------------------------------------------------------- // Constructor: Sets up this panel and loads the images. //----------------------------------------------------------------- public DirectionPanel() { addKeyListener (new DirectionListener());

x = WIDTH / 2; y = HEIGHT / 2;

up = new ImageIcon("arrowUp.gif"); down = new ImageIcon("arrowDown.gif"); left = new ImageIcon("arrowLeft.gif"); right = new ImageIcon("arrowRight.gif");

currentImage = right;

setBackground(Color.black); setPreferredSize(new Dimension(WIDTH, HEIGHT)); setFocusable(true); }

//----------------------------------------------------------------- // Draws the image in the current location. //----------------------------------------------------------------- public void paintComponent(Graphics page) { super.paintComponent(page); currentImage.paintIcon(this, page, x, y); }
