How to get the arrow keys to work in 2D game?

The best (?) way is to use a KeyListener. http://java.sun.com/j2se/1.4.2/docs/api/java/awt/event/KeyEvent.html

In the class that you want the keyevent to occur, put this in your class declaration implements KeyListener {

Then somewhere in that class, put addkeyListener(this);

. You need to have three methods in this class - keyTyped(KeyEvent e), keyPressed(KeyEvent e) and keyReleased(KeyEvent e).

Here's a sample.

public class Example extends JFrame implements KeyListener

{

//some code goes here...

public void keyTyped (KeyEvent event) {}

public void keyReleased (KeyEvent event) {}

public void keyPressed (KeyEvent event)

{

int key = event.getSource();

if (key == KeyEvent.VK_UP)

{

//etc.

}

}
