    Question How to get keys pressed by the user to control the unit in a game.

    I am making a game and i want it to work like this:

    1): the users presses a key and gets a player asigned to him/her.
    2): The user can use the arrow keys or w/s/d/a to control the unit.
    3): The space bar key is pressed and a shot is fired.

    and allot more things.

    i have this code (just a simple code, not yet my game code) that just starts about getting key from the user.

    import java.awt.event.*; 
    import javax.swing.*; 
     
    public class KeyStrokeTest { 
        public static void main(String[] args) { 
            JPanel panel = new JPanel(); 
     
            /* add a new action named "foo" to the panel's action map */ 
            panel.getActionMap().put("foo", new AbstractAction() { 
                    public void actionPerformed(ActionEvent e) { 
                        if(e == KeyStroke.getKeyStroke(Character.valueOf('a')))
                        {
                            System.out.println(e);
                        }
                    } 
                }); 
     
            /* connect two keystrokes with the newly created "foo" action: 
               - a 
               - CTRL-a 
            */ 
            InputMap inputMap = panel.getInputMap(); 
            inputMap.put(KeyStroke.getKeyStroke(Character.valueOf('a'), 0), "foo"); 
            inputMap.put(KeyStroke.getKeyStroke(Character.valueOf('a'), InputEvent.CTRL_DOWN_MASK), "foo"); 
     
            /* display the panel in a frame */ 
            JFrame frame = new JFrame(); 
            frame.getContentPane().add(panel); 
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
            frame.setSize(400, 400); 
            frame.setVisible(true); 
        } 
    }

    when the a key is pressed it displays a message, now how do i make a deferint message, action ect. for each other key?

    Thanks...
