Java 2D game - creating menu

**ultimate** · 11-17-2012, 11:47 AM

I am trying to create Menu to my 2D game in Java (Sokoban). But the game is not responding to pressed keyes. Menu is working, but when I choose new game in menu (by pressing Enter), game starts but it does not react to pressed keyes. But, when I remove menu, game is responding to pressed keys ... but when there is also menu, it is not responding. How to solve this problem ?

Here is Sokoban class:

Java Code:

public final class Sokoban extends JFrame  {
    
    private static Menu menu;
    private static Board board;
    private static JFrame myFrame;
    private static Action enterAction;
        
    public Sokoban() {
        InitUI();
    }

    public void InitUI() {
    	
    	myFrame = new JFrame();
    	   	
    	myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        myFrame.setSize(800,600);
        myFrame.setLocationRelativeTo(null);
        myFrame.setTitle("Labyrint");
        myFrame.setResizable(false);
        
        board = new Board();
        menu = new Menu(); 
               
        myFrame.add(menu);
        
        enterAction = new EnterAction();
        
        menu.getInputMap().put( KeyStroke.getKeyStroke( "ENTER" ), "doEnterAction" );
        menu.getActionMap().put( "doEnterAction", enterAction );
        
        myFrame.setVisible(true);
   
        
    }
         
    
    static class EnterAction extends AbstractAction
    {
        public void actionPerformed( ActionEvent tf )
        {
          
            System.out.println( "The Enter key has been pressed." );
            menu.setVisible(false);
			
			menu = null;
			myFrame.add(board);
	        
        } // end method actionPerformed()
        
    } // end class EnterAction
    
    public static void main(String[] args) {
   	    	
        Sokoban sokoban = new Sokoban();
    
    }
}

And this is game, part of Board.class (not responding to pressed keyes when Menu is working) :

Java Code:

public Board() {

           	
    	rightAction = new RightAction();
        
        
        getInputMap().put( KeyStroke.getKeyStroke( "RIGHT" ), "doRightAction" );
        
        
        getActionMap().put( "doRightAction", rightAction );
    	
        
        initWorld();
        
    }
    
    static class RightAction extends AbstractAction
    {
        public void actionPerformed( ActionEvent tf )
        {
          
            System.out.println( "The Right key has been pressed." );
                        
        } 
        
    }

When I delete Menu, it is responding to RIGHT key, but when I add menu, It is not. How to solve this problem ? Help me please. Thank you
