Ok ... my logics is rather simple, I just wanted to a simple flipper. Just want to see it change from it initial state to a flip state. I'm using a polygon for it initial state and a rectangle when the keyPressed method is invoked. However, whenever I pressed the key, nothing happens. Pls help.
Below is my code,
public void keyPressed(KeyEvent evt) {
       char ch = evt.getKeyChar();
       // Move the left flipper.
       if(ch == 122){
        //leftflip = new LeftFlipper(true);
         setStatus(true);
          System.out.println(stat);
            update(getGraphics());
       else if (ch == 109){ 
        // Move the right flipper.
       // rightflip = new RightFlipper(true);
        setStatus(true);
         System.out.println(stat);
          update(getGraphics());              
       else{
            setStatus(false);
             System.out.println(stat);
               update(getGraphics());
       Part of my flipper class,
public void paint (Graphics g)
        g.setColor(Color.red);
        p = new PinBallGame();
       state1= p.getStatus();
        if(state1 == true){
          g.fillRect(hit1.x, hit1.y, hit1.width, hit1.height);
          System.out.println("In R fillRect");
          state1=false;
        else{
          g.fillPolygon(rflipper);
    }Pls advice me what should i do to see the flipper move.
