Problem med diagram, Slick/JLWGL

Hej allesammen! Jeg har et problem med Slick og JLWGL. Ved ikke om nogen af jer har arbejdet med biblioteket f�r, men har problem i f�lgende kode:

Java kode

 //    JUMP
        else if(input.isKeyDown(Input.KEY_W))
        {
            do
            {
               if(ballPosY < defBallPosY + 10)
               {
                   ballPosY -= delta * .1f;
               }
               else
               {
                   ballPosY += delta * .1f;
               }
            }
            while(ballPosY != defBallPosY);
            
            ballPosY = defBallPosY; // Sætter default BalPosY
        }

Hvis jeg k�rer programmet og trykker W svarer programmet ikke... Hvilket jeg ikke helt forst�r.

Her er resten af koden:

Game klassen

Java kode

 package javagame;
 
 import org.newdawn.slick.*;
 import org.newdawn.slick.state.*;
 
 public class Game extends StateBasedGame
 {
    
    public static final String gamename = "Mini Game";
    public static final int menu = 0;
    public static final int play = 1;
    
    public Game(String gamename)
    {
       super(gamename);
       this.addState(new Menu(menu));
       this.addState(new Play(play));
    }
    
    public void initStatesList(GameContainer gc) throws SlickException
    {
       this.getState(menu).init(gc, this);
       this.getState(play).init(gc, this);
       this.enterState(menu);
    }
    
    public static void main(String[] args) 
    {
       AppGameContainer appgc;
       try
       {
          appgc = new AppGameContainer(new Game(gamename));
          appgc.setDisplayMode(600, 400, false);
          appgc.start();
       }
       catch(SlickException e)
       {
          e.printStackTrace();
       }
    }
 
 }

Menu klassen:

Java kode

 package javagame;
 
 import org.newdawn.slick.*;
 import org.newdawn.slick.state.*;
 
 public class Menu extends BasicGameState
 {
    Image ball, ballSqueezed, map;
    Animation roll, squeeze, purpBall;
    
    int[] duration = {200,200};
    int defBallPosX = 0; // DEFAULT
    int defBallPosY = 175; // DEFAULT
    int ballPosX = 0; 
    int ballPosY = 175; 
    
    public Menu(int state)
    {
        
    }
    
    public void init(GameContainer gc, StateBasedGame sbg) throws SlickException
    {
        map = new Image("res/WorldMap.png");     
        ball = new Image("res/PurpBallNorm.png");                 // X: 24px         Y: 25px    
        ballSqueezed = new Image("res/PurpBallSqueezed.png");     // X: 8px         Y: 25px 
        
        Image[] rollPics = {ball, ball};
        roll = new Animation(rollPics, duration, false);
 
        Image[] squeezePics = {ballSqueezed, ballSqueezed}; 
        squeeze = new Animation(squeezePics, duration, false);
        
        purpBall = roll;
    }
    
    public void render(GameContainer gc, StateBasedGame sbg, Graphics g) throws SlickException
    {
        map.draw();
        
        g.setColor(Color.black);
        g.drawLine(0, 200, 600, 200);
        g.drawLine(100, 200, 100, 180);
        g.drawLine(150, 200, 150, 180);
        g.drawLine(225, 200, 225, 180);
        g.drawLine(275, 180, 275, 160);
        g.drawLine(350, 180, 350, 160);
        g.drawLine(400, 200, 400, 180);
        g.drawLine(450, 200, 450, 180);
        g.drawLine(500, 180, 500, 160);
        g.drawLine(550, 200, 550, 180);
        
        purpBall.draw(ballPosX, ballPosY);
    }
    
    public void update(GameContainer gc, StateBasedGame sbg, int delta) throws SlickException
    {
        Input input = gc.getInput();
        
        //    FORWARD
        if(input.isKeyDown(Input.KEY_D))
        {
            ballPosX += delta *.1f;
        }
        //    BACKWARD
        else if(input.isKeyDown(Input.KEY_A))
        {
            ballPosX -= delta * .1f;
        }
        //    JUMP
        else if(input.isKeyDown(Input.KEY_W))
        {
            do
            {
               if(ballPosY < defBallPosY + 10)
               {
                   ballPosY -= delta * .1f;
               }
               else

            while(ballPosY != defBallPosY);
