Any idea why my "You Lost" screen is not working? In MyWorld class: 
public void act()
    {
        this.showText("Punkte: " + DonkeyKong.score, 50, 10);
        this.lost();
    }
    
    public void lost()
    {
        YouLost youlost = new YouLost();
        if (!getObjects(DonkeyKong.class).isEmpty())
        {
            this.addObject(youlost, this.getWidth()/2, this.getHeight()/2);          
        }
    }
You
public void act() 
    {
        setImage(new GreenfootImage("You Lost!!! ", 60, Color.WHITE, Color.BLACK));
    }
Lost Class:

And if someone wants to solve this too: I have a Boss.class and a DkBoss.class I want the boss to die if he has 0 lives. This is my Code:
public void act() 
    {
        move(4);
        this.touchingBoss();
    }    
    
    public void touchingBoss()
    {
       Actor boss = getOneIntersectingObject(Boss.class);
       if (boss != null) {
       if(this.isTouching(Boss.class) && Boss.lives > 0) {    
           Boss.lives = Boss.lives -1;
           getWorld().removeObject(this);
       }
       }    
       else if(this.atWorldEdge())
       {
            this.getWorld().removeObject(this);
       } 
       
       if (Boss.lives == 0)
       {
           getWorld().removeObject(boss);
       }
    }

Define "not working". What is happening, what should happen?

For the boss thing, don't make 'lives' static. Use 'boss' (the object) instead of 'Boss' (the class) when accessing the 'lives' variable. Check if the variable is 0 right after decreasing it.

If i DonkeyKong.class dies it should show: "You Lost!!!" But "You Lost!!!" shows all the time and it starts lagging.

I didn't understand what you wanted me to do. Well if the bullet hits him, he loses 1 life, and if he gets 0 lives the game doesn't work.

It shows a "NullPointerException" If i run the game again and hit him one more time, he dies, java.lang.NullPointerException at DkBoss.touchingBoss(DkBoss.java:37) at DkBoss.act(DkBoss.java:18)

Change line 10 to: 
if (getObjects(DonkeyKong.class).isEmpty() && getObjects(YouLost.class).isEmpty())
You only want to create and add a YouLost object when the player is not in the world AND a YouLost object has not been added yet.

For the moment. I am getting ready to depart for a while. Line 6 of what Hippo supplied should be: 
((Boss)boss).loseLife(1);
There are more replies on the next page.
