I edited the code and then realized that I should not have. I was not able to re-edit it back because you had posted to the thread. Replace lines 17 and 18 with the following:

if (timer == 0) // ... game over routine
}

Is that

if (timer > 0)
{
    timer--;
    if (timer%60 == 0) updateTimerDisplay();
}...

in the act method of the worldclass?

Thanks,When I addes the act method to the worldclass and I compiled it showed me illegal character:"lu00a0". Here is my Code :

import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)

/**
 * Write a description of class level4 here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 */
public class level4 extends World
{
    private int timer;
    private Actor timerDisplay;
    Achtung a = new Achtung();
    Counter counter = new Counter();
    StartGame sg = new StartGame();
    /**
     * Constructor for objects of class level4.
     * 
     */
    public level4()
    {    
        // Create a new world with 600x400 cells with a cell size of 1x1 pixels.
        super(600, 400, 1);
        timer = 1200;
        timerDisplay = new SimpleActor();
        addObject(timerDisplay, 120, 20); // change location as desired
        updateTimerDisplay();
        
        //addObject(new Clock(true, true, 20, "Alert actor after time is up", counter), 450, 60);
        
        {
            addObject(new Achtung(), Greenfoot.getRandomNumber(600), Greenfoot.getRandomNumber(600));
        }
        {
            addObject(a, Greenfoot.getRandomNumber(600), Greenfoot.getRandomNumber(600));
        }
        {
            addObject(new Achtung(), Greenfoot.getRandomNumber(600), Greenfoot.getRandomNumber(600));
        }
        {
            addObject(new Achtung(), Greenfoot.getRandomNumber(600), Greenfoot.getRandomNumber(600));
        }
        {
            addObject(new Achtung(), Greenfoot.getRandomNumber(600), Greenfoot.getRandomNumber(600));
        }
        {
            addObject(new Achtung(), Greenfoot.getRandomNumber(600), Greenfoot.getRandomNumber(600));
        }
        {
            addObject(new Achtung(), Greenfoot.getRandomNumber(600), Greenfoot.getRandomNumber(600));
        }
        {
            addObject(new Schneg(), getWidth()/2, getHeight()/2);
        }
    }
    public void act()
    {
    if (timer > 0)
    { timer--;
         if (timer%60 == 0) { 
         updateTimerDisplay(); }
    }   
    if (timer == 0) // ... game over routine
     {
        
        }
    }
      private void updateTimerDisplay()
    {timerDisplay.setImage(new GreenfootImage("Time remaining: "+(timer/60), 24, Color.BLACK, new Color(0, 0, 0, 0))); // adjust text as desired
    }
    }

It makes sense to show where the error occurs. In this case however, since it is also happening to me, remove the characters and intend it afterwards. Copying code out of the SyntaxHighlighter makes 'space' to this weird character.

You can remove all the curly brackets between lines 31 and 54, inclusive. Also, I do not see a need to keep a reference to a specific Achtung object in the class, so also remove line 13 and change 'a' in line 35 to 'new Achtung()'. I have never come across that particular type of error. Where exactly in the code does it refer you to?

The error is at the start of line 60

Try backspacing line 60 to line 59 then when it moves up to line 59 press <Enter> to move it back to it's correct line.

I don't remember if I came across this exact letter but the error I got was also a bunch of random looking characters. The way I fixed it is shown above.

Thank you now there is no errormessage anymore. But when the time is 0 you win the game . In the game when the Schneh hits the Achtung you lose . I want the clock to stop when the gameover screen is added.

Change line 58 to:

if (timer > 0 && getObjects(GameOver.class).isEmpty())
