martijn, the method is telling you that there is no "gameOver()" method, which is clearly the case. You are trying to call a method which doesn't exist. You could solve the problem by writing a gameOver method - which does whatever you want it to do - or by removing the line which calls the non-existent method.

But is this what you mean public voit gameOver() { gameOver();} what you mean

#

You could start with:

public void gameOver()
{

}

... yes. But you can't put "gameOver()" inside it, as it's then just calling itself. You need to put the right Java code inside the method, to do whatever it is that you want the method to do. Note that it's "void" and not "voit".

On line 17, you have an if statement, but no commands to execute if true.

What do you want the scenario to do after the 60 seconds is up?

#

that it go to the hiscore (and you can go to hiscore if you are gameover)

#

You already wrote the code for GameOver()? Is it in a different class (which class is it in)?

I have just wrote this

public void gameOver() 

    { saver.saveHighscore(counter.getValue());  
      removeObject(user);  
      board = new ScoreBoard(600, 600);  
      addObject(board, getWidth() /2, getHeight() /2);
      Greenfoot.stop();
     
    }
