With the terminal, go to the menubar and select 'Options>Clear' and close out the terminal. Then compile, run and die, report back again.

Sorry my fault. Move the System.out.println statement up one line (to before the 'prepare' call).

#
'false' O_O Wow. Okay. Move it to the first line in the prepare method and try again.

NVM. Move 'this.counter = counter' to before the 'prepare' call in the constructor and remove the System.out.println statement.

private void prepare()
    {
        System.out.println("Counter object is null: "+(counter == null));
        
            
        TryAgain tryagain = new TryAgain();
        addObject(tryagain, 681, 551);
        laughingSkull laughingskull = new laughingSkull();
        addObject(laughingskull, 683, 119);
        
        addObject(counter, 462, 575);
        counter.setLocation(454, 568);
        ;
    }
Not sure if this helps but both the counter, laughingSkull and TryAgain classes do not appear on the world either

Maybe it might be better if you just upload it so I can take a quick look see. Oh, just click on the scenario. (and remove the System.out.println)
