@Wavesludge it works :Di ve seen ur code and fix some values .The reason why it did not work is that in ur score class ,try like this values setImage(new GreenfootImage(200, 300)); img.drawString("Score " , 30, 30); Also, set a bigger number for the value in ur world class like this
addObject(thisScore, 155, 150);
