Write a method in the counter class which updates the integer and displays the updated value. The counter class should be a subclass of actor so that you can put it in the world. Maintain a reference to the counter from the world, and have the bullet fetch the counter reference from the world whenever it hits a bot, and call the update method. The easiest way to have the counter display a value is to use the GreenfootImage constructor which takes a string argument (and two Color arguments) and set the actor image to the resulting GreenfootImage.
