Hey so i have been learning greenfoot for a couple months now and we have been given an assessment to come up with our own mini game using what we have learned from the books so far. Myself i am trying to make a small car like game slightly similar to the crab game however it has the player collecting pickups which effect the car with health ammo etc etc. Anyway im having some serious issues trying to get my counter to update i even tried following the youtube video and changing my code that i had to try get it working. 
import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)

        }
    }
    

            
}
This is the coding from my main car class Kit what im want it to do it update the counter when i collect ammo but atm it doesn't work. Any help would be much appreciated i can also link my counter class if required.

I would like to see the code where you create and add your counter object to the world and also where you create your Kit object (basically your world class code).
