Create a HighScore class. Make use of the UserInfo class and the storage provided by it.

             myInfo.store();  // write back to server
         }
     }
But I am very new at coding and need help on what to do.

You will use something quite similar. I suggest making use of (by overriding) the addedToWorld method so you can easily remove the actor if storage is not available or the user is not logged in. In current, or some recent, versions of greenfoot, myInfo should be checked for a null value before proceeding with line 3.

Oops ... sorry. Before line 5, insert:

int count = Counter.score;

Add parenthesis after getScore (like in line 10).

You don't. Just create an instance and add it to the world. Greenfoot will call it.

Before I used

Counter counter = new Counter();

new Counter() creates a Counter instance. new HighScore() will create a HighScore instance. Use:
?
1
addObject(new HighScore(), ???, ???);
or
?
1
2
HighScore highScore = new HighScore();
addObject(highScore, ???, ???);
