help please

If you only want the score to be increased if an enemy is hit, then you should put the related code to the position when it checked if there is an enemy. By the way, why do you use 3 lines of code to remove one object? You can just use 'getWorld().removeObject(...)'.

How do you do that?

You are already have the conditions to check if there is an enemy (line 37 and line 46). In this if-blocks, you need to call the 'addScore' method on the Counter object. (the part you commented out has to go there)
