Are you calling 'addLevel' from anywhere? (like the 'act' method of the class)

There are two things at this point which may be of concern. The first one is line 3 in the 'addLevel' method which will always be true (any integer value divided by one will have no remainder). The other one is line 7 of the same method which places the new asteroid at a y location of between '-680' and 'getHeight()-679' (mostly off the left edge of the world or at the left edge if your world is bounded by using 'super(int, int, int)' or 'super(int, int, int, true)' to create the world).

There is something amiss in your 'atWorldEdge' method. The last two conditions are not coded similarly.

Remove the division sign, "/", in the middle of line 6 of the 'atWorldEdge' method (in the 'return' statement).
