The compiler noticed that you were assigning the variable to itself in several cases, which isn't an outright error but doesn't make sense. In all cases this is happening in the class constructors, where what should be happening is the values passed in as argument assigned to the class fields. Here's the lines from the "Map" class as an example:

      width = width;
      height = height;

Notice that the same name appears on both sides of the assignments. But the field names all start with capital letters, so the name on the left is not correct. The "Point" class has a similar issue. Fix the capitalization of the names and you should be in good shape.

Yep that worked! Didn't notice my caps :O.. Sometimes it's the silly mistakes like that.

Thanks Steven :)
