Let us now move on from theory to practice and get down to the actual implementation details. We will begin with implementing the first basic version of
WorldRenderer. Additionally, we will use a utility class for storing constant values in a new class called
Constants. It is true that this class does not appear in the class diagram, as it is just there for our convenience to avoid scattering or, even worse, duplicating certain constants all over the source code files. Also, since the stored values in
Constants are meant to be used in virtually any other class, it would only clutter up the class diagram by drawing one additional line for each class to
For simplicity, we will use the
Constants class for storing our constant values. Alternatively, game constants could be made data driven via a settings file. This would avoid the need to recompile your code when a constant is changed.
