Adapting classes to use lights

Obviously, each and every single class that does any rendering in our game does it differently. Rendering the same graphics to different types of material maps is no exception to this rule. Let's see how every light-supporting class should implement their respective Draw methods in order to stay in sync with our lighting system.

The Map class

The first class we need to deal with is the Map class. It will be a bit different due to the way it handles the drawing of tiles. So let's take a look at what needs to be added in:

class Map : ..., public LightUser { 
public: 
  ... 
  void Draw(MaterialMapContainer& l_materials, 
    Window& l_window, int l_layer); 
protected: 
  ... 
  Void CheckTextureSizes(int l_fromZ, int l_toZ); 
  std::array<sf::RenderTexture, Sheet::Num_Layers> m_textures; 
  ... 
}; 

So far, so good! The Map class is now using the LightUser interface. The m_textures data member is an established array that existed before all of this...
