In C++, Im trying to make a game board out of a 2d array of Tile objects, A class I made. It looks something like this:

I’m drawing a complete blank on what to actually call what I want to do (hence the difficulty I am having in trying to research it). But what I do have is this:

I have the following architecture
#include

class Base { int m_var; public: virtual void mf_0() = 0; //The contract. The compulsory Customization virtual void mf_1(); //The customizable “default behaviour” int m_f2(); // the invariant. Redefining this in derived class would mean // the derived class is-not-really-a base class .. or that this // non virtual function should really be virtual, i.e. […]

I have following architecture

Let’s say I have a base class “base” and three classes that inherit it “A”, “B”, and “C”. Class A needs access to method1, and method2. Class b needs access to method2, and method3. Class c needs access to method3 and method4. Should all of these methods be defined in the base Class? It seems wrong for each derived class to have access to methods that they do not need. Is there a better solution that I’m not thinking of?
