I'm in a software engineering class and I want to practice some skills on the most basic case possible : tic tac toe. I know this is overkill but I want to do it in "proper" OOP.
I designed a class diagram for it but there is one point where I don't clearly see what would be the best design decision.
("Joueur" means "Player", "PlancheDeJeu" means "Game board")
Given this diagram, according to the
Low coupling and
Strong cohesion design patterns (sorry if those are not the correct english terms, I am translating) the score should be kept by the user class (Joueur). However, since there is no direct relation between Joueur and Système I don't exactly know how the game could display the score in a clean way. In this diagram, Système would have to ask the PlancheDeJeu object about the score and it would itself have to get it from Joueur. This seems wrong. I am trying to think of how to design an intermediary object that would link Joueur and Système but I can't come up with a good idea.
What would be the best way to go here ?
