Overview of classes in this program

Controller: Control general gameplay and save/ load function

Game: Manage state a game.

HalfGame: Manage gameplay of a half-move. A half-move is the move of a player in a round.

Pieces: Manage properties of pieces and indicates what moves it can do via #neighbor_generator

Generators: Return a set of valid moves after filtering a initial set of moves

Moves: Represent a move with methods that indicates the effect of that move on game state.

Things that I would like to improve

• The info related to color of each side (like the row/ col of white/ black rook, king, ...) is still scattered all over the code and not concentrated in one place. This results in a lot of duplication.

Chess features that is missing

• En Passant
• Rule related to the number of moves

Background

I learned Ruby from The Odin Project's Ruby in Rail path. And this Chess project is the final project of the Ruby section. It's the capstone project that required me to use all my gained programming knowledge to finish it.

I don't know how long it took others to complete it. For me, I used to decide to quit when I was in a difficult situation and need to apply for a dev job ( and actually got one). I planned to move forward to Rail section. But then I see others in TOP discord, who does the Ruby path like me, can complete it. So I decided to come back and continue this project. But the time to complete this is still very long because I have to do my job too. But I did it: I completed the project!.
