Object Oriented Design for a Chess game [closed]

Answer 1

Here is my idea, for a fairly basic chess game :

class GameBoard {
 IPiece config[8][8];  

 init {
  createAndPlacePieces("Black");
  createAndPlacePieces("White");
  setTurn("Black");

 }

 createAndPlacePieces(color) {
   //generate pieces using a factory method
   //for e.g. config[1][0] = PieceFactory("Pawn",color);
 }

 setTurn(color) {
   turn = color;
 }

 move(fromPt,toPt) {
  if(getPcAt(fromPt).color == turn) {
    toPtHasOppositeColorPiece = getPcAt(toPt) != null && getPcAt(toPt).color != turn;
    possiblePath = getPcAt(fromPt).generatePossiblePath(fromPt,toPt,toPtHasOppositeColorPiece);
   if(possiblePath != NULL) {
      traversePath();
      changeTurn();
   }
  }
 } 

}

Interface IPiece {
  function generatePossiblePath(fromPt,toPt,toPtHasEnemy);
}

class PawnPiece implements IPiece{
  function generatePossiblePath(fromPt,toPt,toPtHasEnemy) {
    return an array of points if such a path is possible
    else return null;
  }
}

class ElephantPiece implements IPiece {....}
