It’s a question that a lot of people find themselves wondering, especially as they’re just starting to learn the game. The IBoard interface is there just to show the point. Return board.GetPieceColor(toX, toY) = bishopColor There's a piece here: the move is valid only if we can capture If (board.IsEmpty(toX, toY)) return true // No piece: move is valid If(board.IsEmpty(x, y)) continue // No obstacles here: keep goingĮlse return false // Obstacle found before reaching target: the move is invalid Also validate if the coordinates are in the 0-7 range If (pathLength != Mathf.Abs(toY - fromY)) return false // Not diagonal public enum PieceColor īool BishopCanMove(PieceColor bishopColor, int fromX, int fromY, int toX, int toY) I think the common way to do it would be checking if each cell on the path is empty or not. ![]() You need to take the board state into account for that.
