你有什么建议我保持国王可以走的路?
这可能不会直接回答您的问题,并且您已经标记了正确答案。但只是为了回答上面的问题。
我不会保留国王可以走的所有位置,而是保留允许走的位置并在运行时计算可能的路线。
对于任何棋子(King、Pawn 等),它可以移动 8 个位置。左,右,上,下,左上,右上,左下,右下。根据工件的类型,您可以控制运动。
对于您可以创建一个ChessPiece
类。声明 8 个位置标志,bool
可能是标志,这将定义一个棋子可以移动的可能位置。
声明一块可以跳过的块数,例如方向(; 并从 and 驱动类型ChessPiece
允许。

例如,以下:
//Class that contains the position of the Piece over the Tile
class PiecePosition
{
//Set the bounds an image/vector can move.
public int X, Y;
public PiecePosition(int x, int y) { this.X = x; this.Y = y; }
public PiecePosition(int x, int y, int width, int height) { this.X = x; this.Y = y; }
}
//Base ChessPeice class that shall be used to drive all types of chess pieces.
//Sixteen pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns
//http://en.wikipedia.org/wiki/Chess
abstract class ChessPiece
{
public object Image;//This is an "optional" object that contains the Picture of the Peice,
//alternatively, it may contain vector of the image that you want
//to draw. Right now this is object is here just for the sake of
//understanding that you can use this object here to Draw() it
//based upon its position.
//Possible movements of the unhindered piece=8
protected const int MaxDirectionsCount = 8;
public enum PieceType { King, Pawn, SomeOtherType }//Types of chess peice.
public enum Moves { Up, Down, Left, Right, TopLeft, Etc }//Possible positions a piece can move
protected PieceType Type; //Contains type of piece
protected Moves MoveableDirections;//Shall contain the allowable directions
public List<PiecePosition> listPositions;//List of possible positions to be calculated during runtime
//Defines a piece can skip
protected int SkippableBlocks;
public abstract void PossiblePositions(PiecePosition CurrentPosition);//Calculates possible positions
public abstract void Draw();//Draws the piece
}
//The King Chess piece
//http://en.wikipedia.org/wiki/King_%28chess%29
class King : ChessPiece
{
//Constructor that sets the type of piece
public King()
{
//Set the directions a King can move.
base.MoveableDirections = Moves.Down | Moves.Left | Moves.Right;
base.Type = PieceType.King;
SkippableBlocks = 1; //Max a king can move is one block in the base.Directions set above.
}
//Calculates possible available positions to move to, during runtime; based upon current position.
public override void PossiblePositions(PiecePosition CurrentPosition)
{
//Calculate position
//Since you know this is king piece, you can calculate the possible positions
//And add that the list of possible positions.
//For instance, a King can move
int X = 0; int Y = 0;
for (int i = 0; i < MaxDirectionsCount; i++)
{
//Calculate directions.
if (base.MoveableDirections == Moves.Down) { X = CurrentPosition.X - 1; Y = CurrentPosition.Y; }
if (base.MoveableDirections == Moves.Up) { X = CurrentPosition.X + 1; Y = CurrentPosition.Y; }
//Rest of the directions go here...
//...Btw, what would you do for cross directions?
//One way could be to pass a Rectangle in the ChessTile(x,y,width,height) constructor
//Add to list of possible directions.
listPositions.Add(new PiecePosition(X, Y));
}
}
public override void Draw()
{
//You can actually draw/redraw using the Image object
//based upon the current/moved position.
}
}
顺便说一句,如果您刚刚开始编写代码,我建议您停止。首先四处寻找 Chess 类的设计,看看你是否想从Chess Objects中获得意义。例如,ChessBoard、Game、Players、Piece、Moves、AllowablePositions 等。
查看与 Chess /Google abit 相关的问题,看看问题/答案和您的逻辑是否已经内联。
