  • 摘要:本文是利用C#实现中国象棋的棋盘绘制,以及初始化布局,并不实现中国象棋的对弈逻辑。仅供学习参考使用。思路:绘制中国象棋棋盘,竖线九条,横线十条。再中间绘制‘楚河’,‘汉界’。绘制棋子,然后将棋子布局在棋盘上即可。涉及知识点:用户控件:用于实现棋盘的绘制,重写OnPaint(PaintEventArgse)方法。Matrix:封装表示几何变换的3x3仿射矩阵。本例中主要用于旋转绘制反方的‘汉界’。GraphicsPath:表示一系列相互连接的直线和曲线。本例中主要用于绘制圆形棋子。效果图如下:

本文是利用C# 实现中国象棋的棋盘绘制,以及初始化布局,并不实现中国象棋的对弈逻辑。仅供学习参考使用。

思路:

  1. 绘制中国象棋棋盘,竖线九条,横线十条。再中间绘制‘楚河’,‘汉界’ 。
  2. 绘制棋子,然后将棋子布局在棋盘上即可。

涉及知识点:

  1. 用户控件:用于实现棋盘的绘制,重写 OnPaint(PaintEventArgs e) 方法。
  2. Matrix:封装表示几何变换的 3x3 仿射矩阵。本例中主要用于旋转绘制反方的‘汉界’。
  3. GraphicsPath:表示一系列相互连接的直线和曲线。本例中主要用于绘制圆形棋子。

效果图如下:(一)

核心代码

棋盘核心代码如下:
