编写网络象棋案例————Silverlight（棋子篇）

在上一节我们讲解了棋盘的制作，在这一节我们来讲解一下关于棋子的制作，首先我们要知道制作棋子有2种方法（个人见解，学疏才浅）

1、自己画图：用Ellipse类（使用方法请参照Silverlight 3.0文档）

2、加载图片的方式

一般用 IMAGE中的URI进行加载，定位好坐标即可。

在这里体现我们的动手能力，就使用第一种吧（有特别需要的可以发帖，我有第二种方法）

说了那么多废话，现在开始

问：制作棋子需要什么信息呢？

答：当然是棋子名，颜色，坐标，棋子大小，棋子起始坐标，移动坐标

好了又了这些需求我们开始编写程序：

using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;

using System.Windows.Shapes;

        {
            chessman_dangqianzuobiao = new Point(x, y);
            chessman_move = chessman_dangqianzuobiao;
            chessman_radius = raduis;
            chessman_color = color;
            chessman_name = name;
        }
        private void Draw()
        {
            //圆的制作
            Ellipse ell = new Ellipse()
            {
                Width=chessman_radius*2,
                Height=chessman_radius*2,
                Stroke=new SolidColorBrush(chessman_color),
                Fill=new SolidColorBrush(chessman_color),
                Opacity=15
            };
            //圆中的内容
            TextBlock chessman_text = new TextBlock()
            {
                TextAlignment=TextAlignment.Center,
                FontFamily=new FontFamily("宋体"),
                FontSize=chessman_radius,
                FontWeight=FontWeights.Bold,
                Foreground=new SolidColorBrush(Colors.Green),
                Text=chessman_name,
                Margin=new Thickness(chessman_radius/2-1,chessman_radius/2-1,0,0),

            };
            chessman_qizi = new Canvas();
            chessman_qizi.Children.Add(ell);
            chessman_qizi.Children.Add(chessman_text);
            qizi1.Children.Add(chessman_qizi);
         
        }
        public void DrawIn(Panel qizi2)
        {
            qizi1 = qizi2;
            Draw();
        }
    }

}
