在国际象棋比赛中获得国王的位置

发布于 2024-10-06 15:58:19 字数 775 浏览 10 评论 0原文

我正在写一个简单的国际象棋游戏，有 3 个棋子，一侧有一个国王和一个王后，另一侧只有一个国王，国王和王后应该用较少的动作来交配单独的国王。在这个项目中，首先我们应该从用户然后据此做其他工作，我想知道如何从用户那里得到国王应该呆在哪个地方？我实现了带有 64 个图片框的表单。我将为位置编写类，非常感谢

编辑：

我从 Jon Skeet 先生的回答中写了这段代码：它有什么错误？因为当我点击时它没有做任何事情，谢谢

PictureBox[,] pic = new PictureBox[8, 8];

public PictureBox SetKingImage(int x,int y)
    {


        pic[x,y].Image=Image.FromFile("pic/siyahsah2.JPG");
        return pic[x, y];
    }

public void GetClickedPicturebox()
    {  
        int x, y;

      for(x=0;x<8;x++)
      {
          for(y=0;y<8;y++)
          {
              pic[x, y] = new PictureBox();

              pic[x, y].Click += (object sender, System.EventArgs e) =>SetKingImage(x, y);


            }
          }
      }

i m writing a simple chess game that has 3pieces,a king and a queen one side and other side just a king,the king and queen should mate alone king with less movements.in this project,first we should get the place of alone king from user and then according to that do other works,i want to know how can i get from user that in which place should king stay?i implemented form with 64 pictureboxes.i will write class for positions,thanks so much

i wrote this code from Mr Jon Skeet answer:
what mistake does it have?because it doesnt do anything when i click,thanks

PictureBox[,] pic = new PictureBox[8, 8];

public PictureBox SetKingImage(int x,int y)
    {


        pic[x,y].Image=Image.FromFile("pic/siyahsah2.JPG");
        return pic[x, y];
    }

public void GetClickedPicturebox()
    {  
        int x, y;

      for(x=0;x<8;x++)
      {
          for(y=0;y<8;y++)
          {
              pic[x, y] = new PictureBox();

              pic[x, y].Click += (object sender, System.EventArgs e) =>SetKingImage(x, y);


            }
          }
      }

最简单的方法是要求用户单击相关的图片框。您可以通过以下三种方式之一确定哪个 PictureBox 被单击：

对每个 PictureBox 使用相同的事件处理程序进行订阅，但使用 PictureBox 中的标签来获取坐标
对每个 PictureBox 使用相同的事件处理程序进行订阅，但仅使用引用到 PictureBox（sender）来查找它是哪一个并适当地获取坐标

使用封装位置的 lambda 表达式进行订阅，如下所示：

for (int x = 0; x < 8; x++) {
    for (int y = 0; y < 8; y++) {
        pictureBoxes[x, y].Click += (sender, args) =>设置KingPosition(x, y);
    }
}

后一种方法的一个问题是通过 lambda 表达式取消订阅事件相对痛苦 - 并且您可能想要取消订阅 单击第一个按钮时的所有事件处理程序。

另一种方法是将事件处理程序保留在适当的位置，并在时机不对时忽略它们:)

The simplest approach would be to ask the user to click on the relevant picture box. You could determine which PictureBox was clicked on in one of three ways:

Subscribe using the same event handler for each PictureBox, but use a Tag within the PictureBox to get the coordinates
Subscribe using the same event handler for each PictureBox, but just use the reference to the PictureBox (sender) to find which one it was and get the coordinates appropriately

Subscribe using a lambda expression which encapsulates the position, like this:

for (int x = 0; x < 8; x++) {
    for (int y = 0; y < 8; y++) {
        pictureBoxes[x, y].Click += (sender, args) => SetKingPosition(x, y);
    }
}

One problem with the latter approach is that unsubscribing from an event via a lambda expression is relatively painful - and you probably want to unsubscribe all the event handlers when the first button is clicked.

An alternative is to leave the event handlers in place, and ignore them when it's not the right time :)
