棋桌上的骑士运动 [英] Knight movement in chess table

问题描述

大家好，
我正在做练习，只是骑士在棋盘上的动作...
我使用嵌套的for循环和我的按钮名为btn [x，y]的按钮填充了flowLayoutPanel ....我可以将pictureBox1.Image从按钮上的外部拖动...骑士必须像国际象棋游戏一样移动(当我拖曳btn图像时，我可以看到红色按钮BackColors按规则显示，但我不能按照规则移动骑士. .
我该怎么办?

Hello to everybody,
I am doing an exercise with about just knight''s movement on chess table...
I filled in flowLayoutPanel with button using nested for loop and my button''s named btn[x,y]....I can drag pictureBox1.Image from outside on buttons...the knight must be moved as chess game( the L shaped)....when I dragdrop btn.Image I can see Red button BackColors according to the rules but I can''t move the knight according to the rules.Where I am doing mistakes ?I felt tired to think about it.
How do I do this ?

private void btn_MouseDown(object sender, MouseEventArgs e)
{   // Here I keep knight .
    Button button = sender as Button; 
    int[] array1 = (int[])button.Tag;
    int x = array1[0];
    int y = array1[1];
    if (e.Button == MouseButtons.Left && button.Image != null)
    {
        button.DoDragDrop(button.Image, DragDropEffects.Move);
    }
}
void btn_DragEnter(object sender, DragEventArgs e)
{// Here knight is moving
    Button button = (Button)sender;
    e.Effect = DragDropEffects.All;
    int[] array1 = (int[])button.Tag;
    int x = array1[0];
    int y = array1[1];
    //button.Image = null;
}


void btn_DragDrop(object sender, DragEventArgs e)
{ // ANd Here it must be implement the rules.When I left mouse left click button I can see the red BackColor as accordance with the rules.but my knight is going everywhere in chess table .İt shouldn't be like this 
    Button button = (Button)sender;
    button.Image = (Bitmap)e.Data.GetData(DataFormats.Bitmap);
    int[] array1 = (int[])button.Tag;
    int x = array1[0];
    int y = array1[1];

       if ((x + 1 >= 0 && y + 2 <= 7) && (y + 2 >= 0 && x + 1 <= 7))
        {
            btn[x + 1, y + 2].BackColor = Color.Red;                    
        }
        if ((x + 1 >= 0 && y - 2 <= 7) && (y - 2 >= 0 && x + 1 <= 7))
        {
            btn[x + 1, y - 2].BackColor = Color.Red;
        }
        if ((x - 1 >= 0 && y + 2 <= 7) && (y + 2 >= 0 && x - 1 <= 7))
        {
            btn[x - 1, y + 2].BackColor = Color.Red;
        }
        if ((x - 1 >= 0 && y - 2 <= 7) && (y - 2 >= 0 && x - 1 <= 7))
        {
            btn[x - 1, y - 2].BackColor = Color.Red;
        }
        if ((x + 2 >= 0 && y + 1 <= 7) && (y + 1 >= 0 && x + 2 <= 7))
        {
            btn[x + 2, y + 1].BackColor = Color.Red;
        }
        if ((x + 2 >= 0 && y - 1 <= 7) && (y - 1 >= 0 && x + 2 <= 7))
        {
            btn[x + 2, y - 1].BackColor = Color.Red;
        }
        if ((x - 2 >= 0 && y + 1 <= 7) && (y + 1 >= 0 && x - 2 <= 7))
        {
            btn[x - 2, y + 1].BackColor = Color.Red;
        }
        if ((x - 2 >= 0 && y - 1 <= 7) && (y - 1 >= 0 && x - 2 <= 7))
        {
            btn[x - 2, y - 1].BackColor = Color.Red;
        }

    btn[x , y].DoDragDrop(pictureBox1.Image, DragDropEffects.All);
}

你好
请遵循以下算法:

1.保留骑士的x和y
2.移动骑士
3.保留New x和y(newX和New Y)
4. isCorrect = false
5.如果newX和newY已被占用，那么Knight将移回x，y并结束
6.如果newX-1 = x并且newY-2 = y，则isCorrect = true;
7.如果newX-1 = x并且newY + 2 = y，则isCorrect = true;
8.如果newX +1 = x并且newY-2 = y，则isCorrect = true;
9.如果newX +1 = x并且newY + 2 = y，则isCorrect = true;
10.如果isCorrect = false，则Knight将移回x，y
11.结束

Hello
Follow this algorithm:

1. Keep x and y of knight
2. Move the Knight
3. Keep New x and y (newX and New Y)
4. isCorrect = false
5. If newX and newY has occupied then Knight will Move back to x,y and end
6. IfnewX - 1 = x And newY - 2 = y then isCorrect = true;
7. If newX - 1 = x And newY + 2 = y then isCorrect = true;
8. If newX + 1 = x And newY - 2 = y then isCorrect = true;
9. If newX + 1 = x And newY + 2 = y then isCorrect = true;
10. If isCorrect = false then Knight will Move back to x,y
11. end

您在btn_DragDrop()中分配

button.Image = (Bitmap)e.Data.GetData(DataFormats.Bitmap);

没有任何测试，是否允许骑士移动到这里.我认为，如果您在btn_DragEnter中进行了这样的测试，那将是可以的.然后可以设置DragEventArgs.DragDropEffects = None，这将阻止调用btn_DragDrop().

其次，AFAIR，对DoDragDrop()的调用不属于您的btn_DragDrop()方法.您可以在btn_MouseDown()中正确使用它来开始拖动操作.

in btn_DragDrop() without any test whether the knight is allowed to move here or not. I think that would be OK, if you had such a test in btn_DragEnter. You could then set DragEventArgs.DragDropEffects = None which would prevent btn_DragDrop() from being called.

Second, AFAIR, the call to DoDragDrop() doesn''t belong in your btn_DragDrop() method. It''s for starting the drag operation as you use it correctly in btn_MouseDown().
