纸牌游戏有很多种玩法,C#代码写的纸牌游戏,网上也能找到不少,从中也能学习到不少知识,自己动手也写一个,算是记录下学习过程吧.
纸牌21点的玩法也比较简单,就是看谁手中的所有牌相加是21点,或是离21点的数字最近,最大者赢.照着这样思路开始编写代码.
牌面A到10按牌面数字算点数,J,Q,K,大小王都算10点;
定义一个纸牌父类PKFather
public enum PokerColour
{ Diamond,//方块=0
Club, //梅花=1
Heart, //红桃=2
Spade, //黑桃=3
Wang,
}
public enum Rank //牌面点数
{
One = ,
Two,
Three,
Four,
Five,
Six,
Seven,
Eight,
Nine,
Ten,
Jack,
Queen,
King,
XWang,
DWang,
}
public abstract class PKFather
{
public int X { get; set; }
public int Y { get; set; }
public int Width { get; set; }
public int Height { get; set; }
public Rank Rank { get; set; }//牌面点数
public PokerColour PkColour { get; set; }//牌面花色；红桃，黑桃，方片，梅花； public PKFather(int x,int y,int width,int height,Rank rank,PokerColour pkColour)
{
this.X = x;
this.Y = y;
this.Width = width;
this.Height = height;
this.Rank = rank;
this.PkColour = pkColour; }
public abstract void Draw(Graphics g);
}
父类中定义了两个枚举,Rank用做牌面点数,PokerColour用做牌的花色,其实牌的花色在21点这个小游戏中用不上,只是在剪裁纸牌图片时需要.纸牌的图片如下:
整 个一副牌都在一个图片中，这两个枚举值等于提供了行列坐标，剪裁图片时更方便些,用法在后面的代码中，抽象方法Draw在子类中实现。
class RPoker:PKFather
{
Image image = Resources.card;//图片在资源文件中
public RPoker(int x, int y, int width, int height, Rank rank, PokerColour pkcolour)
: base(x, y, width, height, rank,pkcolour)
{ } public override void Draw(System.Drawing.Graphics g)
{
Rectangle rect = new Rectangle(this.X, this.Y, Width, Height);//要裁切图片的位置大小
switch (this.PkColour)
{
case PokerColour.Diamond:
g.DrawImage(image, rect, new Rectangle(((int)Rank - ) * Width, (int)(PkColour + ) * Height, Width, Height), GraphicsUnit.Pixel);
break;
case PokerColour.Club:
g.DrawImage(image, rect, new Rectangle(((int)Rank - ) * Width, (int)(PkColour + ) * Height, Width, Height), GraphicsUnit.Pixel);
break;
case PokerColour.Heart:
g.DrawImage(image, rect, new Rectangle(((int)Rank - ) * Width, (int)(PkColour - ) * Height, Width, Height), GraphicsUnit.Pixel);
break;
case PokerColour.Spade:
g.DrawImage(image, rect, new Rectangle(((int)Rank - ) * Width, (int)(PkColour - ) * Height, Width, Height), GraphicsUnit.Pixel);
break;
case PokerColour.Wang:
g.DrawImage(image, rect, new Rectangle(((int)Rank - ) * Width, (int)PkColour * Height, Width, Height), GraphicsUnit.Pixel);
break;
default:
break;
} }
}
子类RPoker继承自PKFather，实现抽象方法Draw，用来绘制具体的纸牌。将纸牌的图片加入项目的资源文件步骤是，在解决方案资源管理器中，选中项目，依次点开 Properties->Resources.resx （双击该文件）->在打开的窗口中选菜单"添加资源"->添加现有文件；选中要加入的图片，点确定就成了。更简便的方法是当双击Resources.resx文件在vs中打开后，直接拖入图片，就可完成添加图片的步骤。Image image = Resources.card;将图片资源赋值给image，这样在后面的代码中，就可以对image中的纸牌图片进行剪裁，提取了。
生成54张牌
private void GetCard()
{
for (int j = ; j <= ; j++)
{
switch (j)
{
case :
for (int k = ; k < ; k++)
{
allCard.Add(new RPoker( * k, j, , , (Rank)k, (PokerColour)j));
}
break;
case :
for (int k = ; k < ; k++)
{
allCard.Add(new RPoker( * k, j * , , , (Rank)k, (PokerColour)j));
}
break;
case :
for (int k = ; k < ; k++)
{
allCard.Add(new RPoker( * k, j * , , , (Rank)k, (PokerColour)j));
}
break;
case :
for (int k = ; k < ; k++)
{
allCard.Add(new RPoker( * k, j * , , , (Rank)k, (PokerColour)j));
}
break;
case :
for (int k = ; k < ; k++)
{
allCard.Add(new RPoker( * k, j * , , , (Rank)k + , (PokerColour)j));
}
break;
default:
break;
}
}
}
其中固定的数值，都是在整张图片提取成单张牌时具体尺寸
洗牌代码;
// 定义随机数
Random random = new Random();
// 从数组的最后一个数开始递减
for (int i = allCard.Count - ; i > ; i--)
{
// 随机下标
int index = random.Next(, i);
// 随机出来的数与最后位置的数交换
RPoker temp = allCard[i];
allCard[i] = allCard[index];
allCard[index] = temp;
}
这种随机打乱的洗牌方法可以有很多种，找到合适的方法就可。
两个类完成后，其余的代码都写到到界面Form中，运行后的界面：
主要记录代码编写过程，界面就简单来了。

界面Form1中的代码，逻辑也比较简单，水平所限程序也算完成了，不足之处还望高手能够指出。
