上学期刚开学的时候我特别沉迷于斗地主 充了6块钱赢了30万豆 然后一夜之间破产 越想越气  
然后我就有一个大胆的想法开发一个斗地主现在这个斗地主能在控制台上运行  
本文主要讲解我在开发斗地主时研究的算法思路  
现在算是一个半成品吧 差个图形界面和一个socket就能联机对战了  
后来我又沉迷上了王者荣耀到这学期才想起我还有个斗地主的源码所以今天想在这里和大家分享一下

# 一、先定义个常量的类 #

package com.liziguo.ddz;
    
    /**

    public class GameConstants {
        
    
    	public static final int NUM_3 = 0;

    	public static final int ID_4_3 = 6;
    	public static final int ID_4_4 = 7;
    	public static final int ID_5_1 = 8;
    	public static final int ID_5_2 = 9;
    	public static final int ID_5_3 = 10;
    	public static final int ID_5_4 = 11;
    	public static final int ID_6_1 = 12;
    	public static final int ID_6_2 = 13;
    	public static final int ID_6_3 = 14;
    	public static final int ID_6_4 = 15;
    	public static final int ID_7_1 = 16;
    	public static final int ID_7_2 = 17;
    	public static final int ID_7_3 = 18;
    	public static final int ID_7_4 = 19;
    	public static final int ID_8_1 = 20;
    	public static final int ID_8_2 = 21;
    	public static final int ID_8_3 = 22;
    	public static final int ID_8_4 = 23;
    	public static final int ID_9_1 = 24;
    	public static final int ID_9_2 = 25;
    	public static final int ID_9_3 = 26;
    	public static final int ID_9_4 = 27;
    	public static final int ID_10_1 = 28;
    	public static final int ID_10_2 = 29;
    	public static final int ID_10_3 = 30;
    	public static final int ID_10_4 = 31;
    	public static final int ID_J_1 = 32;
    	public static final int ID_J_2 = 33;
    	public static final int ID_J_3 = 34;
    	public static final int ID_J_4 = 35;
    	public static final int ID_Q_1 = 36;
    	public static final int ID_Q_2 = 37;
    	public static final int ID_Q_3 = 38;
    	public static final int ID_Q_4 = 39;
    	public static final int ID_K_1 = 40;
    	public static final int ID_K_2 = 41;
    	public static final int ID_K_3 = 42;
    	public static final int ID_K_4 = 43;
    	public static final int ID_A_1 = 44;
    	public static final int ID_A_2 = 45;
    	public static final int ID_A_3 = 46;
    	public static final int ID_A_4 = 47;
    	public static final int ID_2_1 = 48;
    	public static final int ID_2_2 = 49;
    	public static final int ID_2_3 = 50;
    	public static final int ID_2_4 = 51;
    	public static final int ID_JOKER_1 = 52;
    	public static final int ID_JOKER_2 = 53;
    
    	public static final int TYPE_ERROR = -1;
    	public static final int TYPE_NULL = 0;
    	public static final int TYPE_1 = 1;
    	public static final int TYPE_22 = 2;
    	public static final int TYPE_333 = 3;
    	public static final int TYPE_BOOM = 4;
    	public static final int TYPE_3331 = 5;
    	public static final int TYPE_33322 = 6;
    	public static final int TYPE_444412 = 7;
    	public static final int TYPE_44441122 = 8;
    	public static final int TYPE_34567 = 9;
    	public static final int TYPE_334455 = 10;
    	public static final int TYPE_333444 = 11;
    	public static final int TYPE_33344412 = 12;
    	public static final int TYPE_3334441122 = 13;
    }

ID\_3\_1 指的是方块三  
ID\_K\_2 指的是梅花十三（梅花K 哈哈哈伍六七看多了）区分花色  
NUM\_3 指的是三 不区分花色  
小提示：用id/4就能得出这张牌的num了  
然后type的都是牌型了 相信打过斗地主的都看得懂吧

# 二、定义牌的实体类 #

package com.liziguo.ddz;
    
    /**
     * @Author: Liziguo
     * @Date: 2020/9/12 11:22
     */
    public class Card {
        
    
    	public final int id;
    	public final int num;
    
    	public Card(int id) {
        
    		this.id = id;
    		num = id / 4;
    	}
    
    	/**
    	 * 这个构造方法是用来做测试用的
    	 *
    	 * @param s
    	 */
    	public Card(String s) {
        
    		if ("C".equals(s)) {
        
    			id = GameConstants.ID_JOKER_2;
    			num = id / 4;
    			return;
    		}
    		switch (s) {
        
    			case "3":
    				num = GameConstants.NUM_3;
    				break;
    			case "4":
    				num = GameConstants.NUM_4;
    				break;
    			case "5":
    				num = GameConstants.NUM_5;
    				break;
    			case "6":
    				num = GameConstants.NUM_6;
    				break;
    			case "7":
    				num = GameConstants.NUM_7;
    				break;
    			case "8":
    				num = GameConstants.NUM_8;
    				break;
    			case "9":
    				num = GameConstants.NUM_9;
    				break;
    			case "0":
    				num = GameConstants.NUM_10;
    				break;
    			case "J":
    			case "j":
    				num = GameConstants.NUM_J;
    				break;
    			case "Q":
    			case "q":
    				num = GameConstants.NUM_Q;
    				break;
    			case "K":
    			case "k":
    				num = GameConstants.NUM_K;
    				break;
    			case "1":
    			case "A":
    			case "a":
    				num = GameConstants.NUM_A;
    				break;
    			case "2":
    				num = GameConstants.NUM_2;
    				break;
    			case "c":
    				num = GameConstants.NUM_JOKER;
    				break;
    			default:
    				throw new RuntimeException();
    		}
    		id = num * 4;
    	}
    
    	public boolean is2() {
        
    		return num == GameConstants.NUM_2;
    	}
    
    	public boolean isJoker() {
        
    		return num == GameConstants.NUM_JOKER;
    	}
    
    	@Override
    	public String toString() {
        
    		switch (num) {
        
    			case GameConstants.NUM_3:
    				return "3";
    			case GameConstants.NUM_4:
    				return "4";
    			case GameConstants.NUM_5:
    				return "5";
    			case GameConstants.NUM_6:
    				return "6";
    			case GameConstants.NUM_7:
    				return "7";
    			case GameConstants.NUM_8:
    				return "8";
    			case GameConstants.NUM_9:
    				return "9";
    			case GameConstants.NUM_10:
    				return "10";
    			case GameConstants.NUM_J:
    				return "J";
    			case GameConstants.NUM_Q:
    				return "Q";
    			case GameConstants.NUM_K:
    				return "K";
    			case GameConstants.NUM_A:
    				return "A";
    			case GameConstants.NUM_2:
    				return "2";
    			case GameConstants.NUM_JOKER:
    				if (id == GameConstants.ID_JOKER_1) return "小王";
    				else return "大王";
    		}
    		return null;
    	}
    
    }

第二个构造方法是做测试用的  
注意：这里用大小写的C代替大小王，0代表10，1和A都能代表A  
其他没什么好说的了

package com.liziguo.ddz;
    
    /**
     * @Author: Liziguo
     * @Date: 2020/9/12 18:53
     */
    public class CardGroup {
        
    	public final int num;
    	public int sum;
    
    	public CardGroup(int num, int sum) {
        
    		this.num = num;
    		this.sum = sum;
    	}
    
    	@Override
    	public String toString() {
        
    		return "(" + "num=" + num + ", sum=" + sum + ')';
    	}
    }

# 三、创建工具类 #

package com.liziguo.ddz;
    
    import java.util.*;
    import java.util.stream.Collectors;

    	public static List<Card> CreateCards(String cards) {
        
    		List<Card> list = new ArrayList<>();
    		for (int i = 0; i < cards.length(); i++) {
        
    			String s = cards.substring(i, i + 1);
    			if (!" ".equals(s)) list.add(new Card(s));
    		}
    		return list;
    	}
    
    	/**

    		Map<Integer, Integer> map = new HashMap<>();// key=cardNum value=sum
    		while (temp.size() > 0) {
        
    			final Card card = temp.removeLast();
    			final Integer sum = map.get(card.num);
    			if (sum == null)
    				map.put(card.num, 1);
    			else
    				map.put(card.num, sum.intValue() + 1);
    		}
    		for (Map.Entry<Integer, Integer> entry : map.entrySet()) {

    	}

工具类中包含了一些待会要用到的方法

这个类主要写的是解析牌型的算法 例如我打出`333A`让电脑判断我打的是三带一还是四带二  
大部分的牌型还是比较好判断的 这里就不一一列举了

> 简单的只挑这一个讲  
> 这个方法可以判断玩家出的这一组牌是不是三带一  
> 首先看一下这条语句`if (groups.get(0).sum == 3 && groups.get(0).num != GameConstants.NUM_JOKER)`  
> groups是一个列表排序方式是按sum从大到小排（list是按id从大到小排）  
> 首先判断最多的那张牌是不是有3张 再判断他是不是3张王 如果是那就是王炸了 王炸是不能带单排的  
> 如果条件成立 那剩下那张牌就不用管它了 它肯定不会和那三张牌一样 也肯定只有一张牌  
> 所以说 你带啥都行 不关我事

比较复杂的是`is33344412()`和`is3334441122()`的这两个方法

##### 先看看这个方法-飞机带单排： #####

> 飞机带翅膀是这游戏最复杂的部分了  
> 我的思路是先把大于等于3张牌的牌号找出来  
> 例如传进来的牌是33344412这是最简单的情况  
> 把大于等于三张的牌取出来得到333和444  
> 判断他们是否连续所以这里机身就是333444  
> 刚好差剩下的两张牌可以组成飞机带翅膀

> 上面这种算法已经可以满足很多种情况了不过还是有很多bug的（下面10用0表示）  
> 例如我们要打的是JJJ 000 999 888 777 666 555 333电脑人就傻了  
> 当然这种情况一般不会出现 但是我想玩一把每人50张牌斗地主的话系统就会崩溃  
> 我们用之前的算法来分析一下  
> 先把三顺找出来得到JJJ 000 999 888 777 666 555然后剩下的3张牌无法组成翅膀啊 组成翅膀要7张牌  
> 有没有发现如果我把飞尾的555从机身取出来装到机翼上刚好可以组成JJJ 000 999 888 777 666带555 333  
> 其实把JJJ取出来当成机翼也是可以的 如果你想切机头的话可以参考下飞机带对子的写法  
> 但是这样写的话出牌就存在不确定性 需要弹出提示框让玩家自行选择

> 还没有完  
> 如果我们传入的牌是333 444 666 777 888 999 000 JJJ电脑人又傻了

> 按之前的算法电脑只能找到机身333444这时候电脑就发话了 你这机身多大自己心里没点数吗还想带18张单排？  
> 这样的话我们就要把每个三顺都存到一个集合里 让每一个三顺都当一遍机身 得到最优解

> 如果有发现我没有考虑到的情况请看完全文后 欢迎留言评论

##### 再看看这个方法-飞机带对子： #####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTA3NTYwNDY_size_16_color_FFFFFF_t_70 4]

> 飞机带对子写法和飞机带单排大致相似  
> 不同的地方有：  
> 1.飞机带单牌的的话如33344412我们是直接把333444取出来 然后判断单排的数量是否满足条件  
> 而飞机带对子的话你需要将剩下的牌再做一个判断  
> 如3334441122把333444取出来后得到两组牌 分别是两张1两张2  
> 只要剩下的牌的数量是偶数就能成立

> 2.飞机带对子是需要切飞机头的  
> 为了解决以下两种情况  
> 334445556667777 -> 666555444 77 77 33 切机头  
> 334444555666777 -> 777666555 44 44 33 切机尾  
> 如果使用切机尾的方法那么第一个电脑将识别不了  
> 切机身的思路大概是这样的 如果只切一个机身那么333444555 先切掉555进行判断 再切333  
> 如果切两个机身那么333444555666 先切掉666555 然后切666333 再切444333

##### 构造方法： #####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTA3NTYwNDY_size_16_color_FFFFFF_t_70 5]

> 让我们再看看构造方法  
> 为什么if(is444412())之后的方法不直接return呢  
> 因为有些牌型是可以被解析为四带两对和飞机带翅膀的  
> 例如33334444可以被解析为 四个3带两个对4 四个4带两个对3 和333444带34的飞机 当然还可以解析成连炸

> 我的斗地主规则是参考腾讯欢乐斗地主手游的 欢乐斗地主没有连炸所以我这也没有  
> 据说在斗地主职业比赛中打出这种牌型是要玩家指定牌型的 什么斗地主也有打职业的？  
> 而在腾讯的欢乐斗地主中打出33334444并没有让玩家指定牌型  
> 会被解析成四带两对 不要问我是怎么知道的 这个答案是我用豆子换来的  
> 既然腾讯都没有这么做那我们也不这么做

> 我的算法是这样的 会把这种有多重牌型的牌存到一个集合里(CardProducts这个类里)  
> 如果上家出的牌是四带两对就 那打出33334444就会被解析成四带两对  
> 如果上家出的牌是飞机就 那打出33334444就会被解析成飞机  
> 如果是你先出牌 打出33334444就会跟腾讯斗地主一样解析成四带两对

> 而33334444到底是被解析为 四个3带两个对4 还是四个4带两个对3呢 估计没哪个傻子会这么打吧  
> 这里我不好做测试 毕竟豆子有限 能拿到这样牌的机会也不多  
> 而且还要上家也有四带两对才能测出来 非常需要运气成分  
> 所以我把33334444默认解析成大的牌带小的牌 即四个4带两个对3

这个类很简单`maxCard`并不一定是指最大的那张牌  
举个例子吧：

> 顺子：34567的`maxCard`是7  
> 三带一：5556的`maxCard`是5  
> 飞机带翅膀：777666A4的`maxCard`是7

> 懂了吧 这个属性是用来比大小的 被带的牌是不会被算上的

`isGreaterThan(CardProduct cardProduct)`用来比较大小  
这里的炸弹也严格按照欢乐斗地主的规则

> 四炸<双王炸<五炸<六炸<三王炸<七炸<八炸<四王炸  
> 以此类推  
> 并且`[大王, 大王]`是可以打赢`[大王, 小王]`和`[小王, 小王]`的

# 六、提示功能 #

每个斗地主游戏都有一个提示功能 根据上一家出的牌从小到大提示接下来你该怎么打

> 例：当前扑克牌:\[6, K, 2, 小王, 大王\] 上家出牌:\[A\] 提示:\[\[2\], \[小王\], \[大王\], \[小王, 大王\]\]
