独自一人开发斗地主游戏（h5 + 安卓 + 苹果）
开篇感言
不枉我深入学习基础知识，算法与数据结构，编译原理，java并发编程，这些东西都有用得到的时候。
再极端的时间内学习了cocos creator引擎，并学以致用，有极大的增加了自己的自信心。
在公司总是拧螺丝，一个人开发一个完成的作品，我又觉得自己彷佛回到了色彩斑斓的世界中。
前端代码地址：https://github.com/neroHua/neroGameClient
后端代码地址：https://github.com/neroHua/neroGameServer
背景
本人使用java工作已经7年之多了，js和ts基本懂一些。
打算开发一款逮狗腿子的棋牌游戏（合同学们玩），先仿制一款斗地主游戏，试一下。
涉及到的知识点技能
编码功底：
- 算法和数据结构
- 设计模式（策略，责任链）
- 敏捷开发。
游戏引擎：
1.Cocos creator 2.0.4
网络通信：
1. http
2. websocket
编程语言：
1.java （后端）
2.typeScript（前端）
后端：
1.spring，springMVC，spring boot， mybatis
2.flyway，jwt，h2，junit
前端：
h5
架构设计及其思路
- 服务器整体为单机结构（以后有需要，再扩容好了），提供 h5，安卓，苹果 三种客户端接入服务器，且前端由Cocos 引擎处理，直接打包成三个端 。
- 客户端和服务器端的通信协议选择为http，和 websocket （三端都支持的通信方式）。用户点击等等事件由客户端发送http请求。通过websocket，服务器向客户端推送消息。服务器端不接收用户通过websocket推送到服务器的消息。只用用户进入房间以后，才会开启websocket通信。
- 游戏的主要模型/功能设计。用户，房间，游戏，游戏控制器，游戏回合。房间是核心： 用户再房间里面玩游戏。每一个房间都有一个游戏控制器用以控制游戏的进程。用户有手牌。游戏控制器，通过游戏回合控制每回合的进行。
详细设计
1 单张卡牌设计
为了便于，排序，比较，等操作，设计如下：
这里的code呢，等于卡牌前端的图片名称（不过我这里前端使用的图集）。
这里的value呢，代表了单张卡牌的权值大小，可用于比较牌面的大小。
这里的message呢，代表了卡牌的中文名称。
这里不需要花色，所以没有设计花色字段

CardEnumeration(String code, int value, String message) {
this.code = code;

this.message = message;
}
}
2 打牌时，卡牌组合的牌型设计
为了便于，排序，比较，等操作，设计如下：
权值大的牌型，比权值小的牌型大。
权值相同的牌型，需要牌型一样（牌型为同一个枚举）方可比较
这里的code呢，一种编码。
这里的value呢，代表的组合的权值。
这里的message呢，代表了卡牌的中文名称。
逮狗腿子，有些牌型不支持，还需要更多的牌型，后面再弄了，不过思路是已经想好了。
package com.nero.hua.enumeration;
import lombok.Getter;
@Getter
public enum PlayCardTypeEnumeration {
SINGLE("single", 0, "单牌"),
STRAIGHT("straight", 0, "顺子"),
PAIR("pair", 0, "对子"),
PAIR_STRAIGHT("pairStraight", 0, "连对"),
TRIPLE("triple", 0, "三不带"),
TRIPLE_SINGLE("tripleSingle", 0, "三带一"),
TRIPLE_PAIR("triplePAIR", 0, "三带一对"),
AIRPLANE("airplane", 0, "飞机不带"),
AIRPLANE_SINGLE("airplaneSingle", 0, "飞机带单"),
AIRPLANE_PAIR("airplanePair", 0, "飞机带对"),
FOUR_SINGLE("fourSingle", 0, "4带2"),
FOUR_PAIR("fourPair", 0, "4带2对"),
BOMB("bomb", 1, "炸弹"),
BOMB_KING("bombKing", 2, "王炸");
private String code;
private int value;
private String message;
PlayCardTypeEnumeration(String code, int value, String message) {
this.code = code;
this.value = value;
this.message = message;
}
}
3 一种通用的牌型及其比较算法
1.为了便于比较牌型，先把牌按照一定格式格式化, 比如下面的。（对于有变种的牌型可以让客户端选择）
/**
* 客户端需要根据牌型把本字段格式化并排序降低服务器计算压力
*
* 比如
* 顺子：7, 6, 5, 4, 3
* 对子：5，5, 4, 4, 3, 3
* 三带一: 3, 3, 3, 2
* 三带对: 3, 3, 3, 2, 2
* 飞机带单: 4, 4, 4, 3, 3, 3, 2, 1
* 飞机带对: 4, 4, 4, 3, 3, 3, 2, 2, 1, 1
* 王炸：大王, 小王
*
*/
2.对于格式化后的牌型，比较的办法如下：
public static boolean currentPlayCardListBetterThanLastPlayCardList(UserPlayCardTurnMO lastUserPlayCardTurnMO, List<CardEnumeration> playCardList, PlayCardTypeEnumeration playCardTypeEnumeration) {
if (null == lastUserPlayCardTurnMO) {
return Boolean.TRUE;
}
PlayCardTypeEnumeration lastPlayCardTypeEnumeration = lastUserPlayCardTurnMO.getPlayCardTypeEnumeration();
if (playCardTypeEnumeration.getValue() < lastPlayCardTypeEnumeration.getValue()) {
return Boolean.FALSE;
}
else if (playCardTypeEnumeration.getValue() > lastPlayCardTypeEnumeration.getValue()) {
return Boolean.TRUE;
}
if (lastPlayCardTypeEnumeration != playCardTypeEnumeration) {
return Boolean.FALSE;
}
List<CardEnumeration> lastPlayCardList = lastUserPlayCardTurnMO.getCardList();
return lastPlayCardList.size() == playCardList.size()
&& lastPlayCardList.get(0).getValue() < playCardList.get(0).getValue();
}
- 牌型的格式化算法
整体式为： 把牌按照相同单牌权值的数量的大小进行分割成小块，再根据数量的大小把小块合并。把原来的大块按照单牌权值的大小进行排序，可以方便上诉操作
public static int formatCardList(List<CardEnumeration> playCardList) {
Map<Integer, Integer> playCardValueCountMap = getPlayCardValueCountMap(playCardList);
quickSortOneCardList(0, playCardList.size() - 1, playCardList);
Map<Integer, List<CardEnumeration>> playCardCountListMap = getPlayCardCountListMap(playCardList, playCardValueCountMap);
List<Integer> countList = getSortedPlayCardCountList(playCardCountListMap);
for (int i = 0, k = 0; i < countList.size(); i++) {
List<CardEnumeration> cardEnumerationList = playCardCountListMap.get(countList.get(i));
for (int j = 0; j < cardEnumerationList.size(); j++) {
playCardList.set(k, cardEnumerationList.get(j));
k++;
}
}
return countList.get(0);
}
计算单牌权值及其数量Map
private static Map<Integer, Integer> getPlayCardValueCountMap(List<CardEnumeration> playCardList) {
Map<Integer, Integer> playCardValueCountMap = new HashMap<>();
for (int i = 0; i < playCardList.size(); i++) {
Integer count = playCardValueCountMap.get(playCardList.get(i).getValue());
if (null == count) {
playCardValueCountMap.put(playCardList.get(i).getValue(), 1);
}
else {
playCardValueCountMap.put(playCardList.get(i).getValue(), count + 1);
}
}
return playCardValueCountMap;
}
对牌按照单牌权值递减的顺序进行排序（这里使用快排）
public static void quickSortOneCardList(int start, int end, List<CardEnumeration> cardList) {
if (start >= end) {
return;
}
CardEnumeration keyCard = cardList.get(start);
int i = start;
int j = end;
while (i != j) {
if (cardList.get(i).getValue() < keyCard.getValue()) {
CardEnumeration temp = cardList.get(j);
cardList.set(j, cardList.get(i));
cardList.set(i, temp);
j--;
}
else {
i++;
}
}
int middle = cardList.get(i).getValue() >= keyCard.getValue() ? i : i - 1;
if (middle >= start && middle <= end) {
CardEnumeration temp = cardList.get(middle);
cardList.set(middle, cardList.get(start));
cardList.set(start, temp);
}
quickSortOneCardList(start, middle - 1, cardList);
quickSortOneCardList(middle + 1, end, cardList);
}
把已经排序好的牌，按照相同单牌权值的数量，平滑分割成多个小数组
private static Map<Integer, List<CardEnumeration>> getPlayCardCountListMap(List<CardEnumeration> sortedPlayCardList, Map<Integer, Integer> playCardValueCountMap) {
Map<Integer, List<CardEnumeration>> playCardCountListMap = new HashMap<>();
for (Integer i : playCardValueCountMap.keySet()) {
playCardCountListMap.put(playCardValueCountMap.get(i), new LinkedList<>());
}
for (int i = 0; i < sortedPlayCardList.size(); i++) {
CardEnumeration cardEnumeration = sortedPlayCardList.get(i);
Integer count = playCardValueCountMap.get(cardEnumeration.getValue());
List<CardEnumeration> cardEnumerationList = playCardCountListMap.get(count);
cardEnumerationList.add(cardEnumeration);
}
return playCardCountListMap;
}
把相同单牌权值的数量进行排序（由大到小）
private static List<Integer> getSortedPlayCardCountList(Map<Integer, List<CardEnumeration>> playCardCountListMap) {
List<Integer> countList = new ArrayList<>();
for (Integer i : playCardCountListMap.keySet()) {
countList.add(i);
}
selectionSort(countList);
return countList;
}
public static void selectionSort(List<Integer> countList) {
if (1 == countList.size()) {
return;
}
for (int i = 0; i < countList.size() - 1; i++) {
Integer current = countList.get(i);
for (int j = i + 1; j < countList.size(); j++) {
Integer tobeCompared = countList.get(j);
if (tobeCompared > current) {
countList.set(i, tobeCompared);
countList.set(j, current);
current = tobeCompared;
}
}
}
}
把按照相同单牌权值数量分割的碎片，根据数量的大小拼接起来
for (int i = 0, k = 0; i < countList.size(); i++) {
List<CardEnumeration> cardEnumerationList = playCardCountListMap.get(countList.get(i));
for (int j = 0; j < cardEnumerationList.size(); j++) {
playCardList.set(k, cardEnumerationList.get(j));
k++;
}
}
- 对格式化的牌进行牌型的识别
可以使用责任链模式，对于变种的可以可以处理。（playCardTypeValidateList 可以通过spring或者静态代码初始化进去），这种方式比较面向对象，看着更加优雅。不过考虑牌型的概率分布我使用了另外一种方式。
for (PlayCardTypeValidate playCardTypeValidate : playCardTypeValidateList) {
if (playCardTypeValidate.match(formattedPlayCardList)) {
playCardTypeMap.put(playCardTypeValidate.getPlayCardTypeEnumeration(), formattedPlayCardList);
break;
}
}
对于格式化好的三带二可以使用下面的代码识别。
package com.nero.hua.validate.impl;
import com.nero.hua.enumeration.CardEnumeration;
import com.nero.hua.enumeration.PlayCardTypeEnumeration;
import com.nero.hua.validate.PlayCardTypeValidate;
import java.util.List;

private static final int MIN_COUNT = 10;
private static final int GROUP_COUNT = 5;
private static final int TRIPLE_COUNT = 3;
@Override
public PlayCardTypeEnumeration getPlayCardTypeEnumeration() {
return PlayCardTypeEnumeration.AIRPLANE_PAIR;
}
@Override
public boolean match(List<CardEnumeration> cardEnumerationList) {
if (cardEnumerationList.size() < MIN_COUNT) {
return Boolean.FALSE;
}
if (0 != cardEnumerationList.size() % GROUP_COUNT) {
return Boolean.FALSE;
}
for (int i = 0; i < cardEnumerationList.size() / GROUP_COUNT; i += 3) {
if (cardEnumerationList.get(i).getValue() != cardEnumerationList.get(i + 1).getValue()
|| cardEnumerationList.get(i + 1).getValue() != cardEnumerationList.get(i + 2).getValue()) {
return Boolean.FALSE;
}
}
for (int i = 0; i < cardEnumerationList.size() / GROUP_COUNT; i += 3) {
if (cardEnumerationList.get(i).getValue() - 1 != cardEnumerationList.get(i + 3).getValue()) {
return Boolean.FALSE;
}
}
if (cardEnumerationList.get(0).getValue() >= CardEnumeration.CARD_415.getValue()) {
return Boolean.FALSE;
}
int lastTripleStartIndex = this.calculateLastTripleStartIndex(cardEnumerationList.size());
for (int i = lastTripleStartIndex + 3; i < cardEnumerationList.size(); i += 2) {
if (cardEnumerationList.get(i).getValue() != cardEnumerationList.get(i + 1).getValue()) {
return Boolean.FALSE;
}
}
return Boolean.TRUE;
}
private int calculateLastTripleStartIndex(int size) {
return (size / GROUP_COUNT - 1) * TRIPLE_COUNT;
}
}
