用Java实现一个简易的炸金花小游戏

最近闲暇时间写了个用Java实现的简易版的炸金花小游戏，还是很有趣的，下面具体来介绍下具体实现。
下面这个是初始化页面。

一、设计思路
1、首先要了解炸金花的游戏规则，针对整个游戏过程来考虑。从游戏开始后的抽牌选出庄家，再到洗牌及发牌阶段，接着投注或比牌，最终决出胜者。
2、在这整个过程中需要涉及洗牌算法，及比牌时的规则编写，电脑端投注或比牌等一系列操作。
3、在整个过程中需要考虑到各种情况，比如弃牌后不能再参与，首轮不能直接比牌等等。

游戏实际运行主界面如下：

二、代码实现：
1.初始化过程中的选出庄家，代码如下：

public void initGame() {Random rand=new Random();List<Integer> reduce=new ArrayList<>();if(this.t!=null) {this.t.isPublish = true;}for(int i=0;i<playerList.length;i++) {int j=0;if(reduce.isEmpty()) {j=rand.nextInt(card.length);reduce.add(j);}else {j=rand.nextInt(card.length);while(reduce.contains(j)) {j=rand.nextInt(card.length);}reduce.add(j);}	switch (i) {case 0:CommonUtil.move(card[j], card[j].getLocation(), new Point(100, 200));card[j].turnFront();break;case 1:CommonUtil.move(card[j], card[j].getLocation(), new Point(390, 515));card[j].turnFront();break;case 2:CommonUtil.move(card[j], card[j].getLocation(), new Point(800, 200));card[j].turnFront();break;case 3:		CommonUtil.move(card[j], card[j].getLocation(), new Point(390, 60));card[j].turnFront();break;}playerList[i].add(card[j]);container.setComponentZOrder(card[j], 0);}try {Thread.sleep(2000);} catch (InterruptedException e) {return;}if(this.t!=null) {this.t.isPublish = false;}confirmBanker(playerList);for(Integer index : reduce) {		card[index].turnRear();card[index].setLocation(400, 250);}for(int i=0;i<inigoldLabel.length;i++) {inigoldLabel[i].setVisible(true);container.setComponentZOrder(inigoldLabel[i],0);playerGold[i]-=initGold;playergoldLabel[i].setText(playerGold[i]+"");}//设置开、放位置openCardIcon[0].setLocation(95, 185);quitCardIcon[0].setLocation(135, 185);//openCardIcon[1].setLocation(125, 210);quitCardIcon[1].setLocation(545, 520);openCardIcon[2].setLocation(795, 185);quitCardIcon[2].setLocation(835, 185);openCardIcon[3].setLocation(535, 80);quitCardIcon[3].setLocation(575, 80);}

2.选出庄家后开始发牌，代码如下：

public void publishCard() {for(int i=0;i<4;i++) {isFirst[i]=false;currPlayerGold[i]=10;}int t=0;int count=0;if(this.t!=null) {this.t.isPublish = true;}for(int i=currIndex;i<card.length;i++) {if(count==12) {currIndex=i-1;break;}switch (t++%4) {case 0:CommonUtil.move(card[i], card[i].getLocation(), new Point(90, 250+i*4));playerList[0].add(card[i]);break;case 1:CommonUtil.move(card[i], card[i].getLocation(), new Point(420+i*6, 510));playerList[1].add(card[i]);break;case 2:CommonUtil.move(card[i], card[i].getLocation(), new Point(810, 250+i*4));playerList[2].add(card[i]);break;case 3:CommonUtil.move(card[i], card[i].getLocation(), new Point(420+i*6, 50));playerList[3].add(card[i]);break;}container.setComponentZOrder(card[i], 0);count++;}if(this.t!=null) {this.t.isPublish = false;}for(int i=0;i<4;i++) {CommonUtil.cardSort(playerList[i]);CommonUtil.rePosition(playerList[i], i,this);}		if(bankerFlag==1) {container.setComponentZOrder(laid,0);laid.setVisible(true);}if(bankerFlag==1) {time[1].setVisible(true);			}}

3.在比牌时需要判断双方之间牌面大小，代码实现：

public static int checkCards(List<Card> clist,List<Card> chooselist) {CardType cType=judgeCard(clist);CardType chooseType=judgeCard(chooselist);if(cType==CardType.c3 && getValue(clist.get(0))==14) {return 1;}if(chooseType==CardType.c3 && getValue(chooselist.get(0))==14) {return 0;}if(cType==CardType.c3 && chooseType!=CardType.c3) {return 1;}if(cType!=CardType.c3 && chooseType==CardType.c3) {return 0;}if(cType==chooseType) {if(cType==CardType.c3 && getValue(clist.get(0))>getValue(chooselist.get(0))) {return 1;}else if(cType==CardType.c2) {List<Card> c1=getOrder(clist);List<Card> c2=getOrder(chooselist);if(getValue(c1.get(0))>getValue(c2.get(0))) {return 1;}if(getValue(c1.get(0))==getValue(c2.get(0))) {//比较大小、花色if(getValue(c1.get(1))==getValue(c2.get(1))) {if(getColor(c1.get(1))<getColor(c2.get(1))) {return 1;}}else {if(getValue(c1.get(1))>getValue(c2.get(1))) {return 1;}}}else {if(getValue(c1.get(0))>getValue(c2.get(0))) {return 1;}}}else if(cType==CardType.c30123) {if(getValue(clist.get(0))>getValue(chooselist.get(0))) {return 1;}else {if(getValue(clist.get(0))==getValue(chooselist.get(0))) {//相同if(getColor(clist.get(0))<getColor(chooselist.get(0))) {return 1;}}}}else if(cType==CardType.c30 || cType==CardType.c1) {if(isSameCard(clist, chooselist)) {if(getColor(clist.get(0))<getColor(chooselist.get(0))) {return 1;				}}else {return compareCard(clist, chooselist);}}else if(cType==CardType.c123) {if(getValue(clist.get(0))>getValue(chooselist.get(0))) {return 1;}}			}else {if(cType==CardType.c30123) {return 1;}if(cType==CardType.c30 && chooseType!=CardType.c30123) {return 1;}if(cType==CardType.c123 && chooseType!=CardType.c30123 && chooseType!=CardType.c30) {return 1;}if(cType==CardType.c2 && chooseType!=CardType.c30123 && chooseType!=CardType.c30 && chooseType!=CardType.c123) {return 1;}}return 0;}

接着编写Swing主界面：

完成后启动main方法就可以了。
