一、游戏背景
参赛人数:2人 准备用具:一副扑克 规则: 扑克牌A,2,3,4,5,6,7,8,9,10,J,Q,K分别代表数字1,2,3,4,5,6,7,8,9,10,11,12,13. 每人轮流取扑克牌,目的是凑成“和”为21点,谁先凑成21谁就胜利。如果没有人凑到21点,就规定最接近21点且小于21点的一方为胜者,每人均可要数次牌,需要注意的是,如果点数和超出21点,就是爆掉了(输了)
二、功能实现
本次游戏的实现一共分为三各类。 分别为:Play(玩家类) 、Poker:(扑克类) 以及RunGame(主游戏界面类)。
Play(玩家类) :
代码语言:javascript复制import java.util.Arrays;
public class Play {
private String name;
private Poker[] pokers;
public Play() {}
public Play(String name) {
super();
this.name=name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Poker[] getPokers() {
return pokers;
}
public void setPoker(Poker[] pokers) {
this.pokers=pokers;
}
@Override
public String toString() {
String info="[暗牌,";
for (int i = 0; i < pokers.length; i ) {
info =pokers[i].toString();
if(i!=pokers.length-1) {
info =",";
}
}
return this.name "n"
info "]";
}
public String getInfo() {
return this.name ":n"
Arrays.toString(this.pokers);
}
/**
* 计算点数
*/
public int getPointers() {
int pointers=0;
int countA=0;
for(Poker poker:pokers) {
//判断是否为A
if(poker.getNumber()==1) {
pointers =11;
countA ;
}else if(poker.getNumber()>10) {
pointers =10;
}else {
pointers =poker.getNumber();
}
}
//判断总点数是否大于21,如果是则减去含有A个数的10
if(pointers>21) {
pointers-=countA*10;
}
return pointers;
}
/**
* 收牌
*/
void getPoker(Poker poker) {
if(this.pokers==null) {
this.pokers=new Poker[1];
}else {
//新建数组
Poker[] newArray=new Poker[pokers.length 1];
//将原有牌赋予新数组
for (int i = 0; i < pokers.length; i ) {
newArray[i]=pokers[i];
}
//让扑克数组,指向新数组
pokers=newArray;
}
//将新牌赋予最后一个数组位置
pokers[pokers.length-1]=poker;
}
}
Poker:(扑克类)
代码语言:javascript复制public class Poker implements Comparable {
//花色四种:0-3
private int type;
//点数:1-13
private int number;
public Poker() {}
public Poker(int type, int number) {
this.type = 0;
this.number = 1;
if (type < 0 || type > 3 || this.number < 1 || this.number > 13) {
return;
}
this.type = type;
this.number = number;
}
public int getType() {
return type;
}
public void setType(int type) {
this.type = type;
}
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
@Override
public String toString() {
String[] types = {"♠", "♥", "♣", "♦"};
String[] pointers = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"};
return types[this.type] pointers[this.number-1];
}
@Override
public int compareTo(Object o) {
if(o==null) {
return -1;
}
if(!(o instanceof Poker)) {
return -1;
}
if(Math.random()>=0.5) {
return 1;
}
return -1;
}
}
RunGame(主游戏界面类)
代码语言:javascript复制import java.util.Arrays;
import javax.swing.JOptionPane;
public class RunGame {
//玩家
private static Play mine;
//电脑
private static Play computer;
//扑克
private static Poker[] pokers;
// 当前可以发牌的位置
private static int pokersIndex = 0;
// 计算机要牌的上限
private static int LIMIT_POINTER = 10;
public static void main(String[] args) {
// 初始化游戏
initGame();
// 显示界面
viewGame();
}
/**
* 显示界面
*/
private static void viewGame() {
boolean flage=true;
while(flage) {
String info="---------------21点游戏-----------------n"
computer "n" mine.getInfo() "n" "1t要牌t2.停牌";
String input=JOptionPane.showInputDialog(info);
if(input==null||input.trim().isEmpty()) {
JOptionPane.showMessageDialog(null, "请正确输入");
continue;
}
switch(input.trim().charAt(0)){
case '1':
//自己要牌
mine.getPoker(pokers[pokersIndex ]);
//电脑要牌
if(computer.getPointers()<LIMIT_POINTER) {
computer.getPoker(pokers[pokersIndex ]);
}
break;
case '2':
//电脑判断是否需要牌
while(computer.getPointers()<LIMIT_POINTER) {
computer.getPoker(pokers[pokersIndex ]);
}
//判断输赢
boolean isWin=true;
if(computer.getPointers()==21) {
//判断谁是 black jack 谁赢,如果都是 black jack 则电脑赢。
isWin=false;
}else if(mine.getPointers()>21) {
isWin=false;
}else if(computer.getPointers() < 21) {
isWin=mine.getPointers()>computer.getPointers();
}
//比较点数,提示结果
info="---------你" (isWin?"赢了":"输了") "--------------------n"
computer.getInfo() " :" computer.getPointers() "n"
mine.getInfo() " :" mine.getPointers() "点";
JOptionPane.showMessageDialog(null, info);
//结束游戏
flage=false;
break;
default:
JOptionPane.showMessageDialog(null, "请正确输入");
continue;
}
}
}
/**
* 初始化游戏
*/
private static void initGame() {
// 构建一副扑克并且洗牌
initPokers();
// 输入玩家姓名
String playerName = JOptionPane.showInputDialog("请输入你的名字");
if (playerName == null || playerName.trim().isEmpty()) {
playerName = "匿名";
}
mine = new Play(playerName);
// 建立电脑玩家
computer = new Play("高进");
// 初始化,每人发两张牌
computer.getPoker(pokers[pokersIndex ]);
mine.getPoker(pokers[pokersIndex ]);
computer.getPoker(pokers[pokersIndex ]);
mine.getPoker(pokers[pokersIndex ]);
}
/**
* 构建一副扑克并且洗牌
*/
private static void initPokers() {
pokers = new Poker[52];
// 循环花色
for (int i = 0; i < 4; i ) {
// 循环点数
for (int j = 1; j < 14; j ) {
int index = i * 13 j - 1;
pokers[index] = new Poker(i, j);
}
}
// 洗牌
/*for (int i = 0; i < 36; i ) {
int posi1 = (int) (Math.random() * 52);
int posi2 = (int) (Math.random() * 52);
swap(pokers, posi1, posi2);
}*/
//利用Comparable接口实现洗牌
Arrays.sort(pokers);
}
private static void swap(Poker[] pokers, int posi1, int posi2) {
Poker temp = pokers[posi1];
pokers[posi1] = pokers[posi2];
pokers[posi2] = temp;
}
}
三、效果展示
1.首先需要输入玩家的名字,如果不输入就会以“匿名”的身份进行游戏。
2.玩家选择是否继续要牌,如果要则输入1,如果停牌则输入2。这里如果玩家选择停牌的话,电脑会进行判断是否继续要牌
四、总结
本次实现的21点小游戏,主要使用Swing组件以及面向对象的思想,游戏本身涉及的技术点不是很多,但是通过这一点一滴小的练习,可以提高自己对以后更深层次学习的兴趣,也是对动手能力的锻炼,继续加油,然后秃见成效!!
