项目需求:


根据输入速率和正确率将玩家分为不同级别,级别越高,一次显示的字符数越多。如果 玩家在规定时间内完成规定次数的输入,正确率达到要求,则玩家升级。最高级别为6级,初始级别为1.项目实现代码如下:


实现项目的代码:


//游戏类
public class Game {
/***
* 玩家属性
*/
public Player play;

public Player getPlay() {
return play;
}

public void setPlay(Player play) {
this.play = play;
}

public Game(Player play) {
this.play = play;
}

/***
* 输出字符串,返回字符串用于和玩家的输入进行比较
* @return
*/
public String printStr() {
StringBuffer sbu=new StringBuffer();
Random rand=new Random(); //产生随机数类
//根据相应的等级,来获得相应的输入次数
int strLength=LevelParam.level[play.getLevelNo()-1].getStrLength();

for(int i=0;i int randNum=rand.nextInt(strLength); //产生随机数
switch(randNum) {
case 0:
sbu.append(">");
break;
case 1:
sbu.append("<");
break;
case 2:
sbu.append("!");
break;
case 3:
sbu.append("#");
break;
case 4:
sbu.append("@");
break;
case 5:
sbu.append("%");
break;
case 6:
sbu.append("&");
break;
case 7:
sbu.append("*");
break;
case 8:
sbu.append("~");
break;
case 9:
sbu.append("?");
break;
}
}
System.out.println(sbu); //输出字符串
return sbu.toString(); //返回字符串
}


/**
* 比较游戏输出out,和玩家输入in,根据结果输出信息
*/
public void prinrResult(String out,String in) {
//输入正确
if(out.equals(in)) {
long currentTime=System.currentTimeMillis();
//如果超时
if((currentTime-play.getStartTime())/1000>LevelParam.level[play.getLevelNo()-1].getTimeLimit()) {
System.out.println("你输入的太慢了,已经超时,退出!");
System.exit(1);
}
//如果没有超时
//计算玩家当前的积分
play.setCurrScore(play.getCurrScore()+LevelParam.level[play.getLevelNo()-1].getPerScore());
//计算已用时间
play.setElapsedTime((int)(currentTime-play.getStartTime())/1000);
//输出玩家当前级别,当前积分,已用时间
System.out.println("输入正确,你的级别是:"+play.getLevelNo()+",你的积分是:"+play.getCurrScore()+",已用时间:"+play.getElapsedTime()+"秒!");

//判断用户是否已经闯过最后一关:等级为6,玩家获得的积分==通过所需要的分数(次数*每次的分数)
if(play.getLevelNo()==6) {
//获得通关所需要的分数
int score=LevelParam.level[play.getLevelNo()-1].getPerScore()*LevelParam.level[play.getLevelNo()-1].getStrTime();
if(score==play.getCurrScore()) {
System.out.println("恭喜你,通关了~");
System.exit(0);
}
}
}else {
//输入错误
System.out.println("输入错误,退出!");
System.exit(1);
}
}


}


//玩家类
public class Player {

/**
* 玩家玩游戏
*/
public void play() {
Scanner input=new Scanner(System.in);

Game game=new Game(this); //this--->指当前对象的引用,传入的值是当前Player类(现在没创建对象)以后创建对象的引用。
//外层循环一次,等级加1
for(int i=0;i //等级加1

//积分清0

//获得每个级别对应的字符串输入字数
int strLength=LevelParam.level[levelNo-1].getStrTime();

//内层循环一次,判断玩家输入的字符串

String out=game.printStr();
//玩家输入

//判断玩家输入的字符串,并输出相应结果
game.prinrResult(out, in);
}
}

}


}


//级别类
public class Level {

}

}


//级别参数类
public class LevelParam {
//对应玩游戏的6个级别
public static final Level level[]=new Level[6];

static {
level[0]=new Level(1,2,10,30,1);
level[1]=new Level(2,3,9,26,2);
level[2]=new Level(3,4,8,22,5);
level[3]=new Level(4,5,7,18,8);
level[4]=new Level(5,6,6,15,10);
level[5]=new Level(6,7,5,12,15);
}
}


//测试类
public class Test {
public static void main(String[] args) {
Player p = new Player();
p.play();
}
}
