下面展示一些 内联代码片

// An highlighted block
package com.yc.opp3.hc0701;

public class Hero {
	private int level;
	private int  blood;
	private int att;
	private int def;
	private int gold;
	private int rKey;
	private int yKey;
	private int bKey;
	private int exp;
	
	
	public Hero() {
		
		this.level = 1;
		this.blood = 1000;
		this.att = 10;
		this.def = 10;
		this.gold = 0;
		this.rKey = 1;
		this.yKey = 1;
		this.bKey = 1;
		this.exp = 0;
	}
	public int getExp() {
		return exp;
	}
	public void setExp(int exp) {
		this.exp = exp;
	}
	@Override
	public String toString() {
		return "勇士等级为:" + level + ", 血量为:" + blood + ", 攻击为:" + att + ", 防御为:" + def + ", 金币为:" + gold
				+ ", 红钥匙:" + rKey + ", 黄钥匙:" + yKey + ", 蓝钥匙:" + bKey + ", 经验:" + exp ;
	}
	public int getLevel() {
		return level;
	}
	public void setLevel(int level) {
		this.level = level;
	}
	public int getBlood() {
		return blood;
	}
	public void setBlood(int blood) {
		this.blood = blood;
	}
	public int getAtt() {
		return att;
	}
	public void setAtt(int att) {
		this.att = att;
	}
	public int getDef() {
		return def;
	}
	public void setDef(int def) {
		this.def = def;
	}
	public int getGold() {
		return gold;
	}
	public void setGold(int gold) {
		this.gold = gold;
	}
	public int getrKey() {
		return rKey;
	}
	public void setrKey(int rKey) {
		this.rKey = rKey;
	}
	public int getyKey() {
		return yKey;
	}
	public void setyKey(int yKey) {
		this.yKey = yKey;
	}
	public int getbKey() {
		return bKey;
	}
	public void setbKey(int bKey) {
		this.bKey = bKey;
	}
	
	
	
}

二、怪物类

	怪物类有怪物名,血量,攻击,防御,击败后获得金币数和经验值的属性
	下面展示一些 `内联代码片`。
// An highlighted block
package com.yc.opp3.hc0701;

public class Monster {
	private String name;
	private int blood;
	private int att;
	private int def;
	private int gold;
	private int exp;
	
	
	public Monster(String name, int blood, int att, int def, int gold, int exp) {
		super();
		this.name = name;
		this.blood = blood;
		this.att = att;
		this.def = def;
		this.gold = gold;
		this.exp = exp;
	}
	@Override
	public String toString() {
		return "怪物名:" + name + ", 血量:" + blood + ", 攻击:" + att + ", 防御:" + def + ", 金币:" + gold
				+ ", 经验:" + exp ;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getBlood() {
		return blood;
	}
	public void setBlood(int blood) {
		this.blood = blood;
	}
	public int getAtt() {
		return att;
	}
	public void setAtt(int att) {
		this.att = att;
	}
	public int getDef() {
		return def;
	}
	public void setDef(int def) {
		this.def = def;
	}
	public int getGold() {
		return gold;
	}
	public void setGold(int gold) {
		this.gold = gold;
	}
	public int getExp() {
		return exp;
	}
	public void setExp(int exp) {
		this.exp = exp;
	}
	
	
}

三、地图类

	地图类用一个二维数组来存储地图,第一个下标表示塔的层数,第二个下标表示具体地图

下面展示一些 内联代码片

// An highlighted block
package com.yc.opp3.hc0701;

public class Maps {
	//这个地图20层,每层10*10
	public static String[][] maps = new String[20][100];
	
	static  {
		// TODO Auto-generated constructor stub
		//创建地图
		//x表示强 ,h 勇士,a红宝石 d蓝宝石,r红血瓶  b 蓝雪平 ,1-9 表示怪物
		//空格表示空地 ijk三种钥匙  IJK三种门
		//n 下一层  p上一层
		maps[0] = new String[] {
				"x","x","x","x","x","x","x","x","x","x",	
				"x","a","d","x","a","x","d","3","n","x",
				"x","x","1","x","1"," ","2","x","J","x",
				"x","b"," ","3"," "," "," ","1","a","x",
				"x","x","2","x","i","x","x"," ","1","x",
				"x","r","a","J"," ","x","a","x"," ","x",
				"x","x","I","x"," ","I","d"," ","2","x",
				"x","a","1","x","h","1"," ","x","1","x",
				"x","r","d","x"," ","x","x","1","a","x",
				"x","x","x","x","x","x","x","x","x","x"

		};
	}
}

四、怪物集合

我们把怪物放在一个集合里面

下面展示一些 内联代码片

package com.yc.opp3.hc0701;

public class Monsters {
	static Monster m1 = new Monster("绿色史莱姆",50,20,1,1,1);
	static Monster m2 = new Monster("红色史莱姆",50,20,8,2,1);
	static Monster m3 = new Monster("小蝙蝠",60,25,15,3,3);
	static Monster m4 = new Monster("初级魔法师",100,30,10,4,4);
	static Monster m5 = new Monster("骷髅人",70,70,0,5,5);
	static Monster m6 = new Monster("大蝙蝠",120,50,30,6,6);
	
	public static Monster[] ms = new Monster[] {m1,m2,m3,m4,m5,m6};
}

五、游戏类

	游戏类用来对英雄进行操作,开始游戏,创建地图,英雄的移动,遇到不同的对象执行的不同操作。

下面展示一些 内联代码片

package com.yc.opp3.hc0701;

import java.util.Scanner;

public class Game {
	public Hero hero;
	public int  mindex = 1;
	public int hindex = 74;
	public boolean isGameOver = false;
	public Scanner sc = new Scanner(System.in);
	
	public void startGame() {
		hero = new Hero(); // 实例化对象
		//创建地图 显示地图
		createMap(mindex);
		
		System.out.println("\n开始游戏");
		System.out.println(hero.toString());
		System.out.println("请按wsad键进行移动:");
		
		//开始游戏 ,移动勇士
		while(!isGameOver) {
			String chiose = sc.nextLine();
			//开始移动,无视大小写
			
			if("w".equalsIgnoreCase(chiose)) {
				walk(-10);
			}else if ("s".equalsIgnoreCase(chiose)) {
				walk(10);
			}else if("a".equalsIgnoreCase(chiose)) {
				walk(-1);
			}else {
				walk(1);
			}
		}
	}
	private void createMap(int mindex) {
		// TODO Auto-generated method stub
		String[] maps = Maps.maps[mindex -1];
		 for (int i = 0; i < maps.length; i++) {
			System.out.print(maps[i] + " ");
			//10个换行
			if((i + 1) %10 == 0) 
				System.out.println();
			
		}
	}
	//移动
	public void walk(int step) {
		//移动过程中遇到不同对象的判断
		//碰到墙壁禁止移动
		if("x".equals(Maps.maps[mindex-1][hindex + step])) {
			System.out.println();
			createMap(mindex);
			return;
		}
		//红血瓶
		else if("r".equals(Maps.maps[mindex-1][hindex + step])) {
			System.out.println("勇士获得红血瓶,血量+100!");
			hero.setBlood(hero.getBlood() + 100);
			System.out.println(hero.toString());
		}
		
		//蓝血瓶
		else if("r".equals(Maps.maps[mindex-1][hindex + step])) {
			System.out.println("勇士获得蓝血瓶,血量+500!");
			hero.setBlood(hero.getBlood() + 500);
			System.out.println(hero.toString());
		}
		//攻击力
		else if("a".equals(Maps.maps[mindex-1][hindex + step])) {
			System.out.println("勇士获得红宝石,攻击力+3!");
			hero.setAtt(hero.getAtt() + 3);
			System.out.println(hero.toString());
		}
		//防御力
		else if("d".equals(Maps.maps[mindex-1][hindex + step])) {
			System.out.println("勇士获得蓝宝石,防御力+3!");
			hero.setDef(hero.getDef()+3);
			System.out.println(hero.toString());
		}
		//黄钥匙
		else if("i".equals(Maps.maps[mindex-1][hindex + step])) {
			System.out.println("勇士获得黄钥匙!");
			hero.setyKey(hero.getyKey()+1);
			System.out.println(hero.toString());
		}
		//红钥匙
		else if("j".equals(Maps.maps[mindex-1][hindex + step])) {
			System.out.println("勇士获得红钥匙!");
			hero.setrKey(hero.getrKey()+1);
			System.out.println(hero.toString());	
		}
		//蓝钥匙
		else if("k".equals(Maps.maps[mindex-1][hindex + step])) {
			System.out.println("勇士获得蓝钥匙!");
			hero.setbKey(hero.getbKey()+1);			
			System.out.println(hero.toString());
		}
		//开门
		else if ("I".equals(Maps.maps[mindex-1][hindex + step])) {
			System.out.println("勇士遇到了黄门,是否开门?Y/N");
			String op = sc.nextLine();
			if("n".equalsIgnoreCase(op)) {
				//不开门,不移动,显示地图
				createMap(mindex);
				return;
			}
			
			//开门判断是否有钥匙
			
			if(hero.getyKey()<=0) {
				System.out.println("钥匙不足,不可开门!");
				createMap(mindex);
				return;
			}
			//开门,钥匙-1
			
			hero.setyKey(hero.getyKey() - 1);
			System.out.println("黄门开启,黄钥匙 - 1");
			System.out.println(hero.toString());
		}
		//红色
		else if ("J".equals(Maps.maps[mindex-1][hindex + step])) {
			System.out.println("勇士遇到了红门,是否开门?Y/N");
			String op = sc.nextLine();
			if("n".equalsIgnoreCase(op)) {

			String op = sc.nextLine();
			if("n".equalsIgnoreCase(op)) {
				//不开门,不移动,显示地图
				createMap(mindex);
				return;
			}
			
			//开门判断是否有钥匙
			
			if(hero.getbKey()<=0) {
				System.out.println("钥匙不足,不可开门!");
				createMap(mindex);
				return;
			}
			//开门,钥匙-1
			
			hero.setbKey(hero.getbKey() - 1);
			System.out.println("蓝门开启,蓝钥匙 - 1");
			System.out.println(hero.toString());
		}
		else if(" ".equals(Maps.maps[mindex-1][hindex + step])) {
		//空格不管
		}else {
		//剩下的全是数字
		String strNum = Maps.maps[mindex - 1][hindex + step];
		int mNum = Integer.parseInt(strNum);
		System.out.println("遇到怪物:" + Monsters.ms[mNum - 1].toString());
		
		fight(mNum);
		}
		
		
		//移动前位置置空,移动后的位置标记位h
		Maps.maps[mindex - 1][hindex] = " ";
		Maps.maps[mindex - 1][hindex +step ] = "h";
		//改变英雄坐标
		hindex += step;
		
		//重新显示地图
		System.out.println();
		createMap(mindex);
	}
	
	//战斗
	public void fight(int mNum) {
		//先获得原始数据对象
		Monster om =  Monsters.ms[mNum - 1];
		//原始数据不能改变,所以每次战斗都要重新实例化一个对象
		Monster m = new Monster(om.getName(), om.getBlood(), om.getAtt(), om.getDef(), om.getGold(), om.getExp());

				return;
			}
			
		}while(hero.getBlood() < 0 && m.getBlood() > 0); 
		System.out.println(hero.toString());
	}
}

六、测试类,进行游戏的测试

下面展示一些 内联代码片

package com.yc.opp3.hc0701;

public class Test {
	public static void main(String[] args) {
		Game g = new Game();
		g.startGame();
	}
}

这就是一个简单的魔塔案例,是对于类与对象的简单运用。
