用两天时间试着用JAVA模拟植物大战僵尸写的游戏
程序只用了2天时间完成，BUG较多，也没有做过多优化，功能也很简单，最后也没有想去改进
源代码免费提供，CSDN上的需要积分下载，可以去GIT上下载**
GIT地址：/akh5/JAVA/tree/master/Plants
只有当左下角图标亮起时才能安放豌豆射手
主要代码
父类MovingObject，包含所有判断和图片读取相关代码
package Plants;import java.awt.Graphics;import java.awt.image.BufferedImage;import java.util.Random;public abstract class MovingObject {public static final int LIFE = 0;public static final int DEAD = 1;public static final int REMOVE = 2;public static final int EAT = 3 ;public static final int HIT = 4;protected int state = LIFE ;//当前状态（默认为活着）protected int width; //宽protected int height; //高protected int x; //横坐标protected int y; //纵坐标/*僵尸，植物的构造方法*/public MovingObject(int width,int height) {this.width = width;this.height = height;}public MovingObject(int width , int height , int x , int y){this.width = width;this.height = height;this.x = x;this.y = y;}public abstract void step();//获取对象的图片public abstract BufferedImage getImage();//判断对象是否是活着public boolean isLife() {return state == LIFE ; //当前状态为LIFE 表示对象活着}//判断对象是否是死着public boolean isDead() {return state == DEAD ; //当前状态为LIFE 表示对象活着}//判断对象是否删除public boolean isRemove() {return state == REMOVE ; //当前状态为LIFE 表示对象活着}public boolean isEat(){return state == EAT;}public boolean isHit(){return state == HIT ;}public boolean outofBounds() {return this.y>=World.HEIGHT;}public void paintObject(Graphics g) {g.drawImage(this.getImage(), this.x,this.y,null);}// /*判断敌人是否越界*/// public boolean outofBounds() {// //return this.y>=World.HEIGHT;// }/*碰撞检测 this是敌人 other是子弹*/public boolean hit(MovingObject other) {int x1 = this.x-other.width; //int x2 = this.x+this.width; //int y1 = this.y-other.height;int y2 = this.y+this.height;int x = other.x;int y = other.y;//x在x1与x2之间，且y在y1与y2之间，即为撞上了return x>=x1&&x<=x2&&y>=y1&&y<=y2;}public void goDead() {state = DEAD; //将当前状态修改为DEAD}public void goEat(){state = EAT;}public void goHit(){state = HIT;}}
图片Image类，存放图片路径
这里用切换图片的方法让图片动起来，植物和僵尸有十几张按帧截出来图，循环切换图片达到动图效果
package Plants;import java.awt.image.BufferedImage;import javax.imageio.ImageIO;import java.io.IOException;public class Images {public static BufferedImage background; //背景图public static BufferedImage bullets; //子弹图public static BufferedImage[] sun; //太阳图public static BufferedImage[] plants; //植物切换public static BufferedImage[] zombies; //僵尸public static BufferedImage select0; //背景图public static BufferedImage select1;public static BufferedImage[] eat;public static BufferedImage[] die;public static BufferedImage start;public static BufferedImage gameover;public static BufferedImage sunback;static{background = readImage("background.png");bullets = readImage("bullet.png");sun = new BufferedImage[10];for(int i = 0; i< 10;i++){sun[i] = readImage("Sun"+i+".png");}select0 = readImage("select0.png");select1 = readImage("select1.png");sunback = readImage("SunBack.png");eat = new BufferedImage[4];for(int i = 0;i<4;i++){eat[i] = readImage("eat"+i+".png");}start = readImage("start.png");gameover = readImage("gameover.png");die = new BufferedImage[3];for (int i = 0; i<3;i++){die[i] = readImage("die"+i+".png");}plants = new BufferedImage[13];for(int i = 0;i<13;i++){plants[i] = readImage("Peashooter["+(i+1)+"].png");}zombies = new BufferedImage[18];for(int i = 0 ;i<18;i++){zombies[i] = readImage("Zombie["+(i+1)+"].png");}}public static BufferedImage readImage(String fileName){//同包下读取图片try {BufferedImage img = ImageIO.read(MovingObject.class.getResource(fileName));return img;}catch(Exception e){e.printStackTrace();throw new RuntimeException();}}}
子类Plant，豌豆射手图片切换，以及图片宽高，坐标
package Plants;import java.awt.image.BufferedImage;public class Plants extends MovingObject {private int life;private int getx;private int gety;public int moveable = 1;private int timer = 0;public Plants(int x,int y){super(90,90,x,y);life = 3;}@Overridepublic void step() {}int index = 5;@Overridepublic BufferedImage getImage() {// 每十毫秒走一次if(isLife()) {BufferedImage img = Images.plants[index++%13];//System.out.println(index);return img;}if(isDead()) {return null;}return null;/* index = 0;* 10M 返回Images.heros[0] index = 1* 20M 返回Images.heros[1] index = 2* 30M 返回Images.heros[0] index = 3* 40M 返回Images.heros[1] index = 4* */}public void subtaractLife() {if(timer++%2 == 0)life--;if(life<0){goDead();state =REMOVE;}}}
子类Zombies，效果同Plants
package Plants;import java.awt.image.BufferedImage;import java.util.Random;public class Zombies extends MovingObject {private int speed;private int timer = 0;private int life = 3;public Zombies(int getx,int gety) {super(100, 120,getx,gety);speed = 2;}@Overridepublic void step() {if(!isEat()&&timer<50)x-=speed;if (timer>50)x-=speed;}int index = 0;@Overridepublic BufferedImage getImage() {if(isLife()) {return Images.zombies[index++%18];}if(isEat()&&timer++<50){return Images.eat[index++%4];}if(timer>=50){state = LIFE;}if(isLife()) {return Images.zombies[index++%4];}if(isDead()){int i = 0;state = REMOVE;return Images.die[i++];// state = REMOVE;// return img;}return null; //删除状态，直接返回NULL；}}
子类back，背景图
package Plants;import java.awt.Graphics;import java.awt.image.BufferedImage;public class Back extends MovingObject {public Back() {super(World.WIDTH, World.HEIGHT, 0, 0);}@Overridepublic void step() {}@Overridepublic BufferedImage getImage() {return Images.background;}public void paintObject(Graphics g) {g.drawImage(this.getImage(), this.x, this.y, null);}}
子类Sun
package Plants;import java.awt.image.BufferedImage;import java.util.Random;public class Sun extends MovingObject {public Sun(int x,int y) {super(100,100,x,y);Random rand = new Random();x = rand.nextInt(World.WIDTH-this.width);}@Overridepublic void step() {y+=3;}int index = 0;@Overridepublic BufferedImage getImage() {return Images.sun[index++%9];}}
主类World，主要代码，全部功能的实现类，僵尸入场，鼠标监听，这里只设定了鼠标点击操作，判定当前太阳值，能否安防豌豆射手。用数组方式存放所有对象，动态扩容

音乐Music类，单线程播放背景音乐。
package Plants;import java.io.BufferedInputStream;import java.io.FileInputStream;import java.io.FileNotFoundException;import javazoom.jl.decoder.JavaLayerException;import javazoom.jl.player.Player;public class Music extends Thread {public void run() {try {FileInputStream fil1 =new FileInputStream("src/Plants/Music/Crazy Davy.mp3");BufferedInputStream bis1 =new BufferedInputStream(fil1);Player p = new Player(bis1);p.play();} catch (FileNotFoundException e) {e.printStackTrace();} catch (JavaLayerException e) {e.printStackTrace();}}}
数据库相关操作次要功能
package Plants;import java.sql.Connection;import java.sql.DriverManager;import java.sql.ResultSet;import java.sql.SQLException;import java.sql.Statement;public class UserDao {//1定义数据库驱动public static String driver="com.mysql.jdbc.Driver" ;//定义urlpublic static String url="jdbc:mysql://localhost:3306/shoot";//定义mysql用户名，每个人的用户在安装mysql的时候是自己定义的public static String user="root";//定义mysql设置是的密码static String password="";//定义连接对象Connectionpublic static Connection con;//定义传输器对象public static Statement statement;public static void DBConnection() throws Exception {//注册数据库Class.forName(driver);//获取数据库连接con=DriverManager.getConnection(url, user, password);//获取传输器statement=con.createStatement();//}//将分数存入数据库public static void save(String name,int score) throws Exception {try {DBConnection();String sql="insert into score(username,score) values('"+name+"',"+score+")";//利用传输器将sql传入数据库statement.executeUpdate(sql);} catch (Exception e) {// TODO 自动生成的 catch 块e.printStackTrace();}finally {con.close();}}public static String[] getScoreAndUsername() throws Exception {ResultSet rs = null;String result[] = new String[100];try {DBConnection();String sql="select username,score from score order by score desc";rs = statement.executeQuery(sql);for (int i = 0 ;i<result.length;i++) {if(rs.next()) {result[i] = "第"+(i+1)+"名"+rs.getString("username")+":"+rs.getInt("score");}}} catch (Exception e) {// TODO 自动生成的 catch 块e.printStackTrace();}finally {con.close();rs.close();}return result;}public static void main(String[] args) throws Exception {String result[] = getScoreAndUsername();for(int i = 0;i<result.length;i++) {if(result[i]!=null) {System.out.println(result[i]);}}}}
简单实现的程序，其中的功能和算法也相对粗糙
BUG也很多，比如没有设置豌豆射手的安放区域，所以豌豆射手是鼠标点哪放哪的，以及子弹的生成也是通过鼠标点击的同时生成的，而且是单线程的操作，所以只能用一次点击鼠标完成操作。
僵尸设定了生命值，但是还是被子弹一碰就死，这里要修改父类godie（）相关代码，但是后续不想更新了所以没有修改。
我在僵尸死的时候设定了一组轮播的图片，但是僵尸还是死后一秒直接消失，这里是数组成员REMOVE操作一旦执行就把当前僵尸的元素删除了，所以可以在子弹触碰和删除前延时操作。
