所有类的父类FlyingObject
概括所有对象的共性，统一调用
import java.awt.Image;//父类（英雄机，小敌机，小蜜蜂，子弹）public abstract class FlyingObject {//抽象方法必须为抽象类int x,y; //定位int width,height; //对象宽度和高度Image image; //定义图像//让每一个子类移动的方法----------------------------------------------------------------------------------public abstract void step(); //由于每个子类的移动方法不一样，定为抽象方法//判断子弹是否与敌人相撞方法-------------------------------------------------------------------------------public boolean hitBy(Bullet bullet) {int x = bullet.x; //子弹x 坐标int y = bullet.y;return x>this.x && x<this.x+this.width&&y>this.y && y<this.y+height; //子弹与敌人相撞的临界状态}}
英雄机Hero类
主要包括英雄机出现位置，英雄机大小，生命值，火力值的设置算法；英雄机发射子弹算法；英雄机与敌机相撞判定算法；英雄机打到小蜜蜂的奖励算法。
import java.awt.Image;//英雄机public class Hero extends FlyingObject{int life; //英雄机生命int doubleFire; //英雄机火力值0/1Image[] images = {}; //图片数组（两张图片切换动画）public Hero() {image = ShootGame.hero0; //使用第一张英雄机图片width = image.getWidth(null); //获得英雄机宽度height = image.getHeight(null); //获得英雄机宽度x = 150; //英雄机初始高度宽度y = 450;life = 3; //初始生命doubleFire = 0; //开始英雄机单倍火力images =new Image[] {ShootGame.hero0,ShootGame.hero1}; //两张图片}int index = 0;//实现抽象父类中对象移动的方法@Overridepublic void step() {// TODO Auto-generated method stubimage = images[index++/10%images.length];//图片数组切换，形成英雄机动画，最后赋值给image}//发射子弹的方法------------------------------------------------------------------------------------------public Bullet[] shoot() {Bullet[] bs = {}; //子弹数组，初值为空if(doubleFire ==0) {//单倍火力bs = new Bullet[1];bs[0] = new Bullet( x+width/2-4,y-14); //一颗子弹的坐标计算}else {//双倍火力bs =new Bullet[2];bs[0] = new Bullet(x+width/4-4,y-14); //英雄机的宽度1/4-子弹宽度的一半bs[1] = new Bullet(x+width*3/4-4,y-14);doubleFire -= 2;}return bs;}//获取得分------------------------------------------------------------------------------------------------public int getScore() {return 5;}//增加火力------------------------------------------------------------------------------------------------public void addDoubleFire() {doubleFire +=40;}//增加生命------------------------------------------------------------------------------------------------public void addLife() {life += 1;}//判断英雄机是否与敌人相撞方法-----------------------------------------------------------------------------public boolean duang(FlyingObject f) {int x = this.x;int y = this.y; //获得英雄机当前位置int x1 = f.x - this.width; //敌人x坐标-英雄机宽度int x2 = f.x + f.width; //敌人x坐标+敌人宽度int y1 = f.y - this.height; //敌人y坐标-英雄机高度int y2 = f.y + f.height; //敌人y坐标+敌人高度return x>x1 && x<x2&&y>y1 && y<y2; //临介条件}}
小敌机Airplane类
设置小敌机出现位置，移动限制
//小敌机public class Airplane extends FlyingObject {int ySpeed; //向下速度public Airplane() {image = ShootGame.airplane; //小敌机图片width = image.getWidth(null); //小敌机宽度height = image.getHeight(null); //小敌机高度x = (int) (Math.random()*ShootGame.width); //小敌机出现x坐标，背景屏幕宽度y = -height; //小敌机的y坐标ySpeed = 1; //向下移动速度}//实现抽象父类中对象移动的方法-----------------------------------------------------------------------------@Overridepublic void step() {// TODO Auto-generated method stuby += ySpeed; //一次递增一个速度}}
小蜜蜂Bee类
小蜜蜂奖励算法；小蜜蜂出现算法；
//小蜜蜂public class Bee extends FlyingObject{int ySpeed;//向下速度int xSpeed;//左右速度int awardType;public Bee() {image = ShootGame.bee; //调用小蜜蜂图片width = image.getWidth(null); //获取图片宽度height = image.getHeight(null); //获取图片高度x = (int) (Math.random()*ShootGame.width); //小蜜蜂x坐标（随机进入）y = -height; //小蜜蜂高度，设为窗体下方，方便提前看到小蜜蜂xSpeed = 1; //小蜜蜂x轴方向速度ySpeed = 1; //小蜜蜂y轴方向速度awardType = (int) (Math.random()*2); //得分(随机性)}//实现抽象父类中对象移动的方法-----------------------------------------------------------------------------@Overridepublic void step() {// TODO Auto-generated method stuby += ySpeed;x += xSpeed;if(x > ShootGame.width - width) {//大于屏幕宽度-x宽度小蜜蜂大于右边界xSpeed =-1;}if(x<=0) {xSpeed = 1; //小蜜蜂移动至左边界，向右移动}}//获取得分方法--------------------------------------------------------------------------------------------public int getAwardType() {return awardType;}}
子弹Bullet类
包括对发射子弹初始化，子弹移动的设置
//子弹public class Bullet extends FlyingObject{int ySpeed; //子弹向下速度public Bullet(int x,int y) {image = ShootGame.bullet; //调用子弹图片width = image.getWidth(null); //获得子弹宽度height = image.getHeight(null); //获得子弹高度this.x = x; //子弹实时坐标（随英雄机变换）this.y = y;ySpeed = 3;}//实现抽象父类中对象移动的方法@Overridepublic void step() {// TODO Auto-generated method stuby -= ySpeed;}}## 游戏规则```java飞机大战游戏规则（游戏需求）通过鼠标点击游戏Start界面开始游戏；鼠标控制英雄机移动；父类FlyingObject（提取共同属性，制作父类）属性x,ywidth,heightimg小敌机Airplane属性x,y（定位其位置）width,height（定义图片高度宽度）img（图片属性）ySpeed=1（只能上下移动，下移速度为1）小蜜蜂Bee属性x,y（定位其位置）width,height（定义图片高度宽度）img（图片属性）ySpeed=1（可以上下移动，下移速度为1）XSpeed（可以左右移动）awardType（被打到时奖励0/1分）0：奖励单倍火力1：奖励双倍火力（随机性）英雄机（随鼠标移动）属性x,y（定位其位置）width,height（定义图片高度宽度）img（图片属性）life(生命值)doubleFire（火力值）0：发射一个子弹1：发射两个子弹行为发射子弹，鼠标移动子弹属性x,y（定位其位置）width,height（定义图片高度宽度）img（图片属性）ySpeed（只能上移）
游戏基础人物构造图片
图片需要统一放在image文件夹中，方便调用。image文件放入创建的Java项目包下。
