前言：最 近闲来无事，而且也是因为刚接触安卓不久，所以萌生了以后在开发web 项目的过程中同样开发安卓手游，因前一段时间项目需要独立完成了一款功能型手机app ，该App比较简单，全是按钮操作，也就是Activity之间的相互传值与过渡，所以对安卓的基本知识有了一定了解，在我的印象当中，感觉安卓手游是比 较困难的，但是有困难就要克服，所以有了开发游戏的念头。

接着上一篇文章，框架搭建出来之后，我们把代码写一下：

以下是：框架：

飞机大战项目结构

按照思路先把Root代码写出来：

package com.pm_road.fireair.bean;
/**
?*
?* @ClassName: Root
?* @Description: 所有实体类的父类
?* @author liPeng
?* @date 2014-11-5 上午10:20:19
?*
?*/
public class Root {
?? ?
?? ?protected float x;// 位置x
?? ?protected float y;// 位置y
?? ?protected int srcPic;// 图标指向
?? ?
?? ?public float getX() {
?? ??? ?return x;
?? ?}
?? ?public void setX(float x) {
?? ??? ?this.x = x;
?? ?}
?? ?public float getY() {
?? ??? ?return y;
?? ?}
?? ?public void setY(float y) {
?? ??? ?this.y = y;
?? ?}
?? ?public int getSrcPic() {
?? ??? ?return srcPic;
?? ?}
?? ?public void setSrcPic(int srcPic) {
?? ??? ?this.srcPic = srcPic;
?? ?}
?
}

然后把飞机的实体类代码写出来：

package com.pm_road.fireair.bean;

/**
?*
?* @ClassName: Plane
?* @Description: 飞机
?* @author lipeng
?* @date 2014-11-5 上午10:03:50
?*
?*/
public class Plane extends Root {

?? ?protected int life;// 生命
?? ?protected boolean shot;// 是否发射

?? ?public int getLife() {
?? ??? ?return life;
?? ?}

?? ?public void setLife(int life) {
?? ??? ?this.life = life;
?? ?}

?? ?public boolean isShot() {
?? ??? ?return shot;
?? ?}

?? ?public void setShot(boolean shot) {
?? ??? ?this.shot = shot;
?? ?}
}

接下来是你控制的飞机（实体类里没有任何代码，主要原因是继承的原因，写这样一个实体类，主要原因是用于区别敌机）：

package com.pm_road.fireair.bean;
/**
?* 控制的战机
?* @ClassName: YourPlane
?* @Description: 你的战机,继承飞机
?* @author lipeng
?* @date 2014-11-5 上午10:21:02
?*
?*/
public class YourPlane extends Plane{
?? ?
?? ?
}

?

敌机实体类代码：（里面也没有任何代码，主要原因是继承了plane，区别你控制的飞机）

?

package com.pm_road.fireair.bean;
/**
?*
?* @ClassName: EnemyPlane
?* @Description: 敌机
?* @author lipeng
?* @date 2014-11-5 上午10:22:57
?*
?*/
public class EnemyPlane extends Plane{

}

?

飞机的子弹实体类：

package com.pm_road.fireair.bean;
/**
?*
?* @ClassName: Bullet
?* @Description: 子弹
?* @author liPeng
?* @date 2014-11-5 上午10:24:48
?*
?*/
public class Bullet extends Root{
?? ?
?? ?private boolean fly;//是否飞行

?? ?public boolean isFly() {
?? ??? ?return fly;
?? ?}

?? ?public void setFly(boolean fly) {
?? ??? ?this.fly = fly;
?? ?}
?? ?
?? ?
}

实体类写完之后：我们开始写相应的线程代码：首先是PlaneRunnable 线程，而在此线程中：飞机会发射子弹，在发射子弹的时候，会再起一个子弹线程BulletRunnable

package com.pm_road.fireair.thread;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff.Mode;
import android.util.Log;
import android.view.SurfaceHolder;
import android.widget.ImageButton;

import com.pm_road.fireair.bean.Bullet;
import com.pm_road.fireair.bean.Plane;
import com.pm_road.fireair.common.CommonUtil;

/**
?* 飞机线程
?*
?* @ClassName: PlaneThread
?* @Description: 飞机线程
?* @author lipeng
?* @date 2014-11-5 上午10:27:40
?*
?*/
public class PlaneRunnable implements Runnable {

?? ?private Plane plane;// 此线程中的飞机

?? ?private Context context;// 上下文

?? ?private SurfaceHolder holder;

?? ?private ImageButton planeImg;// 飞机的图片
?? ?
?? ?private int planeHalfWidth;//飞机宽度一半，美化射击效果
?? ?/**
?? ? * 构造方法
?? ? *
?? ? * @param context
?? ? */
?? ?public PlaneRunnable(Context context, SurfaceHolder holder) {
?? ??? ?super();
?? ??? ?this.context = context;
?? ??? ?this.holder = holder;
?? ?}

?? ?@Override
?? ?public void run() {

?? ??? ?
?? ??? ?Canvas canvas = null;
?? ??? ?while (plane.isShot()) {

?? ??? ??? ?canvas = holder.lockCanvas();
?? ??? ??? ?canvas.drawColor(Color.TRANSPARENT, Mode.CLEAR);

?? ??? ??? ?Paint paint = new Paint();
?? ??? ??? ?paint.setColor(Color.BLUE);
?? ??? ??? ?Log.i(CommonUtil.THREAD_TAG, plane.getX()+”:”+plane.getY());
?? ??? ??? ?canvas.drawText(CommonUtil.BULLET, plane.getX() + planeHalfWidth, plane.getY(), paint);

?? ??? ??? ?holder.unlockCanvasAndPost(canvas);
?? ??? ??? ?//发射一个子弹
?? ??? ??? ?shotOneBullet();
?? ??? ??? ?Log.i(CommonUtil.THREAD_TAG, “plane射击状态为true”);

?? ??? ??? ?try {
?? ??? ??? ??? ?Thread.sleep(200);
?? ??? ??? ?} catch (InterruptedException e) {
?? ??? ??? ??? ?e.printStackTrace();
?? ??? ??? ?}
?? ??? ?}
?? ??? ?Log.i(CommonUtil.THREAD_TAG, “plane停止射击”);
?? ?}
?? ?
?? ?/**
?? ? * 发射一枚子弹
?? ? */
?? ?private void shotOneBullet(){
?? ??? ?
?? ??? ?Bullet bullet = new Bullet();
?? ??? ?bullet.setX(plane.getX()+planeHalfWidth);
?? ??? ?bullet.setY(plane.getY());
?? ??? ?bullet.setFly(true);//飞行中
?? ??? ?
?? ??? ?BulletRunnable bulletRunnable = new BulletRunnable(context,holder);
?? ??? ?//子弹装进线程
?? ??? ?bulletRunnable.setBullet(bullet);
?? ??? ?//子弹开始飞行
?? ??? ?new Thread(bulletRunnable).start();
?? ?}
?? ?
?? ?public Plane getPlane() {
?? ??? ?return plane;
?? ?}

?? ?public void setPlane(Plane plane) {
?? ??? ?this.plane = plane;
?? ?}

?? ?public ImageButton getPlaneImg() {
?? ??? ?return planeImg;
?? ?}

?? ?public void setPlaneImg(ImageButton planeImg) {
?? ??? ?this.planeImg = planeImg;
?? ??? ?planeHalfWidth = planeImg.getWidth() / 2;
?? ?}

}

下面是BulletRunnable 的代码：，为了美化一个效果，所以当子弹没有碰到任何东西，飞出屏幕边界的时候，在屏幕边缘要进行爆炸，爆炸线程：BoomRunnable

package com.pm_road.fireair.thread;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff.Mode;
import android.util.Log;
import android.view.SurfaceHolder;

import com.pm_road.fireair.bean.Bullet;
import com.pm_road.fireair.common.CommonUtil;

/**
?* 子弹线程
?*
?* @ClassName: BulletRunnable
?* @Description: 子弹线程
?* @author lipeng
?* @date 2014-11-5 上午10:33:19
?*
?*/
public class BulletRunnable implements Runnable {

?? ?private Bullet bullet;//当前的子弹
?? ?
?? ?private Context context;//上下文
?? ?
?? ?private SurfaceHolder holder;
?? ?
?? ?public BulletRunnable(Context context,SurfaceHolder holder) {
?? ??? ?super();
?? ??? ?this.context = context;
?? ??? ?this.holder = holder;
?? ?}

?? ?@Override
?? ?public void run() {
?? ??? ?
?? ??? ?Canvas canvas = null;
?? ??? ?while(bullet.isFly()){
?? ??? ??? ?
?? ??? ??? ?canvas = holder.lockCanvas();
?? ??? ??? ?canvas.drawColor(Color.TRANSPARENT, Mode.CLEAR);

?? ??? ??? ?Paint paint = new Paint();
?? ??? ??? ?paint.setColor(Color.BLUE);
?? ??? ??? ?canvas.drawText(CommonUtil.BULLET, bullet.getX(), bullet.getY()-70, paint);

?? ??? ??? ?holder.unlockCanvasAndPost(canvas);

?? ??? ??? ?try {
?? ??? ??? ??? ?Thread.sleep(200);
?? ??? ??? ?} catch (InterruptedException e) {
?? ??? ??? ??? ?e.printStackTrace();
?? ??? ??? ?}
?? ??? ??? ?bullet.setY(bullet.getY() -70);
?? ??? ??? ?if(bullet.getY() <= 0){
?? ??? ??? ??? ?//如果当前线程的Y超过了屏幕，则将该线程回收
?? ??? ??? ??? ?bullet.setFly(false);
?? ??? ??? ??? ?//爆炸效果
?? ??? ??? ??? ?boom();
?? ??? ??? ??? ?break;
?? ??? ??? ?}
?? ??? ??? ?try {
?? ??? ??? ??? ?Thread.sleep(100);
?? ??? ??? ?} catch (InterruptedException e) {
?? ??? ??? ??? ?e.printStackTrace();
?? ??? ??? ?}
?? ??? ??? ?Log.i(CommonUtil.THREAD_TAG, “子弹飞行中”);
?? ??? ?}
?? ??? ?Log.i(CommonUtil.THREAD_TAG, “子弹线程结束”);
?? ?}
?? ?
?? ?/**
?? ? * 爆炸效果
?? ? */
?? ?private void boom(){
?? ??? ?
?? ??? ?//声明爆炸效果
?? ??? ?BoomRunnable boomRunnable = new BoomRunnable(context, holder);
?? ??? ?boomRunnable.setBullet(bullet);
?? ??? ?//爆炸
?? ??? ?new Thread(boomRunnable).start();
?? ?}
?? ?
?? ?public Bullet getBullet() {
?? ??? ?return bullet;
?? ?}

?? ?public void setBullet(Bullet bullet) {
?? ??? ?this.bullet = bullet;
?? ?}

}

以下是爆炸线程：BoomRunnable，该爆炸线程暂时没有调用图片，只是用几根线勾勒出一个简单效果 ，后期继续增加：

package com.pm_road.fireair.thread;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff.Mode;
import android.view.SurfaceHolder;

import com.pm_road.fireair.bean.Bullet;

/**
?* 爆炸线程
?*
?* @ClassName: BoomRunnable
?* @Description: 爆炸线程
?* @author lipeng
?* @date 2014-11-5 下午02:43:39
?*
?*/
public class BoomRunnable implements Runnable {

?? ?private Bullet bullet;// 当前的子弹
?? ?
?? ?private Context context;// 上下文
?? ?
?? ?private SurfaceHolder holder;
?? ?
?? ?
?? ?public BoomRunnable(Context context,SurfaceHolder holder) {
?? ??? ?super();
?? ??? ?this.context = context ;
?? ??? ?this.holder = holder;
?? ?}

?? ?@Override
?? ?public void run() {
?? ??? ?
?? ??? ?Canvas canvas = holder.lockCanvas();
?? ??? ?canvas.drawColor(Color.TRANSPARENT, Mode.CLEAR);
?? ??? ?
?? ??? ?Paint paint = new Paint();
?? ??? ?paint.setColor(Color.BLUE);
?? ??? ?//碰撞效果
?? ??? ?canvas.drawLine(bullet.getX()-10, 2, bullet.getX()-15, 10, paint);
?? ??? ?canvas.drawLine(bullet.getX()-15, 10, bullet.getX()-10, 12, paint);
?? ??? ?canvas.drawLine(bullet.getX()-10, 12, bullet.getX()-13, 20, paint);
?? ??? ?canvas.drawLine(bullet.getX()-13, 20, bullet.getX(), 12, paint);
?? ??? ?canvas.drawLine(bullet.getX(), 12, bullet.getX()+13, 20, paint);
?? ??? ?canvas.drawLine(bullet.getX()+13, 20, bullet.getX()+10, 12, paint);
?? ??? ?canvas.drawLine(bullet.getX()+10, 12, bullet.getX()+15, 10, paint);
?? ??? ?canvas.drawLine(bullet.getX()+15, 10, bullet.getX()+10, 2, paint);
?? ??? ?holder.unlockCanvasAndPost(canvas);
?? ?}

?? ?public Bullet getBullet() {
?? ??? ?return bullet;
?? ?}

?? ?public void setBullet(Bullet bullet) {
?? ??? ?this.bullet = bullet;
?? ?}
?? ?
?? ?
}

写完实体类和线程之后，就应该把他和安卓的xml 进行结合。结合代码：http://www.pm-road.com/index.php/2014/11/06/161/
