我的雷电游戏（重力感应控制）

    算是第一个写的比较满意的游戏吧，肯定还有很多很多不足，希望高手能指点下，呵。现在在看图灵出版的一本android游戏的书籍，有点难，涉及底层有点多，都是JNI、NDK、linux shell脚本等，主要是将怎么将c（++）平台的游戏移植到android平台下。啥时候俺能移植了就牛X了。

游戏总介：

重力感应，480*320分辨率，设计为3关，没用到游戏引擎，含有开始界面（开始、退出、声音、说明），游戏情节设计花费了很长时间，想尽量做到每一关都不同，游戏介绍：

 

游戏素材：玩家——中国歼十战斗机，敌机——日本二战期间飞机（自己PS了半天）；

敌机种类：1.向玩家飞机移动

        2.随机个数、随机路径（8种）移动

        3.只向Y方向移动，模拟碉堡，散弹，打掉后出现换子弹精灵（2上子弹、3上子弹、5上子弹、螺旋向上子弹）；

加血设定：设定加血精灵，每关出现由加血精灵排列而成的C、H、E、n、S、H、I、q、I、A、n、g的字母(ChenShiqiang)即为加血的，每一个加血精灵与玩家碰撞玩家血值加一，满100玩家生命数加一，生命数<=5；

关卡设定：每一关背景图片、背景音乐、敌机出现的频率、敌机生命值、敌机路径、boss生命值、加血字母出现频率、boss出现时间等设置不同，以boss死亡为通关标志（boss出现到死亡期间以vibrator模拟心跳效果），每一关通过都显示得分界面再进入下一关；

 

为了便于修改，屏幕分辨率、背景滚动的速度、GameView刷新频率、飞行路径等静态常量都放一个工具类里面。

游戏模块介绍：

重力感应控制：

SensorManager mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);

Sensor mSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION);

注册：

mRegistedSensor = mSensorManager.registerListener(MainActivity.this, mSensor, SensorManager.SENSOR_DELAY_GAME);

取消注册：

if(mRegistedSensor)

{

      mSensorManager.unregisterListener(this);

      mRegistedSensor = false;

}

控制：（倾斜角度为ConstantUtil.accuracy有效）

 public void onSensorChanged(SensorEvent event) { if(event.sensor.getType()==Sensor.TYPE_ORIENTATION) { float ay = event.values[1];//正前负后 float az = event.values[2];//正左负右 if(ay>ConstantUtil.accuracy) { action = action | ConstantUtil.dir_up; Log.i("plane", "up "+ay+" "+az); } if(ay<-ConstantUtil.accuracy) { action = action | ConstantUtil.dir_down; Log.i("plane", "down "+ay+" "+az); } if(az>ConstantUtil.accuracy) { action = action | ConstantUtil.dir_left; Log.i("plane", "left "+ay+" "+az); } if(az<-ConstantUtil.accuracy) { action = action | ConstantUtil.dir_right; Log.i("plane", "right "+ay+" "+az); } if(ay<=ConstantUtil.accuracy & ay>=-ConstantUtil.accuracy & az<=ConstantUtil.accuracy & az>=-ConstantUtil.accuracy) { action = ConstantUtil.horizon; } } }

心跳效果：

Vibrator vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);

long[] pattern = {800, 40,400, 30}; // OFF/ON/OFF/ON...

vibrator.vibrate(pattern, 2);//-1不重复，非-1为从pattern的指定下标开始重复

取消：

if(null!=vibrator)

{

       vibrator.cancel();

}

界面切换：在Activity的onCreate方法里定义一个Handler来接受界面变换消息。

myhandler = new Handler() { public void handleMessage(android.os.Message msg) { switch(msg.what) { case 0://游戏失败 ContentView = null; System.gc(); ContentView = new FailView(MainActivity.this,MainActivity.this); setContentView(ContentView); break; case 1://进入第一关 ContentView = null; System.gc(); ContentView = new GameView(MainActivity.this, MainActivity.this, 1); setContentView(ContentView); mRegistedSensor = mSensorManager.registerListener(MainActivity.this, mSensor, SensorManager.SENSOR_DELAY_GAME); Log.i("plane", "mRegistedSensor "+mRegistedSensor); break; case 2://进入第二关 ContentView = null; System.gc(); ContentView = new GameView(MainActivity.this, MainActivity.this, 2); setContentView(ContentView); mRegistedSensor = mSensorManager.registerListener(MainActivity.this, mSensor, SensorManager.SENSOR_DELAY_GAME); break; case 3://进入第三关 ContentView = null; System.gc(); ContentView = new GameView(MainActivity.this, MainActivity.this, 3); setContentView(ContentView); mRegistedSensor = mSensorManager.registerListener(MainActivity.this, mSensor, SensorManager.SENSOR_DELAY_GAME); break; case 10://第一关结束 if(null!=vibrator){ vibrator.cancel(); } ContentView = null; System.gc(); ContentView = new LevelView(MainActivity.this, 1, msg.arg1, MainActivity.this); setContentView(ContentView); break; case 20://第二关结束 if(null!=vibrator){ vibrator.cancel(); } ContentView = null; System.gc(); ContentView = new LevelView(MainActivity.this, 2, msg.arg1, MainActivity.this); setContentView(ContentView); break; case 30://第三关结束 if(null!=vibrator){ vibrator.cancel(); } ContentView = null; System.gc(); ContentView = new LevelView(MainActivity.this, 3, msg.arg1, MainActivity.this); setContentView(ContentView); break; case 4://心跳效果 vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE); long[] pattern = {800, 40,400, 30}; // OFF/ON/OFF/ON... vibrator.vibrate(pattern, 2);//-1不重复，非-1为从pattern的指定下标开始重复 break; case 5://欢迎，重新开始 ContentView = null; System.gc(); ContentView = new WelcomeView(MainActivity.this,MainActivity.this); setContentView(ContentView); break; default: break; } }; };

游戏声音：

背景音乐用MediaPlayer，

游戏各种音效用SoundPool（小容量（<1M），多个音频同时播放）

 背景图片绘制：

int hight1 = 0;

int hight2 = -ConstantUtil.screenheight;

int w = ConstantUtil.screenweith;

int h = ConstantUtil.screenheight;

 

//背景循环显示，在GameView的Draw()方法里，不断刷新移动

Rect rectsrc = new Rect(0, 0, w, h);

Rect rectdst1 = new Rect(0, hight1, w, h+hight1);

Rect rectdst2 = new Rect(0, hight2, w, h+hight2);

canvas.drawBitmap(background, rectsrc, rectdst1, null);

canvas.drawBitmap(background, rectsrc, rectdst2, null);

hight1+=ConstantUtil.bgspan;

hight2+=ConstantUtil.bgspan;

if(hight1>h)

{

   hight1=-h;

}

if(hight2>h)

{

   hight2=-h;

}

碰撞检测：

//判断两个矩形是否碰撞，根据矩形重叠来判断

   private boolean isContain(int otherX, int otherY, int otherWidth, int otherHeight){//判断两个矩形是否碰撞

      int xd = 0;//大的x

      int yd = 0;//大大y

      int xx = 0;//小的x

      int yx = 0;//小的y

      int width = 0;

      int height = 0;

      boolean xFlag = true;//玩家飞机x是否在前

      boolean yFlag = true;//玩家飞机y是否在前

      if(this.x >= otherX){

        xd = this.x;

        xx = otherX;

        xFlag = false;

      }else{

        xd = otherX;

        xx = this.x;

        xFlag = true;

      }

      if(this.y >= otherY){

        yd = this.y;

        yx = otherY;

        yFlag = false;

      }else{

        yd = otherY;

        yx = this.y;

        yFlag = true;

      }

      if(xFlag == true){

        width = this.bitmap.getWidth();

      }else {

        width = otherWidth;

      }

      if(yFlag == true){

        height = this.bitmap.getHeight();

      }else{

        height = otherHeight;

      }

      if(xd>=xx&&xd<=xx+width-1&&

           yd>=yx&&yd<=yx+height-1){//首先判断两个矩形有否重叠

          double Dwidth=width-xd+xx;   //重叠区域宽度   

        double Dheight=height-yd+yx; //重叠区域高度

        if(Dwidth*Dheight/(otherWidth*otherHeight)>=0.20){//重叠面积超20%则判定为碰撞

           return true;

        }

      }

      return false;

   } 

 

例：判断玩家是否与敌机碰撞

public boolean contain(EnemyPlane ep)   //敌机

   {

      if(isContain(ep.x, ep.y, ep.bitmap.getWidth(), ep.bitmap.getHeight()))

      {//检测成功

        blood-=20;//自己的生命减20

        return true;

      }

      return false;

   }

 

子弹类：构造函数里包含x位置, y位置, 子弹的类型,图片type, 子弹方向dir，以构造所有子弹

public class Bullet { int x,y;//子弹的坐标 int srcx,srcy; int dir;//子弹的方向,0静止，1上,2右上，3右，4右下，5下，6左下，7左，8左上,9左斜上，10右斜上,11旋转向上，12旋转向下 int type;//子弹的类型,图片 Bitmap bitmap;//当前子弹的图片 GameView gameView;//gameView的引用 int moveSpan = 15;//移动的像素 private boolean isAlive = true;//是否显示 int arcPathCount = 0; public Bullet(int x, int y, int type, int dir,GameView gameView) { this.x = x; this.y = y; this.srcx = x; this.srcy = y; this.type = type; this.dir = dir; this.gameView = gameView; initBitmap(); } public void initBitmap() { if(type == 1){//当类型为1时 bitmap = BitmapFactory.decodeResource(gameView.getResources(), R.drawable.mybullet1); } else if(type == 2){//类型为2时 bitmap = BitmapFactory.decodeResource(gameView.getResources(), R.drawable.mybullet2); } else if(type == 3){//类型为3时 bitmap = BitmapFactory.decodeResource(gameView.getResources(), R.drawable.mybullet3); } else if(type == 4){//类型为4时 bitmap = BitmapFactory.decodeResource(gameView.getResources(), R.drawable.ebullet1); } else if(type == 5){//类型为5时 bitmap = BitmapFactory.decodeResource(gameView.getResources(), R.drawable.ebullet2); } else if(type == 6){//类型为6时 bitmap = BitmapFactory.decodeResource(gameView.getResources(), R.drawable.ebullet3); } else if(type == 7){//类型为7时 bitmap = BitmapFactory.decodeResource(gameView.getResources(), R.drawable.ebullet4); } else if(type == 8){//类型为8时 bitmap = BitmapFactory.decodeResource(gameView.getResources(), R.drawable.bossbullet); } else if(type == 9){//类型为9时 bitmap = BitmapFactory.decodeResource(gameView.getResources(), R.drawable.bossbullet2); } } public void draw(Canvas canvas)//绘制的方法 { canvas.drawBitmap(bitmap, x, y,null); } public void move()//移动的方法 { if(dir == 3){//向右移动 x += moveSpan; } if(dir == 7){//向左移动 x -= moveSpan; } if(dir == 1){//向上移动 y -= moveSpan; } if(dir == 5){//向下移动 y += moveSpan; } if(dir == 6){//向左下移动 x -= moveSpan; y += moveSpan; } if(dir == 8){//向左上移动 x -= moveSpan; y -= moveSpan; } if(dir == 2){//右上移动 x += moveSpan; y -= moveSpan; } if(dir == 4){//右下移动 x += moveSpan; y += moveSpan; } if(dir == 9){//左斜上移动 y -= moveSpan; x -=moveSpan/2; } if(dir == 10){//右斜上移动 y -= moveSpan; x +=moveSpan/2; } if(dir == 11){//旋转移动 if(arcPathCount==24) arcPathCount=0; x=(int) (srcx+ConstantUtil.arcpath[0][arcPathCount]); y=(int) (y-ConstantUtil.arcpath[1][arcPathCount]); arcPathCount++; } if(dir == 12){//旋转移动 if(arcPathCount==24) arcPathCount=0; x=(int) (srcx+ConstantUtil.arcpath[0][arcPathCount]); y=(int) (y+ConstantUtil.arcpath[1][arcPathCount]); arcPathCount++; } if(x<-20 | x>ConstantUtil.screenweith+20 | y<0 | y>ConstantUtil.screenheight) { this.setAlive(false); } } public boolean isAlive() { return isAlive; } public void setAlive(boolean isAlive) { this.isAlive = isAlive; } }

 

螺旋子弹实现：定义一段路径，轨迹片段通过sin(x)实现。想了半天，似乎没有回旋的函数，只能这样了。

public static double[][] arcpath =

{     {Math.sin(Math.PI/16)*50,Math.sin(Math.PI*2/16)*50,Math.sin(Math.PI*3/16)*50,Math.sin(Math.PI*4/16)*50,Math.sin(Math.PI*5/16)*50,Math.sin(Math.PI*6/16)*50,Math.sin(Math.PI*7/16)*50,Math.sin(Math.PI*8/16)*50,Math.sin(Math.PI*9/16)*50,Math.sin(Math.PI*10/16)*50,Math.sin(Math.PI*11/16)*50,Math.sin(Math.PI*12/16)*50,Math.sin(Math.PI*13/16)*50,Math.sin(Math.PI*14/16)*50,Math.sin(Math.PI*15/16)*50,Math.sin(Math.PI*16/16)*50,Math.sin(Math.PI*18/16)*50,Math.sin(Math.PI*20/16)*50,Math.sin(Math.PI*22/16)*50,Math.sin(Math.PI*24/16)*50,Math.sin(Math.PI*26/16)*50,Math.sin(Math.PI*28/16)*50,Math.sin(Math.PI*30/16)*50,Math.sin(Math.PI*32/16)*50},

   {10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,-10,-10,-10,-10,-10,-10,-10,-10},

};

 

加血模块：思路是定义各个字母数组以存储各个加血精灵的位置，到指定时间生成字母加血精灵组，然后整体向下移动。

敌机随机路径实现：定义数组存储路径，数组中存放路径中每个“站点”的步数，生成第二种敌机时可指定敌机从第几点开始移动。

//飞行路径

   public static int[][] pathA =         //右左

   {  

      {-120,-80, -40,   0, 320, -30},//路径中每个点的X坐标

      {-10, 0 ,  30,  30, 200, 350},//路径中每个点的Y坐标

      {7  , 7 ,   7,  40,  40,   0},//路径中两点间的步数

   };

  

   public static int[][] pathB =         //左右

   {

      {420,400, 360, 320, -20, 350},//路径中每个点的X坐标

      {-10,0 ,  15,  30, 200, 350},//路径中每个点的Y坐标

      {7  , 7 ,   7,  40,  40,   0},//路径中两点间的步数

   };

  

   public static int[][] pathC =         //左

   {

      {420,400, 360, 320, -20},//路径中每个点的X坐标

      {-10, 0 ,  15,  30, 450},//路径中每个点的Y坐标

      {7  , 7 ,   7,  80,  0},//路径中两点间的步数

   };

  

   public static int[][] pathD =         //右

   {

      {-50 ,-40, -30, -20, 320},//路径中每个点的X坐标

      {-10 , 0 ,  15,  30, 450},//路径中每个点的Y坐标

      {7   , 7 ,  7 ,  80,  0 },//路径中两点间的步数

   };

  

   public static int[][] pathE =         //右左右

   {  

      {-100,-80, -40,   0, 320, -30 ,320},//路径中每个点的X坐标

      { -10 ,0 ,  30,  30, 245, 245 ,400},//路径中每个点的Y坐标

      { 7   ,7 ,   7,  40,  40,  40 , 0 },//路径中两点间的步数

   };

  

   public static int[][] pathF =         //左右左

   {  

      {400 ,360, 340,  320, -20, 320 ,-20},//路径中每个点的X坐标

      {-10 , 0 ,  30,   30, 245, 245 ,400},//路径中每个点的Y坐标

      {7   , 7 ,   7,  40,  40,   40 , 0 },//路径中两点间的步数

   };

 

在敌机EnemyPlane构造函数中有指定第几种敌机、指定路径和路径中起始点的参数。
