## 简单弹球游戏 ##

**一.小游戏功能描述**  
功能一：进入小游戏界面，点击play,游戏开始，点击exit可继续上一局游戏。  
功能二：小球和球拍分别以圆形区域和矩形区域代替，小球开始以随机速度向下运动，遇到上方的障碍或下方的球拍时小球反弹，球拍由用户控制，球拍按左右键时，球拍会左右移动。  
功能三：若没有接住球，游戏失败，则屏幕显示goodbye。

**二.过程及重要代码**  
1.定义屏幕、球拍、球、障碍并设置属性

//屏幕宽高
        int screenWidth = 0;
        int screenHeight = 0;
    
        //障碍挡板宽
        public int baffleWith;
        //每份宽
        int perWidth = 0;
        //间隔宽
        int InterWidth = 0;
    
        //每份高
        int perHeight = 0;
        //间隔高
        int InterHeight = 0;
    
        //挡板层数
        public int baffleLev = 8;
        //每层挡板数
        public int baffleNum = 5;
        //挡板颜色
        public int[] colors = {
        Color.BLUE, Color.RED, Color.GREEN, Color.YELLOW, Color.BLUE, Color.RED, Color.GREEN, Color.YELLOW};
        //挡板总数
        public int baffleTotle = baffleLev * baffleNum;
    
        //障碍物X坐标
        int  baffleX [] = null;
        //障碍物Y坐标
        int baffleY [] = null;
        //障碍物标签
        int baffleArr[][] = null;

/**画障碍物*/
        public void drawBaffle(Canvas canvas){
        
            //屏幕宽高
            screenWidth = screenWidth != 0 ? screenWidth : MainActivity.tableWidth;
            screenHeight = screenHeight != 0 ? screenHeight: MainActivity.tableHeight;
    
            //宽
            perWidth = perWidth != 0 ? perWidth : screenWidth/(baffleNum+2);
            //间隔宽
            InterWidth = InterWidth != 0 ? InterWidth : perWidth*2/(baffleNum+1);
    
            int tempLev = baffleLev/2;
            //每份高
            perHeight = perHeight != 0 ? perHeight :  screenHeight/2/(colors.length+tempLev+2);
            //间隔高
            InterHeight = InterHeight !=0 ? InterHeight : perHeight/2;
    
            int tempHeight = 0;
            int tempH = 0;
            int tempWidht = 0;
            int tempW = 0;

//屏幕宽
        public static int tableWidth;
        //屏幕高
        public static int tableHeight;
        //常亮属性
        PowerManager powerManager = null;
        WakeLock wakeLock = null;
    
        MediaPlayer media = null;
    
    
    @Override
        protected void onCreate(Bundle savedInstanceState) {
        
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
     //设置常亮
        this.powerManager = (PowerManager)this.getSystemService(Context.POWER_SERVICE);
        this.wakeLock = this.powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK, "My Lock");
    
        //获取窗口管理器
        WindowManager  windowManager = getWindowManager();
        Display display = windowManager.getDefaultDisplay();
        DisplayMetrics metrics = new DisplayMetrics();
        display.getMetrics(metrics);
        //获取屏幕宽和高
        tableWidth = metrics.widthPixels;
        tableHeight = metrics.heightPixels;

2.设置按钮属性

//按钮宽和高
        int botwidth = (int) ((int) tableWidth/2.5);
        int botheight = (int) ((int) tableHeight/8);
    
        //设置play
        ImageButton playbot =(ImageButton) findViewById(R.id.play);
        ViewGroup.LayoutParams playbotn = (ViewGroup.LayoutParams) playbot.getLayoutParams();
        playbotn.width = botwidth;
        playbotn.height = botheight;
    
        playbot.setOnClickListener(new OnClickListener() {
        
    
            @Override
            public void onClick(View source) {
        
                Intent intent = new Intent(MainActivity.this, PlayActivity.class);
                startActivity(intent);
            }
        });
    
        //设置 exit
        ImageButton exitbot =(ImageButton) findViewById(R.id.exit);
        ViewGroup.LayoutParams exitbotn = (ViewGroup.LayoutParams) exitbot.getLayoutParams();
        exitbotn.width = botwidth;
        exitbotn.height = botheight;

3.设置游戏

final Timer timer = new Timer();
            timer.schedule(new TimerTask() {
        
    
                @Override
                public void run() {
        
                    //结束判断
                    if( (playView.circleY + playView.radius) > (playView.paiY + playView.paiHeight) ){
        
                        timer.cancel();
                        playView.isOver = true;
                    }else{
        
                        //碰到墙壁时X的改变
                        if( playView.circleX <= playView.radius
                                || playView.circleX >= playView.screenWidth - playView.radius ){
        
                            playView.speedX = -playView.speedX;
                        }
                        //碰到墙壁时Y的改变
                        if( playView.circleY <= playView.radius
                                || ( playView.circleX >= playView.paiX
                                && playView.circleX <= (playView.paiX + playView.paiWidth)
                                && (playView.circleY + playView.radius) >= playView.paiY
                                && (playView.circleY + playView.radius) <= playView.paiY + playView.paiHeight)  ){
        
                            playView.speedY = -playView.speedY;
                        }
    
                        //初始化后才判断
                        if( playView.baffleX != null ){
        
                            //碰到障碍时X的改变
                            for( int i = 0; i < playView.baffleLev; i++ ){
        
                                int tag = 0;
                                if( playView.circleY >= playView.baffleY[i]
