簡易彈球游戲

簡單彈球游戲

一.小游戲功能描述
功能一：進入小游戲界面，點擊play,游戲開始，點擊exit可繼續上一局游戲，
功能二：小球和球拍分別以圓形區域和矩形區域代替，小球開始以隨機速度向下運動，遇到上方的障礙或下方的球拍時小球反彈，球拍由用戶控制，球拍按左右鍵時，球拍會左右移動，
功能三：若沒有接住球，游戲失敗，則螢屏顯示goodbye，

二.程序及重要代碼
1.定義螢屏、球拍、球、障礙并設定屬性

//螢屏寬高
    int screenWidth = 0;
    int screenHeight = 0;

    //障礙擋板寬
    public int baffleWith;
    //每份寬
    int perWidth = 0;
    //間隔寬
    int InterWidth = 0;

    //每份高
    int perHeight = 0;
    //間隔高
    int InterHeight = 0;

    //擋板層數
    public int baffleLev = 8;
    //每層擋板數
    public int baffleNum = 5;
    //擋板顏色
    public int[] colors = {Color.BLUE, Color.RED, Color.GREEN, Color.YELLOW, Color.BLUE, Color.RED, Color.GREEN, Color.YELLOW};
    //擋板總數
    public int baffleTotle = baffleLev * baffleNum;

    //障礙物X坐標
    int  baffleX [] = null;
    //障礙物Y坐標
    int baffleY [] = null;
    //障礙物標簽
    int baffleArr[][] = null;

 /**畫障礙物*/
    public void drawBaffle(Canvas canvas){
        //螢屏寬高
        screenWidth = screenWidth != 0 ? screenWidth : MainActivity.tableWidth;
        screenHeight = screenHeight != 0 ? screenHeight: MainActivity.tableHeight;

        //寬
        perWidth = perWidth != 0 ? perWidth : screenWidth/(baffleNum+2);
        //間隔寬
        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);
        //間隔高
        InterHeight = InterHeight !=0 ? InterHeight : perHeight/2;

        int tempHeight = 0;
        int tempH = 0;
        int tempWidht = 0;
        int tempW = 0;

 //螢屏寬
    public static int tableWidth;
    //螢屏高
    public static int tableHeight;
    //常亮屬性
    PowerManager powerManager = null;
    WakeLock wakeLock = null;

    MediaPlayer media = null;


@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

 //設定常亮
    this.powerManager = (PowerManager)this.getSystemService(Context.POWER_SERVICE);
    this.wakeLock = this.powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK, "My Lock");

    //獲取視窗管理器
    WindowManager  windowManager = getWindowManager();
    Display display = windowManager.getDefaultDisplay();
    DisplayMetrics metrics = new DisplayMetrics();
    display.getMetrics(metrics);
    //獲取螢屏寬和高
    tableWidth = metrics.widthPixels;
    tableHeight = metrics.heightPixels;

2.設定按鈕屬性

 //按鈕寬和高
    int botwidth = (int) ((int) tableWidth/2.5);
    int botheight = (int) ((int) tableHeight/8);

    //設定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);
        }
    });

    //設定 exit
    ImageButton exitbot =(ImageButton) findViewById(R.id.exit);
    ViewGroup.LayoutParams exitbotn = (ViewGroup.LayoutParams) exitbot.getLayoutParams();
    exitbotn.width = botwidth;
    exitbotn.height = botheight;

3.設定游戲

 final Timer timer = new Timer();
        timer.schedule(new TimerTask() {

            @Override
            public void run() {
                //結束判斷
                if( (playView.circleY + playView.radius) > (playView.paiY + playView.paiHeight) ){
                    timer.cancel();
                    playView.isOver = true;
                }else{
                    //碰到墻壁時X的改變
                    if( playView.circleX <= playView.radius
                            || playView.circleX >= playView.screenWidth - playView.radius ){
                        playView.speedX = -playView.speedX;
                    }
                    //碰到墻壁時Y的改變
                    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;
                    }

                    //初始化后才判斷
                    if( playView.baffleX != null ){
                        //碰到障礙時X的改變
                        for( int i = 0; i < playView.baffleLev; i++ ){
                            int tag = 0;
                            if( playView.circleY >= playView.baffleY[i]

                                                && playView.circleX <= (playView.baffleX[j] + playView.perWidth + playView.radius) ){
                                            playView.speedX = -playView.speedX;

                                            tag = 1;
                                            break;

                                if( tag == 1 ) break;
                            }

                        //碰到障礙時Y的改變
