Question

我尝试开发一个具有球位图和方形位图的游戏应用程序。方形位图从下向上滚动，球从上到下下降。

我想写一个代码来碰撞两个位图（球和方形）

任何人都可以帮助我..

private void doDraw(Canvas c) {
/*  int width = c.getWidth();
    int height = c.getHeight();
    c.drawRect(0, 0, width, height, backgroundPaint); */


     Bitmap ball = BitmapFactory.decodeResource(getResources(),R.drawable.ball); //Load a ball image.
     ballH=ball.getHeight();
      ballW=ball.getWidth();
     Bitmap kangoo = BitmapFactory.decodeResource(getResources(),R.drawable.b);
  sh=kangoo.getHeight();

      sw=(kangoo.getWidth());
      ballX = (int) (mScrWidth /2) - (ballW / 2) ; //Centre ball X into the centre of the screen.
        ballY = -50; //Centre ball height above the screen.
 c.drawColor(Color.WHITE);

c.drawBitmap（kangoo，-10，vall - ，null）; c.drawBitmap（kangoo，（sw），vall - ，null）;

    synchronized (model.LOCK) {
        ballX = model.ballPixelX;
        ballY = model.ballPixelY;


    }

    //c.drawBitmap(ball, ballX,ballY, ballPaint);
     c.drawBitmap(kangoo,-10, vall2--, null);
     c.drawBitmap(kangoo,(sw), vall2--, null);
     c.drawBitmap(kangoo,-10, vall3--, null);
     c.drawBitmap(kangoo, (sw), vall3--, null);

}

这是我的代码.. 除碰撞外，一切都完美无缺。这两个物体只是交叉..
