Java Ball.setAllFirst示例

  private void shipCrash(Ball ball) {

    ArrayList<Integer> lr = getPointListUp(ball.getRadio(), ball.getXC(), ball.getYC());
    int r2 = (int) Math.pow(ball.getRadio(), 2);

    if (lr.contains(r2) && ball.getDY() >= 0) {
      ball.setDY(ball.getDY() * -1);
      ball.setAllFirst();
    }
  }
