在执行简单的《Pong》AI时，我们会创建两个摇杆并闪烁

所以，我是一个新程序员，而不是做实际的人工智能执行，我使用以下解决方案，使球拍在右边跟着球:

if(ball.position.Y > p2.position.Y)
{
    p2.position.Y += ball.position.Y;
}
else if (ball.position.Y < p2.position.Y)
{
    p2.position.Y -= ball.position.Y;
}

然而，这种情况发生(好吧，我试着用PrtScn截取屏幕截图，它似乎暂停游戏一微秒，捕捉一个桨而不是两个闪烁的桨)我怎么做才能让两个桨看起来像一个呢?
