最近玩  超级玛丽，地图上的 花草都会摇摆，很是有趣。

于是我用来模仿一下。摇摆和伸展 的设计。

这个是  同一个 方向摇摆的。

这个是不同方向摇摆的。

代码设计很简单，开放了两个参数接口，就是摆动和拉伸的 幅度。

                //正常转
                if (zhuan_zhengfanqiehuan % 2 == 0)
                {

                else

                    zhuan_dongleiji += zhuan_dongspeed;
                }
                yidonglasheng_zongshen++;

                    yidonglasheng_zongshen = 0;
                }
    
                if (yidonglasheng_zhengfanqiehuan % 2 == 0)
                {
                    vec.y += yidonglasheng_dongspeed;
                    vecs.y += yidonglasheng_dongspeed;
                }
                else
                {
                    vec.y -= yidonglasheng_dongspeed;
                    vecs.y -= yidonglasheng_dongspeed;
                }
                transform.position = vec;
                transform.localScale = vecs;
                rotations.eulerAngles = new Vector3(0.0f, 0.0f, 500 * zhuan_dongleiji);
                transform.rotation = rotations;
            }
        }
    }

这里面最关键的一点就是，图片 中心点，必须 调整到  下方。
