简单的实现了下NGUI的上下翻页。有两个接口&＃xff0c;分别是上一页和下一页。

用法如下。

如上图&＃xff0c;第一个参数为 Page的宽或高&＃xff0c;具体由你的滑动组件设定的方向定。

第二个参数为滑动系数&＃xff0c;即&＃xff0c;滑动了多远就翻页

第三个参数为总页数。

依赖组件。UIScrollView&＃xff0c;UICenterOnChild。

脚本和Scroll一起

分页父物体绑上居中脚本。为Scroll的子物体

这个基本功能没问题。但是有一个小缺陷。就是Panel的坐标必须为中心点。如果需要位移需要再加一个父物体。让滑动组件依赖的Panel的相对坐标都为0.

原因是因为我用的坐标去计算的当前页。大家如果有空。可以改为偏移量就能解决这问题。

因为我也用不上这个。这个是写给学员参考的。所以就懒得改了。大家需要的改的话。可以自行修改。

最后。上脚本。
