简易指南针地图条

简单来说就是Scroll View里的Text往复循环，贴吧看到有人问闲着无聊就试一下

层次结构

Scroll Rect

Content挂上GridLayoutGroup，方便自动调整位置大小等

public class StripMap : MonoBehaviour

        m_HorizontalScollBar.value += Input.GetAxis("Mouse X") / 20;

        Transform Celltransform;
        if (locPos >= (StripMapWidth + Segment) / 2)
        {
            Celltransform = GlgTransfrom.GetChild(0); // 将第一个放到末尾
            Celltransform.SetSiblingIndex(3);
