通过左右两边按键控制图片轮播。

public class Lunbo : MonoBehaviour
{
   
    public RectTransform[] tfs;    //需要扩展只需往该数组添加Item即可
    public void LeftBtnClickEvent()//左边按键
    {
        for (int i = 0; i < tfs.Length - 1; i++)
        {
            tfs[i+1].DOAnchorPos(tfs[i].anchoredPosition, 0.2f);//第i+1个元素移动至第i个元素的位置
            tfs[i+1].DOSizeDelta(tfs[i].sizeDelta, 0.2f);
        }
        tfs[0].DOAnchorPos(tfs[tfs.Length-1].anchoredPosition, 0.2f);
        tfs[0].DOSizeDelta(tfs[tfs.Length - 1].sizeDelta, 0.2f);
    }
    public void RightBtnClickEvent()//右边按键
    {
        for (int i = tfs.Length - 1; i >0; i--)
        {
            tfs[i -1].DOAnchorPos(tfs[i].anchoredPosition, 0.2f);
            tfs[i -1].DOSizeDelta(tfs[i].sizeDelta, 0.2f);
        }
        tfs[tfs.Length - 1].DOAnchorPos(tfs[0].anchoredPosition, 0.2f);
        tfs[tfs.Length - 1].DOSizeDelta(tfs[0].sizeDelta, 0.2f);
    }
}

 将左右两边的按键与代码中相应的函数绑定即可
