Unity 利用grid layout group实现页数切换

 int _int_PageIndex=0;//页下标
    int _int_SinglePageQuantityr = 6;//每页数量
    int _int_PageCount = 1;//总页数,下标0开始,1就是共2页
    /// <summary>
    /// 翻页 -1或1
    /// </summary>
    /// <param name="leftOrRight"></param>
    private void PageRefresh(int leftOrRight)
    {
    
    
        _int_PageIndex += leftOrRight;
        _int_PageIndex = Mathf.Clamp(_int_PageIndex, 0,1); //限制页数 0 1
        Debug.Log("当前是第"+_int_PageIndex+1+"页");//第一页下标是0
        int temp_CloseItemNumber = _int_PageIndex * _int_SinglePageQuantityr;
        for (int i = 0; i < _trans_ItemParent.childCount; i++)//_trans_ItemParent 所有item的父物体
        {
    
    
            GameObject temp_item = _trans_ItemParent.GetChild(i).gameObject;
            if (temp_CloseItemNumber > i)  _trans_ItemParent.GetChild(i).gameObject.SetActive(false);
            else  _trans_ItemParent.GetChild(i).gameObject.SetActive(true); 
        }
    }
