项目02《游戏-09-开发》Unity3D-编程知识

基于项目02《游戏-08-开发》Unity3D ，

本次任务是做抽卡界面，获取的卡片增添在背包中，并在背包中可以删除卡片，

首先在Canvas下创建一个空物体，命名为LotteryPanel，作为抽卡界面，

在右上角的锚点处设置为拉伸模式，这样他的宽高就变成1920 * 1080，

首先给这个界面添加一个关闭按钮，

十连抽按键，

ctrl + d 复制一份按钮改为单抽，

然后创建一个Image子物体命名为LotteryItem并复制十份，

拖拽星级预制体，

修改位置，

添加颜色，

然后将其余9个LotteryItem删除，重新复制到10个，

再创建一个文件夹Lottery用来存放关于抽卡的预制体，

此时我们已经有了两个界面，一个是抽卡界面，一个是背包界面，

为了将这个两个界面联系起来，再做个主界面，

接下来调整位置，

添加好主界面之后，找到MainGame.cs脚本进行修改：

在PackageLocalData.cs脚本中增添方法：

using System.Collections.Generic;
using UnityEngine;
public class PackageLocalData{
static PackageLocalData _instance;
public static PackageLocalData Instance{
get{
if (_instance == null)
_instance = new PackageLocalData();
return _instance;
}
}
//存
public List<PackageLocalItem> items;
public void SavaPackage(){
string inventoryJson = JsonUtility.ToJson(this);
PlayerPrefs.SetString("PackageLocalData", inventoryJson);
PlayerPrefs.Save();
}
//取
public List<PackageLocalItem> LoadPackage(){
if (items != null)
return items;
if (PlayerPrefs.HasKey("PackageLocalData")){
string inventoryJson = PlayerPrefs.GetString("PackageLocalData");
PackageLocalData packageLocalData = JsonUtility.FromJson<PackageLocalData>(inventoryJson);
items = packageLocalData.items;
return items;
}
else{
items = new List<PackageLocalItem>();
return items;
}
}
//添加抽卡阶段
public void SavePackage(){
string inventoryJson = JsonUtility.ToJson(this);
PlayerPrefs.SetString("PackageLocalData", inventoryJson);
PlayerPrefs.Save();
}
}
[System.Serializable]
public class PackageLocalItem{
public string uid;
public int id;
public int num;
public int level;
public bool isNew;
public override string ToString(){
return string.Format($"[id] {id} [num] {num}");
}
}

using System.Collections.Generic;
using System.Runtime.InteropServices.WindowsRuntime;
using UnityEngine;
using static UIManager;
public class MainGame : MonoBehaviour{
public static Player player;
void Awake(){
player = GameObject.Find("Player").GetComponent<Player>();
//背包系统
_instance = this;
DontDestroyOnLoad(gameObject);
}
//背包系统
static MainGame _instance;
PackageTable packageTable;
public static MainGame Instance{
get{
return _instance;
}
}
void Start(){
//UIManager.Instance.OpenPanel(UIConst.PackagePanel);
}
//对静态数据加载
public PackageTable GetPackageTable(){
if (packageTable == null)
packageTable = Resources.Load<PackageTable>("TableData/PackageTable");
return packageTable;
}

//对动态数据加载
public List<PackageLocalItem> GetPackageLocalData(){
return PackageLocalData.Instance.LoadPackage();
}
//根据ID去表格中拿到指定的数据
public PackageTableItem GetPackageItemById(int id){
List<PackageTableItem> packageDataList = GetPackageTable().dataList;
foreach (PackageTableItem item in packageDataList){
if (item.id == id)
return item;
}
return null;
}
//根据uid去本地数据中拿到动态数据
public PackageLocalItem GetPackageLocalItemByUId(string uid){
List<PackageLocalItem> packageDataList = GetPackageLocalData();
foreach (PackageLocalItem item in packageDataList){
if (item.uid == uid)
return item;
}
return null;
}
public List<PackageLocalItem> GetSortPackageLocalData(){
List<PackageLocalItem> localItems = PackageLocalData.Instance.LoadPackage();
localItems.Sort(new PackageItemComparer());//添加
return localItems;
}
public class PackageItemComparer : IComparer<PackageLocalItem>{
public int Compare(PackageLocalItem a, PackageLocalItem b){
PackageTableItem x = MainGame.Instance.GetPackageItemById(a.id);
PackageTableItem y = MainGame.Instance.GetPackageItemById(b.id);
//首先按star从大到小排序
int starComparison = y.star.CompareTo(x.star);
//如果star相同，则按id从大到小排序
if (starComparison == 0){
int idComparison = y.id.CompareTo(x.id);
if (idComparison == 0)
return b.level.CompareTo(a.level);
return idComparison;
}
return starComparison;
}
}

//添加抽卡阶段字段
public class GameConst {
//武器类型
public const int PackageTypeWeapon = 1;
//食物类型
public const int PackageTypeFood = 2;
}
//添加抽卡阶段
//根据类型获取配置的表格数据
public List<PackageTableItem> GetPackageTableByType(int type){
List<PackageTableItem> packageItems = new List<PackageTableItem>();
foreach (PackageTableItem packageItem in GetPackageTable().dataList){
if (packageItem.type == type)
packageItems.Add(packageItem);
}
return packageItems;
}
//添加抽卡阶段具体逻辑随机抽卡，获得一件武器
public PackageLocalItem GetLotteryRandom1(){
List<PackageTableItem> packageItems = GetPackageTableByType(GameConst.PackageTypeWeapon);
int index = Random.Range(0, packageItems.Count);
PackageTableItem packageItem = packageItems[index];
PackageLocalItem packageLocalItem = new(){
uid = System.Guid.NewGuid().ToString(),
id = packageItem.id,
num = 1,
level = 1,
isNew = CheckWeaponIsNew(packageItem.id),
};
PackageLocalData.Instance.items.Add(packageLocalItem);
PackageLocalData.Instance.SavePackage();
return packageLocalItem;
}
public bool CheckWeaponIsNew(int id) {
foreach (PackageLocalItem packageLocalItem in GetPackageLocalData()) {
if (packageLocalItem.id == id)
return false;
}
return true;
}
//随机抽卡十连抽
public List<PackageLocalItem> GetLotteryRandom10(bool sort = false) {
//随机抽卡
List<PackageLocalItem> packageLocalItems = new();
for (int i = 0; i < 10; i++) {
PackageLocalItem packageLocalItem = GetLotteryRandom1();
packageLocalItems.Add(packageLocalItem);
}
//武器排序
if (sort)
packageLocalItems.Sort(new PackageItemComparer());
return packageLocalItems;
}
}
下一步写整个抽卡界面的代码逻辑：

首先添加一个脚本LotteryPanel.cs

然后绑定脚本，

双击LotteryPanel.cs脚本修改代码：

using UnityEngine;
using UnityEngine.UI;
public class LotteryPanel : BasePanel{
Transform UIClose;
Transform UICenter;
Transform UILottery10;
Transform UILottery1;
GameObject LotteryCellPrefab;
protected override void Awake(){
base.Awake();
InitUI();
InitPrefab();
}
void InitUI() {
UIClose = transform.Find("TopRight/Close");
UICenter = transform.Find("Center");
UILottery10 = transform.Find("Bottom/Lottery10");
UILottery1 = transform.Find("Bottom/Lottery1");
UILottery10.GetComponent<Button>().onClick.AddListener(OnLottert10Btn);
UILottery1.GetComponent<Button>().onClick.AddListener(OnLottert1Btn);

UIClose.GetComponent<Button>().onClick.AddListener (OnClose);
}
void OnClose(){
print(">>>>>>>> OnClose");
}
void OnLottert1Btn(){
print(">>>>>>>> OnLottert1Btn");
}
void OnLottert10Btn(){
print(">>>>>>>> OnLottert10Btn");
}
void InitPrefab() {
LotteryCellPrefab = Resources.Load("Prefab/Panel/Lottery/LotteryItem") as GameObject;
}
}
修改UIManager.cs脚本：

using System.Collections.Generic;
using UnityEngine;
public class UIManager{
static UIManager _instance;
Transform _uiRoot;
//路径配置字典
Dictionary<string, string> pathDict;
//预制体缓存字典
Dictionary<string, GameObject> prefabDict;
//已打开界面的缓存字典
public Dictionary<string, BasePanel> panelDict;
public static UIManager Instance{
get{
if (_instance == null)
_instance = new UIManager();
return _instance;
}
}
public Transform UIRoot{
get{
if (_uiRoot == null){
if (GameObject.Find("Canvas"))
_uiRoot = GameObject.Find("Canvas").transform;
else
_uiRoot = new GameObject("Canvas").transform;
};
return _uiRoot;
}
}
UIManager(){
InitDicts();
}
void InitDicts(){
prefabDict = new Dictionary<string, GameObject>();
panelDict = new Dictionary<string, BasePanel>();
pathDict = new Dictionary<string, string>(){
{ UIConst.PackagePanel,"Package/PackagePanel"},//**
//添加抽卡路径
{ UIConst.LotteryPanel,"Lottery/LotteryPanel"},
};
}
public BasePanel GetPanel(string name){
BasePanel panel = null;
//检查是否已打开
if (panelDict.TryGetValue(name, out panel))
return panel;
return null;
}
public BasePanel OpenPanel(string name){
BasePanel panel = null;
//检查是否已打开
if (panelDict.TryGetValue(name, out panel)){
Debug.Log($"界面已打开 {name}");
return null;
}
//检查路径是否配置
string path = "";
if (!pathDict.TryGetValue(name, out path)){
Debug.Log($"界面名称错误或未配置路径 {name}");
return null;
}
//使用缓存的预制体
GameObject panelPrefab = null;
if (!prefabDict.TryGetValue(name, out panelPrefab)){
string realPath = "Prefabs/Panel/" + path;
panelPrefab = Resources.Load<GameObject>(realPath) as GameObject;
prefabDict.Add(name, panelPrefab);
}
//打开界面
GameObject panelObject = GameObject.Instantiate(panelPrefab, UIRoot, false);
panel = panelObject.GetComponent<BasePanel>();
panelDict.Add(name, panel);
panel.OpenPanel(name);
return panel;
}
//关闭界面
public bool ClosePanel(string name){
BasePanel panel = null;
if (!panelDict.TryGetValue(name, out panel)){
Debug.LogError($"界面未打开 {name}");
return false;
}
panel.ClosePanel();
return true;
}
public class UIConst{
//配置常量
public const string PackagePanel = "PackagePanel";//**
//添加抽卡阶段
public const string LotteryPanel = "LotteryPanel";
}
}
配置完成之后就可以在MainGame.cs脚本中打开这个界面，

运行游戏点击十连抽和单抽就会做出响应，

为了将背包与抽卡界面关联起来，先写主页面脚本，

创建新脚本MainPanel.cs脚本，

绑定脚本，

双击MainPanel.cs修改代码：

using UnityEditor;
using UnityEngine;
using UnityEngine.UI;
public class MainPanel : BasePanel{
Transform UILottery;
Transform UIPackage;
Transform UIQuitBtn;
protected override void Awake(){
base.Awake();
InitUI();
}
void InitUI(){
UILottery = transform.Find("Top/LotteryBtn");
UIPackage = transform.Find("Top/PackageBtn");
UIQuitBtn = transform.Find("BottomLeft/QuitBtn");
UILottery.GetComponent<Button>().onClick.AddListener(OnBtnLottery);
UIPackage.GetComponent<Button>().onClick.AddListener(OnBtnPackage);
UIQuitBtn.GetComponent<Button>().onClick.AddListener(OnQuitGame);
}
void OnQuitGame(){
print(">>>>> OnQuitGame");
EditorApplication.isPlaying = false;
Application.Quit();
}
void OnBtnPackage(){
print(">>>>> OnBtnPackage");
UIManager.Instance.OpenPanel(UIManager.UIConst.PackagePanel);
ClosePanel();
}
void OnBtnLottery(){
print(">>>>> OnBtnLottery");
UIManager.Instance.OpenPanel(UIManager.UIConst.LotteryPanel);
ClosePanel();
}
}
接着修改UIManager.cs脚本：

using System.Collections.Generic;
using UnityEngine;
public class UIManager{
static UIManager _instance;
Transform _uiRoot;
//路径配置字典
Dictionary<string, string> pathDict;
//预制体缓存字典
Dictionary<string, GameObject> prefabDict;
//已打开界面的缓存字典
public Dictionary<string, BasePanel> panelDict;
public static UIManager Instance{
get{
if (_instance == null)
_instance = new UIManager();
return _instance;
}
}
public Transform UIRoot{
get{
if (_uiRoot == null){
if (GameObject.Find("Canvas"))
_uiRoot = GameObject.Find("Canvas").transform;
else
_uiRoot = new GameObject("Canvas").transform;
};
return _uiRoot;
}
}
UIManager(){
InitDicts();
}
void InitDicts(){
prefabDict = new Dictionary<string, GameObject>();
panelDict = new Dictionary<string, BasePanel>();
pathDict = new Dictionary<string, string>(){
{ UIConst.PackagePanel,"Package/PackagePanel"},//**
//添加抽卡路径
{ UIConst.LotteryPanel,"Lottery/LotteryPanel"},
//添加主页面转换路径
{ UIConst.MainPanel,"MainPanel"},
};
}
public BasePanel GetPanel(string name){
BasePanel panel = null;
//检查是否已打开
if (panelDict.TryGetValue(name, out panel))
return panel;
return null;
}
public BasePanel OpenPanel(string name){
BasePanel panel = null;
//检查是否已打开
if (panelDict.TryGetValue(name, out panel)){
Debug.Log($"界面已打开 {name}");
return null;
}
//检查路径是否配置
string path = "";
if (!pathDict.TryGetValue(name, out path)){
Debug.Log($"界面名称错误或未配置路径 {name}");
return null;
}
//使用缓存的预制体
GameObject panelPrefab = null;
if (!prefabDict.TryGetValue(name, out panelPrefab)){
string realPath = "Prefabs/Panel/" + path;
panelPrefab = Resources.Load<GameObject>(realPath) as GameObject;
prefabDict.Add(name, panelPrefab);
}
//打开界面
GameObject panelObject = GameObject.Instantiate(panelPrefab, UIRoot, false);
panel = panelObject.GetComponent<BasePanel>();
panelDict.Add(name, panel);
panel.OpenPanel(name);
return panel;
}
//关闭界面
public bool ClosePanel(string name){
BasePanel panel = null;
if (!panelDict.TryGetValue(name, out panel)){
Debug.LogError($"界面未打开 {name}");
return false;
}
panel.ClosePanel();
return true;
}
public class UIConst{
//配置常量
public const string PackagePanel = "PackagePanel";//**
//添加抽卡阶段
public const string LotteryPanel = "LotteryPanel";
//添加抽卡的主界面阶段
public const string MainPanel = "MainPanel";
}
}
最后修改MainGame.cs脚本：

再修改LotteryPanel.cs脚本：

再修改PackagePanel.cs脚本：

调整资源包位置，

运行游戏即可在背包中进行切换了，

接下来继续修改LotteryPanel.cs脚本：

先不写十连抽函数更重要的是去写更新单抽的逻辑脚本：

首先创建一个脚本LotteryCell.cs脚本，

绑定脚本，

双击LotteryCell.cs修改脚本：

using UnityEngine;
using UnityEngine.UI;
public class LotteryCell : MonoBehaviour{
Transform UIImage;
Transform UIStars;
Transform UINew;
PackageLocalItem packageLocalItem;
PackageTableItem packageTableItem;
LotteryPanel uiParent;
void Awake(){
InitUI();
}
void InitUI(){
UIImage = transform.Find("Center/Image");
UIStars = transform.Find("Bottom/Stars");
UINew = transform.Find("Top/New");
UINew.gameObject.SetActive(false);
}
public void Refresh(PackageLocalItem packageLocalItem, LotteryPanel uiParent) {
//数据初始化
this.packageLocalItem = packageLocalItem;
this.packageTableItem = MainGame.Instance.GetPackageItemById(this.packageLocalItem.id);
this.uiParent = uiParent;

//刷新UI信息
RefreshImage();
}
void RefreshImage() {
Texture2D t = (Texture2D)Resources.Load(this.packageTableItem.imagePath);
Sprite temp = Sprite.Create(t, new Rect(0, 0, t.width, t.height), new Vector2(0, 0));
UIImage.GetComponent<Image>().sprite = temp;
}
public void RefreshStars() {
for (int i = 0; i < UIStars.childCount; i++) {
Transform star = UIStars.GetChild(i);
if (this.packageTableItem.star > i)
star.gameObject.SetActive(true);
else
star.gameObject.SetActive(false);
}
}
}
为了方便拓展的一个排序模式，修改PackagePanel.cs脚本

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public enum PackageMode{
normal,
delete,
sort,
}
public class PackagePanel : BasePanel{
Transform UIMenu;
Transform UIMenuWeapon;
Transform UIMenuFood;
Transform UITabName;
Transform UICloseBtn;
Transform UICenter;
Transform UIScrollView;
Transform UIDetailPanel;
Transform UILeftBtn;
Transform UIRightBtn;
Transform UIDeletePanel;
Transform UIDeleteBackBtn;
Transform UIDeleteInfoText;
Transform UIDeleteConfirmBtn;
Transform UIBottomMenus;
Transform UIDeleteBtn;
Transform UIDetailBtn;
//添加
public GameObject PackageUIItemPrefab;
//添加一列用来容纳所有被选中的物品uid
public List<string> deleteChooseUid;
//添加删除属性
public PackageMode curMode = PackageMode.normal;
public void AddChooseDeleteUid(string uid) {
this.deleteChooseUid ??= new List<string>();
if(!this.deleteChooseUid.Contains(uid))
this.deleteChooseUid.Add(uid);
else
this.deleteChooseUid.Remove(uid);
RefreshDeletePanel();
}
//添加删除选中项
void RefreshDeletePanel(){
RectTransform scrollContent = UIScrollView.GetComponent<ScrollRect>().content;
foreach(Transform cell in scrollContent){
PackageCell packageCell = cell.GetComponent<PackageCell>();
//todo:物品刷新选中状态
//packageCell.RefreshDeleteState();
}
}
//添加表示当前选中的物品时哪一个uid
string _chooseUid;
public string ChooseUid {
get { return _chooseUid; }
set {
_chooseUid = value;
RefreshDetail();
}
}
void RefreshDetail() {
//找到uid对应的动态数据
PackageLocalItem localItem = MainGame.Instance.GetPackageLocalItemByUId(ChooseUid);
//刷新详情界面
UIDetailPanel.GetComponent<PackageDetail>().Refresh(localItem, this);
}
override protected void Awake(){
base.Awake();
InitUI();
}
//添加1
void Start(){
RefreshUI();
}
//添加1
void RefreshUI(){
RefreshScroll();
}
//添加1
void RefreshScroll(){
//清理滚动容器中原本的物品
RectTransform scrollContent = UIScrollView.GetComponent<ScrollRect>().content;
for (int i = 0; i < scrollContent.childCount; i++)
Destroy(scrollContent.GetChild(i).gameObject);
//获取本地数据的方法拿到自己身上背包数据并且根据背包数据初始化滚动容器
foreach (PackageLocalItem localData in MainGame.Instance.GetSortPackageLocalData()){
Transform PackageUIItem = Instantiate(PackageUIItemPrefab.transform, scrollContent) as Transform;

PackageCell packageCell = PackageUIItem.GetComponent<PackageCell>();
//添加2
packageCell.Refresh(localData, this);
}
}
void InitUI(){
InitUIName();
InitClick();
}
void InitUIName(){
UIMenu = transform.Find("TopCenter/Menu");
UIMenuWeapon = transform.Find("TopCenter/Menus/Weapon");
UIMenuFood = transform.Find("TopCenter/Menus/Food");
UITabName = transform.Find("LeftTop/TabName");
UICloseBtn = transform.Find("RightTop/Close");
UICenter = transform.Find("Center");
UIScrollView = transform.Find("Center/Scroll View");
UIDetailPanel = transform.Find("Center/DetailPanel");
UILeftBtn = transform.Find("Left/Button");
UIRightBtn = transform.Find("Right/Button");

UIDeletePanel = transform.Find("Bottom/DeletePanel");
UIDeleteBackBtn = transform.Find("Bottom/DeletePanel/Back");
UIDeleteInfoText = transform.Find("Bottom/DeletePanel/InfoText");
UIDeleteConfirmBtn = transform.Find("Bottom/DeletePanel/ConfirmBtn");
UIBottomMenus = transform.Find("Bottom/BottomMenus");
UIDeleteBtn = transform.Find("Bottom/BottomMenus/DeleteBtn");
UIDetailBtn = transform.Find("Bottom/BottomMenus/DetailBtn");

UIDeletePanel.gameObject.SetActive(false);
UIBottomMenus.gameObject.SetActive(true);
}
void InitClick(){
UIMenuWeapon.GetComponent<Button>().onClick.AddListener(OnClickWeapon);
UIMenuFood.GetComponent<Button>().onClick.AddListener(OnClickFood);
UICloseBtn.GetComponent<Button>().onClick.AddListener(OnClickClose);
UILeftBtn.GetComponent<Button>().onClick.AddListener(OnClickLeft);
UIRightBtn.GetComponent<Button>().onClick.AddListener(OnClickRight);

UIDeleteBackBtn.GetComponent<Button>().onClick.AddListener(OnDeleteBack);
UIDeleteConfirmBtn.GetComponent<Button>().onClick.AddListener(OnDeleteConfirm);
UIDeleteBtn.GetComponent<Button>().onClick.AddListener(OnDelete);
UIDetailBtn.GetComponent<Button>().onClick.AddListener(OnDetail);
}

void OnDetail(){
print(">>>>>>> OnDetail()");
}
//进入删除模式 ; 左下角删除按钮
void OnDelete(){
print(">>>>>>> OnDelete()");
curMode = PackageMode.delete;
UIDeletePanel.gameObject.SetActive(true);
}
//确认删除
void OnDeleteConfirm(){
print(">>>>>>> OnDeleteConfirm()");
if (this.deleteChooseUid == null)
return;
if (this.deleteChooseUid.Count == 0)
return;
MainGame.Instance.DeletePackageItems(this.deleteChooseUid);
//删除完成后刷新整个背包页面
RefreshUI();
}
//退出删除模式
void OnDeleteBack(){
print(">>>>>>> OnDeleteBack()");
curMode = PackageMode.normal;
UIDeletePanel.gameObject.SetActive(false);
//重置选中的删除列表
deleteChooseUid = new List<string>();
//刷新选中状态
RefreshDeletePanel();
}
void OnClickRight(){
print(">>>>>>> OnClickRight()");
}
void OnClickLeft(){
print(">>>>>>> OnClickLeft()");
}
void OnClickWeapon(){
print(">>>>>>> OnClickWeapon()");
}
void OnClickFood(){
print(">>>>>>> OnClickFood()");
}
void OnClickClose(){
ClosePanel();
UIManager.Instance.OpenPanel(UIManager.UIConst.MainPanel);
}
}
这里会出现报红，修改MainGame.cs脚本添加删除方法即可：

using System.Collections.Generic;
using System.Runtime.InteropServices.WindowsRuntime;
using UnityEngine;
using static UIManager;
public class MainGame : MonoBehaviour{

}
else{

}
//刷新星级

}
//刷新星级
public void RefreshStars(){
for (int i = 0; i < UIStars.childCount; i++){
Transform star = UIStars.GetChild(i);
if (this.packageTableItem.star > i)
star.gameObject.SetActive(true);
else
star.gameObject.SetActive(false);
}
}

public void OnPointerClick(PointerEventData eventData){
//if (this.uiParent.ChooseUid == this.packageLocalData.uid)

if (this.uiParent.deleteChooseUid.Contains(this.packageLocalData.uid))
this.UIDeleteSelect.gameObject.SetActive(true);
else
this.UIDeleteSelect.gameObject.SetActive(false);
}
}
最后修改PackagePanel.cs脚本：

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public enum PackageMode{
normal,
delete,
sort,
}
public class PackagePanel : BasePanel{
Transform UIMenu;

Transform UIDeleteConfirmBtn;
Transform UIBottomMenus;
Transform UIDeleteBtn;
Transform UIDetailBtn;
//添加
public GameObject PackageUIItemPrefab;
//添加一列用来容纳所有被选中的物品uid
public List<string> deleteChooseUid;
//添加删除属性
public PackageMode curMode = PackageMode.normal;
public void AddChooseDeleteUid(string uid) {
this.deleteChooseUid ??= new List<string>();
if(!this.deleteChooseUid.Contains(uid))
this.deleteChooseUid.Add(uid);
else
this.deleteChooseUid.Remove(uid);
RefreshDeletePanel();
}
//添加删除选中项
void RefreshDeletePanel(){
RectTransform scrollContent = UIScrollView.GetComponent<ScrollRect>().content;
foreach(Transform cell in scrollContent){

}
}
//添加表示当前选中的物品时哪一个uid

RefreshDetail();
}
}

//找到uid对应的动态数据
PackageLocalItem localItem = MainGame.Instance.GetPackageLocalItemByUId(ChooseUid);
//刷新详情界面
