商城系统练习
一、商城界面搭建ShopPanel
1.创建Title_Txt——>商城
2.(1).创建Image，命名为ScrollRect,添加ScrollRect组件
设置Rect Transform
设置ScrollRect组件
(2).创建SkinName_txt——>皮肤名字
(3).创建SkinPrice_txt——>皮肤价格，在其下创建Text——>￥
(4).创建Image，命名为content，设置其RectTransform（可以拖动的范围）
（5).创建Image，命名为skinPrefabs,设置其RectTransform
（6).在其下创建Image，Width=220，Height=220；
（7).将skinPrefabs拖成预制体
3.创建Btn_Buy按钮，购买按钮
4.创建Btn_Select按钮，选择按钮
5.创建Money_txt——>金币数：创建子物体text——>钱数
6.创建退出界面按钮
7.创建Tips_txt——>金币不足！
8.创建Btn_Reset按钮——>游戏重置
二、添加功能
1.创建GameData脚本
[System.Serializable]
public class GameData
{
private bool isFirstGame;//是否是第一次游戏
private int[] bestScoreArr;//最好成绩（前三）
private int selectSkin;//当前选择皮肤
private bool[] skinUnlocked;//没有解锁的皮肤
private int diamondCount;//金币总数
//Set为保存数据调用
public void SetIsFirstGame(bool isFirstGame)
{
this.isFirstGame = isFirstGame;
}
public void SetBestScoreArr(int[] bestScoreArr)
{
this.bestScoreArr = bestScoreArr;
}
public void SetSelectSkin(int selectSkin)
{
this.selectSkin = selectSkin;
}
public void SetSkinUnlocked(bool[] skinUnlocked)
{
this.skinUnlocked = skinUnlocked;
}
public void SetDiamondCount(int diamondCount)
{
this.diamondCount = diamondCount;
}
//Get为加载数据调用
public bool GetIsFirstGame()
{
return isFirstGame;
}
public int[] GetBestScoreArr()
{
return bestScoreArr;
}
public int GetSelectSkin()
{
return selectSkin;
}
public bool[] GetSkinUnlocked()
{
return skinUnlocked;
}
public int GetDiamondCount()
{
return diamondCount;
}
}
2.创建GameController脚本，挂在一个空物体上
using UnityEngine;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;
public class GameController : MonoBehaviour
{
public static GameController insance;
private bool isFirstGame;//是否是第一次游戏
private int[] bestScoreArr;//最好成绩（前三）
private int selectSkin;//当前选择皮肤
public bool[] skinUnlocked;//没有解锁的皮肤
private int diamondCount;//金币总数
private GameData data;
private StoreContainer storecontainer;
public void Awake()
{
insance = this;
InitGameData();
}
// 初始化游戏数据
private void InitGameData()
{
LoadData();//加载游戏数据
if (data != null)
{
isFirstGame = data.GetIsFirstGame();
}
else//是第一次游戏
{
isFirstGame = true;//第一次游戏设为true
}
//如果第一次开始游戏
if (isFirstGame)
{
isFirstGame = false;
bestScoreArr = new int[3];//前三名最好成绩
selectSkin = 0;//当前选择的第一个皮肤
skinUnlocked = new bool[StoreContainer.Instance.skinSprite.Count];
skinUnlocked[0] = true;//默认第一个皮肤解锁
diamondCount = 80;//金币数默认10个
data = new GameData();
SaveData();//保存数据
}
else//如果不是第一次从本地内存中加载数据
{
bestScoreArr = data.GetBestScoreArr();
selectSkin = data.GetSelectSkin();
skinUnlocked = data.GetSkinUnlocked();
diamondCount = data.GetDiamondCount();
}
}
//保存游戏数据
public void SaveData()
{
try//可能出现异常的代码
{
BinaryFormatter bf = new BinaryFormatter();
//使用using后不用关闭文件流
using (FileStream fileStream = File.Create(Application.persistentDataPath+ "/GameData.data"))
{
data.SetBestScoreArr(bestScoreArr);
data.SetDiamondCount(diamondCount);
data.SetIsFirstGame(isFirstGame);
data.SetSelectSkin(selectSkin);
data.SetSkinUnlocked(skinUnlocked);
bf.Serialize(fileStream, data);
}
}//出现异常后执行的代码
catch (System.Exception e)
{
Debug.Log(e.Message);
}
}
//加载游戏数据
public void LoadData()
{
try
{
BinaryFormatter bf = new BinaryFormatter();
using (FileStream fileStream = File.Open(Application.persistentDataPath + "/GameData.data", FileMode.Open))
{
data = (GameData)bf.Deserialize(fileStream);
}
}
catch (System.Exception e)
{
Debug.Log(e.Message);
}
}
// 重置数据
public void ResetData()
{
isFirstGame = false;
bestScoreArr = new int[3];
selectSkin = 0;
skinUnlocked = new bool[StoreContainer.Instance.skinSprite.Count];
skinUnlocked[0] = true;
diamondCount = 80;
SaveData();
}
//获取当前皮肤是否解锁
public bool GetSkinUnlocked(int index)
{
return skinUnlocked[index];
}
// 设置当前皮肤解锁
public void SetSkinUnloacked(int index)
{
skinUnlocked[index] = true;
SaveData();
}
//总金币数量
public int AllCoinNumber()
{
return diamondCount;
}
//更新总金币数量
public void UpdataCoinNumber(int value)
{
diamondCount += value;
SaveData();
}
//设置当前选择的皮肤下标
public void SetSelectedSkin(int index)
{
selectSkin = index;
SaveData();
}
// 获得当前选择的皮肤
public int GetCurrentSelectedSkin()
{
return selectSkin;
}
}
3.创建StoreContainer脚本，挂在一个空物体上
public class StoreContainer : SingletonDontDestroy
{
[Header("皮肤名字")]
[SerializeField] public string[] skinName;
[Header("皮肤价格")]
[SerializeField] public string[] skinPrice;
[Header("皮肤贴图")]
[SerializeField] public List
}
4.创建ShopSystem脚本，挂在ShopPanel上
using UnityEngine;
using DG.Tweening;
using UnityEngine.UI;
public class ShopSystem : MonoBehaviour
{
public Transform content;
public GameObject skingirlPrefabs;
public Text txt_skinName;//皮肤名字
public Text txt_skinPrice;//皮肤价格显示
public Text txt_AllMoneyNumber;//金币总总数
public Text txt_Tip;//金币不够文字提示
public Text moneyText;//皮肤价格符号显示
public Button btn_Buy;//购买按钮
public Button btn_Select;//选择按钮
public int SkinCount;//皮肤个数
public Image player;//玩家
public int currentSelectIndex;//当前选择索引
void Start()
{
Init();
}
void Update()
{
currentSelectIndex = (int)Mathf.Round(content.transform.localPosition.x/-320);
//Debug.Log("当前索引" + currentSelectIndex);
if (Input.GetMouseButtonUp(0))
{
content.transform.DOLocalMoveX(currentSelectIndex * -320, 0.2f);//根据当前索引每次向左滑动160
}
//没解锁
if (GameController.insance.GetSkinUnlocked(currentSelectIndex) == false)
{
txt_skinPrice.text = StoreContainer.Instance.skinPrice[currentSelectIndex] .ToString();
content.GetChild(currentSelectIndex).GetChild(0).GetComponent<Image>().color = Color.gray;
moneyText.gameObject.SetActive(true);
}
else
{
txt_skinPrice.text = "已拥有";
moneyText.gameObject.SetActive(false);
content.GetChild(currentSelectIndex).GetChild(0).GetComponent<Image>().color = Color.white;
}
SetItemSize(currentSelectIndex);
RefreshUI(currentSelectIndex);
}
//初始化
public void Init()
{
content.GetComponent<RectTransform>().sizeDelta = new Vector2((SkinCount +5)* 320, 400.0f);//可滑动内容坐标
for(int i=0;i< SkinCount; i++)
{
GameObject girlobj=Instantiate(skingirlPrefabs, content);
//获取不同皮肤精灵图片
girlobj.transform.Find("Image").GetComponent<Image>().sprite = StoreContainer.Instance.skinSprite[i];
//设置皮肤对象生成的位置
girlobj.transform.localPosition = new Vector3((i + 2) * 320 + 160,0,0);
//没解锁皮肤
if (GameController.insance.GetSkinUnlocked(i) == false)
{
girlobj.transform.Find("Image").GetComponent<Image>().color = Color.gray;//显示灰色
}
else
{
girlobj.transform.Find("Image").GetComponent<Image>().color = Color.white;
}
}
//打开界面直接定位到选中的皮肤位置
content.transform.localPosition = new Vector3(GameController.insance.GetCurrentSelectedSkin()*-320,0);
}
//设置皮肤图片尺寸
private void SetItemSize(int selectIndex)
{
//循环拖拽子物体数量
for (int i = 0; i < content.childCount; i++)
{
//当前选择对象
if (selectIndex == i)
{
//选中皮肤图片的尺寸
content.GetChild(i).GetChild(0).GetComponent<RectTransform>().sizeDelta = new Vector2(320, 320);
txt_skinName.text =StoreContainer.Instance.skinName[i].ToString();
}
//没选中对象
else
{
content.GetChild(i).GetChild(0).GetComponent<RectTransform>().sizeDelta = new Vector2(220, 220);
}
}
}
//更新UI
private void RefreshUI(int selectindex)
{
txt_AllMoneyNumber.text = GameController.insance.AllCoinNumber().ToString();
if (GameController.insance.GetSkinUnlocked(selectindex) == false)
{
btn_Buy.gameObject.SetActive(true);
btn_Select.gameObject.SetActive(false);
}
else
{
btn_Select.gameObject.SetActive(true);
btn_Buy.gameObject.SetActive(false);
}
}
//购买按钮
public void BuyOnClick()
{
int price = int.Parse(txt_skinPrice.text);//获取皮肤价格
if (price > GameController.insance.AllCoinNumber())
{
txt_Tip.gameObject.SetActive(true);
return;
}
GameController.insance.UpdataCoinNumber(-price);
GameController.insance.SetSkinUnloacked(currentSelectIndex);
content.GetChild(currentSelectIndex).GetChild(0).GetComponent<Image>().color = Color.white;
}
//选择按钮
public void SelectOnClick()
{
GameController.insance.SetSelectedSkin(currentSelectIndex);
player.sprite = StoreContainer.Instance.skinSprite[currentSelectIndex];
}
}
三、创建MainPanel
1.创建Image，命名为Player——>从商城选择完皮肤，玩家更换皮肤
2.创建Btn_Back按钮——>返回商城界面
3.创建PlayerController脚本
using UnityEngine;
using UnityEngine.UI;
public class PlayerController : MonoBehaviour
{
public Image player;
void Start()
{
ChangeSprite(GameController.insance.GetCurrentSelectedSkin());
}
//更换皮肤
public void ChangeSprite(int selectindex)
{
player.sprite = StoreContainer.Instance.skinSprite[selectindex];
}
}
四、效果展示
