：模拟 按Button增加经验，经验改变后，玩家达到当前等级*100经验后升级，升级后给玩家增加当前等级*10的金币，每3级增加钻石10；
1、创建一个头像面板模拟MVC模式
2、创建一个SQL数据库保存玩家数据
2、给Head添加4个脚本:
Model（模型） ： PlayerModel脚本代码：
using System.Collections; using System.Collections.Generic; using UnityEngine; /// <summary> /// 值改变的委托 /// </summary> /// <param name="value"></param> public delegate void OnValueChangeEventHandle(float value); public class PlayerModel : MonoBehaviour { private float playerExperience; private int playerLevel; private int playerCoin; private int playerDiamond; /// <summary> /// 经验改变事件（猫进来了=经验改变了）, /// 观察这只猫的动物身上的逃跑方法触发（注册了经验改变这个事件的对象身上的方法触发）） /// UI更新显示的方法触发，数据库更新的方法触发 /// </summary> public event OnValueChangeEventHandle OnExperienceChange; /// <summary> /// 玩家经验 /// </summary> public float PlayerExperience { set { playerExperience = value; //经验被更新后(经验被改变),触发事件，调用所有绑定了该事件的方法 OnExperienceChange(PlayerExperience); } get { return playerExperience; } } /// <summary> /// 玩家等级 /// </summary> public int PlayerLevel { set { playerLevel = value; //经验更新后触发经验改变事件 OnExperienceChange(PlayerExperience); } get { return playerLevel; } } /// <summary> /// 玩家金币 /// </summary> public int PlayerCoin { set { playerCoin = value; //经验更新后触发事件 OnExperienceChange(PlayerExperience); } get { return playerCoin; } } /// <summary> /// 玩家钻石 /// </summary> public int PlayerDiamond { set { playerDiamond = value; //触发事件 OnExperienceChange(PlayerExperience); } get { return playerDiamond; } } }
View（视图）：PlayerView
using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; public class PlayerView : MonoBehaviour { public Text levelText; public Text experienceText; public Slider experienceSlider; public Text coinText; public Text diamondText; private PlayerModel model; public Button addExpBut; private void Awake() { model = GetComponent<PlayerModel>(); } /// <summary> /// 显示数据(注册到事件里，当事件被触发，方法被调用) /// </summary> /// <param name="ex"></param> public void ShowData(float ex) { levelText.text = model.PlayerLevel.ToString(); experienceText.text = model.PlayerExperience.ToString() + "/"+(model.PlayerLevel*100).ToString(); coinText.text = model.PlayerCoin.ToString(); diamondText.text = model.PlayerDiamond.ToString(); experienceSlider.value = model.PlayerExperience / (model.PlayerLevel * 100); } }
Controller（控制器）：PlayerController代码：
using System.Collections; using System.Collections.Generic; using UnityEngine; public class PlayerController : MonoBehaviour { private PlayerModel model; private PlayerDB db; private PlayerView view; private void Awake() { model = GetComponent<PlayerModel>(); db = GetComponent<PlayerDB>(); view = GetComponent<PlayerView>(); } void Start() { //打开数据库 db.OpenDB("MVC"); //UI里显示数据的方法，绑定到经验改变事件 model.OnExperienceChange += view.ShowData; //数据库的数据同步到模型 db.Synchronization(); //数据库操作的方法，绑定到经验改变事件 model.OnExperienceChange += db.UpdatePlayerData; //增加经验的方法，绑定到鼠标点击事件 view.addExpBut.onClick.AddListener(OnBtnClick); } private void OnDestroy() { db.CloseDB(); //关闭数据库 } void OnBtnClick() { AddExperience(50); //增加经验 } /// <summary> /// 增加经验 /// </summary> /// <param name="exp"></param> public void AddExperience(float exp) { //当前的经验 = 已有经验 + 增加的经验 float currentExp = model.PlayerExperience + exp; while (currentExp>model.PlayerLevel*100) { //获取剩余经验 currentExp -= model.PlayerLevel * 100; //升级 model.PlayerLevel++; //金币增加 model.PlayerCoin += model.PlayerLevel * 10; //每升3级钻石增加10 if (model.PlayerLevel%3==0) { model.PlayerDiamond += 10; } } //剩余经验赋值到模型 model.PlayerExperience = currentExp; } }
数据库操作：PlayerDB代码：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Mono.Data.Sqlite;
public class PlayerDB : MonoBehaviour
{
private string dataPath;
private SqliteCommand command;
private SqliteConnection con;
private SqliteDataReader reader;
private PlayerModel playerModel;
private void Awake()
{
playerModel = GetComponent<PlayerModel>();
}
/// <summary>
/// 打开数据库
/// </summary>
/// <param name="DBName"></param>
public void OpenDB(string DBName)
{
//拼凑路径
dataPath = "Data Source==" + Application.streamingAssetsPath +
"/" + DBName + ".sqlite";
con = new SqliteConnection(dataPath);
command = con.CreateCommand();
con.Open();
}
/// <summary>
/// 关闭数据库
/// </summary>
public void CloseDB()
{
reader.Close();
reader = null;
con.Clone();
}
/// <summary>
/// 更新玩家数据库(已经注册到经验改变事件里，当经验发生改变时，会调用这个方法)
/// </summary>
/// <param name="ex"></param>
public void UpdatePlayerData(float ex)
{
string query = "Update PlayerData Set playerLevlel=‘" +
playerModel.PlayerLevel + "‘,playerExperience=‘" +
playerModel.PlayerExperience + "‘,playerCoin=‘" +
playerModel.PlayerCoin + "‘,playerDiamond=‘" + playerModel.PlayerDiamond + "‘";
command.CommandText = query;
command.ExecuteNonQuery();
}
/// <summary>
/// 将数据库数据同步到模型
/// </summary>
public void Synchronization()
{
string query = "Select * From PlayerData";
command.CommandText = query;
reader = command.ExecuteReader();
reader.Read();
//同步到模型
playerModel.PlayerLevel = int.Parse(reader.GetValue(0).ToString());
playerModel.PlayerCoin = System.Convert.ToInt32(reader.GetValue(2).ToString());
playerModel.PlayerDiamond = int.Parse(reader.GetValue(3).ToString());
playerModel.PlayerExperience = float.Parse(reader.GetValue(1).ToString());
reader.Close();
}
}
