Unity 数据存储PlayerPrefs管理类

实现存取实体类对象

存储格式为Json格式

源码如下:

Singleton.cs


//单例模板
public class Singleton<T> where T : new()
{

    private static T _Instance;

    public static T Instance
    {
        get
        {
            if (_Instance == null)
            {
                _Instance = new T();
            }
            return _Instance;
        }
    }

    public Singleton()
    {

    }
}

InventoryEntity.cs

/// <summary>
/// 实体类
/// </summary>
public class InventoryEntity {

    /// <summary>
    /// 金币
    /// </summary>
    public int coins = 0;

    /// <summary>
    /// 钻石
    /// </summary>
    public int gams = 0;

    /// <summary>
    /// 关卡
    /// </summary>
    public int Levels = 1;

    public InventoryEntity()
    {

    }

    public InventoryEntity(int coin, int gam, int level)
    {
        this.coins = coin;
        this.gams = gam;
        this.Levels = level;
    }
}

DataManager.cs

using UnityEngine;

public class DataManager : Singleton<DataManager>
{

    /// <summary>
    /// 保存数据
    /// </summary>
    InventoryEntity m_Inventory;

    /// <summary>

    public void Init()
    {
        m_Inventory = GetObjectData<InventoryEntity>("data");
    }

    #region 人物ID读写

    private string m_playerId = "";

    /// <summary>

}

用法如下

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class DataTest : MonoBehaviour {

	// Use this for initialization
	void Start () {
        DataManager.Instance.Init();
        Debug.LogError("金币"+DataManager.Instance.GetCoins());
        Debug.LogError("宝石"+DataManager.Instance.GetGams());
        Debug.LogError("关卡" + DataManager.Instance.GetLevels());

        DataManager.Instance.SetAward(10,20,3);
	}

}
