盘子脸在制作单机游戏的时候,先以为没有好多数据需要保存本地. 就没有使用json等格式自己进行保存. 使用PlayerPrefs类,但是后面字段越来越多的时候.

PlayerPrefs保存就发现要手动写很多代码. 于是是否可以写一个辅助方法自动帮我保存一个对象,取出一个对象呢?

代码如何下:

public static class PlayerPrefsExtend {    public static void Save(string objectName,LocalEntityBase o)     {        Type t = o.GetType();        FieldInfo [] fiedls =  t.GetFields();        for (int i = 0; i < fiedls.Length; i++)        {            string saveName = objectName + "." + o.Identification + "." + fiedls[i].Name;            switch (fiedls[i].FieldType.Name)            {                case "String":                    PlayerPrefs.SetString(saveName, fiedls[i].GetValue(o).ToString());                    break;                case "Int32":                case "Int64":                case "Int":                case "uInt":                    PlayerPrefs.SetInt(saveName, (int)fiedls[i].GetValue(o));                    break;                case "Float":                    PlayerPrefs.SetFloat(saveName, (float)fiedls[i].GetValue(o));                    break;            }        }    }    public static T GetValue
     
      (string objectName) where T : LocalEntityBase, new()    {        T newObj = new T();        Type t = newObj.GetType();        FieldInfo[] fiedls = t.GetFields();        for (int i = 0; i < fiedls.Length; i++)        {            string saveName = objectName + "." + newObj.Identification + "." + fiedls[i].Name;            switch (fiedls[i].FieldType.Name)            {                case "String":                    fiedls[i].SetValue(newObj,PlayerPrefs.GetString(saveName));                    break;                case "Int32":                case "Int64":                case "Int":                case "uInt":                    fiedls[i].SetValue(newObj, PlayerPrefs.GetInt(saveName));                    break;                case "Float":                    fiedls[i].SetValue(newObj,PlayerPrefs.GetFloat(saveName));                    break;            }        }        return newObj;    }}
     

操作代码 ：

PlayerPrefs.DeleteAll();User user = new User();user.Name = "盘子脸";user.Age = 10;user.Describe = "码农=。= ";PlayerPrefsExtend.Save("ID1", user);user = null;user = PlayerPrefsExtend.GetValue
     
      ("ID1");Debug.Log("user name: " + user.Name);Debug.Log("user Age: " + user.Age);Debug.Log("user Describe: " + user.Describe);//以前的写法,就要手动写很多key.//PlayerPrefs.SetString("Name", user.Name);//PlayerPrefs.SetInt("Age", user.Age);//PlayerPrefs.GetString("Describe", user.Describe);
     

效果图:
