注：！！！untiy 打包安卓平台不允许使用Unity自带的json工具Newtonsoft.Json

LitJson不支持float类型的字符。

LitJson支持的格式如下：

public JsonData(bool boolean);  
public JsonData(double number);  
public JsonData(int number);  
public JsonData(long number);
public JsonData(object obj) 
public JsonData(string str); 

需要让LitJson支持Float类型的方式：

    在Awake里面或者在初始化协程里面调用方法即可

/// <summary>
    /// LitJson数据转换，可使用Float
    /// </summary>
    private static void RegisterFloat()
    {
        void Exporter(float obj, JsonWriter writer)
        {
            writer.Write(obj);
        }

        JsonMapper.RegisterExporter((ExporterFunc<float>)Exporter);

        float Importer(double obj)
        {
            return (float)obj;
        }

        JsonMapper.RegisterImporter((ImporterFunc<double, float>)Importer);
    }

安卓端,IOS,PC的JSON转换（通用）

保存JSON脚本展示，放入单例脚本中，方便调用

/// <summary>/// Json保存/// </summary>/// <typeparam name="T">数据类型</typeparam>/// <param name="data">对象</param>public void SaveRoleData<T>(T data,string name){Debug.Log("数据保存");string path = Application.persistentDataPath + "/"+ name;string saveJsonStr = JsonMapper.ToJson(data);   //序列化JSON文件，写入JsonFile.WriteAllText(path, saveJsonStr);}
