序列化存档之备忘脚本

序列化存档涉及的参数比较多，猛地一下始终是记不住。花时间把比较完整的代码记下来，并做好注释，这样就比较方便以后的使用。

    public class SaveDataClass{
        public string ID;//关卡号
        public string name;//关卡名称
        public string  maxScore{ get; set;}//每关的最高分
        public string starLev{ get; set;}//有星级就是通关，没有就是未通关
    }
    public List<SaveDataClass> dataList=new List<SaveDataClass>();

    void Awake() {
        DontDestroyOnLoad (this.gameObject);

        if (File.Exists (data)) {//再次玩时读取存档
            Read ();
        } else {
            ReadXML ();//读取XML关卡数据
        }
    }

    void ReadXML(){
        dataList.Clear();
        TextAsset t = (TextAsset)Resources.Load("SaveData");//XML文件，里面放置所有关卡的数据
        StringReader sr=new StringReader(t.text);

            dataList.Add(d);
        }
        Save();
    }

    void Read(){

    }

    //退出游戏或通关时调用
    public void Save(){

        BinaryFormatter bf = new BinaryFormatter();
        bf.Serialize(fs,dataList);
