本文介绍了一个游戏存档系统的实现方式，使用Unity进行开发，并通过XML序列化存储游戏数据。系统包括游戏信息存储类GameData，存档管理类GameDataManager，以及具体的存档数据类如PlayerData等。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

DataBases : 信息基类，存储欲存档的信息。对于各种存档信息可以由此派生。派生类一般不含方法。

DataItems : 信息项基类，操作信息类。为Manager提供所有DataBse。

GameData : 游戏信息，所有需要存档的DataBase都需要存储在改类List中。

GameDataManager : 游戏存档类，提供Save()和Load()接口

实质就是将该类的gamedata对象序列化保存。

XmlSave : Xml序列化类。

PlayerData : 继承DataBase，包含Player需要存档的属性，即坐标，旋转，大小。

PlayerDataItem ：继承DataItem, 主要负责存档时将属性放入PlayerData，读档时利用PlayerData对Player设置属性。

TimeData : 继承DataBase,存储当前消耗时间信息。

TimeDataItem : 继承DataItem,主要负责存档时将属性放入TimeData,读档时利用TimeData对显示时间设置。
