读档功能模块
|
||
|
||
主要功能：
|
||
- load_game: 从JSON文件加载游戏完整状态
|
||
- check_save_compatibility: 检查存档版本兼容性（当前未实现严格检查）
|
||
|
||
加载流程（两阶段）：
|
||
1. 第一阶段：加载所有Avatar对象（relations留空）
|
||
- 通过AvatarLoadMixin.from_save_dict反序列化
|
||
- 配表对象（Technique, Item等）通过id从全局字典获取
|
||
2. 第二阶段：重建Avatar之间的relations网络
|
||
- 必须在所有Avatar加载完成后才能建立引用关系
|
||
|
||
错误容错：
|
||
- 缺失的配表对象引用会被跳过（如删除的Item）
|
||
- 无法重建的动作会被置为None
|
||
- 不存在的Avatar引用会被忽略
|
||
|
||
注意事项：
|
||
- 读档后会重置前端UI状态（头像图像、插值等）
|
||
- 事件历史完整恢复（受限于保存时的数量）
|
||
- 地图从头重建（因为地图是固定的），但会恢复宗门总部位置
