逆向分析
I. 分析相机受谁控制
- 由Unity中的一个轨道控制
II. 分析怎么修改Mv出装
- 分析调用流程
- 触发UI事件：UpdateDeckSuit
- 发送网络请求：SaveLiveMvDeckRequest → DotUnder.Rule.Send
- 处理user model更新：UserModelResponse → UpdateUserModel
- 我们hook网络请求发送，判断是不是SaveLiveMvDeckRequest，如果是就直接返回，不发给服务器
- 构造返回值
- 生成Dictionary：通过MiniJSON_Json__Deserialize生成一个System_Collections_Generic_Dictionary_string__object__o
- 生成UserModelResponse：通过DotUnder_Serialization__DeserializeUserModelResponse解析上面的dict
- 设置返回内容：
- 通过DotUnder_Structure_UserModelResponse__set_UserModel设置
- < 3.0.0：服务器始终返回全量UserModel，因此我们直接复制一份原来的UserModel，然后修改其中的一部分内容即可
- > 3.0.0：服务器返回增量UserModel
- 每次的UserModel中必定带有UserStatus，其他信息可选携带
- 返回的Dictionary中每个key代表该key在原来的userModel中发生了变化。如果是value为空，则代表删除
- 我们捕获服务器返回的UserModel数据
