本文主要是介绍71.网络游戏逆向分析与漏洞攻防-角色与怪物信息的更新-分析并利用角色与怪物创建的数据包，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

如果看不懂、不知道现在做的什么，那就跟着做完看效果
现在的代码都是依据数据包来写的，如果看不懂代码，就说明没看懂数据包

以 69.利用封包更新角色数据到结构体 它的代码为基础进行修改
上一个内容里，分析出了更新角色的数据包 和 附近角色附近怪物初始化的数据包，本次先把附近角色、附近怪物初始化的数据包定义好
下图是角色刚登录进游戏，然后可以看到地图里有7个怪物
经过上个内容知道30数据包是附近角色或怪物（NPC）的初始化信息，下图30后面跟着一个7，这说明30数据包里面存在多个角色或NPC的初始化信息
数据拆分，除了30后面的个数其余与28数据包一样，由于数据包很长一屏只能显示一个多点，其实它是有7个的，完整的数据包提交到码云了，名字为 30数据包.txt
GameOBJECT.h和GameOBJECT.cpp文件有修改，需要重新生成一次，修改的什么详情看GameAnly.cpp文件里的CreateObjectfiles函数
GameAnly.cpp文件的修改：修改了 CreateObjectfiles函数
