上一个内容:46.x86游戏实战-DXX封包实现进入地图房间
上一个内容实现了进入地图,它call了很多函数
如下图红框圈出来的都是固定的
然后它们的参数每次都要找就很麻烦,如下图,可以在函数头部下断点
然后如下图红框看,这样函数的第一个参数就是esp+4,第二个参数就是esp+4+4以此类推,接下里是采用Windows的异常链的机制来实现断点(详情看:【有道云笔记】VEH Hook异常Hook)使用Windows异常链实现的HOOK 微尘网络 给了封装好的代码(如果不嫌麻烦可以看【有道云笔记】VEH Hook异常Hook看明白之后自己实现一个,其实【有道云笔记】VEH Hook异常Hook里也实现了百分之80或90的功能了,为了不浪费时间跟课程节奏就要采用 微尘网络封装好的代码)
效果图:它就把函数的参数地址打印出来了(EIP寄存器是接下来要运行的代码的地址,也就是当前函数地址)
