上一个内容91.加载游戏语言文件到内存
码云版本号aafa72010a0c9ffb42274c1c2ff3a61e627eb49f
代码下载地址在 titan 目录下文件名为titan-利用哈希表实现快速读取文本内容.zip 链接https://pan.baidu.com/s/1W-JpUcGOWbSJmMdmtMzYZg 提取码q9n5 --来自百度网盘超级会员V4的分享 HOOK引擎文件名为黑兔sdk升级版.zip 链接https://pan.baidu.com/s/1IB-Zs6hi3yU8LC2f-8hIEw 提取码78h8 --来自百度网盘超级会员V4的分享 以 91.加载游戏语言文件到内存 它的代码为基础进行修改
现在已经把游戏里的语言文件写到了本次磁盘里并且把这个文件加载到了我们程序的内存中
找有冲突的中文 下图红框里是 textDatas 变量的地址也就是从磁盘文件中加载的语言包的地址 然后打开x96dbg然后附加到游戏 鼠标单击下图红框位置也就是x96dbg的内存窗口位置 然后ctrlg然后输入textDatas 变量的地址 如下图在7CCFF27C位置鼠标右击选择在内存窗口中转到知道DWORD 然后就来到了语言包的内存区域现在还没有赋值所以全是0 然后回到游戏点击确定如下图红框 点击完确定就会有值了 这个原因是弹框的代码是在解析语言包之前 然后第一个不是-1它就是存在哈希冲突 然后找它的链表上图是链表第一个数据通过下图得出的589A8740是链表的第二个数据现在要找链表的最后一个数据找最后一个数据的愿意是为了测试我们通过磁盘文件加载的语言包是否可以用然后DAC*30这个30是十六进制的30的十进制是48这个48是 TextTable 结构的大小 TextTable 结构的大小也就是下图红框位置 然后鼠标单击x96dbg的内存窗口然后按ctrlg然后输入地址然后点确定转到 然后发现它还不是-1所以它不是最后一个数据 继续找 看到它还不是-1 继续 然后就找到-1了 它的中文是水系咏唱法术 0x58D6F9D0位置字符串的效果图 然后发现个事情0x7CCFF27C这个位置的值是0x5897B020但是x96dbg跳过去之后不是了如下图是刚开始的地方x96dbg给我们跳到了0x5897B050位置了但是找哈希冲突的值也还是上方那样的找发图都截完了才发现x96dbg给跳错了 TextManger.cpp文件的修改修改了 LoadTextData函数、ReadTextById函数
