【C++】从零开始的CS:GO逆向分析3——写出一个透视
本篇内容包括：
1. 透视实现的方法介绍
2. 通过进程名获取进程id和进程句柄
3. 通过进程id获取进程中的模块信息（模块大小，模块地址，模块句柄）
4. 读取游戏内存（人物ViewMatrix，敌人坐标，敌人生命值，敌人阵营）
5. 三维坐标转二维坐标（游戏内人物坐标转换成屏幕上的坐标）
6. glfw+imgui 在屏幕上的绘制直线
请先依据前两篇，对偏移、基址有基本了解，并且配置好了glfw+imgui的环境，在上篇创建好的工程中创建CPP文件和同名.h文件
实现效果：
透视实现的方法介绍
一般有两种方式，一种是外挂，一种是内挂，外挂是在创建一个透明窗口，在透明窗口上画线，让鼠标事件透过窗口，透明窗口覆盖在游戏窗口上。内挂是通过DLL注入，HOOK游戏中的绘制函数，在游戏绘制人物的时候绘制自己的线。还剩一种比较少用，但也可以实现，找到人物模型ID，在渲染到人物模型的时候关掉渲染缓冲（应该是叫这个？），使人物模型在墙模型前面渲染，导致可以直接看到人物。本篇文章采用的是外挂的形式，根据上篇文章已经可以创建出一个覆盖在屏幕上的透明窗口。
先把需要用到的全局变量声明一下（GetImformation.cpp）
变量名起的挺明白的，就不写注释了
DWORD g_process_id = NULL; HANDLE g_process_handle = NULL; UINT_PTR g_local_player = NULL; UINT_PTR g_player_list_address = NULL; UINT_PTR g_matrix_address = NULL; UINT_PTR g_angle_address = NULL; HWND g_game_hwnd = NULL; module_information engine_module; module_information client_module; module_information server_module; float g_client_width; float g_client_height;
把需要用到的偏移也声明一下
#define dwViewMatrix 0x4DCF254 #define dwLocalPlayer 0xDC14CC #define dwClientState 0x58CFDC #define dwEntityList 0x4DDD93C #define dwClientState_ViewAngles 0x4D90 #define m_vecOrigin 0x138 #define m_bDormant 0xED #define m_lifeState 0x25F #define m_iHealth 0x100 #define m_iTeamNum 0xF4
再把需要使用到的函数先声明和实现（GetImformation.cpp），实现思路写在后面
获取屏幕大小，保存到全局变量
void GetWindowSize() { HDC hdc = GetDC(nullptr); g_client_width = GetDeviceCaps(hdc, DESKTOPHORZRES); g_client_height = GetDeviceCaps(hdc, DESKTOPVERTRES); ReleaseDC(nullptr, hdc); }
先写一个错误获取函数，以方便获取出错的信息
void error(const char*text) { MessageBoxA(nullptr, text, nullptr, MB_OK); exit(-1); } bool is_error() { return GetLastError() != 0; }
通过进程名获取进程id和进程句柄
使用CreateToolhelp32Snapshot函数，创建进程快照，遍历系统快照中的进程名，遍历到process_name,则返回该进程的进程ID
DWORD get_process_id(const char*process_name) { HANDLE snap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0); if (is_error()) error("CreateToolhelp32Snapshot失败"); PROCESSENTRY32 process_info; ZeroMemory(&process_info, sizeof(process_info)); process_info.dwSize = sizeof(process_info); char target[1024]; ZeroMemory(target, 1024); strncpy_s(target, process_name, strlen(process_name)); _strupr(target); bool state = Process32First(snap, &process_info); while (state) { if (strncmp(_strupr(process_info.szExeFile), target, strlen(target)) == 0) { return process_info.th32ProcessID; } state = Process32Next(snap, &process_info); } CloseHandle(snap); return 0; }
通过进程ID获取进程句柄
HANDLE get_process_handle(DWORD process_id) { HANDLE process_handle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, process_id); if (is_error()) error("get_process_handle失败"); return process_handle; }
通过进程id获取进程中的模块信息（模块大小，模块地址，模块句柄）
可以发现偏移都是由 client.dll+xxxxx 此种形式构成，所以需要获取模块的地址
先创建一个模块结构体，需要获取模块的模块大小，模块地址，模块句柄
class module_information { public: HANDLE module_handle; char module_name[1024]; char *module_data; UINT_PTR module_address; int module_size; void alloc(int size) { module_size = size; module_data = (char *)VirtualAlloc(nullptr, size, MEM_COMMIT | MEM_RESERVE, PAGE_EXECUTE_READWRITE); if (is_error())error("申请内存失败"); } void release() { if (module_data)VirtualFree(module_data, 0, MEM_RELEASE); module_data = nullptr; } };
传入进程ID和需要获取的模块名，CreateToolhelp32Snapshot创建模块快照，遍历快照，比对模块名，获取模块信息
void get_moduel_info(DWORD process_id, const char *name, OUT module_information&info) { HANDLE snap = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, process_id); if (is_error())error("创建快照错误"); MODULEENTRY32 module_info; ZeroMemory(&module_info, sizeof(module_info)); module_info.dwSize = sizeof(module_info); char target[1024]; ZeroMemory(target, 1024); strncpy(target, name, strlen(name)); _strupr(target); bool status = Module32First(snap, &module_info); while (status) { if (strncmp(_strupr(module_info.szModule), target, sizeof(target)) == 0) { info.module_address = (UINT_PTR)module_info.modBaseAddr; info.module_handle = module_info.hModule; info.alloc(module_info.modBaseSize); DWORD size = read_memory(g_process_handle, info.module_address, info.module_data, info.module_size);//TODO CloseHandle(snap); return; } status = Module32Next(snap, &module_info); } error("未找到模块"); return; }
读取游戏内存函数
例如之前得到 上下角度 = [[engine.dll+58CFDC]+00004D90] ，则可以
ReadProcessMemory(g_process_handle, (LPVOID)(engine.dll+58CFDC), recv, size, &readsize);
ReadProcessMemory(g_process_handle, (LPVOID)recv, recv, size, &readsize);
函数的使用方法：ReadProcessMemory(句柄,地址,读到哪里,读多少,具体读了多少);
则可以读到上下角度
通过ReadProcessMemory函数读取内存，对这个函数进行打包，方便使用（好吧，我承认这个打包的很烂，几乎没有方便使用）
DWORD read_memory(HANDLE process, DWORD address, void *recv, int size) { DWORD readsize; ReadProcessMemory(process, (LPVOID)address, recv, size, &readsize); return readsize; if (is_error())error("读取内存失败"); }
重写了一个我觉得比较好用的，各位可以酌情对其进行改写
template<class T> T ReadMem(HANDLE ProcessHandle, UINT_PTR Address, int size) { T Reader; ReadProcessMemory(ProcessHandle, (LPVOID)Address, &Reader, size, NULL); return Reader; }
三维坐标转二维坐标
创建两个结构体来储存二维坐标，一个用来储存三维坐标
struct Vec2 {
public: float x, y; }; struct Vec3 { public: float x, y, z; };
传入一个三维坐标和视角矩阵，算出人物在屏幕上的坐标 VecScreen
bool WorldToScreen(const Vec3& VecOrgin, Vec2& VecScreen, float* Matrix) { VecScreen.x = VecOrgin.x *Matrix[0] + VecOrgin.y*Matrix[1] + VecOrgin.z*Matrix[2] + Matrix[3]; VecScreen.y = VecOrgin.x *Matrix[4] + VecOrgin.y*Matrix[5] + VecOrgin.z*Matrix[6] + Matrix[7]; float w = VecOrgin.x*Matrix[12] + VecOrgin.y*Matrix[13] + VecOrgin.z*Matrix[14] + Matrix[15]; if (w < 0.01f) { return false; } Vec2 NDC; NDC.x = VecScreen.x / w; NDC.y = VecScreen.y / w; VecScreen.x = (g_client_width / 2 * NDC.x) + (NDC.x + g_client_width / 2); VecScreen.y = (g_client_height / 2 * NDC.y) + (NDC.y + g_client_height / 2); ConvertToRange(VecScreen); return true; } void ConvertToRange(Vec2 &Point) { Point.x /= g_client_width; Point.x *= 2.0f; Point.x -= 1.0f; Point.y /= g_client_height; Point.y *= 2.0f; Point.y -= 1.0f; }
GLFW画线
使用glVertex2f函数，第一个glVertex2f是开始的位置，第二个glVertex2f是结束的位置
void DrawLine(Vec2& start, Vec2& end) { glLineWidth(1.2); glBegin(GL_LINES); glColor4f(255, 255, 255, 100); glVertex2f(start.x, start.y); glVertex2f(end.x, end.y); glEnd(); }
写一个init函数，实现初始化
void init_address(const char*process_name) { std::cout << "请先启动游戏"<< std::endl; DWORD process_id = get_process_id(process_name); HANDLE process_handle = get_process_handle(process_id); g_process_id = process_id; //将pid保存到全局变量 g_process_handle = process_handle;//将process_handle保存到全局变量 //获取模块信息 get_moduel_info(process_id, "engine.dll", engine_module); get_moduel_info(process_id, "client.dll", client_module); get_moduel_info(process_id, "server.dll", server_module); UINT_PTR temp_address; float Matrix[16]; UINT_PTR matrix_address = client_module.module_address + dwViewMatrix; //获取视角矩阵地址 g_matrix_address = matrix_address; //将视角矩阵地址保存到全局变量 //获取人物视角地址 ReadProcessMemory(g_process_handle, (LPVOID)(engine_module.module_address + 0x58CFDC), &temp_address, 4, NULL);//[engine.dll + 58CFDC]+00004D90 g_angle_address = temp_address + dwClientState_ViewAngles; //获取本地人物地址 [client.dll+0xDC04CC]+100 = 生命值 ReadProcessMemory(g_process_handle, (LPVOID)(client_module.module_address + dwLocalPlayer), &temp_address, 4, NULL); g_local_player = temp_address; //[g_local_player+100] = 生命值 //获得ENtitylist地址 [client.dll+0x4DDC90C + i *0x10]+100 = 敌人生命值 g_player_list_address = client_module.module_address + dwEntityList; }
先说一下整体的思路：
通过进程名（csgo.exe）获取进程ID
↓
通过进程ID获取进程句柄、client.dll模块的信息
↓
通过进程句柄读取人物视角矩阵地址、本地人物对象地址、敌人对象地址 并保存到全局变量（初始化完成）
↓
获得屏幕大小储存在全局变量、创建透明窗口
↓
循环遍历敌人对象，通过地址读取到人物的视角矩阵、敌人的位置
↓
在循环中将敌人的位置结合矩阵，转换成2D坐标
↓
再循环中在透明窗口上把算出来的坐标画出来
再写一段伪代码出来帮助理解，代码贴在后面
int main { 获取视角矩阵地址、获取本地人物地址、获取敌人对象地址 获取屏幕分辨率 根据屏幕分辨率创建窗口 while（1）消息循环 {
清除画的线 获得视角矩阵，因为会变，所以需要不停的获取 for(int i=0;i<64;i++)因为游戏人数最大为64 { 获得自己的阵营 获取当前敌人对象 根据对象获取人物血量、阵营、生存状态、敌人是否有效 如果敌人血量<=0 或者 敌人阵营=自己阵营 或者 无效 或者 敌人对象为空 或者 敌人生存状态
则遍历下一个对象 获得敌人的位置 将敌人的坐标转换为2D坐标 画线 } } }

至此一个简单的透视就写完了，本系列也完结力....
后记：
感觉有些地方逻辑讲的不是很清晰，有问题可以在评论区里提
里面写的偏移全都是写死的，等CSGO一更新就不能用了，解决这个问题的方法，就是写一个特征码查找，但不能保证所有人都是来学思路和方法的，对于直接copy代码的，起码偏移要自己找一下。
方框、自瞄、防闪其实也写了，但感觉不是很适合在这里发，如果后面想发了，再写一个补充篇吧
因为是从一堆功能中抽出一个小透，所以可能报错，少点什么东西，能自己补的自己补一下，不能的评论区说一下，我来补
