　　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）

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

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]+00004D90g_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
