WirteAddressOffset : 寫入基址,偏移
void WriteAddressOffset(DWORD baseAddress, std::vector<DWORD> offsets, int value)
{
      HANDLE hProcess = GetPvZProcessHandle();//這邊只是我讀取我遊戲的進程
      if (hProcess == NULL) return;
      DWORD currentAddress;
      SIZE_T bytesRead;
      if (!ReadProcessMemory(hProcess, (LPCVOID)baseAddress, ¤tAddress, sizeof(currentAddress), &bytesRead)) {
            CloseHandle(hProcess);
            return;
      }
      for (size_t i = 0; i < offsets.size(); i++) {
            currentAddress += offsets;
            if (i != offsets.size() - 1) {
                     if (!ReadProcessMemory(hProcess, (LPCVOID)currentAddress, ¤tAddress, sizeof(currentAddress), &bytesRead)) {
                              CloseHandle(hProcess);
                              return;
                     }
            }
      }
      if (!WriteProcessMemory(hProcess, (LPVOID)currentAddress, &value, sizeof(value), NULL)) {
            CloseHandle(hProcess);
            return;
      }
      CloseHandle(hProcess);//關閉進程
}

例句: WriteAddressOffset(0x006A9EC0, {0x768, 0x5560}, 9990); //基址, 一級偏移 , 二級偏移, 數值 (在裡面處理多個偏移也都是沒有問題
---------------------------------------------------------------------------------------------------------------------------------------------------------------
WriteBytes : 寫入4自節
static bool WriteBytes(DWORD dwAddr, const std::initializer_list<unsigned char>& bytes) //用來寫入數據
{
      DWORD dwOld;
      size_t len = bytes.size();
      if (!VirtualProtect((LPVOID)dwAddr, len, PAGE_EXECUTE_READWRITE, &dwOld)) {
            return false;
      }
      memcpy_s((void*)dwAddr, len, bytes.begin(), len);
      DWORD dwNew;
      return VirtualProtect((LPVOID)dwAddr, len, dwOld, &dwNew);
}

例: WriteBytes(0x0054EBA8, { 0xEB, 0x00, 0x80 });
---------------------------------------------------------------------------------------------------------------------------------------------------------------
Write2Byte : 專門用來寫入2個字節的數據
static bool Write2Byte(DWORD dwAddr, WORD value) //WORD是2字節(16位)
{
      DWORD dwOld;
      if (!VirtualProtect((LPVOID)dwAddr, sizeof(WORD), PAGE_EXECUTE_READWRITE, &dwOld)) {
            return false;
      }
      *(WORD*)dwAddr = value;
      DWORD dwNew;
      return VirtualProtect((LPVOID)dwAddr, sizeof(WORD), dwOld, &dwNew);
}
例:Write2Byte(0x0040E477,0xEB46);
---------------------------------------------------------------------------------------------------------------------------------------------------------------
Write8Byte:  專門用來寫入8個字節的數據
static bool Write8Byte(DWORD dwAddr, uint64_t value) //8字節(64位)
{
      DWORD dwOld;
      if (!VirtualProtect((LPVOID)dwAddr, sizeof(uint64_t), PAGE_EXECUTE_READWRITE, &dwOld)) {
            return false;
      }
      *(uint64_t*)dwAddr = value;
      DWORD dwNew;
      return VirtualProtect((LPVOID)dwAddr, sizeof(uint64_t), dwOld, &dwNew);
}
例:Write8Byte(0x0040D7D0,0xB001C3285357);
---------------------------------------------------------------------------------------------------------------------------------------------------------------
WriteFloat : 專門用來寫入 4 字節的浮點數
static bool WriteFloat(DWORD dwAddr, float value) //4字節的浮點數
{
      DWORD dwOld;
      if (!VirtualProtect((LPVOID)dwAddr, sizeof(float), PAGE_EXECUTE_READWRITE, &dwOld)) {
            return false;
      }
      *(float*)dwAddr = value;
      DWORD dwNew;
      return VirtualProtect((LPVOID)dwAddr, sizeof(float), dwOld, &dwNew);
}
例: WriteFloat(0x0040F000, 1.23f);
