【C++】植物大战僵尸杂交版自动存档——防闪退存档消失

植物大战僵尸杂交版现已更新到v2.0.88，闪退问题还是偶有发生，参考网上现有的方案，简单实现了一个。

原理就是监控存档目录的文件变化，一旦有新的存档，则将其备份。如发生闪退，则还原备份即可。

原目录：C:/ProgramData/PopCap Games/PlantsVsZombies/pvzHE/yourdata

备份目录：C:/ProgramData/PopCap Games/PlantsVsZombies/pvzHE/yourdata_Backup

源代码

#include <windows.h>
#include <iostream>
#include <filesystem>
#include <string>
#include <vector>namespace fs = std::filesystem;void copy_directory(const fs::path &source, const fs::path &destination)
{try{if (!fs::exists(destination)){fs::create_directories(destination);}for (const auto &entry : fs::recursive_directory_iterator(source)){const auto &path = entry.path();auto relativePathStr = path.lexically_relative(source).string();fs::copy(path, destination / relativePathStr, fs::copy_options::overwrite_existing);}}catch (const std::exception &e){std::cerr << "Error: " << e.what() << std::endl;}
}void monitor_directory(const std::wstring &path, const std::wstring &backup_path)
{HANDLE hDir = CreateFileW(path.c_str(),FILE_LIST_DIRECTORY,FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE,NULL,OPEN_EXISTING,FILE_FLAG_BACKUP_SEMANTICS,NULL);if (hDir == INVALID_HANDLE_VALUE){std::cerr << "CreateFile failed with " << GetLastError() << std::endl;return;}char buffer[1024];DWORD bytesReturned;FILE_NOTIFY_INFORMATION *pNotify;std::vector<char> filenameBuffer(MAX_PATH);while (true){if (ReadDirectoryChangesW(hDir,buffer,sizeof(buffer),FALSE,FILE_NOTIFY_CHANGE_FILE_NAME,&bytesReturned,NULL,NULL)){pNotify = (FILE_NOTIFY_INFORMATION *)buffer;do{std::wstring filename(pNotify->FileName, pNotify->FileNameLength / sizeof(WCHAR));if (pNotify->Action == FILE_ACTION_ADDED){std::wcout << L"New file created: " << filename << std::endl;copy_directory(path, backup_path);}pNotify = (FILE_NOTIFY_INFORMATION *)((char *)pNotify + pNotify->NextEntryOffset);} while (pNotify->NextEntryOffset != 0);}else{std::cerr << "ReadDirectoryChangesW failed with " << GetLastError() << std::endl;break;}}CloseHandle(hDir);
}int main()
{std::wstring directory_to_monitor = L"C:/ProgramData/PopCap Games/PlantsVsZombies/pvzHE/yourdata";std::wstring backup_directory = L"C:/ProgramData/PopCap Games/PlantsVsZombies/pvzHE/yourdata_Backup";std::cout << "开始运行" << std::endl;monitor_directory(directory_to_monitor, backup_directory);return EXIT_SUCCESS;
}

注意

需要使用MSVC(VS 2022)以GBK编码保存代码 编译，如需用MinGW编译，则要手动修改部分代码。
