基于QT的游戏修改器

本项目是一个可以修改部分游戏的部分数据的。例如：修改自己做的贪吃蛇的得分。

1.h代码

#pragma once#include <QtWidgets/QMainWindow>
#include "ui_QtModifer.h"
#include<Windows.h>
#include<TlHelp32.h>
#include<QDebug>
#include <QMessageBox>
#include<QHeaderView>const DWORD KONEK = 1024;
const DWORD KPAGE = 4 * KONEK;
const DWORD KONEG = KONEK * KONEK * KONEK;class QtModifer : public QMainWindow
{Q_OBJECTpublic:QtModifer(QWidget *parent = Q_NULLPTR);int row = 0;
private:Ui::QtModiferClass ui;/*int row=0;*/HANDLE hProcess;DWORD dwAddrList[4 * KONEK];DWORD dwAddrCount;DWORD dwTargetList[KONEK];DWORD dwTargetCounter;void refreshshow();void openBtnClicked();void searchBtnClicked();void researchBtnCliked();void modifyBtnClicked();/*void ShowAddrList(DWORD *pDwAddrList, DWORD dwAddrCount);*/void FirstRound(HANDLE hProcess, DWORD dwValue, DWORD *pAddrList, DWORD *pAddrListCounter, const DWORD addrListMax);BOOL CompareOnePage(HANDLE hProcess, DWORD dwBaseAddr, DWORD dwValue, DWORD *pAddrList, DWORD *pAddrListCounter, const DWORD addrListMax);void SecondRound(HANDLE hProcess, DWORD dwValue, DWORD *pAddrList, DWORD dwAddrListCounter, DWORD *pTargetList, DWORD *pTargetCounter);
};

2.刷新按钮实现功能（显示所有的进程）

void QtModifer::refreshshow()
{PROCESSENTRY32 pc;pc.dwSize = sizeof(pc);HANDLE hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);BOOL bMore = Process32First(hProcessSnap, &pc);int i = 0;while (bMore){ui.tableWidget->setRowCount(i + 1);//设置行数ui.tableWidget->setItem(i, 0, new QTableWidgetItem(QString::number(pc.th32ProcessID, 10)));//从DWORD转为QStringui.tableWidget->setItem(i, 1, new QTableWidgetItem(QString::fromWCharArray(pc.szExeFile)));//从WCHAR转为QStringbMore = Process32Next(hProcessSnap, &pc);i++;}CloseHandle(hProcessSnap);
}

3.打开选择的进程功能

void QtModifer::openBtnClicked()
{DWORD dwId = 0;/*DWORD dwSearchValue = 0;DWORD dwAddrList[4 * KONEK] = { 0 };DWORD dwAddrCount = 0;BOOL bRet = FALSE;*//*printf("please input process id which you want to edit:");while (!scanf_s("%u", &dwId)){rewind(stdin);printf("please input again:");}*///printf("\nprocess id = %u\n", dwId);QList<QTableWidgetItem *> items = ui.tableWidget->selectedItems();QTableWidgetItem *itemId = items.at(0);QString procId = itemId->text();dwId = procId.toInt();QTableWidgetItem *itemName= items.at(1);QString procName = itemName->text();ui.lineEdit->setText(procName);hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwId);if (NULL == hProcess){QString info;info = QString("Open process %1 failed").arg(procName);QMessageBox::information(NULL, "提示", info, QMessageBox::Yes);}else{QString info;info = QString("Open process %1 successful").arg(procName);QMessageBox::information(NULL, "提示", info, QMessageBox::Yes);}
}

4.对比功能

BOOL QtModifer::CompareOnePage(HANDLE hProcess, DWORD dwBaseAddr, DWORD dwValue, DWORD * pAddrList, DWORD * pAddrListCounter, const DWORD addrListMax)
{BYTE byPage[KPAGE] = { 0 };//读一页数据到该数组if (!ReadProcessMemory(hProcess, (LPCVOID)dwBaseAddr, (LPVOID)byPage, KPAGE, NULL)){/*printf("Read Memory error!!!\n");*/return TRUE;}DWORD *pdwPointer = NULL;pdwPointer = (DWORD *)byPage;for (DWORD i = 0; i < KONEK; i++){if (*pAddrListCounter >= addrListMax){/*printf("Too many data, can not save...\n");*/QMessageBox::information(NULL, "提示", "Too many data, can not save...", QMessageBox::Yes);return FALSE;}if (pdwPointer[i] == dwValue){pAddrList[*pAddrListCounter] = dwBaseAddr + i * sizeof(DWORD);ui.tableWidget_2->setRowCount(row + 1);//设置行数QString temp = QString::number(pAddrList[*pAddrListCounter], 16);ui.tableWidget_2->setItem(row, 0, new QTableWidgetItem(temp.toUpper()));//转大写//ui.tableWidget_2->setItem(row, 0, new QTableWidgetItem(QString::number(pAddrList[*pAddrListCounter],16)));//从DWORD转为QString//qDebug() << pAddrList[*pAddrListCounter];(*pAddrListCounter)++;row++;}}return TRUE;
}

5.第一回合对比

void QtModifer::FirstRound(HANDLE hProcess, DWORD dwValue, DWORD *pAddrList, DWORD *pAddrListCounter, const DWORD addrListMax)
{DWORD dwBaseAddr = 64 * KONEK;DWORD dwPageCount = (2 * KONEG - 64 * KONEK * 2) / KPAGE;/*printf("%u pages\n", dwPageCount);printf("Start searching ...\n");*/DWORD dwBeginAddr = dwBaseAddr;for (; dwBaseAddr < 2 * KONEG - 64 * KONEK; dwBaseAddr += KPAGE){if (!CompareOnePage(hProcess, dwBaseAddr, dwValue, pAddrList, pAddrListCounter, addrListMax)){return;}计算进度百分比DWORD page = (dwBaseAddr - dwBeginAddr) / KPAGE + 1;//printf("current is %u page\n", page);//double temp = ((double)page / dwPageCount) * 100;//printf("-----%%%f------\n", temp);ui.progressBar->setMinimum(0);ui.progressBar->setMaximum(dwPageCount);ui.progressBar->setValue(page);}/*printf("\nSearch finished...\n");*//*system("pause");*/
}

6.第一次查找（这里是查找要改的那个值，比如：分数）

void QtModifer::searchBtnClicked()
{DWORD dwSearchValue = 0;dwAddrList[4 * KONEK] = { 0 };dwAddrCount = 0;QString temp = ui.lineEdit_search->text();dwSearchValue = temp.toInt();FirstRound(hProcess, dwSearchValue, dwAddrList, &dwAddrCount, 4 * KONEK);}

7.第二回合对比

void QtModifer::SecondRound(HANDLE hProcess, DWORD dwValue, DWORD * pAddrList, DWORD dwAddrListCounter, DWORD * pTargetList, DWORD * pTargetCounter)
{DWORD dwTemp = 0;row = 0;for (DWORD i = 0; i < dwAddrListCounter; i++){if (ReadProcessMemory(hProcess, (LPCVOID)pAddrList[i], &dwTemp, sizeof(dwTemp), NULL)){if (dwTemp == dwValue){pTargetList[*pTargetCounter] = pAddrList[i];ui.tableWidget_2->setRowCount(row + 1);//设置行数ui.tableWidget_2->setItem(row, 0, new QTableWidgetItem(QString::number(pTargetList[*pTargetCounter], 16)));//从DWORD转为QString(*pTargetCounter)++;row++;}}}
}

8.第二轮查找

void QtModifer::researchBtnCliked()
{/*ui.tableWidget_2->clearContents();*/DWORD dwSecondRoundSearchValue = 0;dwTargetList[KONEK] = { 0 };dwTargetCounter = 0;QString temp = ui.lineEdit_search->text();dwSecondRoundSearchValue = temp.toInt();SecondRound(hProcess, dwSecondRoundSearchValue, dwAddrList, dwAddrCount, dwTargetList, &dwTargetCounter);/*ShowAddrList(dwTargetList, dwTargetCounter);*/
}

9.修改功能

void QtModifer::modifyBtnClicked()
{BOOL bRet = FALSE;DWORD value;QString temp = ui.lineEdit_modify->text();value = temp.toInt();for (DWORD i = 0; i < dwTargetCounter; i++){bRet = WriteProcessMemory(hProcess, (LPVOID)dwTargetList[i], &value, sizeof(value), NULL);if (bRet){/*printf("Edit Success!!!\n");*/QMessageBox::information(NULL, "提示", "edit Success!!!", QMessageBox::Yes);}else{QMessageBox::information(NULL, "提示", "edit fail!!!", QMessageBox::Yes);}}
}

10.全部.cpp代码

#include "QtModifer.h"

11.main函数

#include "QtModifer.h"
#include <QtWidgets/QApplication>int main(int argc, char *argv[])
{QApplication a(argc, argv);QtModifer w;w.show();return a.exec();
}

运行界面

使用方法：

1.先打开贪吃蛇游戏（也可以用其他小游戏，一般来说选自己做的，因为免得打不开）。
2.运行程序，点击刷新按钮。
3.鼠标选择贪吃蛇程序，点击打开按钮。
4.将贪吃蛇游戏玩到分数等于10（也可以是其他分数），在第一个输入框输入10，点击查找按钮。
5.再将贪吃蛇游戏玩到20（也可以是其他的，但是要跟第一次查找的分数不一样），点击二次查找按钮。
6.再第二个输入框输入想要改变的值，比如我这里想把分数改为10000.点击修改按钮。
7.再玩一下贪吃蛇游戏，发现分数改变，修改成功。
8.注意：我的贪吃蛇是按空格可以暂停的，修改之后，再按空格就会继续运行。

该项目还有很多不足，望指正共勉！
