常规项目

根据变量的变化使用CE寻找,找到之后再通过指针扫描寻找可用的基址

阳光 内存实际值=游戏显示值

智慧树高度 内存实际值=游戏显示值

金钱 内存实际值=游戏显示值/10

花肥,杀虫剂,巧克力,树肥 内存实际值=游戏显示值+1000

关键函数

enum Type {
    Sunlight, Money, TreeHeight, Chocolate, TreeFood, FlowerFood, Insecticide
};

//定义映射表用于保存各项偏移值
unsigned int offsetTable[10] = { 0x5578,0x50,0x11c,0x250,0x258,0x220,0x224 };

//获取某些项目的值
unsigned int getSomething(HANDLE handle, DWORD BaseAddr,unsigned int type) {
    unsigned int num = 0;
    DWORD addr = BaseAddr + 0x00355E0C;
    ReadProcessMemory(handle, addr, &addr, sizeof(DWORD), NULL);
    if (type == Sunlight) 
        addr += 0x868;
    else
        addr += 0x950;
    ReadProcessMemory(handle, (LPVOID)addr, &addr, sizeof(DWORD), NULL);
    addr += offsetTable[type];
    ReadProcessMemory(handle, (LPVOID)addr, &num, sizeof(DWORD), 0);
    return num;
}

//设置某些项目的值
void setSomething(HANDLE handle, DWORD BaseAddr,unsigned int type, unsigned int num) {
    DWORD addr = BaseAddr + 0x00355E0C;
    ReadProcessMemory(handle, addr, &addr, sizeof(DWORD), NULL);
    if (type == Sunlight)
        addr += 0x868;
    else
        addr += 0x950;
    ReadProcessMemory(handle, (LPVOID)addr, &addr, sizeof(DWORD), NULL);
    addr += offsetTable[type];
    WriteProcessMemory(handle, (LPVOID)addr, &num, sizeof(DWORD), 0);
}

卡槽植物

十个卡槽,每个卡槽对应一个植物,可以在坚果保龄球2中根据卡槽1(最左边的卡槽)的坚果变化来找到卡槽的地址,之后再寻找基址

具体方法: 初值未知,如果卡槽1的植物和新的卡槽1(原卡槽2)的植物相同,则扫不变的值,否则扫变化的值

卡槽之间的偏移可以通过浏览卡槽1内存区域看出,为0x50

坚果植物卡槽编号:

普通坚果 3

爆炸坚果 49

巨型坚果 50

设置卡槽植物函数

//设置卡槽植物
BOOL SetPlantCard(HANDLE hProcess,DWORD BaseAddr,DWORD nCard,DWORD plantType) {
    DWORD cardAddr = BaseAddr + 0x355E0C;
    ReadProcessMemory(hProcess, cardAddr, &cardAddr, sizeof(DWORD), NULL);
    cardAddr += 0x868;
    ReadProcessMemory(hProcess, cardAddr, &cardAddr, sizeof(DWORD), NULL);
    cardAddr += 0x15C;
    ReadProcessMemory(hProcess, cardAddr, &cardAddr, sizeof(DWORD), NULL);
    cardAddr += 0x5C+nCard*0x50;//卡槽偏移
    return WriteProcessMemory(hProcess, cardAddr, &plantType, sizeof(DWORD), NULL);
}

种植无冷却

具体方法: 仅针对一个卡槽,初始值未知,种植后持续变化,冷却完毕后不变,反复扫描并查找基址,查看对应内存区域再对照植物编号可以发现卡槽间的偏移为0x50

冷却特点: 可种植状态冷却值为0,种植后冷却值持续增长,到达冷却上限后,冷却值清零,植物重新可种植

注意: 直接将冷却值置0会导致无法种植

修改方法:

  1. 修改冷却结束后恢复的速度,将inc指令修改为mov一个较大值 这个
  2. 直接跳转到冷却值和冷却上限比较成功的函数

以方法2为例

7E 16 对应汇编指令为 jle 0x18

修改为jmp $+2 即 eb 00 (相对当前指令2字节后的指令)

直接执行冷却值达到冷却上限后的函数(冷却值清零,植物冷却完毕可种植)

关键代码

//修改进程代码区代码 参数: 进程句柄 修改代码起始地址 硬编码指针 代码字节数
BOOL WriteProcessCodeMemory(HANDLE hProcess, LPVOID lpStartAddress, LPCVOID lpBuffer, SIZE_T nSize) {
    DWORD dwOldProtect;
    //取消页保护
    if (!VirtualProtectEx(hProcess, lpStartAddress, nSize, PAGE_EXECUTE_READWRITE, &dwOldProtect)) {
        return FALSE;
    }
    BOOL bResult = WriteProcessMemory(hProcess, lpStartAddress, lpBuffer, nSize, NULL);//写入代码
    VirtualProtectEx(hProcess, lpStartAddress, nSize, dwOldProtect, &dwOldProtect);//开启页保护
    return bResult;
}

//无限冷却
BOOL Uncooled(HANDLE hProcess, DWORD BaseAddr) {
    unsigned char code[2] = { 0xeb,0x00 };
    return WriteProcessCodeMemory(hProcess, BaseAddr + 0x9ce02, code, 2);//jle 0x18修改为jmp $+2
}

//恢复冷却
BOOL RecoveryCooling(HANDLE hProcess, DWORD BaseAddr) {
    unsigned char OriginalCode[2] = { 0x7E ,0x16 };//jmp $+2恢复为jle 0x18
    return WriteProcessCodeMemory(hProcess, BaseAddr + 0x9ce02, OriginalCode, 2);
}

无限阳光

前文已经给出了阳光的地址 基址为0x355E0C 偏移+868 +5578

查找对阳光修改的代码即可

阳光减少代码

阳光增加代码

image

基本过程:

  1. 设置阳光值为9999

  2. 修改阳光减少代码使得种植物不消耗阳光

  3. 修改阳光增加代码使得阳光不变化(防止阳光过多导致溢出)

//修改进程代码区代码 参数: 进程句柄 修改代码起始地址 硬编码指针 代码字节数
BOOL WriteProcessCodeMemory(HANDLE hProcess, LPVOID lpStartAddress, LPCVOID lpBuffer, SIZE_T nSize) {
    DWORD dwOldProtect;
    //取消页保护
    if (!VirtualProtectEx(hProcess, lpStartAddress, nSize, PAGE_EXECUTE_READWRITE, &dwOldProtect)) {
        return FALSE;
    }
    BOOL bResult = WriteProcessMemory(hProcess, lpStartAddress, lpBuffer, nSize, NULL);//写入代码
    VirtualProtectEx(hProcess, lpStartAddress, nSize, dwOldProtect, &dwOldProtect);//开启页保护
    return bResult;
}
//无限阳光,锁定阳光为9999
BOOL UnlimitedSun(HANDLE hProcess, DWORD BaseAddr) {
    unsigned char Code[3] = { 0x29,0xdb,0 };//cmp ebx,eax 修改为sub ebx,ebx   and ecx,0x32修改为and ecx,0
    BOOL flag;
    flag = setSomething(hProcess, BaseAddr, Sunlight, 9999);//修改阳光
    flag &= WriteProcessCodeMemory(hProcess, BaseAddr + 0x27690, Code, 2);//修改阳光减少代码
    flag &= WriteProcessCodeMemory(hProcess, BaseAddr + 0x3C0AB, &Code[2], 1);//修改阳光增加代码
    return flag;
}

//恢复阳光消耗
BOOL RecoverySunConsume(HANDLE hProcess, DWORD BaseAddr) {
    unsigned char OriginalCode[3] = { 0x3B,0xD8,0x32 };//sub ebx,ebx恢复为cmp ebx,eax and ecx,0恢复为and ecx,0x32
    BOOL flag = WriteProcessCodeMemory(hProcess, BaseAddr + 0x27690, OriginalCode, 2);//恢复阳光减少代码
    flag &= WriteProcessCodeMemory(hProcess, BaseAddr + 0x3C0AB, &OriginalCode[2], 1);//恢复阳光增加代码
    return flag;
}

浓雾透视

基本原理

具体方法: 在生存模式浓雾进行,初值未知,通过在雾区种植和铲除路灯花引起的变化来判断,最终可以发现是4字节数据,数值代表雾的浓度,255代表浓雾,0代表没雾,再查找修改雾值的代码

寻找浓雾地址

image

浓雾修改代码

mov [ecx],edx这行代码修改了雾值,可以改为mov [ecx],0

注意硬编码为0xc7,0x01,0x00,0x00,0x00,0x00 由于较长无法直接修改代码,所以这里选择使用hook技术

image

HOOK

hook的基本过程

  1. 读取并保存目的地址原始代码
  2. 申请空间(PVZ游戏进程空间)用于存储原始代码 hook代码 jmp返回代码
  3. 向申请的空间中写入原始代码 hook代码 jmp返回代码
  4. 修改目的地址的代码为jmp HookCode
  5. 返回HookCode首地址 用于解除hook

值得一提的是jmp指令后跟的偏移值是以jmp的下一条指令首地址计算

jmp指令偏移值=目的地址-(jmp指令首地址+5) 这里的5是jmp指令本身的长度 +5便是下一条指令

offset=desAddr-(jmpAddr+5)

//修改进程代码区代码 参数: 进程句柄 修改代码起始地址 硬编码指针 代码字节数
BOOL WriteProcessCodeMemory(HANDLE hProcess, LPVOID lpStartAddress, LPCVOID lpBuffer, SIZE_T nSize) {
    DWORD dwOldProtect;
    //取消页保护
    if (!VirtualProtectEx(hProcess, lpStartAddress, nSize, PAGE_EXECUTE_READWRITE, &dwOldProtect)) {
        return FALSE;
    }
    BOOL bResult = WriteProcessMemory(hProcess, lpStartAddress, lpBuffer, nSize, NULL);//写入代码
    VirtualProtectEx(hProcess, lpStartAddress, nSize, dwOldProtect, &dwOldProtect);//开启页保护
    return bResult;
}

//hook指定地址,申请新空间保存原始代码并写入hookcode,返回申请空间的地址
LPVOID SetHook(HANDLE hProcess, LPVOID desAddr, LPCVOID hookCode, SIZE_T hookCodeSize, SIZE_T origCodeSize) {
    BYTE origCode[10] = { 0 }, jmpCode[5] = { 0xE9,0,0,0,0 };
    //1. 读取并保存原始代码
    if (!ReadProcessMemory(hProcess, desAddr, origCode, origCodeSize, NULL))
        return NULL;

    //2. 申请空间用于存储原始代码,hook代码,jmp返回代码
    LPVOID allocAddr = VirtualAllocEx(hProcess, NULL, hookCodeSize + origCodeSize + 5, MEM_COMMIT | MEM_RESERVE, PAGE_EXECUTE_READWRITE);
    if (!allocAddr)
        return NULL;

    //3. 向申请空间写入原始代码,hook代码,jmp返回代码  jmp xxx 偏移为目的地址-jmp下一条指令地址
    *(DWORD*)(jmpCode + 1) = (DWORD)desAddr + 5 - ((DWORD)allocAddr + hookCodeSize + origCodeSize + 5);//hook返回地址的偏移
    if (!WriteProcessCodeMemory(hProcess, allocAddr, origCode, origCodeSize)                      //写入原始代码
        || !WriteProcessCodeMemory(hProcess, (DWORD)allocAddr + origCodeSize, hookCode, hookCodeSize)//写入hook代码
        || !WriteProcessCodeMemory(hProcess, (DWORD)allocAddr + origCodeSize + hookCodeSize, jmpCode, 5))//写入jmpcode
    {
        VirtualFreeEx(hProcess, allocAddr, 0, MEM_RELEASE);//写入失败则释放空间
        return NULL;
    }

    //4. 修改目的地址处的代码  jmp xxx偏移 原始代码后才是需要执行的hook代码
    *(DWORD*)(jmpCode + 1) = ((DWORD)allocAddr + origCodeSize) - ((DWORD)desAddr + 5);
    WriteProcessCodeMemory(hProcess, desAddr, jmpCode, 5);//在源地址处写入跳转代码
    if (origCodeSize > 5)//原始代码长度大于5时nop多余字节
    {
        BYTE nopCode[5] = { 0x90,0x90,0x90,0x90,0x90 };
        if (!WriteProcessCodeMemory(hProcess, (DWORD)desAddr + 5, nopCode, origCodeSize - 5))
        {
            VirtualFreeEx(hProcess, allocAddr, 0, MEM_RELEASE);//写入nopcode失败则释放空间并返回
            return NULL;
        }
    }

    //5. hook成功则返回hookCode所在地址
    return allocAddr;
}

//取消hook指定地址,写回原始代码并释放申请空间
BOOL UnHook(HANDLE hProcess, LPVOID desAddr, SIZE_T origCodeSize, LPVOID allocAddr) {
    BYTE origCode[10] = { 0 };
    //1. 从申请空间中读出原始代码
    if (!ReadProcessMemory(hProcess, allocAddr, origCode, origCodeSize, NULL))
        return FALSE;
    //2. 将原始代码写回目的地址
    if (!WriteProcessCodeMemory(hProcess, desAddr, origCode, origCodeSize))
        return FALSE;
    //3. 释放申请空间
    if (!VirtualFreeEx(hProcess, allocAddr, 0, MEM_RELEASE))
        return FALSE;
    return TRUE;
}

除雾代码

//除雾 注意保留hook代码首地址
LPVOID DeFogByHook(HANDLE hProcess, LPVOID BaseAddr) {

    unsigned char hookCode[9] = {
        0xc7,0x01,0x00,0x00,0x00,0x00,  //mov [ecx],0
        0x83,0xc1,0x04                  //add ecx,0x4
    };
    //写入hook代码进行hook
    return SetHook(hProcess, (DWORD)BaseAddr + 0x26173, hookCode, sizeof(hookCode), 5);
}

//恢复雾
BOOL RecoveryFogByUnHook(HANDLE hProcess, LPVOID BaseAddr, LPVOID allocAddr) {
    return UnHook(hProcess, (DWORD)BaseAddr + 0x26173, 5, allocAddr);
}

hook前 指令为mov [ecx],edx add ecx,04

image

hook后 指令被修改为jmp

hookcode 新分配空间前5个字节正是原始代码 之后是hook代码和jmp返回代码

种植植物

基本原理

程序是执行种植植物的函数后再执行增加植物数量的功能

首先查找草坪上的植物数量,初值0,随着种植个数增加 基址0x355E0C 偏移+868 +D4

再查找是什么修改了植物数量,下断点之后再种植一个植物

断下后查看调用堆栈中的返回地址,即可找到种植函数

![9.1 找到种植call函数](9.1 找到种植call函数.png)

这个功能最初使用远程线程注入dll来实现,注入dll虽然比较简单但是却并不通用,在此仅做介绍,比较推荐使用远程代码注入的方式实现

远程线程注入dll函数

远程线程是当前进程在目标进程中创建一个线程并执行特定代码(这段代码必须在目标进程中而不是当前进程中)

注入dll是因为dll在被进程或线程加载时执行dll的DllMain函数,通过这一特点我们可以实现一些特殊功能

优点: 便于实现

缺点: dll注入容易被检测到

基本过程:

  1. 打开进程获取进程句柄
  2. 在目标进程中申请空间用于存储dll路径名
  3. 将dll路径名写入申请的空间中
  4. 创建远程线程,执行LoadLibrary函数(加载dll)
  5. 目标进程加载dll后自动执行dll的DllMain函数
//创建远程线程方式向指定进程注入dll
BOOL InjectDllByRemoteThread(DWORD desProcId,WCHAR* dllPath) {
    //打开进程获取进程句柄
    HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, desProcId);
    if (!hProcess)
        return FALSE;

    //申请空间
    DWORD pathSize = (wcslen(dllPath) + 1) * 2; 
    LPVOID newMemAddr = VirtualAllocEx(hProcess, 0, pathSize, MEM_COMMIT, PAGE_READWRITE);
    if (!newMemAddr)
        return FALSE;

    //写入dll路径
    if (!WriteProcessMemory(hProcess, newMemAddr, dllPath, pathSize, NULL))
    {
        VirtualFreeEx(hProcess, newMemAddr, 0, MEM_RELEASE);
        return FALSE;
    }
       
    //创建远程线程
    HANDLE hThread = CreateRemoteThread(hProcess, NULL, 0, (LPTHREAD_START_ROUTINE)LoadLibraryW, newMemAddr, 0, NULL);
    if (!hThread)
    {
        VirtualFreeEx(hProcess, newMemAddr, 0, MEM_RELEASE);
        return FALSE;
    }

    WaitForSingleObject(hThread, INFINITE);//等待线程信号,保证成功注入

    //回收资源
    VirtualFreeEx(hProcess, newMemAddr, 0, MEM_RELEASE);
    CloseHandle(hThread);
    CloseHandle(hProcess);

    //返回成功
    return TRUE;
}

远程线程卸载dll函数

很多教程只给出了如何注入dll,没有演示如何卸载

如果只注入不卸载会导致下次再注入时不会执行特定函数(由于dll已经被加载过) 不方便实时调试更新dll等问题

基本过程:

  1. 在目标进程申请内存,将需要卸载的dll模块名称写入该内存
  2. 通过枚举模块来查找指定模块
  3. 成功查找到dll模块则创建远程线程执行FreeLibrary函数卸载dll
BOOL UnLoadDllByRemoteThread(DWORD dwProcessId, LPCWSTR lpDllName)
{
    HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwProcessId);
    if (hProcess == NULL)
        return FALSE;

    // 在目标进程中申请一块内存，并将需要卸载的DLL模块的名称写入该内存
    LPVOID lpRemoteDllName = VirtualAllocEx(hProcess, NULL, (wcslen(lpDllName) + 1) * sizeof(WCHAR), MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);
    if (lpRemoteDllName == NULL)
    {
        CloseHandle(hProcess);
        return FALSE;
    }
    if (!WriteProcessMemory(hProcess, lpRemoteDllName, lpDllName, (wcslen(lpDllName) + 1) * sizeof(WCHAR), NULL))
    {
        VirtualFreeEx(hProcess, lpRemoteDllName, 0, MEM_RELEASE);
        CloseHandle(hProcess);
        return FALSE;
    }

    //查找dll模块
    HMODULE hModules[1024],DesModule=NULL;
    DWORD dwSize = 0;
    if (!EnumProcessModules(hProcess, hModules, sizeof(hModules), &dwSize))
    {
        VirtualFreeEx(hProcess, lpRemoteDllName, 0, MEM_RELEASE);
        CloseHandle(hProcess);
        return FALSE;
    }

    // 遍历模块列表，查找需要卸载的DLL模块
    for (DWORD i = 0; i < (dwSize / sizeof(HMODULE)); i++)
    {
        WCHAR szModuleName[MAX_PATH] = { 0 };
        if (GetModuleFileNameExW(hProcess, hModules[i], szModuleName, MAX_PATH) > 0)
        {
            // 获取模块句柄
            if (wcsicmp(szModuleName, lpDllName) == 0)
            {
                DesModule = hModules[i];
            }
        }
    }
    //没有查找到模块
    if (!DesModule) {
        VirtualFreeEx(hProcess, lpRemoteDllName, 0, MEM_RELEASE);
        CloseHandle(hProcess);
        return FALSE;
    }
    // 在目标进程中创建远程线程，执行FreeLibrary函数
    HANDLE hThread = CreateRemoteThread(hProcess, NULL, 0, (LPTHREAD_START_ROUTINE)FreeLibrary, DesModule, 0, NULL);
    if (hThread == NULL)
    {
        VirtualFreeEx(hProcess, lpRemoteDllName, 0, MEM_RELEASE);
        CloseHandle(hProcess);
        return FALSE;
    }

    // 等待线程执行完成
    WaitForSingleObject(hThread, INFINITE);

    // 关闭句柄
    CloseHandle(hThread);
    VirtualFreeEx(hProcess, lpRemoteDllName, 0, MEM_RELEASE);
    CloseHandle(hProcess);

    return TRUE;
}

关键dll函数

这里使用了三种方法

注意: 不要将代码写入switch(reason)之外,否则可能会导致多次执行

#include<windows.h>
#include<stdio.h>

//调用函数
BOOL GrowPlant(DWORD BaseAddr, DWORD x, DWORD y, DWORD TypePlant) {
    LPVOID PlantFunc = BaseAddr + 0x18D70;
    __asm {
        pushad
        push -1         //-1
        push TypePlant   //植物类型
        mov eax, y       //y
        push x           //x
        mov ecx, BaseAddr
        mov ecx, [ecx+0x355E0C]
        mov ecx, [ecx + 0x868]
        push ecx		//植物种植ebp
        call PlantFunc
        popad
    }
    return TRUE;
}


BOOL WINAPI DllMain(HMODULE hInstance, DWORD fdwReason, LPVOID lpReserved) {
    DWORD BaseAddr = GetModuleHandle(NULL);
    DWORD pid = GetCurrentProcessId();
    HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pid);
    LPVOID PlantFunc = BaseAddr + 0x18D70;
    DWORD ebpAddr = BaseAddr+0x355E0C,num=0;
    ReadProcessMemory(hProcess, ebpAddr, &ebpAddr, sizeof(DWORD), NULL);
    ebpAddr += 0x868;
    ReadProcessMemory(hProcess, ebpAddr, &ebpAddr, sizeof(DWORD), NULL);//必须使用带hProcess参数的才能正确读取到地址,NULL不可以
    DWORD x = 1, y = 1, TypePlant = 16;
    
    //注意不要写到switch外,否则可能会一次种多株植物,猜测是dll被多个线程加载导致的
    switch (fdwReason)
    {
    case DLL_PROCESS_ATTACH:    //当进程加载dll模块时执行
        //MessageBoxW(0, L"ProcessAttach!", L"window2", 0);
        //1.直接通过使用ReadProcessMemory函数读取内存获取ebp参数
        __asm {
            pushad
            push - 1         //-1
            push TypePlant   //植物类型
            mov eax, y       //y
            push x           //x
            push  ebpAddr    //ebp
            call PlantFunc   
            popad
        }

        //2.通过利用寄存器获取ebp(推荐)
        x = 3, y = 2, TypePlant = 18;
        __asm {
            pushad
            push - 1         //-1
            push TypePlant   //植物类型
            mov eax, y       //y
            push x           //x
            mov ecx, BaseAddr
            mov ecx, [ecx+0x355E0C]
            mov ecx, [ecx + 0x868]
            push ecx
            call PlantFunc
            popad
        }
       //3. 通过调用函数(推荐)     
        GrowPlant(BaseAddr,7,3,23);         
                     
        break;
    //case DLL_THREAD_ATTACH:        
    //    printf("ThreadAttach!\n");
    //    break;
    //case DLL_THREAD_DETACH:       
    //  if (lpReserved == NULL)
    //    {
    //        FreeLibrary(hInstance);
    //    }
        break;
    case DLL_PROCESS_DETACH:        //当进程卸载dll模块时执行
        MessageBoxW(0, L"ProcessDeTachDll!", L"window2", 0);
        break;
    }
    return TRUE; 
}

失败代码

这是写dll函数时遇到的问题 如果直接用 mov ecx,[BaseAddr+0x355E0C]会导致代码执行失败,推测是这条指令访存过慢所以无效

建议mov ecx,BaseAddr之后通过对寄存器操作达到目的

__asm {
        pushad
        push - 1         //-1
        push TypePlant   //植物类型
        mov eax, y       //y
        push x           //x
        mov ecx,[BaseAddr+ 0x355E0C]//这样不行,推测是访存过慢
        mov ecx,[ecx+0x868]
        mov num, ecx
        push ecx
        call PlantFunc
        popad
    }

远程线程代码注入(推荐)

和远程线程dll注入类似,CreateRemoteThread函数要求的函数原型是

DWORD WINAPI ThreadProc(
  _In_ LPVOID lpParameter//使用CreateThread函数传递的参数 该参数是一个指向其他数据的指针,当然也可以强转为其他类型直接使用
);

基本过程:

  1. 打开进程
  2. 定义注入代码(函数)
  3. 在目标进程中申请空间并写入注入代码
  4. 创建远程线程执行注入代码(函数)
  5. 执行完毕释放空间
//以创建远程线程方式种植植物
BOOL GrowPlantByInjectCode(DWORD dwProcessId,DWORD BaseAddr,DWORD x,DWORD y,DWORD PlantType)
{
    BOOL bSuccess = FALSE;
    //1. 打开进程
    HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwProcessId);    
    if (hProcess != NULL)
    {
        //2. 定义注入代码(函数)

        BYTE InjectCode[50] = {                     //汇编指令              //修正点偏移
            0x55,                                   //0 push ebp
            0x89, 0xE5,                             //1 mov ebp,esp
            0x60,                                   //3 pushad                
            0x68, 0xFF, 0xFF, 0xFF, 0xFF,           //4 push -1           
            0x68, 0x00, 0x00, 0x00, 0x00,           //9 push PlantType        //10

种植僵尸

基本原理

与种植植物思路类似

首先在头脑风暴中通过种植僵尸来找到僵尸数量地址

然后找到僵尸数量增加代码

再通过查看调用堆栈和参数找到种植僵尸call

参数应该也是x y type ebp (注意没有-1)

僵尸种植函数的x值在一个call上方,这个call是个switch结构,没有参数,所以x值也没被修改
