根据上一篇 使用Python读写游戏1 中,使用Python win32库,对一款游戏进行了读内存 操作。
今天来写一下对内存进行写的操作
要进行32位的读写,首先了解一下要用到的几个函数,通过百度找到的,大多都是C/C++的资料。
更详细的分析看上一篇。
写入函数 是 WriteProcessMemory
此函数能写入某一进程的内存区域(直接写入会出Access Violation错误,故需此函数)。
VC++声明
BOOL WriteProcessMemory(
HANDLE hProcess,//要修改的进程内存的句柄。句柄必须具有对进程的进程_vm_写和进程_vm_操作的访问权限
LPVOID lpBaseAddress,//指向写入数据的指定进程中的基地址的指针。在进行数据传输之前,系统将验证指定大小的基址和内存中的所有数据都可用于写访问,如果无法访问,则函数将失败。
LPVOID lpBuffer,//指向缓冲区的指针,其中包含要在指定进程的地址空间中写入的数据
DWORD nSize,//要写入指定进程的字节数。
LPDWORD lpNumberOfBytesWritten//指向接收传输到指定进程的字节数的变量的指针。此参数是可选的。如果lpNumberOfBytesWritten是零,则忽略该参数。
如果函数成功,则返回值为非零
如果函数失败,则返回值为0(零)。若要获取扩展错误信息,请调用GetLastError,如果请求的写操作跨入进程中无法访问的区域,则函数将失败。
对单机植物大战僵尸进行读取与写入操作
对植物大战僵尸分析,请看
首先是对阳光数量的读取
阳光的基址偏移是:
阳光:PlantsVsZombies.exe+2A9EC0+768+5560
不能直接读PlantsVsZombies.exe+2A9EC0,所以把该值添加到CE中,查看地址栏中的十六进制值 006A9EC0

ret2 = GetProcssID(ret+0x768,4)

print ("阳光的数量:%d" % sun)
#sun = GetProcssID(GetProcssID(GetProcssID(0x006A9EC0, 4)+0x768, 4)+0x5560, 4)
根据之前的分析,植物大战僵尸可以开启自动收集功能。具体的地址是
自动收集:PlantsVsZombies.exe+3158B 初始值:5274496 修改后:22051712
十六进制:0043158B
声明一个函数
def WriteMemeryInt(_address,Data):
hGameHandle = win32api.OpenProcess(PROCESS_ALL_ACCESS, False, pid)
WriteProcessInt = kernel32.WriteProcessMemory // 从kernel32动态链接库中调用这个函数
WriteProcessInt(int(hGameHandle),_address,ctypes.byref(ctypes.c_ulong(Data)),4,None)
return Data
代码分析:
WriteProcessInt(int(hGameHandle),_address,ctypes.byref(ctypes.c_ulong(Data)),4,None)
BOOL WriteProcessInt(
int(hGameHandle), //传入的句柄
_address, //要写入的地址
ctypes.byref(ctypes.c_ulong(Data)), //要写入的数据
4, //要写入指定进程的字节数。
None //指向接收传输到指定进程的字节数的变量的指针。此参数是可选的。如果lpNumberOfBytesWritten是零,则忽略该参数。

基本代码就这些了,接下来按照我写C的格式,把代码格式改一下,因为看起来真的挺乱的
先把FindWindow 等基础操作用函数给封装
# -*- coding: utf-8 -*-
import win32process#进程模块
from win32con import PROCESS_ALL_ACCESS #Opencress 权限
import win32api#调用系统模块
import ctypes#C语言类型
from win32gui import FindWindow#界面
kernel32 = ctypes.windll.LoadLibrary("kernel32.dll")
GetLastError = kernel32.GetLastError
def _GetProcessId(className,windowName):
hGameWindow = FindWindow(className, windowName)
pid = win32process.GetWindowThreadProcessId(hGameWindow)[1]
return pid
def _GetPorcessHandle(pid):
hGameHandle = win32api.OpenProcess(PROCESS_ALL_ACCESS, False, pid)
return hGameHandle
def _ReadMemeryInt(hGameHandle,_address,bufflength):
addr = ctypes.c_ulong()
ReadProcessInt = kernel32.ReadProcessMemory
ReadProcessInt(int(hGameHandle), _address, ctypes.byref(addr), bufflength, None)
return addr.value
def WriteMemeryInt(hGameHandle,_address,Data):
WriteProcessInt = kernel32.WriteProcessMemory
WriteProcessInt(int(hGameHandle),_address,ctypes.byref(ctypes.c_ulong(Data)),4,None)
return Data
def main():
ProcessId = _GetProcessId(None,u"植物大战僵尸中文版")
_hGameHandle = _GetPorcessHandle(ProcessId)
win32api.CloseHandle(_hGameHandle)
if __name__ == '__main__':
main()
在开始写功能,先是读取阳光数量和修改阳光数量:
def _modifySunshine(hGameHandle):
sun = _ReadMemeryInt(hGameHandle,_ReadMemeryInt(hGameHandle,_ReadMemeryInt(hGameHandle,0x006A9EC0, 4) + 0x768, 4) + 0x5560, 4)
sun_write = WriteMemeryInt(hGameHandle,_ReadMemeryInt(hGameHandle, _ReadMemeryInt(hGameHandle, 0x006A9EC0, 4) + 0x768,4) + 0x5560, 100)
print("修改前阳光的数量:" , sun)
if sun_write:
print("###################修改阳光数量成功##############################")
sun = _ReadMemeryInt(hGameHandle,_ReadMemeryInt(hGameHandle, _ReadMemeryInt(hGameHandle, 0x006A9EC0, 4) + 0x768,4) + 0x5560, 4)
print("修改后的阳光数量:", sun)
else:
print("###################修改阳光数量失败,错误信息:##################",GetLastError)
接着,根据分析,有自动收集阳光功能,基址是:
自动收集:PlantsVsZombies.exe+3158B 初始值:5274496 修改后:22051712
十六进制:0043158B
def _collectSunshine(hGameHandle):
collect = WriteMemeryInt(hGameHandle,0x0043158B,22051712)
if collect:
print("###################启动自动收集功能成功#########################")
else:
print("###################修改自动收集功能失败,错误信息:##################",GetLastError)
接下来是秒杀功能,因为不一定每次都守得住
普通僵尸秒杀基址:
秒杀普通僵尸: PlantsVsZombies.exe+13178A 初始值:1284214911 修改后:1284214928
十六进制:0053178A
def _Seckill(hGameHandle):
seckill = WriteMemeryInt(hGameHandle,0x0053178A,1284214928)
if seckill:
print("###################启动秒杀普通僵尸功能成功#########################")
else:
print("###################修改秒杀功能失败,错误信息:#########################",GetLastError)
除了普通僵尸,还有头盔僵尸:
头盔僵尸基址:
秒杀带护甲: PlantsVsZombies.exe+13186D 初始值:1347618942 修改后:1347653776
十六进制:0053186D
def _SecKillHelmet(hGameHandle):
seckillHelemet = WriteMemeryInt(hGameHandle,0x53186D ,1347653776)
if seckillHelemet:
print("###################启动秒杀头盔僵尸功能成功#########################")
else:
