python实现对单机游戏内存修改

以植物大战僵尸为例：

用到的工具：spy2.7 用于读取窗口的文件句柄。Cheat Engine6.5这个工具用于读取内存地址

import win32process 
import win32con
import win32api
import ctypes 
import win32gui 
import time

PROCESS_ALL_ACCESS=(0x000F0000|0x00100000|0xFFF) 
window=win32gui.FindWindow("MainWindow","植物大战僵尸") 
hid,pid=win32process.GetWindowThreadProcessId(window) #根据窗体抓取进程编号
phand=win32api.OpenProcess(PROCESS_ALL_ACCESS,False,pid)#用最高权限打开进程编号
date=ctypes.c_long()#C语言的整数类型，读取数据
mydll=ctypes.windll.LoadLibrary("C:\Windows\System32\kernel32.dll")#加载内核模块

while  True:
    mydll.ReadProcessMemory(int(phand), 244866760, ctypes.byref(date), 4, None)  # 读取内存,244866760是内存地址
    print(date.value)
    if  date.value <300:
        newdata = ctypes.c_long(500)   
        mydll.WriteProcessMemory(int(phand), 244866760, ctypes.byref(newdata), 4, None)
    time.sleep(3)
