python實現對單機游戲內存修改

以植物大戰僵屍為例：

用到的工具：spy2.7 用於讀取窗口的文件句柄。Cheat Engine6.5這個工具用於讀取內存地址

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

PROCESS_ALL_ACCESS=(0x000F0000|0x00100000|0xFFF) 
window=win32gui.FindWindow("MainWindow","植物大戰僵屍") 
hid,pid=win32process.GetWindowThreadProcessId(window) #根據窗體抓取進程編號
phand=win32api.OpenProcess(PROCESS_ALL_ACCESS,False,pid)#用最高權限打開進程編號
date=ctypes.c_long()#C語言的整數類型，讀取數據
mydll=ctypes.windll.LoadLibrary("C:\\Windows\\System32\\kernel32.dll")#加載內核模塊

while  True:
    mydll.ReadProcessMemory(int(phand), 244866760, ctypes.byref(date), 4, None)  # 讀取內存,244866760是內存地址
    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)
