Tkinter制作的GTA SA刷钱GUI点击按钮后崩溃问题求助

问题描述 #

用Python和Tkinter制作了《GTA：圣安地列斯》的刷钱菜单，点击刷钱按钮后能成功修改金钱，但GUI会直接崩溃；尝试点击停止按钮时触发如下报错：

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Users\####\AppData\Local\Programs\Python\Python310\lib\tkinter\__init__.py", line 1921, in __call__
    return self.func(*args)
  File "C:\Users\####\PycharmProjects\gtasa\main.py", line 17, in moneygive
    process.write(moneypointer, 99999999999)
  File "C:\Users\####\PycharmProjects\gtasa\venv\lib\site-packages\ReadWriteMemory\__init__.py", line 125, in write
    ctypes.windll.kernel32.WriteProcessMemory(self.handle, lp_base_address, lp_buffer,

问题根源 #

• Tkinter是单线程框架，主事件循环负责处理所有GUI交互和界面更新。moneygive函数中的while 1死循环会完全阻塞主循环，导致GUI失去响应甚至崩溃。
• 强制停止程序时，未完成的process.write操作被中断，触发系统级的内存写入异常。

解决方案 #

1. 用threading模块将刷钱逻辑放到独立线程中，避免阻塞GUI主循环
2. 增加全局变量控制线程启停，实现平滑的开始/停止操作
3. 给刷钱循环添加延迟，减少不必要的资源占用

修改后的完整代码 #

from ReadWriteMemory import ReadWriteMemory
from tkinter import *
import threading
import time

rwm = ReadWriteMemory
process = rwm().get_process_by_name(process_name="gta-sa.exe")
process.open()

# Money
baseaddress = 0x1F0000 + 0x118FD8
moneypointer = process.get_pointer(baseaddress, offsets=[0xB8]) 

# 控制线程运行的全局变量
running = False

def moneygive():
    global running
    running = True
    while running:
        process.write(moneypointer, 999999999)
        time.sleep(0.1)  # 每0.1秒写入一次，减少资源占用

def stop_money():
    global running
    running = False

root = Tk()
root.title("GTA San Andreas Menu")
root.iconbitmap()
root.geometry("200x200")

# 开始刷钱按钮
start_btn = Button(root, text="无限刷钱!", padx=50, command=lambda: threading.Thread(target=moneygive, daemon=True).start())
start_btn.pack(pady=10)

# 停止刷钱按钮
stop_btn = Button(root, text="停止刷钱", padx=50, command=stop_money)
stop_btn.pack(pady=10)

root.mainloop()

关键说明 #

• 使用threading.Thread创建守护线程运行刷钱逻辑，daemon=True确保程序退出时线程自动终止
• 通过running全局变量控制循环启停，避免强制中断导致的写入异常
• 添加time.sleep(0.1)降低写入频率，既保证刷钱效果，又减少对系统资源的消耗
