多处理暂停 1 个代码而另一个处于活动状态？

Question

我正在为点击游戏制作一个机器人，该游戏有随机弹出的广告。使用下面的代码，只要检测到这些弹出窗口，它们就会被关闭。但是，播放唱首歌游戏的代码是定时的，每当发现广告时，它就会扰乱代码，使程序失败。有谁知道每当 ad() 找到什么东西时可以暂停 play() 中发生的事情吗？

我的代码：

from pyautogui import * 
import pyautogui 
import time 
import keyboard 
import random
import win32api, win32con
from multiprocessing import Process
import sys

def ad():
    adloop = True
    while adloop:
        cross = pyautogui.locateOnScreen('image.png', confidence = 0.95)        
        if cross != None:
            print("Popup!")
        else:
            print("Checking for popups...")

def count():
    amount = 0
    count = True
    while count:
        amount += 1
        print(amount)
        time.sleep(1)


if __name__=='__main__':
        p1 = Process(target = ad)
        p1.start()
        p2 = Process(target = count)
        p2.start()

您可以使用 Process.Event 作为标志。

注意操作需要pip install pyautogui pillow opencv-python

import pyautogui
import time
from multiprocessing import Process,Event

def ad(e):
    adloop = True
    while adloop:
        cross = pyautogui.locateOnScreen('image.png', confidence = 0.95)
        if cross != None:
            print("Popup!")
            e.clear()
        else:
            print("Checking for popups...")
            e.set()

def count(e):
    amount = 0
    while True:
        e.wait()  # sleep process when event is clear.
        amount += 1
        print(amount)
        time.sleep(1)

if __name__=='__main__':
    # Create an event to share between the processes.
    # When set, the counting process will count.
    e = Event()
    e.set()

    # Make processes daemons, so exiting main process will kill them.
    p1 = Process(target = ad, args=(e,), daemon=True)
    p1.start()
    p2 = Process(target = count, args=(e,), daemon=True)
    p2.start()
    input('hit ENTER to exit...')

输出：

hit ENTER to exit...1
Checking for popups...
2
Checking for popups...
Checking for popups...
3
Checking for popups...
4
Checking for popups...
Popup!
Popup!
Popup!
Popup!
Popup!
Popup!
Popup!
Popup!
Checking for popups...
5
Checking for popups...
6
Checking for popups...
