python - PyAutoGui 类型错误 : cannot unpack non-iterable NoneType object

Question

    import pyautogui
import cv2
import time
while(True):
    TradeFrom = pyautogui.locateCenterOnScreen("Screenshot_256.png", grayscale= True, confidence=0.9)
    TradeTo = pyautogui.locateCenterOnScreen("Screenshot_258.png", grayscale=True, confidence=0.9)
    if TradeFrom == None:
        if TradeTo == None:
           time.sleep(30)
           continue
        elif TradeTo != None:
           z,t=TradeFrom
           pyautogui.moveTo(z,t,3)
           pyautogui.rightClick()
           #TODO ÇOK YAPILACAK ŞEY VAR AMK
    else:
        x,y = TradeTo
        pyautogui.moveTo(x,y,3)
        pyautogui.rightClick()
        InviteToParty = pyautogui.locateCenterOnScreen("InviteToParty.png", grayscale= True, confidence=0.9)
        Invite_X,Invite_Y = InviteToParty
        pyautogui.moveTo(Invite_X,Invite_Y)

准确输出:

Traceback (most recent call last):
  File "C:/Users/emosc/PycharmProjects/heuheu/main.py", line 12, in <module>
    z,t=TradeFrom
TypeError: cannot unpack non-iterable NoneType object

如果我将 TradeFrom 和 TradeTo 放在 while 循环之外，它工作得很好，任何人都可以解释为什么我将其放入 while 循环后它会崩溃吗？

我认为你需要修复逻辑。现在您正在屏幕上寻找两个对象。您的声明是说，如果找不到第一个对象但找到第二个对象，则从第一个对象分配坐标...这是 None ，这就是您的代码失败的原因。不确定预期的结果是什么，但也许可以尝试一下:

import pyautogui
import cv2
import time
while(True):
    TradeFrom = pyautogui.locateCenterOnScreen("Screenshot_256.png", grayscale= True, confidence=0.9)
    TradeTo = pyautogui.locateCenterOnScreen("Screenshot_258.png", grayscale=True, confidence=0.9)
    if TradeFrom == None:
        if TradeTo == None:
           time.sleep(30)
           continue
        elif TradeTo != None:
           z,t=TradeTo
           pyautogui.moveTo(z,t,3)
           pyautogui.rightClick()
           #TODO ÇOK YAPILACAK ŞEY VAR AMK
    else:
        x,y = TradeFrom
        pyautogui.moveTo(x,y,3)
        pyautogui.rightClick()
        InviteToParty = pyautogui.locateCenterOnScreen("InviteToParty.png", grayscale= True, confidence=0.9)
        Invite_X,Invite_Y = InviteToParty
        pyautogui.moveTo(Invite_X,Invite_Y)

此外，我建议您使用中断键进行编码，这样很容易中断此循环
