PyAutogui：当图像出现时如何停止循环？

如何解决PyAutogui：当图像出现时如何停止循环？

在我的 while 循环中，我想在检测到图像后立即停止但它不起作用（我使用 pyautogui），请对代码提出意见：

# Combat
nike = None
tour = "tour.png"
win = "win.png"
sort = "sort.png"
end = pyautogui.locateOnScreen(win)

while (nike == None):
    try:
     nike = pyautogui.locateOnScreen(tour)
     pyautogui.press("b")
     attack = pyautogui.locateOnScreen("attack.png",confidence=0.7)
     pyautogui.moveto(attack)
     pyautogui.click()
     pyautogui.press("b")
     attack = pyautogui.locateOnScreen("attack.png",confidence=0.7)
     pyautogui.moveto(attack)
     pyautogui.click()
     pyautogui.press("f1")
     end = pyautogui.locateOnScreen(win)
     if (end == True):
      pyautogui.press("enter")
     break 

解决方法

问题在于 pyautogui.locateOnScreen() 不返回 True/False

pyautogui.locateOnScreen() 返回该图像的坐标，如果未找到该图像，则返回 None。

因此，您必须将 if (end == True): 更改为 if (end != None):。

将您的最终代码保留如下：

# Combat
nike = None
tour = "tour.png"
win = "win.png"
sort = "sort.png"
end = pyautogui.locateOnScreen(win)

while (nike == None):
    try:
     nike = pyautogui.locateOnScreen(tour)
     pyautogui.press("b")
     attack = pyautogui.locateOnScreen("attack.png",confidence=0.7)
     pyautogui.moveTo(attack)
     pyautogui.click()
     pyautogui.press("b")
     attack = pyautogui.locateOnScreen("attack.png",confidence=0.7)
     pyautogui.moveTo(attack)
     pyautogui.click()
     pyautogui.press("f1")
     end = pyautogui.locateOnScreen(win)
     if (end != None):
      pyautogui.press("enter")
     break 

此外，在 Python 中，您不需要在 if 和 while 语句中使用括号。因此您可以将 if (end != None): 更改为 if end != None:
