pyautogui 像素颜色扫描器，手动有效但自动化无效

Question

我正在尝试创建一个简单的像素扫描器，方法是把鼠标从一个位置向下移动，直到碰到特定的颜色。我可以手动做到这一点，而且效果很好，但一旦我尝试自动化这个过程，它就失败了。

Python版本

Python 3.11.5

import pyautogui

while True:
  try:
    # Start positon of the mouse              <---- Automation
    pyautogui.moveTo(899,50)

    # Gets the positon
    position = pyautogui.position()

    # Gets the color of pixel
    color_matching = pyautogui.pixel(position.x,position.y)

    # Prints the pixel in format (255,255,255)
    print(color_matching)

    # - Green -
    #If the color matches prints "Found Green!"
    if color_matching == (86,183,39):
      print("Found Green!")
      break

    # - Red -
    #If the color matches prints "Found Red!"
    if color_matching == (244,59,13):
      print("Found Red!")
      break

    # End positon of the mouse              <---- Automation
    pyautogui.moveTo(899,1000,5)

  except:
    break

在没有自动化的情况下，我可以通过把鼠标移动到我选择的颜色上来让它工作。

但是在自动化的情况下，它只会在移动到这段代码时捕捉到第一个像素：

pyautogui.moveTo(899,50)

如果没有自动化，我只要在颜色匹配的地方加一个打印，它就会不断更新，但有了自动化后……正如之前提到的，它只会打印一次。

那么，我该怎么才能让它正常工作呢？我也希望它能运行得快一点，但首先我只想让它能正常工作。

我觉得你可以通过使用线程来解决这个问题。下面是代码：

import pyautogui
import threading

# Variable to control the scanning state
scanning = False

def startScan():
    global scanning
    scanning = True
    pyautogui.moveTo(899, 1000, 5)  # Move the mouse to a specific position
    scanning = False

while True:
    try:
        if not scanning:  # If scanning is completed, start again
            pyautogui.moveTo(899, 50)  # Start position of the mouse (Automation)
            
            # Start a new thread for moving the mouse
            threading.Thread(target=startScan, daemon=True).start()
    
        # Get the mouse position
        position = pyautogui.position()
    
        # Get the color of the pixel
        color_matching = pyautogui.pixel(position.x, position.y)
    
        # Print the pixel color in the format (255, 255, 255)
        print(color_matching)
    
        # Green
        # If the color matches, print "Found Green!" and exit the loop
        if color_matching == (86, 183, 39):
            print("Found Green!")
            break
    
        # Red
        # If the color matches, print "Found Red!" and exit the loop
        elif color_matching == (244, 59, 13):
            print("Found Red!")
            break
        
    except:
        break
