为什么这会抛出索引？

Question

免责声明：我不知道如果您要运行代码会发生什么，因为我已经对其进行了一些更改。

对于那些好奇的人来说，代码的作用都没关系：它可以使像素艺术绘画游戏自动化，其中正方形以数字为标志，您可以用相应的颜色单击它们。这并不是该代码的作用，但这并不重要。

错误：

from pyautogui import *
import pyautogui
import win32api, win32con

white = (198, 198, 196)
blue = (125, 149, 199)

x1, y1, width, height = 10, 20, 1029, 798

x2 = x1 + width
y2 = y1 + height

while True:
    s = pyautogui.screenshot(region=(x1, y1, width, height))
    for x in range(x1, x2):
        for y in range(y1, y2):
            if s.getpixel((x, y)) == blue:
                s = pyautogui.screenshot(region=(x1, y1, width, height))
                win32api.SetCursorPos((range(x1, x2), range(y1, y2)))

屏幕截图图像中的像素索引从 0 开始，而不是从 x1 和 y1 开始。所以你需要从你的索引中减去它们。

while True:
    s = pyautogui.screenshot(region=(x1, y1, width, height))
    for x in range(x1, x2):
        for y in range(y1, y2):
            curpixel = s.getpixel((x - x1, y - y1))
            if curpixel == blue:
                s = pyautogui.screenshot(region=(x1, y1, width, height))
                win32api.SetCursorPos((range(x1, x2), range(y1, y2)))
                win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN,0,0)
                time.sleep(0.01)
                win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP,0,0)
                s = pyautogui.screenshot(region=(x1, y1, width, height))
            if curpixel == white:
                s = pyautogui.screenshot(region=(x1, y1, width, height))
                win32api.SetCursorPos((range(x1, x2), range(y1, y2)))
                win32api.mouse_event(win32con.MOUSEEVENTF_RIGHTDOWN,0,0)
                time.sleep(0.01)
                win32api.mouse_event(win32con.MOUSEEVENTF_RIGHTUP,0,0)
                time.sleep(0.01)
                s = pyautogui.screenshot(region=(x1, y1, width, height))
            elif scurpixel != white and curpixel != blue:
                break
            else:
                continue
