This paper describes how to write game assistant scripts in Python

The main way to achieve this is to click on the line in the game by comparing pictures.Running a program requires the following.

PIL: Picture Processing Module (python3 replaced with pillow) Download address: https://www.lfd.uci.edu/~gohlke/pythonlibs/

pywin32: pip install pypiwin32 to simulate clicks

tesseract: Implement picture and text recognition. Here is the installation tutorial. https://blog.csdn.net/dcrmg/article/details/78233459?locationNum=7&fps=1

#Get the window handle on your computer
def foo(hwnd,mouse):
    if IsWindow(hwnd) and IsWindowEnabled(hwnd) and IsWindowVisible(hwnd):
        titles.add(GetWindowText(hwnd))

# This code finds the simulator and opens the game interface at the specified location according to the coordinates set
def playGame():
    """Click the game icon in the simulator to enter and displays to the specified location"""
    EnumWindows(foo, 0)
    list = []
    for title in titles:
        if title:
           list.append(title)
    for title in list:
        a = 'Night God simulator'
        if title.find(a) != -1:
            hwnd = win32gui.FindWindow(0,a)
            win32gui.SetWindowPos(hwnd, win32con.HWND_TOP, 0, 0, 640, 360, win32con.SWP_SHOWWINDOW)
            hwnd = win32gui.FindWindow(0,a)
            size = win32gui.GetWindowRect(hwnd)
            # Click on the game icon in the emulator to enter the game
            win32api.SetCursorPos([size[0] + 410, size[1] + 186])
            win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP | win32con.MOUSEEVENTF_LEFTDOWN, 0, 0)
            win32api.mouse_event(win32con.MOUSEEVENTF_RIGHTUP | win32con.MOUSEEVENTF_RIGHTDOWN, 0, 0)
            time.sleep(10)
            return size

def game():
    """Click to implement in the game"""

    # Click I Know
    size = playGame()
    time.sleep(15)
    topx, topy = size[0], size[1]
    ImageGrab.grab((topx + 287, topy + 307, topx + 350, topy + 330)).save('D:\ ceshi.jpg') # Capture pictures in a game based on a given size
    # Comparing the Recognition of Two Pictures Using the Picture hash Algorithm
    hash_size = 6
    hash1 = imagehash.average_hash(Image.open('D:\ ceshi.jpg'), hash_size=hash_size)
    hash2 = imagehash.average_hash(Image.open('D:\I got it!.jpg'), hash_size=hash_size)
    a = (1 - (hash1 - hash2) / len(hash1.hash) ** 2)
    print(a)
    if a > 0.6:
        # Operate mouse clicks
        win32api.SetCursorPos([topx + 290, topy + 310])
        win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP | win32con.MOUSEEVENTF_LEFTDOWN, 0, 0)
        win32api.mouse_event(win32con.MOUSEEVENTF_RIGHTUP | win32con.MOUSEEVENTF_RIGHTDOWN, 0, 0)

For the image hashing algorithm above, https://blog.csdn.net/sinat_26917383/article/details/78582064?LocionNum=8&fps=1 is a relatively inexact algorithm, which will be matched based on the text on the recognized picture.
