    I am developing a Python script to pass a challenging minigame in a single-player title. My goal is to unlock a specific achievement within this game, a task I've spent over 10 hours attempting without success. This is also an opportunity for me to learn coding for the first time. So I thought, why not?

    This is the script

    from pyautogui import *
    import pyautogui
    import time
    import keyboard
    import random
    import win32api, win32con

    def press_spacebar():
    win32api.keybd_event(0x20, 0, 0, 0)
    time.sleep(0.05)
    win32api.keybd_event(0x20, 0, win32con.KEYEVENTF_KEYUP, 0)
    time.sleep(0.01)

    while keyboard.is_pressed('q')==False:

    if pyautogui.pixel(2400,690)[0] >= 150:
    press_spacebar()
    if pyautogui.pixel(2400,761)[0] >= 150:
    press_spacebar()


    And this is the minigame I was talking about. minigame

    The game requires precise timing: a fast-moving red bar oscillates vertically, and I need to stop it within a green zone by pressing spacebar (or mouse click). My approach is to use pixel scanning at the upper and lower boundaries of the green zone. When the red bar reaches these scanned points, the script triggers the spacebar press. My initial method of approaching this problem was to use pyautogui.press("space"), but it failed to nail the reaction time challenge. Every single time, its off by 200 to 250 mili sec, tried searching the internet for a better solution. This time I came across a win32api tutorial for piano tiles, claiming it is a lot faster than most common method. I tried using it in the script as shown above, still off about 150 mili sec. Now my problem is to reduce the latency to about under 100 mili sec if possible.
