Question

我正在尝试玩游戏时获得输入（确切地说是《魔兽争霸III》）。由于它是RTS游戏，因此在短时间内需要大量输入。我正在尝试使用pyWinhook来获取输入，使用mss来获取屏幕截图，并使用cv进行图像处理。

我试图在获取输入后立即禁用图像处理，以减少脚本的工作量。尽管如此，它并没有太大的区别。我还尝试减少游戏中的图形细节-也没有区别。

我怀疑线程会由于大量输入而节流，而不是使用的硬件不是很好（我在具有4GB RAM的Lenovo X240上工作）。

import os

import cv2
import mss
import numpy as np
import pyWinhook as pyHook
import pythoncom


def main():
    # file names for training data arrays
    file_name = 'training_data.npy'
    copy_file_name = 'training_data_copy.npy'

    # deciding if previous file with data is saved. If yes, it is opened. If not it's created
    if os.path.isfile(file_name):
        print('File exists, loading previous data!')
        print(os.path.realpath(file_name))
        training_data = list(np.load(file_name, allow_pickle=True))
        np.save(copy_file_name, training_data)
    else:
        print('File does not exist, starting fresh!')
        training_data = []

    # getting screenshot and processing it for optimal machine learning processing
    def get_screen():
        with mss.mss() as sct:
            screen = np.array(sct.grab((0, 0, 1366, 768)))
        screen = cv2.cvtColor(screen, cv2.COLOR_BGR2GRAY)
        screen = cv2.resize(screen, (136, 76))
        return screen

    # saving data after acquiring 2500 sets of inputs and screenshots
    def save_data(screen, output):
        training_data.append([screen, output])
        if len(training_data) % 2500 == 0:
            print(len(training_data))
            np.save(file_name, training_data)
        print("Frames taken: " + str(len(training_data)))

    # getting inputs and screen on mouse event
    def OnMouseEvent(event):
        screen = get_screen()
        action = [event.Position, event.Wheel]
        output = action
        save_data(screen, output)
        return True

    # getting inputs and screen on keyboard event
    def OnKeyboardEvent(event):
        screen = get_screen()
        output = event.Key
        save_data(screen, output)
        return True

    # create a hook manager
    hm = pyHook.HookManager()

    # watch for all mouse events
    hm.MouseAll = OnMouseEvent
    hm.KeyUp = OnKeyboardEvent

    # set the hook
    hm.HookMouse()
    hm.HookKeyboard()

    # wait forever
    try:
        pythoncom.PumpMessages()
    except KeyboardInterrupt:
        pass

    # looping getting data
    while True:
        pass


if __name__ == '__main__':
    main()

我想尽可能地优化获取输入，因为目前游戏中的输入是滞后的（不适当，因为最佳输入是机器学习模块的基础）。

我完全意识到，由于硬件速度慢和每分钟的输入量过大，这可能是一个无法解决的问题，但无论如何我还是想尝试。

pyHook钩子使输入太滞后-是否有优化这些钩子的方法？
