我编写此代码是为了在 GTA 5 中驾驶汽车。但是键盘仅模拟 Pycharm 中的击键，而不是其他应用程序

Question

from pyautogui import press, typewrite, hotkey
import cv2 as cv
import mediapipe as mp
from mediapipe.tasks import python
from mediapipe.tasks.python import vision
from pynput.keyboard import Key, Controller
keyboard = Controller()
model_path = r'C:\Users\Saransh\PycharmProjects\OpenCV\gesture_recognizer.task'                                         
BaseOptions = mp.tasks.BaseOptions                                                                                      
GestureRecognizer = mp.tasks.vision.GestureRecognizer
GestureRecognizerOptions = mp.tasks.vision.GestureRecognizerOptions
GestureRecognizerResult = mp.tasks.vision.GestureRecognizerResult
VisionRunningMode = mp.tasks.vision.RunningMode
def print_result(result: GestureRecognizerResult,output_image: mp.Image,timestamp_ms: int):
    if(type(result.gestures)==list and result.gestures):
        if(result.gestures[0][0].category_name=='Pointing_Up'):
            press('w')
        if(result.gestures[0][0].category_name=='Victory'):
            press('d')
        if(result.gestures[0][0].category_name=='ILoveYou'):
            press('a')
        if(result.gestures[0][0].category_name=='Closed_Fist'):
            press('s')
    if(type(result.gestures)==list and result.gestures):
        print(result.gestures[0][0].category_name)
options = GestureRecognizerOptions(                                                                                     
    base_options=     BaseOptions(model_asset_path="C:\\Users\\Saransh\\PycharmProjects\\OpenCV\\gesture_recognizer.task"),
    running_mode =VisionRunningMode.LIVE_STREAM,                
    result_callback=print_result)                               
cap= cv.VideoCapture(0)
frame_timestamp_ms = 0
with GestureRecognizer.create_from_options(options) as recognizer:
        while cap.read():
            res,frame=cap.read()
            if(res==False):
                break
            frame=cv.flip(frame,1)
            frame=cv.cvtColor(frame, cv.COLOR_BGR2RGB)
            k=cv.waitKey(1)
            mp_image=mp.Image(image_format=mp.ImageFormat.SRGB,data=frame)
            recognizer.recognize_async(mp_image,frame_timestamp_ms)
            frame_timestamp_ms+=1
        cap.release()
        cap.destroyAllWindows()

我希望按键也能在其他应用程序中复制，但它只在 pycharm 环境中复制。任何人都可以帮我吗？它只在 Pycharm 和其他一些应用程序（如 Brave 浏览器、spotif、记事本）中复制，但在其他应用程序中不复制

Answer 1

在这种情况下，最好使用其中一个

pywin32

模块，来帮助你一点，因为似乎仅仅模拟按键是不够的，你需要将其直接发送到应用程序：

import win32com.client, time
shell = win32com.client.Dispatch("WScript.Shell")
shell.Run('name of the app you are trying to run')
time.sleep(3)
shell.AppActivate('same name as earlier')
shell.SendKeys('s') #sends key s to the application

感谢 this stackoverflow 帖子提供了大部分代码:)

在任何情况下，

pyautogui

、

keyboard

和

pynput

有时无法访问应用程序，特别是如果应用程序处于非活动状态（我假设在您的情况下它是活动的）。
