减少Pynput鼠标侦听器的资源消耗

如何解决减少Pynput鼠标侦听器的资源消耗

我正在尝试使用来自pynput的This脚本来监视鼠标，但是它过于占用资源。

尝试使用import time，并在time.sleep(1)函数之后添加on_move(x,y)，但是当您运行它时，鼠标会发疯。

这是整体代码：

import time

def on_move(x,y):
    print('Pointer moved to {0}'.format((x,y)))
    time.sleep(1) # <<< Tried to add it over here cuz it takes most of the process.

def on_click(x,y,button,pressed):
    print('{0} at {1}'.format('Pressed' if pressed else 'Released',(x,y)))
    if not pressed:
        return False

def on_scroll(x,dx,dy):
    print('Scrolled {0}'.format((x,y)))
with Listener(on_move=on_move,on_click=on_click,on_scroll=on_scroll) as listener:
    listener.join()

解决方法

执行某些将阻止代码的任务时，您可以使用线程来运行代码。（在您的代码中，sleep(1)将阻止代码），无论如何，这在我的PC上可以正常工作：

from pynput.mouse import Listener
import time
import threading

def task(): # this is what you want to do.
    time.sleep(1)  # <<< Tried to add it over here cuz it takes most of the process.
    print("After sleep 1 second")

def on_move(x,y):
    print('Pointer moved to {0}'.format((x,y)))
    threading.Thread(target=task).start() # run some tasks here.

def on_click(x,y,button,pressed):
    print('{0} at {1}'.format('Pressed' if pressed else 'Released',(x,y)))
    if not pressed:
        return False

def on_scroll(x,dx,dy):
    print('Scrolled {0}'.format((x,y)))


with Listener(on_move=on_move,on_click=on_click,on_scroll=on_scroll) as listener:
    listener.join()
