在鼠标按下时运行循环

如何解决在鼠标按下时运行循环

我有这个代码：

import pyautogui
from pynput.mouse import Listener
# import threading
import time

mouseIsDown = False

def on_click(*args):
    if args[-1]:
        if args[-2].name == "left":
            mouseIsDown = True
            print("down")

    elif not args[-1]:
        if args[-2].name == "left":
            mouseIsDown = False
            print("up")

with Listener(on_click=on_click) as listener:
    listener.join()

while mouseIsDown:
    print("hello!")
    time.sleep(0.001)

它应该在按下鼠标按钮时每 0.001 秒运行一次循环，但它什么也没做。

有什么建议吗？

解决方法

以非阻塞方式运行这个线程，你可能需要这样的东西(Read it in document)：

import pyautogui
from pynput.mouse import Listener
# import threading
import time

mouseIsDown = False

def on_click(*args):
    global mouseIsDown
    if args[-1]:
        if args[-2].name == "left":
            mouseIsDown = True
            print("down")

    elif not args[-1]:
        if args[-2].name == "left":
            mouseIsDown = False
            print("up")

listner = Listener(on_click=on_click)
listner.start()

while True:
    if mouseIsDown:
        time.sleep(0.5) # time to sleep
        print("hello!")
