python - 无论鼠标单击如何，psychopy 鼠标跟踪都会返回 true

Question

我正在尝试 psychopy 的鼠标跟踪功能。对于初学者，我只想记录是否发生鼠标单击。即使我不点击鼠标，它也会打印“被按下”。我正在使用 v1.84.2。

from psychopy import core, visual, gui, data, misc, event, sound
import time, random, math, os
import numpy as np
import copy
from pygame import mouse, locals, display

screenSize =[1280, 800]
win = visual.Window(size = screenSize, fullscr = True, allowGUI=False, monitor='testMonitor', units='deg')

mouse = event.Mouse(visible=True, newPos=[0,0])

mouse.clickReset()

if mouse.getPressed():
    print ("got pressed")

Answer 1

mouse.getPressed() 返回一个包含 3 个元素的元组，表示按下的鼠标按钮，因此 (1, 0, 0) 表示左键被按下按下 s 你的代码应该是这样的:

from psychopy import core, visual, gui, data, misc, event, sound
import time, random, math, os
import numpy as np
import copy
from pygame import mouse, locals, display

screenSize =[1280, 800]
win = visual.Window(size = screenSize, fullscr = True, allowGUI=False, monitor='testMonitor', units='deg')

mouse = event.Mouse(visible=True, newPos=[0,0])

mouse.clickReset()

if mouse.getPressed()[0]:
    print ("got pressed")
