最后一次鼠标滚轮运动的心理记录时间

我需要记录上次为每次试验移动滚轮的时间。我有用于按键操作的代码(lastTrialTime变量):

 lastTime = 0 # setting up to get RT at last key press
    while timer.getTime() >0: # while time isn't up (turns neg when time's up)
        for key in event.getKeys():
            if key in ['escape']:
                core.quit() # quit if they press escape
            if key in ['b']:
            # add keypress to list for each keypress. then move cursor proportionally to length of this list
                b_list.append(key)
                prevPos+=len(b_list)
                lastTime = clock.getTime()
            if key in ['t']:
                t_list.append(key)
                prevPos-=len(t_list)
                lastTime = clock.getTime()
        lastTrialTime = lastTime

但我不确定如何对鼠标做出反应。我使用以下代码行来获取每次刷新时滚轮的移动量。

wheel_dX, wheel_dY = myMouse.getWheelRel()*4

但是,我无法弄清楚如何使用它(或其他东西?)来制作一个包含clock.getTime()调用的变量,用于最后一次滚轮移动。

答案 0 :(得分:2)

您可以测试值是否为0:

wheel_dX, wheel_dY = myMouse.getWheelRel()*4
if any([wheel_dX, wheel_dY]):
    lastTime = clock.getTime()
