python - 微型 :bit python Rock Paper Scissors debugging

Question

我是 Micro:bit python 的初学者。我正在为带有计分系统的“剪刀石头布”游戏编写代码。但是，它会响应一次摇动，然后即使没有人摇动它也会自动显示一张图片。您能建议一种解决此问题的方法吗？

from microbit import *
import random

count = 0

paper = Image("99999:"
            "90009:"
            "90009:"
            "90009:"
            "99999")
rock = Image("00000:"
            "09990:"
            "09990:"
            "09990:"
            "00000:")
scissors = Image("00099:"
                "99090:"
                "00900:"
                "99090:"
                "00099:")
while True:
    while True:
        if accelerometer.is_gesture("shake"):
            display.clear()
            choice = random.randint(0, 2)
            if choice == 0:
                display.show(rock)
                break
            elif choice == 1:
                display.show(paper)
                break
            else:
                display.show(scissors)
                break
    while True:
        if button_a.is_pressed():
            count = count + 1
            display.scroll(str(count))
            break
        elif button_b.is_pressed():
            count = count - 1
            display.scroll(str(count))
            break
        elif pin0.is_touched():
            display.scroll(str(count))
            break

Answer 1

根据我从文档中可以理解的内容， 尝试更改这行代码:if accelerometer.is_gesture("shake"): 到 if accelerometer.was_gesture("shake"):

他们的区别，来自文档:
对于 is_gesture:

Return True or False to indicate if the named gesture is currently active.

对于 was_gesture:

Return True or False to indicate if the named gesture was active since the last call.
