Question

我有一些按钮连接到json文件中的键。使用kivy的Clock模块，我检查连接到按钮的值并更改其颜色。当按钮变成红色时，我希望它的score值变成0并存储在json文件中。当我将多个按钮保存在json文件中时，直到我按下其中一个按钮，分数才会变为零；当我按下按钮时，除第一个按钮之外的所有值都变为0，这不是我想要的。

class MainApp(App):
    def build(self):  # build() returns an instance
        self.store = JsonStore("streak.json")  # file that stores the streaks:
        Clock.schedule_interval(self.check_streak, 1 / 30.)

        return presentation

    def check_streak(self, dt):

        for child in reversed(self.root.screen_two.ids.streak_zone.children):
            name = child.text

            with open("streak.json", "r") as read_file:
                data = json.load(read_file)

            for key in data.keys():
                if key == name:
                    delay = data.get(key, {}).get('delay')  # get value of nested key 'delay'
                    self.honey = data[key]['delta']
                    float(self.honey)


                if delay > time.time() < self.honey:  # early (yellow)
                    child.background_normal = ''
                    child.background_color = [1, 1, 0, 1]
                    child.unbind(on_press=self.add_score)
                    child.bind(on_press=self.early_click)

                elif delay > time.time() > self.honey:  # on time (green)
                    child.background_normal = ''
                    child.background_color = [0, 1, 0, 1]
                    child.unbind(on_press=self.early_click)
                    child.bind(on_press=self.add_score)

                elif delay < time.time() > self.honey:  # late (red)
                    child.background_normal = ''
                    child.background_color = [1, 0, 0, 1]
                    child.unbind(on_press=self.add_score)
                    child.unbind(on_press=self.early_click)

                    with open("streak.json", "r+") as f:
                        files = json.load(f)
                        files[child.text]['score'] = 0
                        f.seek(0)
                        json.dump(files, f, indent=4)
                        f.truncate()

json文件：

{
    "One": {
        "action": "One",
        "delay": 1558740875.58999,
        "seconds": 60,
        "score": 3,
        "delta": 1558740815.58999,
        "grace_sec": 120
    },
    "Two": {
        "action": "Two",
        "delay": 1558740752.0085213,
        "seconds": 60,
        "score": 0,
        "delta": 1558740692.0085213,
        "grace_sec": 120
    },
    "Three": {
        "action": "Three",
        "delay": 1558746820.4364505,
        "seconds": 60,
        "score": 0,
        "delta": 1558740820.4364505,
        "grace_sec": 6060
    }
}

我只希望红色按钮将其score更改为0，但是Two和Three都更改，即使只有Two是红色的。另外，仅当我按下绿色按钮时分数才会改变，在本例中为One。这不是我想要的。我希望乐谱使用“时钟”模块更新其自我。

Answer 1

案例1：我认为time.time（）总是对延迟和蜜月都更大，并且每次进入第三条件并将得分设置为零。

另一个选项：只需跟踪列表中所有红色按钮，然后对其进行迭代并立即更新json文件。

Answer 2

创建了一个单独的函数，该函数使用时钟来更新json文件。

# change score to 0 and stores in json file
    def score_gone(self, dt):
        for child in self.root.screen_two.ids.streak_zone.children:
            name = child.text
            color = child.background_color

            with open("streak.json", "r") as file:
                read = json.load(file)

            if color == [1, 0, 0, .95]: # red

                if read[name]['score'] != 0: #stops slow down from Clock
                    with open("streak.json", "r+") as f: # fix score not reseting to 0
                            data = json.load(f)
                            data[name]['score'] = 0
                            f.seek(0)
                            json.dump(data, f, indent=4)
                            f.truncate()

                elif read[name]['score'] == 0: #stops slow down from Clock
                        pass

为什么我的json文件中存储的值没有更改？
