Question

我正在尝试用kivy做一个基本的隐藏对象游戏，但是因为我是一个新手，所以有点难。所以我所做的是使用flowLayout的画布我已经显示了4张图像，现在我希望它们在我点击 ON THEM 后消失。我应该怎么做以及实现这个目标的最佳方法是什么？

另外，我想要一个标签来显示倒计时。我放了一个标签，但它不起作用。所以我暂时只是评论它。如果有人可以解释我哪里出错了。

Config.set('graphics', 'width', '480')

running= True


class MyWidget(AnchorLayout):
    time_number = StringProperty()

    def __init__(self, **kwargs):
        super(MyWidget, self).__init__(**kwargs)
        self.time_number = str(50)
    def call(self):
        if running:
            #print(self.time_number)
            #self.time_number = str(int(self.time_number)+1)
            pass            
    def clicked(self):
        global running
        #self.time_number = 50
        running=False

    Clock.schedule_interval(call, 1)

    pos1 =(0) #random.randint(-200,200)
    pos2 =(0) #random.randint(-200,200)

对于每个矩形，将on_press属性设置为从其父窗口小部件中删除矩形窗口小部件的函数。如：

<MyWidget>:
    grid_layout: grid_layout
    AnchorLayout:
        BoxLayout:
            Image:
                source:'B_image.png'
        BoxLayout:
            Label:
                text:root.time_number
        GridLayout:
            rows: 2
            id: grid_layout
            Button:
                background_normal: 'image.png'
                on_press: root.remove_rectangle(widget=self)
            Button:
                background_normal: 'image.png'
                on_press: root.remove_rectangle(widget=self)
            Button:
                background_normal: 'image.png'
                on_press: root.remove_rectangle(widget=self)
            Button:
                background_normal: 'image.png'
                on_press: root.remove_rectangle(widget=self)

在main.py中：

class MyWidget(AnchorLayout):
    ...
    def remove_rectangle(self, widget):
        self.grid_layout.remove_widget(widget)
