【PyQt5】教你一招，用timer计时器做个打地鼠的小游戏

最近在做项目的时候，需要对界面进行不断的刷新操作，在一定的时间内连续触发某个函数，按照之前Python里的思路，第一反应是用time函数，但实际的效果并不好，经常会卡住，后来尝试用pyqt5里自带的计时器，这个问题完美解决。
做完项目顺边开了开脑洞，既然可以即时刷新，那么自然可以利用这一点设计个小游戏，比如打地鼠，废话不多说，先上效果！

**（文末有素材和完整代码）**码字不易，喜欢请三联！

不着急动手做，先来聊聊原理性的知识!
一、关于Timer计时器
PyQt5中自带的timer计时器，是一种固定间隔刷新的计时器，可设置其刷新的间隔，也就是说我们可以以固定的间隔去触发某个函数等等。
1.计时器的引入。

from PyQt5 import QtCore

2.相关的方法
QtCore.QTimer()：生成计时器
start()：启动计时器，（）内设置时间，单位ms，也就是说start(1000)=1秒
timeout()：计时器启动后，发射信号
stop():停止信号

二、计时器测试
1.我们先用QTdesiger做一个简单的UI界面，如下：

测试代码如下

from PyQt5 import QtCore, QtGui, QtWidgets
from untitled01 import Ui_MainWindow
import sys

class window(QtWidgets.QMainWindow, Ui_MainWindow):
    def __init__(self):
        super().__init__()
        self.setupUi(self)
        self.timer01 = QtCore.QTimer(self) #生成计时器
        self.timer01.start(1000) #设置间隔刷新间隔为1秒
        self.timer01.timeout.connect(self.test1) #每次触发调用test1
        self.nn=1 #全局变量，用于停止

    def test1(self):
        self.nn+=1 #每次调用增加1
        print(self.nn) 
        if self.nn==5: 
            self.timer01.stop() #调用5次后停止
            print('已经停止')

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = window()  # 创建窗体对象
    MainWindow.show()  # 显示窗体
    sys.exit(app.exec_())  # 程序关闭时退出进程

具体的测试细节在代码注释中，需要注意的是，第二行引用的untitled01，是UI文件生成的py文件，至于为什么这么引用，是因为不用担心修改UI重新生成py文件后，不用担心覆盖源代码，具体的操作模板，可以参考下面的文章【Python心得】解决PyQt5 UI更新同步问题，测试效果如下：

三、开始开脑洞
既然每次刷新都可以触发函数，那么就可以在刷新之后随机设置不同的背景，随机生成不同的地鼠。具体制作思路如下：
1.设计UI,效果如下：

看起来很复杂？其实很简单，素材我会放在文末，具体的制作也只要学会一步设置背景就可以了，具体参照下面的文章
【PyQt5】教你一招，分分钟撸一个网易云音乐的UI界面，分分钟学会！

2.计时器开始刷新时，生成一个随机数列，包括9个数字，每个数字是0或者1，这里用1表示出现地鼠，用0表示没有地鼠，所以只要判断数列的每个数字是0或者1，然后设置不同的背景即可，比如数列的第一个数字如果是1，那么就在第一个坑设置有地鼠。具体代码如下：

    def Whac_a_mole(self):
        hole=[]
        for i in range(9):
            hole.append(str(random.randint(0,1))) #生成随机数列
        if hole[0]=='1':
            self.pushButton_1.setStyleSheet('border-image: url(:/PNG/m01.png);')#设置有地鼠
        else:
            self.pushButton_1.setStyleSheet('border-image: url(:/PNG/k01.png);')
        if hole[1]=='1':
            self.pushButton_2.setStyleSheet('border-image: url(:/PNG/m01.png);')
        else:
            self.pushButton_2.setStyleSheet('border-image: url(:/PNG/k01.png);')
        if hole[2]=='1':
            self.pushButton_3.setStyleSheet('border-image: url(:/PNG/m01.png);')
        else:
            self.pushButton_3.setStyleSheet('border-image: url(:/PNG/k01.png);')
        if hole[3]=='1':
            self.pushButton_4.setStyleSheet('border-image: url(:/PNG/m01.png);')
        else:
            self.pushButton_4.setStyleSheet('border-image: url(:/PNG/k01.png);')
        if hole[4]=='1':
            self.pushButton_5.setStyleSheet('border-image: url(:/PNG/m01.png);')
        else:
            self.pushButton_5.setStyleSheet('border-image: url(:/PNG/k01.png);')
        if hole[5]=='1':
            self.pushButton_6.setStyleSheet('border-image: url(:/PNG/m01.png);')
        else:
            self.pushButton_6.setStyleSheet('border-image: url(:/PNG/k01.png);')
        if hole[6]=='1':
            self.pushButton_7.setStyleSheet('border-image: url(:/PNG/m01.png);')
        else:
            self.pushButton_7.setStyleSheet('border-image: url(:/PNG/k01.png);')
        if hole[7]=='1':
            self.pushButton_8.setStyleSheet('border-image: url(:/PNG/m01.png);')
        else:
            self.pushButton_8.setStyleSheet('border-image: url(:/PNG/k01.png);')
        if hole[8]=='1':
            self.pushButton_9.setStyleSheet('border-image: url(:/PNG/m01.png);')
        else:
            self.pushButton_9.setStyleSheet('border-image: url(:/PNG/k01.png);')```

3.设置开始触发代码，具体如下：

```python
    def start(self):
        self.time01.start(2000)
        # self.time01.timeout.connect(self.color_test)
        self.time01.timeout.connect(self.Whac_a_mole)
``
这里我把开始的代码放到函数中，是希望能够用开始按钮去点击触发

4.敲击代码。如果点击对应的按钮，就会进行判断，如果是出现地鼠，则加载敲晕的图片，否则没有变化，这里用到的判断，如何解决？
我的思路是，上面的第二步代码我们在随机生成的列表中，加载图片的同时，可以顺便用settext()将0或者1，设置到按钮中，如果感觉设置的数字会影响按钮美观，可以将字号设置成1，几乎看不出来的。
敲击代码如下：

```python
    def hit01(self):
        if self.pushButton_1.text()=='1':
            self.pushButton_1.setStyleSheet('border-image: url(:/PNG/m02.png);')

需要对每个按钮都进行设置，这里不全部列出来了！

上面第二步需要增加的代码如下：

      #设置标志位
        self.pushButton_1.setText(hole[0])
        self.pushButton_2.setText(hole[1])
        self.pushButton_3.setText(hole[2])
        self.pushButton_4.setText(hole[3])
        self.pushButton_5.setText(hole[4])
        self.pushButton_6.setText(hole[5])
        self.pushButton_7.setText(hole[6])
        self.pushButton_8.setText(hole[7])
        self.pushButton_9.setText(hole[8])

5.最后一步，设置停止按钮，这步一行就可以，但。。。轻微强迫症让我必须回到初始状态，所以代码如下：

    #停止按钮
    def stop(self):
        self.time01.stop()
        self.pushButton_1.setStyleSheet('border-image: url(:/PNG/k01.png);')
        self.pushButton_2.setStyleSheet('border-image: url(:/PNG/k01.png);')
        self.pushButton_3.setStyleSheet('border-image: url(:/PNG/k01.png);')
        self.pushButton_4.setStyleSheet('border-image: url(:/PNG/k01.png);')
        self.pushButton_5.setStyleSheet('border-image: url(:/PNG/k01.png);')
        self.pushButton_6.setStyleSheet('border-image: url(:/PNG/k01.png);')
        self.pushButton_7.setStyleSheet('border-image: url(:/PNG/k01.png);')
        self.pushButton_8.setStyleSheet('border-image: url(:/PNG/k01.png);')
        self.pushButton_9.setStyleSheet('border-image: url(:/PNG/k01.png);')

写到这基本思路就完成了。效果如下：
