最近在做項目的時候，需要對界面進行不斷的刷新操作，在一定的時間內連續觸發某個函數，按照之前Python里的思路，第一反應是用time函數，但實際的效果并不好，經常會卡住，后來嘗試用pyqt5里自帶的計時器，這個問題完美解決。
做完項目順邊開了開腦洞，既然可以即時刷新，那么自然可以利用這一點設計個小游戲，比如打地鼠，廢話不多說，先上效果！

**（文末有素材和完整代碼）**碼字不易，喜歡請三聯！

不著急動手做，先來聊聊原理性的知識!
一、關于Timer計時器
PyQt5中自帶的timer計時器，是一種固定間隔刷新的計時器，可設置其刷新的間隔，也就是說我們可以以固定的間隔去觸發某個函數等等。
1.計時器的引入。

from PyQt5 import QtCore

2.相關的方法
QtCore.QTimer()：生成計時器
start()：啟動計時器，（）內設置時間，單位ms，也就是說start(1000)=1秒
timeout()：計時器啟動后，發射信號
stop():停止信號

二、計時器測試
1.我們先用QTdesiger做一個簡單的UI界面，如下：

測試代碼如下

from PyQt5 import QtCore, QtGui, QtWidgets from untitled01 import Ui_MainWindow import sysclass window(QtWidgets.QMainWindow, Ui_MainWindow):def __init__(self):super().__init__()self.setupUi(self)self.timer01 = QtCore.QTimer(self) #生成計時器self.timer01.start(1000) #設置間隔刷新間隔為1秒self.timer01.timeout.connect(self.test1) #每次觸發調用test1self.nn=1 #全局變量，用于停止def test1(self):self.nn+=1 #每次調用增加1print(self.nn) if self.nn==5: self.timer01.stop() #調用5次后停止print('已經停止')if __name__ == '__main__':app = QtWidgets.QApplication(sys.argv)MainWindow = window() # 創建窗體對象MainWindow.show() # 顯示窗體sys.exit(app.exec_()) # 程序關閉時退出進程

具體的測試細節在代碼注釋中，需要注意的是，第二行引用的untitled01，是UI文件生成的py文件，至于為什么這么引用，是因為不用擔心修改UI重新生成py文件后，不用擔心覆蓋源代碼，具體的操作模板，可以參考下面的文章【Python心得】解決PyQt5 UI更新同步問題，測試效果如下：

三、開始開腦洞
既然每次刷新都可以觸發函數，那么就可以在刷新之后隨機設置不同的背景，隨機生成不同的地鼠。具體制作思路如下：
1.設計UI,效果如下：

看起來很復雜？其實很簡單，素材我會放在文末，具體的制作也只要學會一步設置背景就可以了，具體參照下面的文章
【PyQt5】教你一招，分分鐘擼一個網易云音樂的UI界面，分分鐘學會！

2.計時器開始刷新時，生成一個隨機數列，包括9個數字，每個數字是0或者1，這里用1表示出現地鼠，用0表示沒有地鼠，所以只要判斷數列的每個數字是0或者1，然后設置不同的背景即可，比如數列的第一個數字如果是1，那么就在第一個坑設置有地鼠。具體代碼如下：

def Whac_a_mole(self):hole=[]for i in range(9):hole.append(str(random.randint(0,1))) #生成隨機數列if hole[0]=='1':self.pushButton_1.setStyleSheet('border-image: url(:/PNG/m01.png);')#設置有地鼠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.設置開始觸發代碼，具體如下：```pythondef start(self):self.time01.start(2000)# self.time01.timeout.connect(self.color_test)self.time01.timeout.connect(self.Whac_a_mole) `` 這里我把開始的代碼放到函數中，是希望能夠用開始按鈕去點擊觸發4.敲擊代碼。如果點擊對應的按鈕，就會進行判斷，如果是出現地鼠，則加載敲暈的圖片，否則沒有變化，這里用到的判斷，如何解決？ 我的思路是，上面的第二步代碼我們在隨機生成的列表中，加載圖片的同時，可以順便用settext()將0或者1，設置到按鈕中，如果感覺設置的數字會影響按鈕美觀，可以將字號設置成1，幾乎看不出來的。 敲擊代碼如下：```pythondef hit01(self):if self.pushButton_1.text()=='1':self.pushButton_1.setStyleSheet('border-image: url(:/PNG/m02.png);')

需要對每個按鈕都進行設置，這里不全部列出來了！

上面第二步需要增加的代碼如下：

#設置標志位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，設置停止按鈕，這步一行就可以，但。。。輕微強迫癥讓我必須回到初始狀態，所以代碼如下：

#停止按鈕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);')

寫到這基本思路就完成了。效果如下：
