Python / pygame按钮功能

Question

我正在创建一个基于测验的游戏，我目前有一个名为Quiz.py的主菜单形式，如下代码所示，这只是在构建我的主菜单。 然后将其导入另一个名为Maths.py的文件，这是我将要构建的3个测试之一。

我的问题是，如何对我的Maths.py文件中的按钮进行编码，以便用户单击数学按钮时，它们会启动一个随机生成的数学问题循环。

这是我的测验文件中的代码

import random
import time # these are importing everything I will need for my program. 
import pygame
pygame.init() # Initiates pygame so it runs.
display_width = 1600 # This sets the boundries of the pygame screen
display_height = 800
gamedisplay = pygame.display.set_mode((display_width,display_height))
white = (255,255,255)
black = (000,000,000)
grey = (169,169,169)
clock = pygame.time.Clock()
buttonheight = 100
buttonwidth = 250
class Button:
    x=0
    y=0
    height=100
    width=250

    body = None
    text="Maths"

    def __init__(self):
        self.body = pygame.Rect(self.x, self.y, self.width, self.height)

    def setText(self, textOfButton):
        self.text = textOfButton

    def clicked(self):
        print("test")

    def checkClicked(self):
        click = pygame.mouse.get_pressed()
        x, y = 0,1
        click = 0
        if pygame.mouse.get_pos()[x] > self.x and pygame.mouse.get_pos()[x] < self.x + self.width:
            if pygame.mouse.get_pos()[y] > self.y and pygame.mouse.get_pos()[y] < self.y + self.height:
                self.clicked()

    def draw(self):
        smallText = pygame.font.Font ('RINGM___.ttf',20, )
        TextSurf, TextRect = text_objectsW(self.text,smallText)
        TextRect.center = ( (self.x+(self.width/2)), (self.y+(self.height/2)))

        pygame.draw.rect(gamedisplay, black, self.body)
        gamedisplay.blit(TextSurf, TextRect)

        #gamedisplay.blit(smallText.render(self.text, False, white), TextRect)


class mathsButton(Button):
    def __init__(self):
        self.x = 95
        self.y = 400
        self.text = "Maths"
        super().__init__()

class historyButton(Button):
    def __init__(self):
        self.x=690
        self.y=400
        self.text = "History"
        super().__init__()


class englishButton (Button):
    def __init__(self):  
        self.x=1255
        self.y=400
        self.text="English"
        super().__init__()

def text_objectsB (text, font): # These 2 functions are the same with the colour of the text being the exception.  its renders the text and its colour
    textSurface = font.render(text, True, black)
    return textSurface, textSurface.get_rect()
def text_objectsW (text, font):
    textSurface = font.render(text, True, white)
    return textSurface, textSurface.get_rect()

my_image = pygame.image.load('Background2.jpg').convert()
gamedisplay.blit(my_image, [0,0])
intro = True
btnMaths = mathsButton()
btnHistory = historyButton()
btnEnglish = englishButton()

def main_menu():
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()
            elif event.type == pygame.MOUSEBUTTONDOWN:
                btnMaths.checkClicked()
                btnHistory.checkClicked()
                btnEnglish.checkClicked()
        largetext = pygame.font.Font('RINGM___.ttf',80)
        TextSurf, TextRect = text_objectsB("Are you smarter than a 13 year old?", largetext)
        TextRect.center = ((display_width/2),(display_height/6))
        gamedisplay.blit(TextSurf, TextRect)
        #button("Maths Quiz",95,400,black,grey,"Maths")
        #button("English Quiz",675,400,black,grey,"English")
        #button("History Quiz",1255,400,black,grey,"History")
        btnMaths.draw()
        btnHistory.draw()
        btnEnglish.draw()
        pygame.display.update()
        clock.tick(60)

这是我的Maths文件的代码

import pygame
import random, time
import Quiz 
t0 = time.time()
while True:
    Quiz.main_menu()
    if time.time() - t0 > 5:
        Quiz.btnMaths.setText("New Text") # This code is proof on concept that i can change the text in this box

感谢您的任何帮助，您可以提供。

我会说在checkClicked函数中返回一个布尔值。

def checkClicked(self):
    click = pygame.mouse.get_pressed()
    x, y = 0,1
    click = 0
    if pygame.mouse.get_pos()[x] > self.x and pygame.mouse.get_pos()[x] < self.x + self.width:
        if pygame.mouse.get_pos()[y] > self.y and pygame.mouse.get_pos()[y] < self.y + self.height:
            return True
        else:
            return False

然后是程序循环中的if语句

if checkClicked() == True:
