Python - 游戏没有响应？

Question

尝试创建一个新的游戏实例，以便我可以创建一个在实际游戏发生之前显示的主菜单。

我正在尝试这样当你按下键盘上的 a 时，游戏会开始并且主菜单会消失，但游戏会循环一些代码并使其崩溃；没有反应。

import pygame
import random
import time
pygame.init()

        self.vel = 5
        self.x_change = random.randrange(1,3)
        self.y_change = 1
        self.height = random.randrange(35, 60)
        self.width = random.randrange(60, 70)
        self.color = random.sample(range(250), 4)
        self.image = pygame.Surface([self.width, self.height], pygame.HWSURFACE, 32)
        self.rect = self.image.get_rect(topleft = (random.randrange(700, 1200), 550))
        self.image.fill(self.color)
        #pygame.draw.rect(self.image, (self.color), (self.x, self.y, self.width, self.height))

    def draw(self):

如果有人能找出是什么破坏了我的游戏，那就太棒了。

你在一个游戏循环里面有一个游戏循环。不不不。你有while mainMenu == True 然后在那个循环里面你有一个while mainMenu == False 所以当它是主菜单时它正在循环通过大循环，然后当它为假时，它循环通过小循环并且永远不会出去。

你可以有多个游戏循环，但不能互相使用

while mainMenu == True:
    window.blit(mainmenu, (0,0))
    pygame.display.flip()
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False   #if x is pressed dont run game
            mainMenu = False
    keys = pygame.key.get_pressed()
    if keys[pygame.K_a]:
        mainMenu = False  #if a is pressed run game
        print ("yeah i clicked")

while run:
    window.blit(bg, (0,0))
    window.blit(TextSurf, TextRect)
    window.blit(TextSurf2, TextRect2)
    pygame.time.delay(25)

    for zombie in my_list:
        zombie.draw()
        zombie.update()
        zombie.death()

    pygame.display.flip()
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
