在 pygame 中创建一个具有多个屏幕/窗口的菜单

如何解决在 pygame 中创建一个具有多个屏幕/窗口的菜单

作为一个项目，我正在尝试创建一个 COVID-19 模拟器，但在创建菜单时遇到了一些问题。我已经获得了基本格式和主要代码，但需要一些帮助来稍微编辑一下以使其按预期正常运行

#Importing the library which i will need and then initializing it so that it works
import pygame
pygame.init()
import pygame,sys
from pygame.locals import *

# initialize font; must be called after 'pygame.init()' to avoid 'Font not Initialized' error
font_title = pygame.font.SysFont("arial",35)
font_para = pygame.font.SysFont("monospace",15)


#Creating colours i may need throughout my menu
BLACK = (0,0)
WHITE = (255,255,255)
RED = (255,0)
GREEN = (0,0)
BLUE = (0,255)

#Creating the basic window for each sceen in my menu
menu = pygame.display.set_mode((999,800))
pygame.display.set_caption('WELCOME TO COVID-19 SIMULATOR')

#Creating a clock which I will need to control the frames within my game(amount of times it refreshes per minute)
clock = pygame.time.Clock()

def Label(screen,text,size,font,color,x,y):
  label = font.render(text,color)
  screen.blit(label,(x,y))

#Creatong the actual menu
Flag = True
click = False
def Menu():
    while Flag == True:
      menu.fill(BLACK)
      title = Label(menu,"COVID-19 SIMULATOR: Main Menu",1,font_title,WHITE,275,150)


      own_sim_button = pygame.Rect(350,290,40)
      saved_sim_button = pygame.Rect(350,390,40)
      referrences_button = pygame.Rect(350,490,40)

      x_mouse,y_mouse = pygame.mouse.get_pos()

      if own_sim_button.collidepoint((x_mouse,y_mouse)):
        if click:
          own_sim()
      if saved_sim_button.collidepoint((x_mouse,y_mouse)):
        if click:
          saved_sim()
      if referrences_button.collidepoint((x_mouse,y_mouse)):
        if click:
          referrences()

      pygame.draw.rect(menu,RED,own_sim_button)
      pygame.draw.rect(menu,saved_sim_button)
      pygame.draw.rect(menu,referrences_button)



      click2= False
      for event in pygame.event.get():
        if event.type == QUIT:
          pygame.quit()
          sys.exit()
        if event.type == KEYDOWN:
          if event.key == K_ESCAPE:
            pygame.quit()
            sys.exit()
        if event.type == MOUSEBUTTONDOWN:
          if event.button == 1:
            click2= True



      pygame.display.flip()
      clock.tick(60)

def own_sim():
  Flag2 = True
  while Flag2 == True:
    menu.fill(BLACK)
    title = Label(menu,"Entering statistics to use for the simulation",150)

  pygame.display.flip()
  clock.tick(60)

def saved_sim():
  Flag2 = True
  while Flag2 == True:
    menu.fill(BLACK)
    title = Label(menu,"Selecting presaved statistcs",150)

  pygame.display.flip()
  clock.tick(60)

def referrences():      
  Flag2 = True
  while Flag2 == True:
    menu.fill(BLACK)
    title = Label(menu,"Referrence Page",150)

  pygame.display.flip()
  clock.tick(60)



Menu()

我的代码没有按预期工作。我期待它的功能类似于下一段代码所示的功能：

import pygame,sys
 
# Setup pygame/window ---------------------------------------- #
mainClock = pygame.time.Clock()
from pygame.locals import *
pygame.init()
pygame.display.set_caption('game base')
screen = pygame.display.set_mode((500,500),32)
 
font = pygame.font.SysFont(None,20)
 
def draw_text(text,surface,y):
    textobj = font.render(text,color)
    textrect = textobj.get_rect()
    textrect.topleft = (x,y)
    surface.blit(textobj,textrect)
 
click = False
 
def main_menu():
    while True:
 
        screen.fill((0,0))
        draw_text('main menu',(255,255),screen,20,20)
 
        mx,my = pygame.mouse.get_pos()
 
        button_1 = pygame.Rect(50,100,200,50)
        button_2 = pygame.Rect(50,50)
        if button_1.collidepoint((mx,my)):
            if click:
                game()
        if button_2.collidepoint((mx,my)):
            if click:
                options()
        pygame.draw.rect(screen,0),button_1)
        pygame.draw.rect(screen,button_2)
 
        click = False
        for event in pygame.event.get():
            if event.type == QUIT:
                pygame.quit()
                sys.exit()
            if event.type == KEYDOWN:
                if event.key == K_ESCAPE:
                    pygame.quit()
                    sys.exit()
            if event.type == MOUSEBUTTONDOWN:
                if event.button == 1:
                    click = True
 
        pygame.display.update()
        mainClock.tick(60)
 
def game():
    running = True
    while running:
        screen.fill((0,0))
        
        draw_text('game',20)
        for event in pygame.event.get():
            if event.type == QUIT:
                pygame.quit()
                sys.exit()
            if event.type == KEYDOWN:
                if event.key == K_ESCAPE:
                    running = False
        
        pygame.display.update()
        mainClock.tick(60)
 
def options():
    running = True
    while running:
        screen.fill((0,0))
 
        draw_text('options',20)
        for event in pygame.event.get():
            if event.type == QUIT:
                pygame.quit()
                sys.exit()
            if event.type == KEYDOWN:
                if event.key == K_ESCAPE:
                    running = False
        
        pygame.display.update()
        mainClock.tick(60)
 
main_menu()

提前感谢您的任何帮助。另外，如果有人能告诉我一种在我的程序中切换红色框并将其替换为文本的方法，我将不胜感激。
