如何在游戏中添加回放按钮

Question

我正试图为我的游戏制作一个重播按钮，当你死亡时，游戏会暂停，直到你按下空格键重置游戏，这样你就可以再次玩了。我在pygame中使用python。如果你能解决这个问题，请照做！这将是我的一天。如果可能的话，请包括修复的代码以及将其放在哪里，因为我是python的新手。下面的源代码是我正在开发的游戏。

import pygame

pygame.init()

HEIGHT = 600
TRASH = (110, 110, 110)

player_pos = [400, 475]
player_size = 50
screen = pygame.display.set_mode((WIDTH, HEIGHT))
enemy_size = 50

FPS = 120
enemy_pos = [random.randint(0, WIDTH - enemy_size), 0]
enemy_list = [enemy_pos]
game_over = False
score = 0
clock = pygame.time.Clock()
myFont = pygame.font.SysFont("monospace", 35)
pygame.display.set_caption('Crab Dodge,  By: ChanceMeteor515')
pygame.mouse.set_visible(0)

def drop_enemies(enemy_list):
if len(enemy_list) < 9:
x_pos = random.randint(0, WIDTH - enemy_size)
y_pos = 10
enemy_list.append([x_pos, y_pos])

def draw_enemies(enemy_list):

pygame.draw.rect(screen, TRASH, (enemy_pos[0], enemy_pos[1], enemy_size, enemy_size))

好吧，我已经完成了你想要的，但这需要Tkinter，因为我有点懒。
