如何解决我想添加一个屏幕，说要用10秒的计时器进行升级，然后继续游戏

在我制作的游戏中清除4级之后，我想添加一个计时器。计时器应为10秒，其中应显示“正在升级”，然后继续到5级。我该如何做？我在这方面遇到麻烦，希望得到您的帮助。我尝试了许多不同的方法，但没有一个起作用。请帮助，因为我需要在8月25日之前提交此项目。

我当前的代码：

import pygame
from pygame import mixer

pygame.font.init()
pygame.init()

# THE SCREEN SIZE
WIDTH,HEIGHT = 800,600
WIN = pygame.display.set_mode((WIDTH,HEIGHT))

# THE GAME NAME
pygame.display.set_caption("The Space Walker")

# ENEMIES
REDEX = pygame.image.load("REDEX.png")
GENEX = pygame.image.load("GENEX.png")
BREX = pygame.image.load("BREX.png")
BOSS = pygame.image.load("Boss.png")

# THE PLAYER
player = pygame.image.load("BLShip.png")
THESPACEWALKER = pygame.image.load("SPACEWALKER.png")

# ENEMY LASERS

GENEXASER = pygame.image.load("GENEXASER.png")

# PLAYER LASER

解决方法

也许您可以执行以下操作：

import pygame
import time
pygame.init()

D = pygame.display.set_mode((500,500))
font = pygame.font.Font(pygame.font.get_default_font(),20)
start = time.time()
def display(waittime):
    now = time.time()
    surf = font.render("UPGRADING",True,(0,255,0))
    usurf = font.render("UPGRADED",0))
    timer = now - start
    if timer < waittime:
        pygame.draw.rect(D,0),(100,20,timer * 20,50))
        D.blit(surf,(150,150))
    else:
        D.blit(usurf,150))
     
while True:
    D.fill((255,255))
    pygame.event.get()

    display(10)
    
    pygame.display.flip()
, 
pause_time = 0

def count(level):

    time_left = 10

    if level == 4:

        if trig == 1

            time = int(pygame.time.get_ticks()/1000)

            trig = 2

        while time_left != 0:

            time_left=(10-(int(pygame.time.get_ticks()/1000) - time))

            myfont = pygame.font.Font(yourpreferedfont,yourpreferedsize)

            time_left_text = myfont.render(time_left,(255,255))

            WIN.blit(time_left_text,(x,y))

在应有的位置插入代码，如果它不起作用，我也无法测试它，因为我没有您的图像，这会给我一个错误。
