Pong游戏无法显示获胜提示 窗口直接返回主菜单求助

我开发了一款先获得5分即结束的简易Pong游戏，但无法在游戏结束时显示“获胜者是player1/player2”的提示信息，窗口会直接关闭并返回主菜单。以下是该游戏的Igra类代码：

import pygame
from random import randint
from stick import Stick
from loptica import Loptica
from rezultati import Rezultati
import sqlite3

pygame.init()

class Igra:
    def __init__(self, duzinaProzora, sirinaProzora, brIgraca, igrac1, igrac2, igra):

            loptica.rect.y = sirinaProzora/2
            loptica.brzina = [4*randint(-1,1),4*randint(-1,1)]
            while loptica.brzina[0] == 0:

        pygame.display.set_caption("VDPong")
        pygame.display.set_icon(pygame.image.load('ball.jpg'))

        stick1 = Stick ((255,255,0),10,100)
        stick1.rect.x = 25
        stick1.rect.y = sirinaProzora / 2 - 50

        stick2 = Stick ((255,255,0),10,100)
        stick2.rect.x = duzinaProzora - 35
        stick2.rect.y = sirinaProzora / 2 - 200

        lista_spriteova.add(stick1)
        lista_spriteova.add(stick2)
        lista_spriteova.add(loptica)

        while self.igra:

                    self.igra = False
            
            kontrole = pygame.key.get_pressed()

            if self.brIgraca == 2:

                if loptica.brzina[0] >= 9:
                    loptica.brzina[0] == 9
            
            prozor.fill((0,0,255))

pygame.quit()

问题原因 #

当前代码在玩家得分达到5分时，直接通过break跳出主游戏循环，随后立即执行数据库存储操作并调用pygame.quit()关闭窗口，没有预留任何显示获胜提示并等待用户交互的逻辑，导致窗口直接关闭。

修复方案 #

在跳出主循环后，添加一个新的循环来显示获胜提示，等待用户操作（如按下任意键或关闭窗口）后再退出：

修改后的关键代码片段 #

if bodoviA == 5 or bodoviB == 5:
            rezultat = str(bodoviA) + ":" + str(bodoviB)
            break
        
        # --- 新增：显示获胜提示的循环 ---
        winner = igrac1 if bodoviA ==5 else igrac2
        font_large = pygame.font.Font(None, 80)
        winner_text = font_large.render(f"获胜者是 {winner}", 1, (255, 0, 0))
        text_rect = winner_text.get_rect(center=(duzinaProzora/2, sirinaProzora/2))
        
        waiting = True
        while waiting:
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    waiting = False
                    self.igra = False
                if event.type == pygame.KEYDOWN:
                    waiting = False
            
            # 绘制背景和原有元素
            prozor.fill((0,0,255))
            pygame.draw.line(prozor, (255,255,0) , [duzinaProzora/2, 0], [duzinaProzora/2, sirinaProzora], 5)
            lista_spriteova.draw(prozor)
            
            # 绘制分数和玩家名称
            font = pygame.font.Font(None, 50)
            text = font.render(str(bodoviA), 1, (255,255,0))
            prozor.blit(text, (duzinaProzora/2-60,255))
            text = font.render(str(bodoviB), 1, (255,255,0))
            prozor.blit(text, (duzinaProzora - duzinaProzora/2 + 40,255))
            text = font.render(str(igrac1), 1, (255,255,0))
            prozor.blit(text, (duzinaProzora/4,20))
            text = font.render(str(igrac2), 1, (255,255,0))
            prozor.blit(text, (duzinaProzora - duzinaProzora/4-40,20))
            
            # 绘制获胜提示
            prozor.blit(winner_text, text_rect)
            
            pygame.display.flip()
            vrijeme.tick(60)
        # --- 结束新增部分 ---
        
        rez = Rezultati(igrac1, igrac2, rezultat)
        rez.bazaRezultata(igrac1,igrac2,rezultat)

pygame.quit()

修复说明 #

1. 确定获胜者：通过判断bodoviA或bodoviB是否等于5，确定获胜玩家。
2. 创建提示文本：用更大的字体生成获胜提示，并居中显示在窗口。
3. 等待循环：新增一个循环，处理退出事件和按键事件，只有当用户关闭窗口或按下任意键时，才结束循环继续后续流程。
4. 完整绘制：在等待循环中重新绘制游戏界面的所有元素（背景、分数、玩家名称、球和挡板），再叠加获胜提示，保证界面完整。
